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.
1.______ 2.______ 3.______ 4.______ 5.______
答案
小题1:F
小题2:E
小题3:G
小题4:B
小题5:A
解析
小题1:F 根据下文可知,法国和美国是核能的忠实支持者,与上句德国的做法相反,所以选F项作为过渡。
小题2:E 本段第一句“...nuclear power can help the environment”与E项中的“nuclear power doesn"t create greenhouse gases...”相呼应。本段主要讲述核能不会产生温室气体,有利于保护环境。
小题3:G 根据上下句内容可知,空格处表达的意思为“使用‘绿色能源’的高额费用通常转嫁到消费者身上”。G项符合语境。
小题4:B 本段主要讨论了核能的不安全性,所以本句“反对核能的主要观点是因为它不安全”符合题意。故选B项。
小题5:A 根据下文中的“It"s been a bad year for the‘nuclear village’,but I don"t think they"re down and out yet”,可知问题并没有解决。所以本句为上句“核能源问题是复杂的”的递进句,“而且核能问题似乎并不会马上得到解决”。故选A项。

举一反三
_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.
1.______ 2.______ 3.______ 4.______ 5.______
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 |
A.picked out | B.ruled out |
C.brought out | D.taken out |
