一般现在时
用法总结　一般现在时的构成
一般现在时用动词的原形表示。当句子的主语是第三人称单数时,谓语动词要用“三单”形式。变化规则如下:
情况规则举例
一般情况加-slove→loves
以字母-s, -sh, -ch, -x结尾的动词加-espass→passes catch→catches push→pushes mix→mixes
以辅音字母加-y结尾的动词变y为i再 加-esfly→flies
知识拓展　一般现在时的用法主要有:
1.用来描述目前的习惯性、经常性的动作或状态。例如:
I go to work at 7:00. 我七点去上班。
She is always ready to help others. 她总是乐于助人。
2.用来描述客观真理、定律、事实、自然现象。即使出现在过去的语境中,一般也用一般现在时。例如:
The sun rises in the east. 太阳从东方升起。
He taught me that hydrogen is a light gas. 他教过我,氢气是一种很轻的气体。
3.以Here/There开头引导的倒装句,一般现在时表示现在正在发生的动作或存在的状态。例如:
Here comes the bus. 公交车来了。
There goes the bell. 铃响了。
