Passage2

如题
In the first year or so of Web business, most of the action has revolved around efforts to (1) tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because businesspeople typically know what product they're looking for.

55. We learn from the beginning of the passage that Web business__
A. has been striving to expand its market
B. intended to follow a fanciful fashion
C. tried but in vain to control the market
D. has been booming for one year or so

首先我根据market与product的关系排除B、D 。但是A、C我找不到近义词互换

But it is hardly inevitable that companies on the Web will need to resort to push strategies to make money. The examples of Virtual Vineyards, Amazon.com, and other pioneers showthat a Web site selling the right kind of products with the right mix of interactivity, hospitality, and security will attract online customers. And the cost of computing power continues to free-fall, which is a good sign for any enterprise setting up shop in silicon. People looking back 5 or 10 years from now may well wonder why so few companies took the online plunge

58. We learn from the last paragraph that __
A.pushing information on the Web is essential to Internet commerce
B.interactivity, hospitality and security are important to online customers
C.leading companies began to take the online plunge decades ago
D.setting up shops in silicon is independent of the cost of computing power

如果让我选我会选c 因为有plunge， 虽然不满足>=2原则 答案却是B

When a Scottish research team startled the world by revealing 3 months ago that it had cloned an adult sheep, President Clinton moved swiftly. Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment- although no one had proposed to do so--and asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with recommendations for a national policy on human cloning. That group--the National Bioethics Advisory Commission (NBAC)-has been working feverishly to put its wisdom on paper, and at a meeting on 17 May, members agreed on a near-final draft of their recommendations.

63. We can learn from the first paragraph that__.
A. federal funds have been used in a project to clone humans
B. the White House responded strongly to the news of cloning
C. NBAC was authorized to control the misuse of cloning technique
D. the White House has got the panel's recommendations on cloning
