1、MBA(英语)阅读理解练习试卷 1 及答案与解析一、Section III Reading ComprehensionDirections: Read the following four passages. Answer the questions below each passage by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.0 Lead deposits, which accumulated in soil and snow during the 1960s and 70s, were primarily
2、the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly. A study published recently in the journal Nature shows that air-borne
3、leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for S
4、cientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining. In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of Europea
5、n, Asian and Canadian gasolines and thus enabled scientists to differentiate the lead sources. The dominant lead ratio found in Greenland snow matched that found ingasoline from the United States. In a study published in the journal Ambio, scientists found that levels in soil in the Northeastern Uni
6、ted States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period. The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New
7、England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected. Scientists say both studies demonstrate that certain parts of the ecosystem respond rapidly to reductions in atmospheric pollution, but that th
8、ese findings should not be used as a license to pollute.1 The study published in the journal Nature indicates that(A)the Clean Air Act has not produced the desired results.(B) lead deposits in arctic snow on the increase.(C) lead will stay in soil and snow longer than expected.(D)the U.S. is the maj
9、or source of lead pollution in arctic snow. 2 Lead accumulation worldwide decreased significantly after the use of unleaded gas in the U.S.(A)was discouraged.(B) was enforced by law.(C) was prohibited by law.(D)was introduced. 3 How did scientists discover the source of lead pollution in Greenland?(
10、A)By analyzing the data published in journals like Nature and Ambio.(B) By observing the lead accumulations in different parts of the arctic area.(C) By studying the chemical elements of soil and snow in Northeastern America.(D)By comparing the chemical compositions of leaded gasoline used in variou
11、s countries. 4 The authors of the Ambio study have found that(A)forests get rid of lead pollution faster than expected.(B) lead accumulations in forests are more difficult to deal with.(C) lead deposits are widely distributed in the forests of the U.S(D)the upper layers of soil in forests are easily
12、 polluted by lead emissions. 5 It can be inferred from the last paragraph that scientists(A)are puzzled by the mystery of forest pollution.(B) feel relieved by the use of unleaded gasoline.(C) still consider lead pollution a problem.(D)lack sufficient means to combat lead pollution. 5 It came as som
13、ething of a surprise when Diana, Princess of Wales, made a trip to Angola in 1997, to support the Red Crosss campaign for a total ban on all anti-personnel landmines. Within hours of arriving in Angola, television screens around the world were filled with images of her comforting victims injured in
14、explosions caused by landmines. “I knew the statistics,“ she said, “But putting a face to those figures brought the reality home to me; like when I met Sandra, a 13-year-old girl who had lost her leg, and people like her.“ The Princess concluded with a simple message: “We must stop landmines“. And s
15、he used every opportunity during her visit to repeat this message. But, back in London, her views were not shared by some members of the British government, which refused to support a ban on these weapons. Angry politicians launched an attack on the Princess in the press. They described her as “very
16、 ill-informed“ and a “loose cannon (乱放炮的人 ).“ The Princess responded by brushing aside the criticisms: “This is a distraction we do not need. All Im trying to do is help.“ Opposition parties, the media and the public immediately voiced their support for the Princess. To make matters worse for the go
17、vernment, it soon emerged that the Princesss trip had been approved by the Foreign Office, and that she was in fact very well-informed about both the situation in Angola and the British governments policy regarding landmines. The result was a severe embarrassment for the government. To try and limit
