More than 30 years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to another.

as pearls moving mysteriously from one necklace to another

like pearls moving mysteriously from one necklace to another

as pearls do that move mysteriously from one necklace to others

like pearls do that move mysteriously from one necklace to others

as do pearls that move mysteriously from one necklace to some other one Clauses have subjects and verbs and are introduced by conjunctions or relative pronouns; phrases do not have subjects and verbs and are frequently introduced by prepositions. The preposition like, not the conjunction as, should introduce the underlined phrase. A       As incorrectly introduces a phrase when like is required B        Correct. In this sentence, the preposition like properly introduces the phrase. C       McClintock's simile creates an image that is not real; the use of the verb do indicates the pearls' movement as a reality D       Like incorrectly introduces a clause; the verb do indicates a reality instead of an image that is only imagined E        Pearls do not actually move; McClintock is suggesting an image only. Some other one is a wordy replacement for another

答案是B ,  但是我不太明白ETS的解释,为什么不能用AS , 是说 这只是个比喻而不是真的,所以只能用like , 不能用as 嘛?  如果这样用as 可以嘛? as pealrs move mysteriously from one  necklace to another

两年多了哈...
本来也打算上网问的,看到楼主这么问,突然之间想明白了!其实ETS解释已经很清楚了:
Clauses have subjects and verbs and are introduced by conjunctions or relative pronouns; phrases do not have subjects and verbs and are frequently introduced by prepositions. The preposition like, not the conjunction as, should introduce the underlined phrase.

 

A的话,其中的"as"是作为连词的,那么连词后面就必须是一个完整的句子.而as后面是没有一个谓语动词的,所以A选项不对.
这里"moving mysterious..."分词形式是用来修饰perals,所以用like pearl...是正确的做法!

希望我不要一错再错了,哎,苦海无涯,回头是岸阿!

这道题除了考察as和like的区别之外，我觉得还考察了比较结构的对称。

我的理解是：genes can jump和pears move是动作上的比较，但是正确答案B却比较的是动作和pears，因为moving的结构作后置定语修饰pearls。所以做这道题时选了C，而忽略了move动作的真实性。

是我理解的问题，还是这道题本身有瑕疵呢？

Molybdenum

简言之：

区别就是，as是“作为”，也就是事实本来就是这样，like是“像”，事实并不是这样。

所以as pealrs move mysteriously from one  necklace to another  就好像在说真的有些peal 滚着~

实际上并没有。

好题~

但是like不能引导从句，as可以。

这道题比较的双方不应该是动作吗？

Molybdenum

比较是灵活的，当语法支持的时候，1L最后给出的是最好的结构，但是这个题没有这个结构，那么比

较主语的两个名词也是可以的，后面的分词作为修饰部分，也把情况说明了。毕竟不是全句大比较，对含

义的影响不大。

XDF的老师不是说like不能放在句尾么......说放在句尾都是错的....

Avantasia

不确定……

这样的规则需要谨慎对待

个人以为

这道题，如果用as，会造成歧义：

因为前面是有两个动作，report, jump, 如果用as pearls do, 那么到底是指pearls report as Dr. BM report呢，还是pearls jump as genes jump?

参考Prep2-29

对于当AS和Like意思是像XXX一样的时候，

As+ clause

Like+ phrase

So i think actually if the answer is 'as perls movemysteriously from one necklace to others' is also acceptable.

but answer C use ' as pearls do that move mysteriously from one necklace to others', and 'do that move' means the acually pearls 'moves'.

According to the main sentence, 'genes can jump' and 'pearls move' is just a imagination and a simile, thus it is not suitable to use ' do the move' to indicate the move of the pearl.

希望大家讨论。
