初中常用动词时态

( 1 )一般现在时:主语+动词原形/动词的第三人称单数形式+其他;
( 2 )一般过去时:主语+动词的过去式+其他;
( 3 )现在进行时:主语+am/is/are+动词的现在分词+其他;

2.时态标志词: 语法精讲
注意:以下几种情况多用一般现在时。
①在if,unless等引导的条件状语从句中和when,until,as soon as等引导的时间状语从句
中,当主句是一般将来时,从句通常用一般现在时表示将来。例如:
We’ll have a sports meeting if it doesn’t rain next Saturday.如果下周六不下雨,我们将
举行运动会。
②宾语从句部分陈述的是客观真理,不管主句是何时态,从句都要用一般现在时。例
如:
My mother told me that the sun rises in the east.我的妈妈告诉我太阳从东方升起。语法精讲
3.非延续性动词和延续性动词在现在完成时中的应用:
若句中出现时间段,则必须使用延续性动词。例如:
Her lovely dog has been dead for 10 days.她那只可爱的狗死了已经有10天了。
常见的非延续性动词与延续性动词之间的转化:语法精练
