含be动词的一般现在时

含行为动词的一般现在时
思考:什么是“行为动词”?
行为动词也可称为“实义动词”,有本身实际含义的动词,在句子中可做谓语,也叫“谓语动词”,一般现在时主要通过谓语动词的变化来表示。
Marry usually comes to school by bike.
Marry doesnt usually come to school by bike.

如:teach (动词原形)——teaches(动词单三形式)

动词的第三人称单数的变化方式基本上和名词复数的变化是一样的
3、以辅音字母+y结尾的动词,把y改为i,再加es
如: fly (动词原形)——flies(动词单三形式)
study(动词原形)——studies (动词单三形式)
1、一般情况下,在动词后+s
如:look (动词原形)——looks (动词单三形式)
get (动词原形)——gets (动词单三形式)
对一般现在时的考查
1.考查其基本概念:一般现在时常表示一个习惯性、经常性的动作以及客观事实或普遍真理。但近几年,对一般现在时的考查常用过去时态或现在完成时态对考生进行干扰。

2.This girl is ready to help people any time. When she is on the bus, she always her seat to someone in need.(2011, 四川绵阳)
