Reading Comprehension (30) Passage 1 In the old days, divers (潜水员) used to go down into the sea looking for ships that had sunk, because they hoped to find gold and jewels. Now divers still search fro valuable things in sunken ships, but they also try to bring to the surface the ships themselves, or parts of them. The value of different kinds of metals has increased greatly over the last twenty or thirty years and even though a ship has been under the sea for many years, it may be wroth a great deal. One famous sunken ship is the “Lusitania ”, which sank off the southern coast of Ireland in 1915 with a loss of nearly 1,500 lives. It has four huge propellers (螺旋桨) made of an expensive metal. Today each of those propellers is worth $300,000 or more. The ship, lying on the sea-bed, has been bought by a man called John Light. He paid about $1,200,000 for the whole ship. He hopes to bring up those propellers and sell them. He also hopes to sell other parts of the ship, when he has brought them to the surface, for about $600,000. 61. Divers today try to bring to the surface______. A. gold and jewels B. parts of ships C. whole ships D. all of the above 62. Divers try to bring up metals because _______. A. they have been in the sea for a long time B. gold and jewels are not valuable things C. some kinds of metals are worth a lot of money today D. it is easy to bring up metals 63. The word “surface ” in the passage means the _____. A. market B. air C. top of a liquid D. sea 64. John Light hopes that he may be able to sell all the parts of the Lusitania for about _______. A. $ 12,000 B. $300,000 C. $1,200,000 D.$1,800,000 65. John Light bought the “Lusitania ” ______. A. before 1915 B. before it sank C. after it sank D. after he had brought up the propellers Passage 2 WASHINGTON, Sept. 23 -- The House of Representatives, which prides itself on being" the People's House" has been turning into a rich men's club. The representatives newly elected in 1984 were almost four times as wealthy as the first term lawmakers elected only six years before, according to a new study on the members' financial reports. Behind this remarkable swing, the study says, there are two main factors: a court decision that outlawed limits on what candidates could give to their own campaigns, and the enormous growth in the cost of pursuing a seat in Congress. As a result, it is increasingly difficult for candidates of modest means, particularly women to amount successful challenges to entrenched office holders. One solution, the authors contend, is a system of public financing for campaigns, but Congress seems in no mood to change the political rules any time soon. "The lower chamber is going upper class," said Mark Green, the President of the Democracy Project, a public policy institute based in New York. "But this evolution from a House of Representatives to a House of Lords denies the diversity of our democracy. It establishes a de facto property qualification for office that increasingly says: The people with low and middle income need not apply." The Democracy Project produced the study in cooperation with the United States Public Interests Research Group, a similar institute situated in Washington. But their research was not entirely theoretical. In 1980 Mr. Green was the unsuccessful Democratic candidate for Congress in New York' s 15th District, in Manhattan. The winner was Bill Green, one of the wealthiest members of Congress. 66. What can we know from the passage? A. The House of Representatives is poor men' s club. B. The House of Representatives was made up of people with low and middle income. C. The House of Representatives was rich men' s club. D. The House of Representatives is made up of people with low and middle income. 67. What does "this remarkable swing" in the third paragraph refer to7 A. The House of Representatives prides itself on being "the people' s House". B. The new study based on the members' financial reports. C. A court decision that outlawed limits on what candidates could give to their own campaigns. D. The representatives elected now are much wealthier than those elected a few years ago. 68. Which of the following is wrong according to the study? A. Any honest man can become a representative of the House. B. Women are more difficult than men to be an entrenched office holder. C. Limits on what a candidate could give to his campaign are outlawed. D. One must spend much money getting a seat in the Congress. 69. What is the United States Public Interests Research Group like? A. The House of Representatives. B. A public policy institute based in New York. C. A public policy institute based in Washington. D. The House of Lords. 70. What does the writer think of the study? A. Doubtful. B. Believable. C. Opposed. D. Normal. 71. 这篇新闻报道是完全根据实际情况写成的。
