Question

【题目】Tom by his classmates because he made a careless mistake.

A. laughed at B. was laughed at

C. laughed D. was laughed

Answer 1

【答案】B

【解析】句意：汤姆因为犯了一个粗心的错误而被同学们嘲笑。根据句意“汤姆因为犯了一个粗心的错误而被同学们嘲笑”以及原因状语从句使用一般过去时，可知主句要用一般过去时的被动语态，其结构为：was/were+动词过去分词，主语是Tom，所以用was，laugh at sb.嘲笑某人，laugh的过去分词是laughed，故答案选B。
