2022学年牛津上海版英语七年级第二学期语言点及练习unit3
一、语言点整理
1. (1)She has been a teacher since 1997 自1997年以来,她一直是一名教师。
(2)She has been a teacher for quite a few years. 她当教师已经好些年了。
· since 是现在完成时的一个标志词
· 请注意,since后接“一个时间点”,如:since last Monday/three o’clock等。Since 还可以引导时间状语从句,一般来说从句要使用过去时。如: He has been a teacher since he left the university.
· for后则接“一段时间”,如:for two hours/months等,又如:Aunt Judy and Uncle Jack have lived in Los Angeles for six years.
· 现在完成时基本结构: have/ has done(动词的过去分词)。
· 在现在完成时的句子中如果有since/for 引导的时间状语,句子中的谓语就表示持续的动作涵义,必须使用持续性动词,而不可使用短暂性动词。
Eg: 1) I have been in the club for three years. √
2) I have joined the club for three years. X (join是短暂性动词)
· 对since/for引导的时间状语提问要使用How long
She has been a teacher for a quite a few years. 她当老师有好几年了?
How long has she been a teacher? 她当老师多久了?
2. Aunt Betty works in a company in Beijing, doesn’t she?贝蒂姨妈在北京一家公司工作,对吗?
