Brace yourself for impact(撞击力)．As soon as you"re aware that you"re going off the road and into a body of water，adopt a brace position.The impact could set off the airbag system in your vehicle，so you should place both hands on the steering wheel in the “ten and two” position.
Undo your seatbelt.__小题2:__ Unbuckle the children，starting with the oldest first.Forget the cellphone call.Your car isn"t going to wait for you to make the call.
_小题3:_ Leave the door alone at this stage and concentrate on the window.A car"s electrical system should work for up to three minutes in water，so try the method of opening it electronically first.Many people don"t think about the window as an escape option either because of panic or misinformation about doors and sinking.
Break the window.If you aren"t able to open the window，or it only opens halfway，you"ll need to break it with an object or your foot.It may feel counterintuitive(有悖常理的) to let water into the car._小题4:__
Escape when the car has equalized.If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced，you must move quickly and effectively to ensure your survival._小题5:__ While there is still air in the car，take slow，deep breaths and focus on what you"re doing.
| A．Open the window as soon as you hit the water. |
| B．Surviving a sinking car is not as difficult as you think. |
| C．It takes 60 to 120 seconds for a car to fill up with water usually. |
| D．Such accidents are particularly dangerous to the risk of drowning. |
F．This is the first thing to attend to，yet it often gets forgotten in the panic.
G．But the sooner the window is open，the sooner you can escape directly through it.
1．______ 2.______ 3.______ 4.______ 5.______
答案
小题1:D
小题2:F
小题3:A
小题4:G
小题5:C
解析
小题1:D 空格前的“an accident in which your vehicle is thrown into the water”与D项中的“Such accidents”对应，而空格处句子与空格后一句为转折关系，故选择D项。
小题2:F 空格前句“Undo your seatbelt.”与F项中的“This is the first thing to attend to”对应，故选择F项。
小题3:A 根据本段中的“concentrate on the window”和“Many people don"t think about the window as an escape option either because of panic...”可知选择A项。
小题4:G 首先空格前句与空格处为转折关系，本段仍旧围绕“window”进行阐述，G项所表达的意思为打开窗户逃生，与本段主旨一致，故选择G项。
小题5:C 空格前的“car cabin has been filled with water”与C项中的“fill up with water”对应，而C项所表达的意思也与空格后的“While there is still air in the car”相关联，故此题选择C项。

举一反三
After Fukushima, Germany decided to switch off all its nuclear plants by 2022. __小题1:__ In fact, almost 80% of France"s electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”
Nuclear supporters claim nuclear power can help the environment. 小题2:__ So, pronuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain"s chief scientific adviser(John Beddington) supports this view.
Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they"re expensive; and right now, they require a lot of investment. _小题3:__ So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills.
小题4:__ For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several highprofile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands of people.
The nuclear energy issue is very complex. _小题5:_ As a Japanese commentator recently said, “It"s been a bad year for the ‘nuclear village’， but I don"t think they"re down and out yet.” The battle continues.
| A．And it doesn"t look like it"ll be resolved anytime soon. |
| B．The main argument against nuclear energy is that it isn"t safe. |
| C．Nuclear power could only end the world instead of saving it! |
| D．Many people believe that they will benefit from the unclear energy. |
F．But France and the United States remain loyal supporters of atomic energy.
G．This higher cost of using “green energy” is usually passed onto the consumer.

_小题2:_ It should become smaller, safer, and more moneysaving, and should not be powered by the petrol engine. The car of the future should be far more pollutionfree than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban traffic jam. _小题3:_
When the auto enters the freeway system, a retractable arm, which can be moved inwards or backwards, will drop from the auto and touch a rail that is similar to the subway trains electrically powered from the system, and control of the vehicle will pass to a central computer. 小题4:_
The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the freeway. _小题5:_ It is guessed that an automated freeway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a presentday freeway.
| A．Other authorities, however, think the auto is here to stay. |
| B．The computer will then monitor all of the car"s movements. |
| C．One proposed solution to this problem is the automated freeway system. |
| D．Experts have different views on what role autos will play in the near future. |
F．Drivers in the freeway system can sit back and do nothing but control the direction.
G．The driver will then be free to relax and wait for the sound speaker that will warn him of his coming exit.

To investigate when cockroaches(蟑螂) learn best, researchers at Vanderbill University tested the insects for which odor(peppermint 薄荷 or vanilla 香草) they preferred. Most cockroaches preferred the smell of vanilla to that of peppermint at all times. __小题2:__ Therefore, the scientists trained the cockroaches to prefer the peppermint smell by rewarding the insects with a taste of sugar water when they approached a peppermint smell. _小题3:__
When the cockroaches were trained at night, they remembered the new associations(peppermint＝sugar water; vanilla＝salt water) for up to 48 hours. However, if the cockroaches were trained in the morning, they quickly forgot which smell went with which water. __小题4:_
So, cockroaches learn better at night than they do in the morning. _小题5:_ Because of this, it is likely that information they gather at night will be more useful to them. These experiments provide some clues about the interactions between body rhythms, learning and memory.
| A．When these insects moved toward a vanilla smell, on the other hand, they were punished with a taste of salt. |
| B．This result thus shows that the time when they were trained decided the effect of their learning. |
| C．They are often more active and tend to search for food during the night. |
| D．They were also found to like sugar water, but not salt water. |
F．But they prefer warm conditions found within buildings.
G．Pest species adapt easily to their environment.
| A．struck | B．approached |
| C．accessed | D．occurred |
| A．gave out | B．gave away |
| C．gave in | D．gave up |
