That holiday morning I didn’t have to attend school. Usually, on holidays, Mother
36 me to sleep in. And I would certainly take full advantage of it. On this particular morning, 37 , I felt like getting up early.
I stood by my window overlooking the 38 , having nothing better to do. But as it turned out, I was soon to learn about something 39 in life.
As I watched several people go by, get into their cars and go off, I 40 an old man on a bicycle with a bucket on its 41 and a basket of rags and bottles on its back-carriage. He 42 from one car to another, washing and cleaning them. From the water on the ground, it seemed that he had already 43 washing and cleaning about a dozen or more cars. He must have begun to work quite early in the morning.
Several thoughts 44 my mind as I watched him work. He wasn’t well-dressed. He had on a pair of shorts and a(n) 45 T-shirt. The bicycle he rode was not by any means the kind modern 46 would want to be seen riding on. But he seemed 47 with life. There he was, working hard at his small business  48  at passers-by and stopping to chat now and then  49   elderly men and women on their way to the market nearby.
There was a noticeable touch of 50 in the way he seemed to be doing things — 51 the windscreen, then standing back to admire it; scrubbing the wheels and  52 , standing back to see what they look like after the scrub.
It was a 53 to learn, I felt. At no age need one have to beg for a 54 if one has good health and is willing to work hard. For a while I felt 55 of myself. Young as I am—just sixteen, and there was this old man who must have been usefully engaged perhaps before the sun appeared above the horizon.

第三部分：阅读理解（共两节，40分）
第一节（共15小题；每小题2分，共30分）
阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。
A
When the musical sound rings out, you immediately reach for your pocket ready to have a chat. But although you probably use it all the time, have you ever stopped to think about the manners related to talking on the phone?
If you haven’t, here are some tips to guide you.
· Always give the person you are calling plenty of time to get to the phone before you hang up. If the person who answers is not the one you want, give your name and ask if you may speak to the person you want.
· Think about the time you call people. Try not to call too early in the morning (before about 9: 00) or too late at night (after about 9:30). Also try not to call at mealtimes.
· If you go by plane to visit your relatives at Christmas, remember to follow airline instructions. Cell phones must be turned off as soon as the plane doors are closed and remain so until the doors open again on arrival.
· When face-to-face with someone, do not talk on the phone. It is rude to be on the phone when a waiter is trying to take your order in a restaurant, or when you are returning the shoes you have just been trying on in a shop.
Finish any face-to-face business before taking a call. Continuing to use the phone while nodding to the person in front of you is quite impolite.
· When in a restaurant with your friends, keep phone conversations short. Make a call only if it is important. Practice speaking in a low voice. If no one looks your way, you’ve got it.
· If you go to a theatre, a concert or a cinema, consider the other people around you. Check that your phone is “off” before you enter. If you are expecting a very important call, put your phone on “ vibrate” (振动) and run for the exit as soon as you feel it. If you forget both “off” and “vibrate” and your phone rings, don’t answer it, turn it off straight away.
56. Which is true according to the passage above?
A. You may call people anytime as you like.
B. You may talk loudly on the phone at dinner in the restaurant.
C. You may keep on talking on the phone while greeting somebody.
D. You may call people as soon as you get on the plane, but not after the doors are closed.
57. We may infer from these tips that _____.
A. some people don’t pay much attention to manners while making cell phone calls
B. you may ask to leave a message unless the person you are calling is in
C. calling people too early or too late in the morning is not polite
D. almost everyone has got a cell phone
58. What does the underlined sentence “…you’ve got it ” mean in the passage?
A. You have succeeded in making a call without disturbing others.
B. You have made the phone call brief and interesting.
C. You’ve got the message you are waiting for.
D. You have made a phone call secretly.
59. From the tips given above, we can decide the writer is sure to share the opinion that _____.
A. like the saying “clothes make a man”, nowadays cell phones make a man
B. as the old saying goes, money talks; nowadays cell phones talk
C. the way we use the cell phones tells what we are like
D. we are what cell phones we use

B
When the population of the port town began to suffer from poisoning, the police came to find the cause of the poison. They thought someone was poisoning the people on purpose but no one knew how it was possible. Soon people took the position that the pork was poisoned. It was a popular food everyone ate and it could have possibly made everyone sick. Anyone who had possession of pork would throw it out. Even the poorest of the poor wouldn’t eat pork. Signs were posted on poles and letters were sent to everyone to warn people of the pork. Shortly afterwards, even policemen in high positions were also getting sick.
Soon it became political and popular. Politicians rushed to the town to talk about politics and promised how they would find the solution if they were elected. Everyone was so sick that they didn’t care about politics. Everyone was in a position where he or she didn’t know what to do anymore. They went to the post office to mail posts out asking for help. The poor town didn’t know how to deal with the situation.
One day, a well-known scientist from New York came to the town with a huge box containing many instruments and his possessions. He went to pools and the port and made measurements. He was quiet and polite. Then one day he made a speech at a newspaper meeting-room to announce his findings.
“I am sorry to say your water supply is so heavily polluted; it is poisoned. I know who has been poisoning you all for such a long time. It is you who have been poisoning yourselves with pollution. A great deal of rubbish has been thrown into the water day after day. No one here has taken good care of the environment. It is no wonder all of you have been sick.” Shocked at the news, the people present were lost in thought.
60. Which is the correct order of the facts described in the story?
a. People suffered from poisoning.
b. Politicians came to make promises.
c. People began to realize the real cause.
d. Pork was thrown away.
e. The water there was polluted.
f. A scientist came to check the water.
A. e, a, d, b, f, c B. e, a, d, c, f, b
C. a, e, b, d, c, f D. f, c, d, b, e, a
61. Which of the following statements is correct?
A. Everyone was so sick of politics that they didn’t care about those politicians.
B. According to the scientist from New York, not all the population in the town have taken good care of the environment.
C. The reason why the people in the town got sick was that they ate the pork poisoned by the heavily polluted water.
D. If the people in the town hadn’t polluted the water supply, they would not have suffered from poisoning or sickness.
62. After reading the passage, we can infer that ________.
A. politicians took every chance to make themselves elected
B. pork was the main food of the people in the town
C. people in the town were not well-educated
D. even some police officers were getting ill

C
Are you preparing for a big test? If so, you may want to go play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels (血管), including those in the brain, stronger and more fully developed. Dr. Cameron is sure that this allows people who exercise to think better. As she says, “while we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”
The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. Even a little movement can show big results. Margaret Barnes, a scientist, also believes in the importance of exercise. She thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. “Babies need movement that encourages and excites their five senses. They need to set up a connection between motion and memory. In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.
Older people can develop their brains as well. Cornell University studied a group of seniors who have a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tai-chi helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main aim is to increase the brain’s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.
63. What is the main idea of this passage?
A. How exercise makes people strong.
B. How to get good scores on a test.
C. How exercise helps the brain.
D. How the brain can change.
64. According to the passage, what is the connection between exercise and brain development?
A. Exercise helps make our blood vessels.
B. Physical exercise helps us think better.
C. The brain needs special mental exercise.
D. The more exercise, the bigger the brain.
65. The smallest amount of exercise required to gain any benefit is _____.
A. three hours per week B. 40 hours per week
C. three hours per day D. 40 hours per month
66. Why is yoga suggested for seniors?
A. It does good to the joints of old people.
B. It does not increase the heart rate.
C. It includes learning new actions.
D. It can be done in groups.


D
Recognized as the largest desert in the world, the Sahara Desert runs across North Africa, covering over 3 million square miles from the Atlantic Coast to the Nile River Valley. Except for an occasional oasis，this vast land is mainly made up of sand, stones, and worn out mountains. The burning sun causes daytime temperatures to rise to nearly 70 degrees in the shade, and days without rain commonly last for years.
Paintings found on the walls of caves in the Sahara Desert suggest that a few thousand years ago, large quantities of plants grew there and covered the desert floor. Many curious and unusual insects, birds and animals got enough food that allowed them to grow and reproduce. At that time, huge river systems and many oases supported growing communities where a large number of people lived.
Research scientists believe that the land became a desert for several reasons. For centuries people there have wandered from place to place in search of food, water, and grazing (吃草) land for their animals. These people have always considered the number of animals they have as a sign of wealth. It is considered more important to have 100 sick and starving animals than 15 healthy ones. The large herds (群) have been allowed to go freely and graze on desert plants and grass. Over time, large sections of land have been left uncovered. In addition to allowing overgrazing, these people cut down whatever trees they could find and used them for firewood. The sand was unable to hold on to the great heat of the day, so nighttime temperatures often drop below freezing and nothing was left to hold the soil together.
Scientists have been studying different ways to bring back the green desert. Through research and experiments, they hope to be able to produce plants that will once again support the life there. Huge holes filled with much water lie under the desert surface. Scientists believe this rainwater simply flew down through the sand over hundreds of years and collected in the big, rocky holding tanks. By making use of the sun’s power, scientists in the Sahara have made experiments in which they got huge amount of electricity. This electricity was then used to operate drilling machines and pumps to pull the rainwater from the underground tanks. By drilling the hole one mile deep into the floor of the desert, one machine was able to recover more than 80 gallons of ice-cold water each second, or 288,000 gallons per hour.
Scientists have had some success turning this wasteland into useful farmland. Today the desert is dotted with huge wheat fields watered by a system of pipes that carry water from the underground tanks. Farmers have also learnt that plants grow better if seeds are planted next to stones. Studies show that stones provide protection from the sun, allowing seeds to grow in a shady and cool environment. In addition to that, greenhouses have been built to protect plants from the sunshine so that less water is needed. Another idea is to grow plants that can live on a diet of salt water, since the ocean is so near to the desert.
67. What will probably happen if the local people continue their customs and traditions?
A. The desert will continue to be enlarged.
B. Tourists will begin traveling to North Africa.
C. More oases will begin to appear across the desert.
D. The number of healthy animals will become larger.
68. Which of the following statements is a fact presented in the passage?
A. The desert is rich in beautiful color and scenery.
B. Camels can go for days without drinking any water.
C. The Sahara will one day become a beautiful garden.
D. Large river systems once supported many communities.
69. The author of the passage provides evidence that scientists are _____.
A. pleased by the progress but do not have the money to continue
B. discouraged by the poor results of their experiments
C. hopeful about the chances of life coming back to the desert
D. troubled by the lack of water found underground
70. Which of the following is the best summary of this passage?
A. Drilling machines help to water the desert floor and make plants and animals alive.
B. Scientists have been able to turn this large wasteland into a successful farming community.
C. So much soil has become sand that the desert will never be able to support life as it once did.
D. The desert no longer supports plenty of life, but researchers hope to change it with new scientific techniques.

第二节 （共5小题；每小题2分，共10分）
根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Selfie
Social media and the mobile web have given rise to a strange phenomenon called the selfie. It refers to a picture of yourself, usually shared on any social networking website.
71 Some selfies are extreme close-ups, and others show part of an arm held straight outward. A few of them even feature the subject standing in front of a bathroom mirror.
Everyone takes selfies, but the younger crowd seems to be especially involved in the trend. Young people are relatively heavier digital users. They are interested in staying connected to their friends. 72
There are also kinds of psychological factors driving people to take a selfie and upload it to a social networking site. 73 A quick and easy way to attract other's attention is to get “likes” and comments from friends. Secondly, it's human nature to show off your own great achievements. When you feel good about yourself or look good, it's far too easy to take out your phone and document it all through one or several selfies. 74 That's right. Sometimes people are bored at work, bored at school, bored at home and even bored on the toilet. Last but not least, social media is about being social! If that means uploading as many selfies as possible, then so be it. It's fun, and it's a cool way to sort of document your own life.
Finally, there are things to be mindful of when you're posting. It's easy to think you're sharing a photo with a few people. 75 So don't post anything online, selfie especially.

A. There are lots of selfie styles.
B. The rise of selfies has become universal.
C. Social media, to some extent, is the driving force of their selfie activity.
D. The desire to take, post and get “likes” on selfies goes back to a biological behavior.
E. But the whole world of social media is public and every individual can get access to it.
F. There are also people who will take selfies because they have nothing else better to do.
G. The leading factor is that people want to get attention from as many people as possible.

答案：

16. wrong 17. 3C56 18. system 19. special 20. Credit

21.C
【解析】考查倒装句。句意为：——我不会再相信他了。他很让我失望。——我也不再相信他了。neither+情态动词/助动词+主语的倒装结构表示“也不……”，故C项正确。

22.A
【解析】考查冠词的用法。句意:理解成千上万个新单词的一种非常有效的方法就是很好地掌握基本的构词法。most与不定冠词a连用,构成a most,相当于a very,意为"非常";gain a good knowledge of意为"好好掌握……的知识",此处为抽象名词具体化,为常用搭配。

 
23.D
【解析】考查情态动词。句意为：——那个女人照顾那两只白虎8年了。——天哪！她一定克服了很多困难。表示肯定的推测用must，再结合时间状语for 8 years可知，用must have done结构表示对过去发生的事情最有把握的猜测，意为“一定做过某事”，故D项正确。

 
24.B
【解析】考查非谓语动词。句意为：当课堂上被提问时，应该尽可能清楚地回答。逻辑主语one与ask之间是逻辑上的动宾关系，表示被动，且表示一般情况，所以用过去分词作状语，故B项正确。

 
25.C
【解析】由before you left可知,wish后的从句表示对过去所发生的事情的虚拟,故从句应用过去完成时。

 
26.D
【解析】考查替代词。句意为：Amy丢了钱。她的妈妈对此对不感到惊讶,因为她太粗心了。did so代替lost her money，故D项正确。

 
27.B
【解析】考查with的复合结构。句意为：由于有两个孩子正在附近的镇子里读中学，那对父母工作很努力。children与attend之间是逻辑上的主谓关系，表示主动，再由时间状语now可知，表示正在进行，故B项正确。

 
28.C
【解析】考查形容词词义辨析。句意为：星期日额外的课程给本来已经有很多作业的学生更多的压力。pressure意为“压力”时是不可数名词，所以排除A和D项，homework是不可数名词，many of 后面接可数名词，piles of意为“一大堆的”，后面可以接不可数名词，故C项正确。

 
29.A
【解析】考查固定表达。句意为：——你认为Jack应该受到责备么？——是的，在吃饭时他把面巾纸扔向客人是非常无礼的。be+形容词+of sb+to do表示“某人做某事是……的”，故A项正确。

 
30.C
【解析】考查名词性从句。句意为：前天我差点就没命了，一辆车以我认为是十分危险的速度在我身边疾驰而过。_____ was a dangerous speed作介词at的宾语，I thought是插入语，关系词在从句中作主语，故C项正确。

 
31.D
【解析】考查非谓语动词。第一空是对 him 进行补充说明, him 与 sit 构成主动关系,与seat构成被动关系,可用sitting或seated,with his attention 　　　on a book是"with+宾语+宾补"结构, his attention 与 fix 之间是动宾关系,故第二空用过去分词fixed。综上可知D项正确。

 
32.D
【解析】考查虚拟语气。句意为：——真可惜你错过了昨晚的晚会，它好极了。——我本来想去的，但是我要照顾生病的妈妈。would have done是对过去事情的假设，表示“本来会做”，故D项正确。

 
33.C
【解析】考查定语从句。句意:我们特别感谢数以千计的志愿者们,没有他们不知疲倦的工作,所有这些都不可能做到。volunteers与tireless work是所属关系,所以用关系代词whose,在从句中作定语。

 
34.B
【解析】考查时态。句意为：——打扰一下，你在听我说话么？——不好意思，我刚才正在想明天考试的事情。由句意可知，说话时第二个人的思路已经被第一个人的话语打断，因此此处强调刚才正在进行的动作，用过去进行时，故B项正确。

 
35.A
【解析】考查情态动词。句意为：当我们在同一个办公室工作的时候，我们常常一起喝咖啡。此处指的是过去经常性的动作，would=used to，表示“过去经常做某事”，故A项正确。

 
36．B
【解析】由第一段第一句可知，假日的早上"我"不用去上学， 而根据第一段最后一句可知,在这样一个特别的早上,"我"想早起,这说明"我"在假期的早上通常不会早起的，所以可推断，在假日，妈妈允许我晚一点儿起床。

48．A
【解析】这里要注意连词and所表示的递进关系，后面是停下来闲聊，只有"打招呼"才能吸引人过来聊天。

We took a 20-kilometer hike last Friday, and it has been one of the most unforgettable experiences since high school.
Early in the morning, we got together and set out on foot. All of us carried backpacks with water and food. At the beginning, we enjoyed the beautiful scenery and had a great time. Gradually we started to sweat a lot. Some of us became out of breath and some fell behind, but we encouraged each other to keep going. We kept at walking and walking. We almost made it to school when one of my classmates fell down. All of us ran up to help her, having no time attend to our tiredness. After another hour, we finally managed to walk back to school. We were so pleased and proud, cheering and hugging each other. We took photos to record the exciting moment.
What an unforgettable experience! It’s more than a hike. It’s a journey of hard work and challenge, in which we’ve learnt to be more determined and strong-minded.
