题目内容
15. the address,Tom sent the email to his teacher.( )A. | Having checked | B. | Checked | C. | Being checked | D. | To check |
分析 核对了地址后,Tom给他的老师发了一封电子邮件.
解答 答案:A
题干中有逗号分隔,没有连词,要用非谓语动词;句中check与主语Tom之间构成主谓关系,要用主动;句意表达的check动作发生在谓语动词sent之前,要用分词的完成式.故选A.
点评 非谓语动词是常考的语言点.有三种构成方式:现在分词表示主动和进行的动作;过去分词表示被动和完成;动词不等式表示未发生的动作.学习时,要注意区分和掌握.
