3.The day we were looking forward to ____ finally, when we won the first prize.

A. came B. coming

C. come D. had come

【答案】A

【解析】

【详解】考查时态。句意：我们期待的那一天终于来了，我们赢得了一等奖。此处The day是先行词，后面we were looking forward to是定语从句，所以句子缺少谓语动词，而不是look forward to doing sth."期盼做某事结构"。结合句意句子用一般过去时态，故答案为A。

4.With all your energies ______ the study of French, you will master the language.

A. concentrated B. concentrating

C. concentrated on D. concentrating on

【答案】C

【解析】

【详解】考查动词短语和过去分词。句意：把全部精力集中在学习法语上，你就会掌握这门语言。动词短语：concentrate on集中精力于，全神贯注于。此处是with引导的独立主格结构，"with+宾语+过去分词"做条件状语，energies和concentrate之间是被动关系。故选C。

5.The twins, who _____ their homework, were allowed to play badminton in the yard.

A. will finish B. finish

C. have finished D. had finished

【答案】D

【解析】

【详解】考查时态。句意：做完作业的那对双胞胎获准在院子里打羽毛球。结合句意who _____ their homework中的动作先于主语谓语动词动作were allowed，也就是"过去的过去"，所以句子用过去完成时态，故选D。
