如何判断 一般现在时
如何判断 一般现在时
一般现在时的基本结构分为两种:
1.主语+Be动词(is,am,are)+表语(否定式是在Be动词后加not,疑问句是将Be动词提前到句首)(即在主语之前)
e.g.:I am a man.我是一个男人
2.主语+动词(若是第三人称单数+s或es)
e.g.:He plays football everyday.他天天踢足球
一般现在时的概念:
表示通常性、规律性、习惯性的状态或者动作(有时间规律发生的事件)的一种时间状态.
一般这些词出现基本都是表示一般现在时的:
usually,often,always,sometimes,regularly,near,occasionally,every year,every week,everyday等等.
判断方法:
可以通过一般现在时基本结构与句子结构结合判断
可以通过句子含义与一般现在时概念结合判断

4The pot_____(not look) like yours very much.
5 Where _____you____(have)lunch every day?
6 Who_____(想要 )to go swimming?

8 Jenny and Danny usually______(play) games in the afternoon .
答案:1 comes 2 Does know 3 is away from 4 doesn't look
5 do have 6 wants 7 does do 8 play
二、单三人称形式易出错
例:1 He plaies (play) football very well.
2 Danny gos (go) to school at 7:10.
答案:1 plays 2 goes
解析:1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es;2与名词变复数不同,变单三人称形式以o结尾的词要加es.
三、在句式变换时易出错
例:1 Does Jenny has (has) a good friend?
2 Brian doesn’t lives (not live) in China.
答案:1 Does have 2 doesn’t live
解析:单三人称做主语的一般现在时做句式变化时,可记住如下口诀:“见助动,用原形”。此口诀也可推广用于一般过去时态中。e.g. He didn't go home
yesterday.
四、对do的理解易出错
例:We don’t (not do) our homework in the afternoon.
答案:don’t do
解析:do是一个比较难理解的词,它有三个含义:
a)是所有行为动词的总称;b)是助动词,无实义;c)是一个具体的行为动词“做,干”。此句中给出的do指“做,干”,not指把此句变为否定句,故须在do前加助动词don’t。
五、对主语的数判断有误
例: Li Ming with me are (be) in Beijing.
答案: is
解析:表面一看是“我和李明两个人在北京”,但with在此做伴随状语,不能做主语,故用is.
另外,宾语从句中,从句部分若是表示客观真理,不管主句是何时态,从句都要用一般现在时;在时间和条件状语从句中,主句表将来,从句要用一般现在时。
