C
"Reduce, reuse and recycle, this familiar environmentalist slogan tells us how to reduce the amount of rubbish that ends up in landfills and waterways.
The concept is being used to deal with one possibly dangerous form of waste –--- electronic junk (電子垃圾), such as old computers, cell-phones, and televisions. But this process for managing e-waste may be used in an unscrupulous（不擇手段的） way more often than not used, a recent report suggests.
“A lot of these materials are being sent to developing nations under the excuse of reuse –--- to bridge the digital divide,” said Richard Gutierrez, a policy researcher.
One of the problems is that no one proves whether these old machines work before they hit the seaways. Because of this, the report says, e-waste is a growing problem in Lagos, Nigeria, and elsewhere in the developing world. Much of the waste ends up being thrown away along rivers and roads. Often it’s picked apart by poor people, who may face dangerous exposure to poisonous chemicals in the equipment.
Businessmen also pay workers a little money to get back materials such as gold and copper. This low-tech recovery process could expose workers and the local environment to many dangerous materials used to build electronics. According to Gutierrez, this shadow economy exists because the excuse of recycling and reusing electronics gives businessmen “a green passport” to ship waste around the globe. “Developing nations must take upon some of the responsibility themselves,” Gutierrez said. But, he added, “A greater portion of this responsibility should fall on the exporting state.”
China, for example, has become a dumping（傾倒，堆放） place for large amounts of e-waste. The nation is beginning to take action to stop the flow of dangerous materials across its borders. The Chinese government, after many years of denial（否認(rèn)）, is finally beginning to take the lead.
70．What does the fourth paragraph mainly discuss?
A. Old computers and TVs still work before they are sent abroad.
B. Poor people break up e-waste to collect some valuable materials.
C. A lot of e-waste is dumped in developing countries.
D. The problem of e-waste is growing in developing countries.
71．From what Gutierrez said we can learn that ________.
A. exporting countries should mainly be responsible for this problem.
B. neither rich nor poor countries should be blamed for this problem
C. developing countries should be responsible for this problem
D. poor countries should be blamed for this problem
72．It can be inferred from the last paragraph that _______.
A. China has hidden a large amount of e-waste in many secret places
B. China has greatly changed the idea about the problem of e-waste
C. China has prevented poisonous materials from entering China for a long time
D. China is falling behind other countries in dealing with e-waste
73．The passage mainly tells us that _______.
A. developing countries are facing serious environmental problems
B. e-waste is a growing problem in developed countries
C. e-waste is sent to developing countries under the excuse of reuse
D. developing countries are making full use of e-waste

There is an English saying:“ laughter is the best medicine.” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health. 

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter had similar effects to physical exercise. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial .

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which  diminish  both stress and pain .

As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

Doctors have proved the following EXCEPT that   ____   .

A. smiling does good to health 

B. laughter can be tolerated

C. there is a way to reduce pain 

D. laughter can work the muscles in the feet 

.The main idea of the passage is          .

A. laughter and physical exercise have similar effects on the human body 

B. smile can produce the same effects as laughter 

C. pain can be reduced by laughter 

D. laughter is the best medicine 

The students who  ___  tolerated the pain for the longest time .

A .listened to different radio programs

B .slept in the room 

C. don’t have stress of pain 

D .listened to a funny program

The underlined word “diminish” is similar to   _____     .

A. test    B .stop     C. reduce    D. find 

Doctors hold laughter clinics _________. 

A .to give better condition to their patients 

B .in order to improve patients’ health 

C .to make patients smile   

D. to prove smile and laughter have the same effect

E

       All areas of the world face a nurses shortage. But the shortage is most severe in developing countries. Many of their nurses move to the more developed nations for better pay, better working conditions and better chances for career development. For example, nearly 2,000 nurses left the Caribbean between 2002 and 2006.

       The Caribbean nations currently have about 1 nurse for every 1,000 people. The ratio(比例) of nurses to population is about 10 times higher in the United States and countries in the European Union(EU). Now, more than 21,000 nurses who trained in the Caribbean are working in the United States, Canada and Britain.

       Gaetan Lafortune is an official of the Organization for Economic Cooperation and Development(O.E.C.D) in Paris. He says the nurses shortage also affects industrialized countries. He says, “There is concern in most O.E.C.D.countries that the number of nurses is too small to meet the demand. And what is more worrying is that their concern is sort of growing.” Mr Lafortune says a large number of nurses are expected to retire within the next 10 years. At the same time, the health care needs of aging populations are expected to grow, intensifying the shortage of nurses.

       Gaetan Lafortune said, “In the U.S., for instance, some researchers have found that there may be a shortage of close to a million nurses by 2020.” The United States is 1 of the 21 countries in the O.C.E.D. Gaetan Lafortune says in the recent years many of the countries increased their efforts to hire foreign nurses. As a result of that, O.E.C.D. countries were mainly exporting their shortage problem to countries that may have an even greater need for these nurses.

What will be the main causes of the global nurses shortage in the next 10 years?

       a. The demand for nurses will decrease.                    

b. Many nurses will be too old to work.

       c. Many rich countries will hire more foreign nurses. 

d. Nurses are often looked down upon.

       e. Aging populations will increase rapidly

       A. a and b             B. b and c              C. b and e              D. c and d

The underlined word “intensify” in para. 3 means “________”.

       A. strengthen         B. neglect            C. reduce               D. cause

We know from this text that America and the EU countries ______.

       A. refuse to offer equal pay to foreign nurses

       B. have at least one nurse out of 100 people

       C. don’t like to train nurses of their own countries

       D. have more serious nursing problems than the Caribbean nations

What does the text mainly tell us?

       A. Nursing is no longer a worthwhile profession in most countries.

       B. The different attitudes towards nursing in different countries.

       C. Nurses shortage will result in serious consequences.

       D. The health care industry needs more nurses.
