高三英语单项填空中等难度题查看答案及解析
The State Council declared Wednesday it would restart China's nuclear power program, ending the hiatus（中断）in nuclear construction since Japan's Fukushima nuclear disaster last year.
China has been the most courageous country in building nuclear power, with the largest number of plants currently under construction. Nuclear power is facing a tough time in developed countries. The Japanese public is demanding the closure of all the country's nuclear power plants. China is at the forefront of nuclear power development. But it has been forced into this position.
Rapid economic development coupled with improvements in people's life both demand more electricity. It is impossible to exploit fossil resources forever as the supply of coal, oil and natural gas is limited. China has no choice but to develop nuclear power.
China must be the safest user of nuclear power. It should become a leading country in developing nuclear power technologies and increasing the world's knowledge of nuclear power.
It needs to do at least two things. First, it needs to promote safety in nuclear power plants, based on the technologies of the West. The former Soviet Union, the US and Japan all had severe nuclear accidents, proving there are risks. China should try to remove these risks.
Second, China should establish effective communication mechanisms（机制）between the government, power plants and the public. It's wrong to think the government can control every aspect of nuclear power plant construction.
The opposition to nuclear power program in developed countries has prevented them from building new plants, but they already have many. These governments are reluctant to close these plants despite strong opposition, because they cannot find better substitutes.
Nuclear power only occupies 1.8 percent of China's current electricity grid（输电网）, much lower than the proportion in many developed countries. China's nuclear power plan should introduce the advantages of the technologies of other countries and also be creative in providing security. Its space technology is not the most advanced, but its launch safety measures have proven to be among the best.
China's high-profile high-speed railway development has drawn a lot of controversy, as will the active attitude towards developing nuclear power. But China cannot just copy what the developed countries have done. The development of nuclear power must be unique to China and it must be a ground-breaking success. But now, the real test lies ahead.
1.In the third paragraph the writer focuses on ______.
A. the reason why China is to develop nuclear power
B. the difficulty China has in developing nuclear power
C. the measures China will take to develop nuclear power
D. the benefits China will have by developing nuclear power
2.What attitude do people in developed countries have towards nuclear power program?
A. Supportive. B. Opposed. C. Indifferent. D. Objective.
3.. If the Chinese government is to develop nuclear power, it needs to ______.
A. copy exactly what the developed countries have done
B. depend entirely on domestic scientists and technologies
C. avoid people’s involvement in nuclear power plant construction
D. do everything in its power to guarantee safety in nuclear power plants
4.What is the future of China’s nuclear power program according to the text?
A. It will be unique but can hardly pass too many tests.
B. It will be full of controversy but carried out firmly.
C. It will be on a smooth way to a ground-breaking success.
D. It will receive much opposition from developed countries.

What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves – but man-made ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to copy this seemingly simple process.
The man-made leaf developed by Daniel Nocera and his partners at MIT can be seen as a special chip with catalysts (催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), which uses those two materials to produce electricity.
A man-made leaf is not a new idea. The first man-made leaf was invented in 1997 but was too expensive and changeable for practical use. The new leaf, on the contrary, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that a man-made leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera’s recent discovery of several powerful, new, inexpensive catalysts. These catalysts make the energy change inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the machine can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have enough pure water.
With the goal to “make each home its own power station” and “giving energy to the poor”, scientists believe that the new machine could be widely used in developing countries, especially in India and rural China.
1.What will give power to our house in the future, according to MIT?
A. Man-made leaves. B. Nuclear.
C. Solar power. D. Wind.
2.Which of the following orders correctly shows how the man-made leaf is used to produce electricity?
a. man-made leaves split water into hydrogen and oxygen
b. the hydrogen and oxygen gases are stored in a fuel cell
c. the man-made leaves are put in water
d. the fuel cell uses hydrogen and oxygen to produce electricity
A. cbad. B. bcad.
C. cabd. D. cadb.
3.What does the underlined “stable” in the 4th paragraph mean?
A. Secure. B. Powerful.
C. Unnatural. D. Unchangeable.
4.The aim of the scientists at MIT in developing the new man-made leaves is to .
A. build up more power stations in the world
B. provide cheaper energy for developing countries
C. offer people in developing countries access to pure water
D. gain a deeper understanding of the photosynthesis process

What will power your house in the future? Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves –but artificial ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip (硅片) with catalysts (催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), which uses those two materials to produce electricity, located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card, scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Docera at a conference of the American Chemical Society.
An artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf, by contrast, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that an artificial leaf prorotype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera’s recent discovery of several powerful new, inexpensive catalysts. These catalysts make the energy transformation (转换) inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the device can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have access to pure water.

A. cbad B. cabd C. bcad D. cadb
2.Which of the following statements about new artificial leaves is TRUE according to the article?
A. They are inexpensive but unstable.
B. They are as efficient at carrying out photosynthesis as natural leaves.
C. They can work only in pure water.
D. They need several catalysts to help them work efficiently.
3.The aim of the scientists at MIT in developing the new artificial leaves is to ________ .
A. build-up more power stations in the world
B. provide cheaper energy for developing countries
C. offer people in developing countries access to pure water
