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

(C) developed only after Harry Truman’s support of 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

(C) not only by the foods patients eat but also by time when the foods are eaten

(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。

谢谢，又有收获也！很happy
