GWD21-Q1:

According to analysts, an alliance between three major personal computer companies and most of the nation’s largest local telephone companies would enable customers to receive internet data over regular telephone lines with speeds much higher than is currently possible.



A.      with speeds much higher than is

B.      with speeds that are much higher than are

C.      at much higher speeds as are

D.      at much higher speeds than that

E.       at speeds much higher than are

答案为E

疑惑：此题是明显的比较的平行结构，所以比较双方的谓语动词应该是统一的，而companies enable sth to do..than    currently possible. 所以一这个currently possible 前面不应该是be动词吧？

Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture to 1950.

A.      Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture

B.      Between 1990 and 2000 the growth of the global economy was more than that during 10,000 years, from when agriculture began

C.      The growth of the global economy between 1990 and 2000 exceeds that which had been for 10,000 years from the beginning of agriculture

D.      The growth of the global economy between 1990 and 2000 exceeds what it has been for 10,000 years, from when agriculture began

E.       The growth of the global economy between 1990 and 2000 exceeded what it did for the 10,000 years from the beginning of agriculture

答案为A

两个疑问：

1.是介词+when 是正确吗？

2.仍然是平行结构：但是during the 10000不是应该用完成时态吗？



A survey of entrepreneurs who started companies last year shows that while virtually all did substantial preparatory research and planning, only half used that work to produce a formal business plan.  Since, on average, the entrepreneurs without formal plans secured the capital they needed in half the time of those with plans, these survey results indicate that, in general, formal plans did not help the entrepreneurs who produced them to secure the capital they needed.

Which of the following, if true, most seriously weakens the argument?

A.      Companies started by entrepreneurs who had used formal business plans to attract investment were on the whole as profitable in their first year as were companies started by entrepreneurs who had not produced such plans.

B.      In surveys of entrepreneurs who have attempted without success to raise sufficient capital, more than half of the respondents indicate that they have produced a formal business plan.

C.      Among the entrepreneurs surveyed, those who did not produce formal business plans sought and received a much larger proportion of their capital from investors with whom they had a long-standing business relationship.

D.      The entrepreneurs surveyed who did not produce a formal business plan spent nearly as much time doing preparatory research and planning as the entrepreneurs who produced plans.

E.       The entrepreneurs who produced business plans generally reported later that the process of writing the plan had increased their confidence that their company would succeed.

答案为C

疑问：全文主要要weaken的应该是“有formal plan的并没比没有formal plan的更加有优势。”但是答案却是说“没有formal plan的大部分的capital是从他们的长期合作伙伴中搜寻的。”而且文章是“说获取他们寻妖的capital并没有说capital的来从是从新的合作伙伴中获取更好还是从老合作伙伴中获取更好”所以我认为C答案没有从本质上说明formal plan是有用的。反而可能会起增强的作用。

但是其他的选项有明显感觉不合适：

A说两个一样。B是support 。D是是个无关信息。E倒是说明了formal plan的一个优点，所以我认为“只能在矮子里面挑将军”的话，E相对更加的合适。



请教谁能帮我解答这道纠结的题目？
