AnswerA)

虽然我也选对了A,可是真的是靠"所谓的语感"选出来的...如果说B和C还可以较容易排除的话,那么D和E怎么解呢?我觉得D和E也没有什么太大的问题呀~~~~~~请NN指点!!谢谢!!

对了,还有一道~~~也不是很明白:

As a result of a supernova explosion, every human being on Earth was bombarded on February 23, 1987, by about 100 billion neutrinos; fortunately, neutrinos are harmless elementary particles that are produced in nuclear reactions and that interact very weakly with matter.

 

(A) neutrinos are harmless elementary particles that are produced in nuclear reactions and that

(B) neutrinos, which are harmless, are elementary particles produced in nuclear reactions and which

(C) neutrinos are harmless elementary particles produced in nuclear reactions and which

(D) these harmless elementary particles are produced in nuclear reactions, and neutrinos

(E) these elementary particles, harmless products of nuclear reactions, are neutrinos that

我选了E,E怎么不对了呢?

LZ 举的这两道题都有一个同样的问题：改变原句的意思。

As a result of a supernova explosion, every human being on Earth was bombarded on February 23, 1987, by about 100 billion neutrinos; fortunately, neutrinos are harmless elementary particles that are produced in nuclear reactions and that interact very weakly with matter.

 (A)   neutrinos   are harmless elementary particles that are produced in nuclear reactions and that

 (A)   neutrinos   are harmless elementary particles that are produced in nuclear reactions and that

(E) these elementary particles, harmless products of nuclear reactions, are neutrinos that

原句中A的主语 变成了E中的宾语，宾语变成了主语。

这样有两个问题：

1.强调的重心变了。尤其是在从一个特指概念改变成比较泛指的概念时。 比如 苹果是一种水果 和 一种水果是苹果。这两个句子所强调的中心就不一样。前者强调的中心是 苹果 是一种什么东西，而後一个句子这种强调就没有了，只是指出一个东西。

2.由于后面有that 限制性从句，这种结构的改变同时造成 that 从句修饰的对象改变，意思也就不对了。

More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.

(A) More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.

(A) More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.

这个句子的主干是rivers drain into Siberia's Lake Baikal ，后面的都是其修饰成分。

(D) While more than 300 rivers drain into it, Siberia's Lake Baikal holds 20 percent of the world's fresh water, which is more than all the North American Great Lakes combined.

(E) More than all the North American Great Lakes combined, Siberia's Lake Baikal, with more than 300 rivers draining into it, holds 20 percent of the world's fresh water.      

==》D 和E 选项的句子主干都变成了Siberia's Lake Baikal holds 20 percent of the world's fresh water， 原来的主干变成了修饰成分。

Oh...I see...原来在做长段的语法题里还要考虑主干是否被"偷换"了的...谢谢NN的祥解,已记下来了
