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：

3Her home____ _____ ______(远离 )her school.
4The pot_____(not look) like yours very much.
5 Where _____you____(have)lunch every day?
6 Who_____(想要 )to go swimming?
7 ______she_____(do) the housework every day?
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。
