News reports warn us that the smog is expected to stay with us for a couple of months. Air quality is 10 times worse than the World Health Organization’s recommended levels. You may think that there is nothing you can do about the air you breathe【1】

Wear an N95 mask.

Surgical masks won’t do, my friends. You need a proper N95 mask. 【2】The purpose is to filter out the little particles (顆粒) in the air that can be very unhealthy if breathed in. It’s not attractive, but your health is more important than looking attractive.

Drink lots of water and stay hydrated.

Hot temperature and high humidity are often connected with high smog levels. This makes it important to stay in the shade and drink lots of water to stay hydrated, especially before, during, and after exercise. 【3】

Stay indoors.

If possible, stay indoors. While you might want to visit your favourite open-air hawker stall (小販攤檔), now it’s not the time to do so. 【4】 Better still, for those at work, pack your own lunch. What’s more important, avoid exercise outdoors, especially from mid-morning to early evening, when smog levels are higher.

【5】.

Often neighbors or family members smoke in the hallways or just outside of apartment buildings, which makes the air much worse. And this air still comes into the apartments. So, keep the windows closed and use air purifiers to protect your home.

When your city’s smog gets bad, now you have the tips to keep on trucking. Best of luck.

A. Protect your home.

B. Keep the doors open.

C. If you want to go out, go to malls, and eat in enclosed spaces.

D. Consider exercising indoors in a smoke-free, air-conditioned environment.

E. However, there are easy ways to protect yourself against smog and air pollution.

F. Besides, water will not only quench your thirst, but help clear your breathing passages.

G. Its straps should be securely fastened behind your head, to hold the mask against your face.

【答案】

【1】E

【2】G

【3】F

【4】C

【5】A

【解析】

試題分析：本文屬于說明文閱讀，介紹了在現(xiàn)在空氣污染情況較為嚴(yán)重的情況下，我們可以采取的四種方法讓自己少吸入被污染的空氣。

【1】E 根據(jù)橫線前句You may think that there is nothing you can do about the air you breathe.也許我們會(huì)認(rèn)為對于我們吸入的空氣質(zhì)量我們沒有辦法控制。在文章下面提出了四個(gè)改變我們吸入空氣的建議。故E項(xiàng)“However, there are easy ways to protect yourself against smog and air pollution.有一些很容易的方法保護(hù)我們不受霧霾和空氣污染的傷害”屬于上下文的過渡句。符合上下文串聯(lián)。

【2】G 根據(jù)橫線前句You need a proper N95 mask.人們需要N95型號的口罩。且橫線后句說明這一口罩的作用。所以橫線句應(yīng)該說明這一型號口罩的使用方法。故G項(xiàng)“Its straps should be securely fastened behind your head, to hold the mask against your face”符合上下文串聯(lián)。

【3】F 本段標(biāo)題“Drink lots of water and stay hydrated”建議我們多喝水保濕。根據(jù)橫線前句This makes it important to stay in the shade and drink lots of water to stay hydrated, especially before, during, and after exercise.高溫高濕要求我們在鍛煉前、中、后都要多喝水，那么本句應(yīng)該說明水的作用。F項(xiàng)“Besides, water will not only quench your thirst, but help clear your breathing passages.”恰好在說明喝水的重要作用。故F項(xiàng)符合上下文串聯(lián)。

【4】C 本題標(biāo)題為“Stay indoors”建議我們待在室內(nèi)，盡量不外出。所以C項(xiàng)“If you want to go out, go to malls, and eat in enclosed spaces.如果你想外出，就都購物中心在相對封閉的空間里吃飯”符合本段中心思想。

【5】A 根據(jù)本段最后一句“So, keep the windows closed and use air purifiers to protect your home.”可知當(dāng)人們在室外抽煙的時(shí)候，我們最好關(guān)閉門窗并使用空氣凈化器來保護(hù)我們的家�？芍狝項(xiàng)“Protect your home”符合上下文串聯(lián)。

【題目】Almost one in five drivers had dozed off behind the wheel, a shocking news report had showed. Of those who were dozing off, 29% have done so with their cars speeding at 70 miles per hour. The report also found a quarter of men have fallen asleep while driving, making it almost twice as many as women.

The Safety on Wheel Report, by Post Office Insurance, also looked at how often tiredness or a lack of concentration caused accidents. Three in ten drivers have experienced an accident, from passing a walker crossing to hitting another vehicle, because of a lack of concentration. Meanwhile, almost half (49%) of UK drivers have driven when they do not concentrate.

Paul Havenhand, head of insurance at Post Office, said, “ When tiredness strikes, drivers should avoid the roads.” There is no measurement for tired driving, unlike driving under the influence of alcohol, yet it could result in an equally dangerous accident.

Drivers are advised to take a 15-minute break from driving every two hours. However, a third (36%) are so eager to reach their destination that they will ignore feelings of tiredness. What’s more, almost one in five (18%) will drive for longer than four hours without a break, while 6% carry on for up to 6 hours. Just over a quarter (27%) choose a quick stop to buy a cup of coffee, which is a very popular way for drivers to get rid of tiredness, and only 17% stop to have a rest until they feel energetic again. Mr. Havenhand added, “Drivers should plan ahead and rest before starting a long journey; besides, they can take regular breaks to recharge their batteries while on road; in some cases, if they do feel too tired to concentrate on the roads, they could consider an alternative means of transport.”

【1】Which suggestion is NOT put forward by Mr. Havenhand?

A. Preparing well for a long journey and taking a complete rest before it.

B. Having breaks regularly in order to feel refreshed.

C Choosing another method of transport instead.

D. Choosing a quick stop to grab something to eat.

【2】What does the underlined phrase “recharging their batteries” in the last paragraph mean?

A. Put a new supply of electricity into their batteries.

B. Get back their energy by resting for a while

C. Accuse them of stealing batteries

D. Pay twice more money for their batteries

【3】It is implied in the last paragraph that for drivers the most popular cure for tiredness is _____.

A. drinking coffee

B. talking with others

C. ignoring feelings of tiredness

D. singing songs

【4】What’s the purpose of the writer in writing this passage?

A. To warn people of the danger of tired driving

B. To tell people to be careful when walking on the street

C. To inform people of the importance of a good rest

D. To introduce some dangers while driving on the roads

【題目】The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’

But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

【1】Walking on water hasn’t become a reality mainly because humans______.

A. are not interested in it

B. have biological limitations

C. have not invented proper tools

D. are afraid to make an attempt

【2】What do we know about Basilicus basilicus from the passage?

A. It is light enough to walk on water.

B. Its huge feet enable it to stay above water.

C. It can run across water at a certain speed.

D. Its unique skin keeps it from getting wet in water.

【3】What is the function of the cornflour according to the passage?

A. To create a thick liquid.

B. To turn the water into solid.

C. To help the liquid behave normally.

D. To enable the water to move rapidly.

【4】What is the author’s attitude toward the idea of humans’ walking on water?

A. It is risky but beneficial.

B. It is interesting and worth trying.

C. It is crazy and cannot become a reality.

D. It is impractical though theoretically possible.

【題目】“Clothes-swapping” has become an increasing popular activity for women in the United States. The women can give away unwanted clothing at a clothes swap event and get something different in return.

Recently about 300 women went to a clothes swap at a high school in Springfield, Virginia. It was the largest crowd ever for the area’s popular clothing-swap group.

Daphne Steinberg was having a very good day. “For anyone who knows Ann Taylor LOFT，Ann Taylor is a really nice women’s designer and I’ll totally wear this to work. So I love that, I love that I can equip myself for work, have a good time in doing it, not totally bankrupt myself. ”

Kim Pratt organized the clothing-swapping event in Springfield. She also organized a money-raising activity for the high school’s debate team. It’s one of several ways that her group gives to charitable causes. Another is by donating all of the “un-swapped” clothing to shelters for victims of domestic violence.

“I started doing this myself four years ago, and we’ve been doing it for four years, getting bigger and bigger each time we have a swap.”

She used the social media website meetup. com to help publicize the events. The website has helped her group grow from 30 members to 1,300. Ms Pratt says most of the members respect clothing swap rules. But she says competition for desirable fashion can be strong.

“We have to tell people sometimes not to hover (徘徊) over the new people coming in with their clothing. As they put it out，some people tend to grab (搶奪) the stuff right out of their hands and it becomes like a free-for-all. We try to avoid that as much as possible.”

【1】We can learn from what Daphne Steinberg said that .

A. she saved much more money than she had expected

B. it was the first time she had been to a clothes swap

C. the clothes swap was the largest ever in the area

D. she got some nice clothes at the clothes swap

【2】What’s Paragraph 4 mainly about?

A. What Kim Pratt did to help others in need

B. What Kim Pratt did with the un-swapped clothing.

C. How Kim Pratt helped a high school’s debate team.

D. How Kim Pratt started the clothing-swapping event.

【3】The underlined word “publicize” in Paragraph 6 probably means “ ”.

A. observe B. manage

C. advertise D. prove

【4】What can be inferred from the last paragraph?

A. Clothes-swapping is becoming increasingly popular with women.

B. Improper behavior at clothes swaps needs to be controlled.

C. More clothing swapping events need to be organized

D. Clothes swaps often go out of control in the end.

【題目】When we can see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we come to see how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing, reading and sewing（縫紉）, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted（遠(yuǎn)視的）suffer from just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.

Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts（白內(nèi)障）. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

When night falls, colors become fainter to the eye and finally disappear. After your eyes have grown used to the dark, you can see better if you use the sides of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn you head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they cannot see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive(敏感的) in daylight, is not as sensitive as the sides of the eyes after dark.

【1】We don’t know that our eyes are of great importance until _____.

A. we think about our eyes B. we cannot see clearly

C. we wear glasses D. we have to do much reading

【2】According to the passage, a _____ is more likely to be nearsighted.

A. tailor B. doctor

C. guard D. painter

【3】Those who suffer from cataracts _____.

A. will become blind B. cannot be cured（治愈）

C. may be cured D. must move to other places

【4】People who are farsighted _____.

A. cannot do a lot of close work without glasses

B. can only see things that are very close to their eyes

C. have difficulty reading a book if they hold it at arm’s length

D. have the same problem as the nearsighted people

【5】To see a small thing at night, it is better to look ______.

A. with wide open eyes

B. with half- shut or narrowed eyes

C. straight at it

D. in a slightly different direction

【題目】閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)

Tips for Cycle Trips

Cycling has many advantages as a form of travel, as it is the fastest way to travel by human Power, and slow enough to allow the type of local involvement that is impossible with powered travel．Cycle travel is a cheap form of transportation．

Distance

On level terrain（地形）,without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day．Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit．For many,80-100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities．

Geography

The gradient（坡度）of the trip will reduce your range．A basic rule is that for every 100 metres of altitude you climb, you should add an extra 15 minutes to your journey time．In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill．A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass．However, it is worth bearing in mind that the most scenic routes often come from hilly terrain．

Eat

Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food. On long trips away from major towns-there may be little quality food available, so be prepared to live on candy bars, prepared meat products and the like if the need arises.

Sleep

While you can take a tent with you, many hotels and especially campsites can accommodate cyclists. However, there are also some hotels that may be less used to accommodating cyclists.If you are exploring an unfamiliar world, asking about the accommodation spares you the search for a new place to stay after a long exhausting day of travel.

【1】Which distance does the author suggest to ordinary cyclists a day?

A．50km. B．90km.

C．130km. D．250km.

【2】Form the passage, we can learn that_____________.

A．high quality food is easy to get on long trips

B．hotels seldom provide accommodation for cyclists

C．cycling over a mountain is challenging but worthy

D．it takes cyclists 15 minutes to climb 100m of altitude

【3】We can probably read this passage in___________.

A．a(chǎn) geography book B．a(chǎn) research report

C．a(chǎn) science fiction D．a(chǎn) travel magazine

【題目】Recently some American scientists have given a useful piece of advice to people in industrialized countries.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago.【1】

The scientists say that human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this has led to new kinds of sicknesses.【2】They are called“diseases of civilization”．Many cancers and diseases of the blood system are examples of such diseases.

The scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none.【3】However, a change in food is one of the main differences between life in ancient times and that today.

Stone Age people hunted wild animals for their meat, which had much less fat than domestic (馴養(yǎng)的) ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products, and they made very little use of grains. 【4】 We eat six times more salt than our ancestors and we eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白質(zhì)) and much less vitamin C.

【5】But the scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fat, salty and sweet food.

A. Stone Age people lived a simple life without any meat.

B. But today, we enjoy eating a lot of these.

C. In that case, they would live a much healthier life.

D. Ancient people also got lots of physical exercise.

E. These new sicknesses were not known in ancient times.

F. People today probably don't want to live like our ancestors.

G. Modern people used to suffer from“diseases of civilization”．
