七八年级动词时态（六种）复习课件 (共38张PPT).ppt

林书豪已经在美国生活了多长时间了？ how long has Jemery Lin lived in America？ He has lived in America since he was born. He has lived in America for 27 years old. 他从出生就在美国住。 他在美国住了27年了。 如何判断现在完成时 1.找标志词 2.联系上下文语境，看过去发生的事情是否对现在造成影响 already , yet , just, before, so far, since +时间点, for +时间段 知道了要用现在完成时，那现在完成时该怎么写，那就要知道它的构成。请记住它的构成： have/has +过去分词（-ed） 7. — How clean the bedroom is ！ — Yes, I am sure that someone ____ it. A cleans B cleaned C has cleaned D had cleaned C 剖析：首先看四个选项，都是动词clean的四个时态，由第一句我们得知这个卧室很干净，而第二句猜测是有人打扫了。根据上下文语境，说明“过去打扫的动作”对现在产生了影响“卧室干净”。所以用现在完成时，根据现在完成时的构成，故答案是C 真题演练 8. ----Hasn’t Betty come yet? ----No, and I____ for her for more than 2 hours. A wait B waited C have waited D had waited c 剖析：看四个选项，就知道考查时态的，根据上下文语境、特别是答句里的标志for nearly 2 hours, 我们就应该选现在完成时，根据现在完成时的构成，所以答案是C。 同学们，今天我们复习了六种时态，“如何利用三部曲将时态进行到底!”是我们这节课的主旨。让我们最后用半分钟扫描一下这些时态的标志和构成吧！ 时态 标志 构成 一般现在时 usually, often, sometimes, every day , every year, in the morning, on Sunday..... 动词原形/ 第三人称单数 一般过去时 yesterday, yesterday morning..., last year, in 2003 动词的过去式 现在进行时 Listen!
