Whatever misfortune you face, just hold up your head and face it with a smile! I got to know this from a musical soul.
The other day I was feeling quite 36 , having just been laid off from my job.
With so many 37 to pay, I was wondering what was going to happen to my family.
I got off the bus when I heard piano music and singing rising above the noise of the 38 . I walked a bit slower, trying to find out where it was coming from. Through the 39 I saw a young lady sitting at a piano with a box next to her.
2
She was singing songs about love and her sweet voice 40 me a bit. Then I
stood there watching her playing, thinking that it must take 41 to perform on her
own in front of hundreds of people she didn’t know.
She might have felt my 42 for she occasionally looked in my direction.
By now I was telling myself that I could at least tell her how good she sounded. I
walked 43 and put some money in her box and she expressed her thanks with a smile on her face.
I asked her 44 , ―Why are you playing the piano in the middle of this crowded place?‖
She explained to me that she sees so many 45 people in the world that she is trying to relieve the pain by 46 motivational music.
Instead of continuing my way home, I said to her, ―I have been going through a
47 time lately, but you’ve made me 48 again.‖
―I’m happy that I could be 49 to you,‖ she replied. ―Why are you so sad?‖
I told her my story and said, ―I’m not so 50 about what to do….‖
―You see, here’s the 51 ,‖ she responded. ―When you were walking, your head was down.‖ She looked me in the eyes and went on, ―Don’t look defeated, because 52 comes in different ways and if your head is down you might never see it. You should 53 more … lift your head up.‖
I was really 54 by what she said! I did hold my head up and soon got through the difficult time.
So 55 in trouble just face it bravely and you are sure to overcome your difficulty sooner or later.

出最佳选项,并在答题卡上将该项涂黑。
A
Wherever life takes you after A-level results day, it’s likely to bring increased
independence. That means it’s time to take care of yourself.
Students, take note. When you arrive at university, make sure you register with a doctor near your term-time address. If there is a university doctor at your institution, they will be your best choice. If not, ask student services for a recommendation. Once registered, do everything you can to make sure you never have to pay them a visit. Don’t take unnecessary health risks.
Cook meat thoroughly. Throw food away if it’s out of date. Clean up after yourself. Food poisoning can be harmful, but it’s easy to avoid if you pay due care and attention.
University often brings a certain lifestyle, and while that’s usually a whole lot of fun, it can quickly tip into a whole lot of sorrow. Know your limits when it comes to alcohol. Habitual drinking can be dangerous, and while every student will have nights of excess, these should be the exception, not the norm. Look out for your friends, too. If you’re worried about alcohol or substance abuse, visit alcoholics-anonymous.org.uk
or ukna.org for free and confidential support.
Anyone living with teenagers and young adults, especially in environments such as halls of residence, must accept that germs (细菌) will be shared. Bugs and colds
will spread like wildfire. Living communally brings certain health risks, and meningitis is probably the most serious of these. Symptoms include a rash, stiff neck and an aversion to bright lights. It’s rare, but seek immediate medical attention if you’re concerned (meningitis.org).
Gappers, meanwhile, may need to consider specific health risks. If you’re planning a trip abroad, especially in rural areas of poor countries, make sure you get the necessary vaccinations (预防注射) in good time before you leave.
Research these at www.netdoctor.co.uk. You should be able to get everything you need from your doctor, although you may have to give them notice and you may have
4
to pay, even on the NHS (英国国家医疗服务体系). If you also need to take
medication while you’re away, such as anti-malarials, do it faithfully.
On a general note, whoever you are, wherever you are and whatever you do with your time, never walk alone at night, especially in quiet and badly lit areas. Always carry your phone. Never get in an unlicensed cab. Be careful who you trust. Respect your new independence, and keep yourself safe.
C56. This passage is mainly intended for the students _________.
A. who enjoy university life
B. who live outside the campus
C. who are going to university
D. who want to keep fit at university
B57. The underlined word ―meningitis‖ in Paragraph 5 probably refers to _________.
A. a system about health risks B. a serious infectious illness
C. anti-malaria medicine D. wide-spread germs and
bugs
D58. If students want to remove their worries about certain symptoms, they can visit ________.
A. www.netdoctor.co.uk B. ukna.org
C. alcoholics-anonymous.org.uk D. meningitis.org
A59. Which of the following statements is true?
A. Students are allowed to take medication even when they are away.
B. Students have to register with a doctor for free medical care.
C. Students prefer to live in environments such as halls of residence.
D. Students have to avoid health and security risks to be independent.

C
Driving speeds have largely stabilized, and nowadays, safety concerns are important and reducing road accidents to minimum is a must. So, automakers are focused on safety systems more than ever before.
Given the emphasis on improving safety, it’s possible that well-known phrases
such as ―live fast and die young‖ may lose their meaning as innovative (创新的) new
devices are built into cars and trucks and other things that go.
Many of the new safety systems that are being added to high-end vehicles are computer-assisted technologies that transfer some of the vehicle’s operations to the vehicle itself, rather than relying only on the driver’s decision-making skills.
For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking when its built-in sensors detect a potential object ahead. The predictive brake assist basically places the vehicle’s braking system on alert, which helps the system to slow down the car in as little time and as short a distance as possible.
Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects based on simple patterns, such as other vehicles vs. a person.
6
What’s more, built-in ―active systems‖, i.e., predictive precollision (可预测碰撞)
systems, will provide drivers with advance detection of potential contact between vehicles. These systems compute the relative movement of the objects and detect possible dangerous intersections (交点).
What technological developments have enabled innovations like predictive precollision systems? Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure communications.
These communication links allow highways to provide a vehicle’s owners with services such as renting a movie during the trip, as well as reduce reaction delays when medical care is needed due to a crash.
Despite these new technologies, drivers cannot take safety for granted.
Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the road and your hands on the steering wheel (方向盘).
D63. ―Predictive Precollision‖ can be used to _________.
A. detect possible dangerous crossroads
B. compute the relative movement of the contacting vehicles
C. brake the car automatically in as little time as possible
D. detect potential contacts between vehicles in advance
C64. Which of the following statements is NOT true?
A. Advanced safety systems make driving an easier job.
B. Automakers pay more attention to safety system than before.
C. New advanced technology makes the vehicle operation rely only on the vehicle itself.
D. Drivers are still expected to drive carefully despite the built-in advanced safety system.
C65. We can conclude that the new technology will _________.
A. put an end to road accidents
B. force people to obey traffic laws
C. see a wide use in the future
D. ensure the quality of medical care
B66. Which of the following would best serve as the title for the passage?
A. Live fast, die young B. New systems, safer driving
C. New technology, relaxed drivers D. High-end vehicles, big

innovation
D.
The silent young woman in bed number six is called Jasmine. So am I, but names are only superficial things, floats on the surface of the water, and we share deeper connections than that. That is why she fascinates me—why I spend my off-duty time
sitting beside her.
Today is difficult. The ward (病房) is full of patients and I am kept busy
emptying bed-pans, filling out forms, changing dressings. Finally, late in the afternoon, I get a few moments to make coffee, to take it over to the orange plastic chair beside her bed. I am thankful to be off my feet, glad to be in her company once again.
―Hello, Jasmine,‖ I say, as if greeting myself.
She does not reply. Jasmine never replies. She is down too deep.
She has been sea-damaged. I too am the daughter of a fisherman, so I choose my words like fish-hooks, cast them into her ears, imagine them sinking down through cold, dark water. Down to wherever she may be.
―I have little time today,‖ I tell her, touching her hair.
With Jasmine, it is always difficult not to touch. She is that rare thing, a truly beautiful woman. Because of this, people invent reasons to walk by. I catch them looking, drinking her in, feeding on her. They are barracuda (梭鱼), all of them.
Great beauty is something Jasmine and I do not share. I am glad of it.
―Your father may be here soon,‖ I say. ―Last week he said he would come.‖
Jasmine says nothing. Her left eyelid flickers, perhaps.
It is two months since the incident on her father’s fishing boat, since she fell overboard, sank, became entangled in the nets. It was some time before anyone noticed, then there was panic. Her father hauled her back on board and sailed for home. When he finally arrived, he carried ashore what he thought was his daughter’s body.
―Jasmine,‖ I whisper. I want her to take our baited (用作诱醒的) name. I want
her to swallow it.
Fortunately, there was a doctor in the village that morning, a young man visiting relatives. It was he who brought this drowned woman back from the brink, he who told me her story. She opened her eyes, he said, looked up at her father and spoke a single word—then sank again, this time into coma.
Barracuda. That is what Jasmine said.
When her father visits, he touches her hair, kisses her cheek, sits in the orange plastic chair at the side of her bed and holds her hand. Like my own father, he has the big, brown, life-roughened hands of a fisherman. He too smells of the sea, and pretends he is a good, simple man.
Jasmine. We share so much, we are almost one.
I remember early mornings, my hair touched to wake me, my father lifting me half-asleep from my bed, carrying me, dropping me into his boat. His voice rough in my ear, his hands rough on my skin. I never wanted to go, but I was just a child. He did as he wished.
8
I remember salt water, hot sun, my mother shrinking on the shore. I remember
the rocking of the boat, the screams of the seagulls.
―Jasmine, you have a life inside you. Can’t you hear it calling?‖
Nothing.
The ward door bangs, and I see Jasmine’s father walking towards us, carrying
flowers. He smiles at me. Even in death, my own child had my father’s smile, and Jasmine’s will have this man’s. I know it.
He stops by her bed and touches her hair. Something stirs deep inside me. I
watch Jasmine’s eyelids, waiting for her to bite.
C67. Why does the author show special sympathy for Jasmine?
A. They share the same name. B. Jasmine looks very fascinating.
C. They have much in common. D. Jasmine’s father is very pitiful.
D68. From the passage we can learn that Jasmine’s father _________.
A. comes to see his daughter every day
B. is a good and simple man in the author’s eyes
C. took his daughter out to the sea against her will
D. thought his daughter dead when back to the shore A69. What kind of situation is Jasmine in now?
A. She is unconscious. B. She is nearly dying.
C. She is completely deaf. D. She is in a bad mood.
D70. We can learn from the story that __________.
A. ihe author enjoys her early life on the sea
B. Jasmine was pulled out of water without delay
C. the author spends her duty time attending Jasmine
D. it was a young doctor who happened to save Jasmine 61—65 BADCC 66—70 BCDAD

sometimes get into hard times. However, we must never lose hope for only through determination and discipline will we be able to reach personal growth. The following tips may help you to achieve your goals for personal growth.
Find challenges
If you don’t find any challenges to your life, don’t just let it be but find them yourself. You should understand that staying too much in your comfort zone would just cause you to remain where you are and therefore never improve. So try to find new challenges that would further develop your strengths and therefore achieve their peak performance.
Always have a positive mindset (思维模式)
You should develop a positive mindset, as this would be useful when you face any challenge along the way. Through this type of mindset, you will be able to continue with your life no matter how hard the challenge you face is. You should always find a reason to be happy, which would fuel you to go on further and further until you reach your destination.
You are not alone and you shouldn’t let yourself be
This is a very important factor. Sometimes we are so stubborn about doing things on our own that we don’t ask others for help. Generally speaking, doing things by yourself is not wrong, and, in fact, it’s even preferred to be independent. However, there are really instances in our life that we need to ask others for help. You shouldn’t see this as being weak, and other people won’t think less of you if you do this. We humans are communal individuals and we could achieve more in this world if we help one another. So don’t hesitate to ask for help if you need it, and also lend a hand to others when they need you.
Plan
When you want to achieve something, don’t be in a rush. You need to make good
preparations before doing it, that is, to plan your overall course of action in advance. Create a goal that you are ready to bet your life on, and check it to see if it is really the goal you want to attain before you give it your all without any second thoughts. When you’re sure about it, plan the ways to achieve it, and to evaluate if your process is

One possible version:
Young people are often at a loss when it is up to them to choose their way of life.
In the picture, we can see a man walking on the road of life, facing many choices and wondering which way to take. In our daily life, we often have similar situations and have to make decisions independently.
In order to make a decision that we won’t regret, we should follow these two principles: thinking before acting and never missing any opportunities that arise. On one hand, we should have an objective judgment about ourselves while maintaining a clear idea about the world around us. On the other hand, opportunity is open to everyone and we should make good use of it when it comes. ―Opportunities are only
for the prepared minds.‖
12
In my opinion, as high school students, we should value our time in school and get prepared for the future. When faced with choices, we should remember that using the mind and taking advantage of good opportunities will lead to success. (153 words)

Whatever misfortune you face, just hold up your head and face it with a smile! I got to know this from a musical soul.
The other day I was feeling quite 36 , having just been laid off from my job.
With so many 37 to pay, I was wondering what was going to happen to my family.

She was singing songs about love and her sweet voice 40 me a bit. Then I

She explained to me that she sees so many 45 people in the world that she is trying to relieve the pain by 46 motivational music.
Instead of continuing my way home, I said to her, “I have been going through a 47 time lately, but you’ve made me 48 again.”
“I’m happy that I could be 49 to you,” she replied. “Why are you so sad?”
I told her my story and said, “I’m not so 50 about what to do….”
“You see, here’s the 51 ,” she responded. “When you were walking, your head was down.” She looked me in the eyes and went on, “Don’t look defeated, because 52 comes in different ways and if your head is down you might never see it. You should 53 more … lift your head up.”
I was really 54 by what she said! I did hold my head up and soon got through the difficult time.

Wherever life takes you after A-level results day, it’s likely to bring increased independence. That means it’s time to take care of yourself.
Students, take note. When you arrive at university, make sure you register with a doctor near your term-time address. If there is a university doctor at your institution, they will be your best choice. If not, ask student services for a recommendation. Once registered, do everything you can to make sure you never have to pay them a visit. Don’t take unnecessary health risks.
Cook meat thoroughly. Throw food away if it’s out of date. Clean up after yourself. Food poisoning can be harmful, but it’s easy to avoid if you pay due care and attention.
University often brings a certain lifestyle, and while that’s usually a whole lot of fun, it can quickly tip into a whole lot of sorrow. Know your limits when it comes to alcohol. Habitual drinking can be dangerous, and while every student will have nights of excess, these should be the exception, not the norm. Look out for your friends, too. If you’re worried about alcohol or substance abuse, visit alcoholics-anonymous.org.uk or ukna.org for free and confidential support.
Anyone living with teenagers and young adults, especially in environments such
调菌as halls of residence, must accept that germs () will be shared. Bugs and colds will
spread like wildfire. Living communally brings certain health risks, and meningitis is
probably the most serious of these. Symptoms include a rash, stiff neck and an aversion to bright lights. It’s rare, but seek immediate medical attention if you’re concerned (meningitis.org).
Gappers, meanwhile, may need to consider specific health risks. If you’re planning a trip abroad, especially in rural areas of poor countries, make sure you get
调防注射the necessary vaccinations () in good time before you leave.
Research these at www.netdoctor.co.uk. You should be able to get everything you need from your doctor, although you may have to give them notice and you may have
英家调服调系国国医体to pay, even on the NHS (). If you also need to take medication
while you’re away, such as anti-malarials, do it faithfully.
On a general note, whoever you are, wherever you are and whatever you do with your time, never walk alone at night, especially in quiet and badly lit areas. Always carry your phone. Never get in an unlicensed cab. Be careful who you trust. Respect your new independence, and keep yourself safe.

Driving speeds have largely stabilized, and nowadays, safety concerns are important and reducing road accidents to minimum is a must. So, automakers are focused on safety systems more than ever before.
Given the emphasis on improving safety, it’s possible that well-known phrases
调新的such as “live fast and die young” may lose their meaning as innovative () new
devices are built into cars and trucks and other things that go.
Many of the new safety systems that are being added to high-end vehicles are computer-assisted technologies that transfer some of the vehicle’s operations to the vehicle itself, rather than relying only on the driver’s decision-making skills.
For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking when its built-in sensors detect a potential object ahead. The predictive brake assist basically places the vehicle’s braking system on alert, which helps the system to slow down the car in as little time and as short a distance as possible.
Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects based on simple patterns, such as other vehicles vs. a person.
可调调撞碰What’s more, built-in “active systems”, i.e., predictive precollision ()
systems, will provide drivers with advance detection of potential contact between vehicles. These systems compute the relative movement of the objects and detect
交点possible dangerous intersections ().
What technological developments have enabled innovations like predictive precollision systems? Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure communications.
These communication links allow highways to provide a vehicle’s owners with services such as renting a movie during the trip, as well as reduce reaction delays

when medical care is needed due to a crash.
Despite these new technologies, drivers cannot take safety for granted.
Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the road and your hands on the steering wheel 方向调().
D63. “Predictive Precollision” can be used to _________.
A. detect possible dangerous crossroads
B. compute the relative movement of the contacting vehicles
C. brake the car automatically in as little time as possible
D. detect potential contacts between vehicles in advance
C64. Which of the following statements is NOT true?
A. Advanced safety systems make driving an easier job.
B. Automakers pay more attention to safety system than before.
C. New advanced technology makes the vehicle operation rely only on the vehicle itself.
D. Drivers are still expected to drive carefully despite the built-in advanced safety system.
C65. We can conclude that the new technology will _________.
A. put an end to road accidents
B. force people to obey traffic laws
C. see a wide use in the future
D. ensure the quality of medical care
B66. Which of the following would best serve as the title for the passage?
A. Live fast, die youngB. New systems, safer driving
C. New technology, relaxed drivers D. High-end vehicles, big
innovation

The silent young woman in bed number six is called Jasmine. So am I, but names are only superficial things, floats on the surface of the water, and we share deeper connections than that. That is why she fascinates me—why I spend my off-duty time sitting beside her.
病房Today is difficult. The ward () is full of patients and I am kept busy
emptying bed-pans, filling out forms, changing dressings. Finally, late in the
英调调卷 第 调 ;共7 14调,
afternoon, I get a few moments to make coffee, to take it over to the orange plastic chair beside her bed. I am thankful to be off my feet, glad to be in her company once again.
“Hello, Jasmine,” I say, as if greeting myself.
She does not reply. Jasmine never replies. She is down too deep.
She has been sea-damaged. I too am the daughter of a fisherman, so I choose my words like fish-hooks, cast them into her ears, imagine them sinking down through cold, dark water. Down to wherever she may be.
“I have little time today,” I tell her, touching her hair.
With Jasmine, it is always difficult not to touch. She is that rare thing, a truly beautiful woman. Because of this, people invent reasons to walk by. I catch them
梭调looking, drinking her in, feeding on her. They are barracuda (), all of them.
Great beauty is something Jasmine and I do not share. I am glad of it.
“Your father may be here soon,” I say. “Last week he said he would come.”
Jasmine says nothing. Her left eyelid flickers, perhaps.
It is two months since the incident on her father’s fishing boat, since she fell overboard, sank, became entangled in the nets. It was some time before anyone noticed, then there was panic. Her father hauled her back on board and sailed for home. When he finally arrived, he carried ashore what he thought was his daughter’s body.
“用作调醒的Jasmine,” I whisper. I want her to take our baited () name. I want
her to swallow it.
Fortunately, there was a doctor in the village that morning, a young man visiting relatives. It was he who brought this drowned woman back from the brink, he who told me her story. She opened her eyes, he said, looked up at her father and spoke a single word—then sank again, this time into coma.
Barracuda. That is what Jasmine said.
When her father visits, he touches her hair, kisses her cheek, sits in the orange plastic chair at the side of her bed and holds her hand. Like my own father, he has the big, brown, life-roughened hands of a fisherman. He too smells of the sea, and pretends he is a good, simple man.
Jasmine. We share so much, we are almost one.
I remember early mornings, my hair touched to wake me, my father lifting me half-asleep from my bed, carrying me, dropping me into his boat. His voice rough in my ear, his hands rough on my skin. I never wanted to go, but I was just a child. He did as he wished.
I remember salt water, hot sun, my mother shrinking on the shore. I remember the rocking of the boat, the screams of the seagulls.
“Jasmine, you have a life inside you. Can’t you hear it calling?”
Nothing.
The ward door bangs, and I see Jasmine’s father walking towards us, carrying flowers. He smiles at me. Even in death, my own child had my father’s smile, and Jasmine’s will have this man’s. I know it.
He stops by her bed and touches her hair. Something stirs deep inside me. I

One possible version:
Young people are often at a loss when it is up to them to choose their way of life.
In the picture, we can see a man walking on the road of life, facing many choices and wondering which way to take. In our daily life, we often have similar situations and have to make decisions independently.
In order to make a decision that we won’t regret, we should follow these two principles: thinking before acting and never missing any opportunities that arise. On one hand, we should have an objective judgment about ourselves while maintaining a clear idea about the world around us. On the other hand, opportunity is open to everyone and we should make good use of it when it comes. “Opportunities are only for the prepared minds.”
In my opinion, as high school students, we should value our time in school and get prepared for the future. When faced with choices, we should remember that using the mind and taking advantage of good opportunities will lead to success. (153 words)
