According to official statistics released by the Chinese government, China is expected to run out of water around the year 2030. In its directive on water use, the State Council (国务院) has stated, “Taking into full account water-saving, by 2030 our country’s water use will reach or approach the total volume of exploitable water resources (可利用的水资源总量), and the drought-fighting situation will be increasingly serious.” Such statements are certainly serious, and every man, woman and child in China must consider the situation and how it relates to their lives.

So, will China run out of water completely? The news is not all bad. Although there are serious concerns, there are some reasons to be hopeful. One of the simplest is just to consider that China has had a long history of water problems. From flooding to drought, balancing water needs has always been an issue in China; it is something that many public projects are already addressing. Some of these projects need time before their long-term value can be properly seen, but there is reason to hope that they will prove useful.

Another reason for hope lies in what seems at first to be a terrible fact: nearly 70% of China’s water is so contaminated that it is not only unsuitable for drinking but is also not useful for individual purposes. How can this be good news? Well, in recent years, the terrible situation has motivated the government and the public to become more and more committed to cleaning up these contaminated sources. Several projects have already been successful in partially cleaning these water sources. As this commitment increases, more and more of China’s water is being cleaned and made available for use.

Finally, the international community, particularly NGOs (Non Government Organizations) and the corporate community, have begun to focus on ways to help China stretch its limited water resources. Several business and NGOs are already studying the issue and investing in solutions.

It is certainly important for everyone in China to understand the situation and to take part in conserving water. Thankfully, however, the situation is not hopeless. Through the cooperation of the government, the people, NGOs and business, China can continue to find the water it needs.

72. What does the first paragraph tell us?

A. China is seriously short of water now.’

B. We still have enough water for drink and use.

C. China will be faced with serious water shortage in two decades.

D. We needn’t consider the situation for the moment.

73. Which of the following reasons to be hopeful is not mentioned?

A. Many in the international and corporate community have begun to help China.

B. China has dealt with many water problems.

C. The government and the public are becoming more and more committed to cleaning up the contaminated sources.

D. The Chinese have enough confidence and courage to overcome the difficulty.

74. Which of the following can replace the underlined word contaminated in Paragraph 3?

A. cleaned           B. wasted           C. polluted            D. purified

75. Which of the following statements is TRUE according to this passage?

A. The international community and the corporate community have begun to help China develop it limited water resources.

B. All China’s water is so contaminated that it is unsuitable for both drinking and industrial purposes.

C. Several business and NGOs had already studied the issue and invested in solutions.

D. There is no hope for China to find the water it needs.

  A 63-year-old man who hasn't slept for more than two decades has been told there is nothing wrong with him by doctors.

  Ukrainian Fyodor Nesterchuk from the town of Kamen-Kashirsky said the last time he managed to sleep was more than two decades ago.

  "I can't remember the exact date and I don't know why it started, but all of a sudden I found it more and more difficult to nod off until eventually I was awake the entire night.I used to read boring scientific magazines in the hope that they would send me to sleep.But as soon as I felt my eyes getting closed and put the magazine down, I would find myself wide awake again.I thought it would just be a period of time but it has gone on for over two decades now and I've simply had to get used to it.Now when everyone else sleeps I get stuck into a good book," said Nesterchuk.

  All attempts by doctors to put him to sleep have failed.Local doctor Fyodor Koshel who has examined Nesterchuk extensively and has been unable to make him fall asleep, said he has no idea of the cause of the insomnia and added medically there is nothing wrong with him."We have no idea why he can't sleep, maybe it's the result of a past illness.But in terms of medical science, he's not in any pain and so there isn't anything actually wrong with him," said Dr Koshel.

Read the following four passages.Each passage is followed by several questions or unfinished statements.For each of them there are 4 choices marked A, B, C and D.Choose the one that fits best according to the information given in the passage.

  Batteries can power anything from small sensors to large systems.While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves.University of Missouri(MU)researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

  “To provide enough power, we need certain methods with energy density(密度),” said Jae kwon, assistant professor of electrical and computer engineering at MU.“The radioisotope(放射性同位素)battery can provide power density that is much higher than chemical batteries.”

  Kwon and his research team have been working on building a small nuclear battery, recently the size and thickness of a penny, intended to power various micro/nano-electromechanical systems(M/NEWS).Although nuclear batteries can cause concerns, Kwon said they are safe.

  “People hear the word ‘nuclear’ and think of something very dangerous,” he said.“However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

  His new idea is not only in the battery's size, but also in its semiconductor(半导体).Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.

  “The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶格结构)of the solid semiconductor,” Kwon said.“By using a liquid semiconductor, we believe we can minimize that problem.”

  Together with J.David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery.In the future, they hope to increase the battery's power, shrink its size and try with various other materials.Kwon said that the battery could be thinner than the thickness of human hair.

(1)

[  ]

A.

He teaches chemistry at MU.

B.

[  ]

A.

to show chemical batteries are widely applied

B.

to indicate nuclear batteries can be safely used

C.

to describe a nuclear-powered system

D.

to introduce various energy sources.

(3)
