OG91

今天又看到了OG91，对ETS的解释还是很是疑惑？Choices B and E, which replace A's prepositional phrase with clauses introduced by as, use auxiliary verbs that cannot properly be completed by any part of the verb phrase in the main clause: neither have ... did not begin nor did... did not begin is logically or grammatically sound.

如果是因为did不能表达否定的意思，即As A did, B didn't or A did, As B didn't这种结构不正确的话，那末这道题又如何解释呢？XDF的题。

Because young children do not organize their attention or perceptions systematically, like adults, they may notice and remember details that their elders ignore.

(A) like adults

(B) unlike an adult

(C) as adults

(D) as adults do

(E) as an adult

答案是D.恳请各位解答！

Because young children do not organize their attention or perceptions systematically, like adults, they may notice and remember details that their elders ignore.

(A) like adults

(B) unlike an adult

(C) as adults

(D) as adults do

(E) as an adult

如果不用as adults do就会产生歧义，究竟是象成年人那样organize......还是象成年人那样may notice and remember......。在此插入语中用了do就明确是跟前面的分句，反之则用as adults may.

这一点我明白，也知道OG91选like更好，但是这两道题的确是互相矛盾的，按照ETS的说法

，as adjults do中的do也不能表达do not organize的意思啊！

刚才仔细看了一下，明白了！

Like many self-taught artists, Perle Hessing did not begin to paint until she was well into middle age.
(A) Like
(B) As have
(C) Just as with
(D) Just like
(E) As did
需要表达的是相似性，所以说did没有办法表达did not的意思；而XDF的题因为是需要表达不同，所以as adults do不需要表达do not的含义！

Because young children do not organize their attention or perceptions systematically, like adults, they may notice and remember details that their elders ignore.

(A) like adults

(B) unlike an adult

(C) as adults

(D) as adults do

(E) as an adult

谢谢大家！

这末看来，在as/like的选择的时候，还要考虑到表达的是相似性还是不同罗！

而且由此看来，like只能表达相似性（不管是肯定还是否定的），as既可以表达相似性，又可以表达相反！

还请大家解答！
