三、一般过去时与现在完成时的区别

一直延续到现在或过去发生的动作对现在造成的影响。

2.一般过去时的时间状语有yesterday, last week, …ago, in 1980, just now等;现在完成时的时间
状语有for…, since…, so far, ever, never, just, yet等,有时候现在完成时没有时间状语。

现在完成时(有时也用一般过去时)。

四、动名词的用法
1.意义:动名词由“动词原形+-ing”构成,可以起名词的作用。

2.用法:(1)动名词做主语,谓语动词用单数形式。

早晨朗读英语对学生有好处。

(2)动名词做表语,表示主语是什么,而不是主语的性质或特征如何。

(4)动名词做定语,表明它所修饰的词的用途、所属关系等。
