标题: 请教大全259

259.During Roosevelt’s years in office Black Americans began voting for Democrats rather than Republicans in national elections, but Black support for Democrats at the state and local levels developed only after when civil rights legislation was supported by Harry Truman.

(A) developed only after when civil rights legislation was supported by Harry Truman

(B) developed only after when Harry Truman supported civil rights legislation

(D) develops only at the time after the supporting of civil rights legislation by Harry Truman（C）

(E) developed only after there being Harry Truman’s support of civil rights legislation

想知道B为什么不对？我的理由是

1.support是抽象名词没有动词support用好。

2.prep后面可以跟名词性从句的eg：

238.Dental caries and gingivitis can be exacerbated not only by the foods patients eat but also by when the patients eat them.

(A) not only by the foods patients eat but also by when the patients eat them

(B) by not only the foods patients eat but also by when the patients eat them

(D) by not only the foods that are eaten by patients but also by the times the foods are eaten（E）

(E) not only by what patients eat but also by when they eat it

正确答案E

谢谢先

259中after / when两个代表时间的词同时出现，错。

238what引导的主语从句一般作为单数，what指the food that，而it指what含的food；what/when引导两个名词从句，结构平行。

我觉得259的B错是因为 after when……有问题，它们两个都是表示时间的连词放在一起用不正确。又是after又是when，那到底是after还是when呢？但是by when……就可以，因为by是介词，后面的when 引导的是名词性从句。
