以下是引用tianwan在2004-4-5 12:04:00的发言:
101.Although the Supreme Court ruled as long ago as 1880 that Blacks could not be excluded outright from jury service, nearly a century of case-by-case adjudication has been necessary to develop and enforce the principle that all juries must be drawn from “a fair cross section of the community.” (A) has been necessary to develop and enforce the principle that all juries must be (B) was necessary for developing and enforcing the principle of all juries being (C) was to be necessary in developing and enforcing the principle of all juries to be (D) is necessary to develop and enforce the principle that all juries must be (E) will be necessary for developing and enforcing the principle of all juries being 此题已讨论过,答案是A。但我觉得B应该是答案。
1,nearly a century并没有指明终点是现在,所以不能证明现在完成时。只能证明过去时。
嘻嘻,我猜这个句子是1980左右写的。其实语态可以从前面一句话中猜出,早在...., 但是现在仍然需要.....
2,我们说it is necessary (for somebody) to do something不定式做主语,但是sth is necessary for (doing)sth(不定式不可能做主语,没有it作形式主语)。
同意你对necessary for 的看法。
3,of短语是可以做同位语的,所以principle of all juries beinn blabla.是可以的。请参阅《高级英语语法,薄冰》P473,474,和《新编英语语法,章振邦》P1362,
principle of 没问题,但是后面的being 后问题。根据EST的看法,这种of sth being 的结构显然不如 that 从句表达清晰。
一家之言,请指正。
所以还是A。
