Question

【题目】—Have you finished your homework_____, Tom?

—Yeah, I ____ it half an hour ago.

A. yet, have finished B. already, have finished

C. yet, finished D. ever, finished

Answer 1

【答案】C

【解析】

句意：——汤姆，你已经完成作业了吗？——是，我半小时前完成了它。yet已经，用于否定句或一般疑问句；already已经，是肯定句。第一空是一般疑问句，故用yet。第二空根据half an hour ago可知此处用一般过去时，故选C。
