Question

考试之后，我一定是听上去洋洋得意，说考题实在太简单了，我肯定能取得好成绩。（汉译英）

Answer

I must have sounded very proud of myself after the quiz, saying how easy it was and how I was sure to get a good grade.

【解析】

考查情态动词的完成时态和非谓语动词。分析句子结构可知，空处需用must have done，表示对过去情况的肯定推测，after the quiz考试后，时间状语从句，结合汉语句意可知，本句是对过去情况的肯定推测，所以本句的谓语动词需用must have done，后需接sound proud of myself听上去洋洋得意，固定短语；此处动词say与主句主语I之间是主动关系，所以此处需用现在分词saying作状语，后接how easy引导宾语从句，其后接it is；再结合汉语提示可知，此处需用and引导两个并列的宾语从句，第二个从句需用how引导宾语从句，从句的主语是I，后接 was sure to do sth.肯定做某事，get a good grade取得好成绩。故翻译为：I must have sounded very proud of myself after the quiz, saying how easy it was and how I was sure to get a good grade。
