由OG-92想到替代的问题

snow_mountain

楼上的，偶OG的解释都贴出来了，你都不看。  白贴了。

In choice C, the best answer, do is correctly used in place of the full verb do sell;

兄弟们，92，d~~confronted到底可不可以被did  替换哪？定论在哪儿哩？？我等得！

不可以,og里有一题曾经明确指出过

如果前后时态一致,可以在后面简化,如果前后不一致,一定要写全动词的具体形式,此题就是过去时的confronted, 如果改成did, 找不到合适的前方指代对象

       Inflation has made many Americans reevaluate their assumptions about the future; they still expect to live better than their parents have, but not so well as they once thought they could.

(A) they still expect to live better than their parents have

(B) they still expect to live better than their parents did

(C) they still expect to live better than their parents had

(D) still expecting to live better than their parents had （B）

(E) still expecting to live better than did their parents

marie MM: 那么为什么这里答案B可以用did代前面的live而不用lived呢？

谢谢指点。

It seems that a straight forward substitution (simple present -> simple past) is encouraged... another example:

OG 168B: Today, because of improvements in agricultural technology, the same amount of acreage produces twice as many apples as it did in 1910.

when it involves more complicated tenses, be very careful (meaning clear & concise ) in 92D and OG 187A:

In one of the bloodiest battles of the Civil War, fought at Sharpsburg, Maryland, on September 17, 1862, four times as many Americans were killed as would later be killed on the beaches of Normandy during D-Day.

fyi: there is a thread discussing the same issue: OG-92只有五天了,请NN们帮个忙.

多多讨论．．．
