【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
Eyesight plays a very important role in our daily life. Every waking moment，the eyes are working to see the world around us. Over forty per cent of Americans worry about losing eyesight，but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：
Schedule yearly exams Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.
Protect against UV rays(紫外线)．Longterm stay in the sun creates risk to your eyes. No matter what the season is，it's extremely important to wear sunglasses. Give your eyes a break. Twothirds of Americans spend up to seven hours a day using computers or other digital products.
Experts recommend that people practise the 20/20/20 rule：every 20 minutes，take a 20second break and look at something 20 feet away.
As part of a healthy diet，eat more fruits and vegetables each day. Vitamins(维生素) C and E help protect eyesight and promote eye health.
Practise safe wear and care of contact lenses(隐形眼镜)．Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses，many are breaking the rules and putting their eyesight at risk. Otherwise，you may have problems such as red eyes，pain in the eyes，or a more serious condition.
A．This frequent eye activity increases the risk for eye tiredness
B. Eye care should begin early in life.
C．Eat your greens.
D．They can properly protect your eyes.
E．Stay in good shape by taking more vitamins.
F．Parents usually don't care about their own eyesight.
G．Always follow the doctor's advice for appropriate wear.
【答案】B；D；A；C；G
【解析】本文是一篇议论文，介绍了五个建议可以让我们终身享有健康的视力
(1)考查句意理解和上下文串联。根据空后“Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check.”医生建议父母到6到12个月大的孩子去医院做视力检查，可知：保护视力应该很早就开始，所以答案是B。
(2)考查句意理解和上下文串联。根据空前“No matter what the season is, it's extremely important to wear sunglasses.”不管什么季节，戴太阳镜都是非常重要的，可知：它们可以适当的保护你的眼睛，所以答案是D。
(3)考查句意理解和上下文串联。根据空前“Two-thirds of Americans spend up to seven hours a day using computers or other digital products.”三分之二的美国人每天花7个小时使用电脑和其他数字产品，可知：这个频繁的视力活动会增加眼睛疲劳的危险，所以答案是A。
(4)考查句意理解和上下文串联。根据空后“As part of a healthy diet, eat more fruits and vegetables each day.”作为健康饮食，每天要多吃蔬菜和水果，可知：多吃绿色的食品，所以答案是C。
(5)考查句意理解和上下文串联。根据空前“While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk.”有人听从佩戴隐形眼镜的医学建议，而有人忽视了这些规定让他们的视力有危险，可知：佩戴眼镜要听从医生的建议，所以答案是G。

【题目】阅读下列短文，从每题所给的 A、B、C 和 D 四个选项中，选出最佳选项。C
The main aim is a fully autonomous car that gets rid of the cause of most accidents: the driver, Hodgson points out, ＂For the sake of safety, the faster you can remove humans, the better, even if there are unfortunately a few accidents from new causes. It's a question of balancing the number injured or killed by autonomous vehicles with the people whose lives are potentially saved.＂
It's a theme that Elon Musk, head of electric car company Tesla Motors, has long supported. His company is determined to be the first to deliver a fully autonomous vehicle to consumers. Last year, Musk announced that Tesla's 2017 goal was ＂to do a demonstration ( 示 范 ) drive of full autonomy all the way from LA to New York...and have the car park itself.＂
However, even Tesla admits that there are problems to overcome — the software needs further confirmation and the appropriate regulatory (监管的) approval needs to be in place. Indeed, recent crashes of Tesla vehicles and Google cars confirm that the software isn't ready yet.
The UK government appears determined to encourage the development of autonomous vehicles. It's supporting four city trials, publishing the Modern Transport Bill to reduce red tape around their introduction and adapting the legal system to take into account issues such as insurance liability when a human isn't in control of a vehicle.
The insurance industry is similarly keen to promote increasing autonomy in cars. As the Association of British Insurers (ABI) points out: ＂More than 90 per cent of road accidents are attributed to human errors.＂ This costs motor insurers a surprising 20 per day in claims.
（1）In Hodgson's opinion, what is the problem with the driverless cars?
A.Whether it is true that the faster you can remove humans, the better.
B.Who can explain why there are still a few accidents by driverless cars.
C.How to deal with the new causes of accidents resulting from driverless cars.
D.Whether to balance the number injured or killed with the people whose lives may be saved.
（2）Why is the insurance industry in favor of driverless cars?
A.Because they can make their insurers save money in claim.
B.Because it is drivers' errors that lead to over 90% road accidents.
C.Because human errors cost motor insurers a surprising 20 per day in claims.
D.Because motor insurers believe driverless cars will never cause any road accidents.
（3）Which is the best title of the passage?
A.The advantages of driverless cars.
B.The disadvantages of driverless cars.
C.Driverless cars in future.
D.The development of driverless cars.

【题目】阅读理解
When another old cave is discovered in the south of France, it is not usually news. Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them. However, when the Lascaux cave complex was discovered in 1940, the world was amazed. Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats. Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.
Early artists drawing these animals achieved a monumental and difficult task. They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or going on hands and knees into narrow passages in the Lascaux complex.
Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside.
Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are hardly recognizable. To prevent further damage, the site was closed to tourists in 1963, 23 years after it was discovered.
（1）Which title best summarizes the main idea of the passage?
A.Wild Animals in Art
B.Hidden Prehistoric Paintings
C.Exploring Caves Respectfully
D.Determining the Age of French Caves
（2）What does the underlined phrase “pays heed to” in paragraph 2 probably means?
A.discovers
B.watches
C.notices
D.buys
（3）Why was painting inside the Lascaux complex a difficult task?
A.It was completely dark inside.
B.The caves were full of wild animals.
C.Painting materials were hard to find.
D.Many painting spaces were difficult to reach.
（4）According to the passage, all of the following have caused damage to the paintings EXCEPT _______.
A.temperature changes
B.air movement
C.water
D.light
