1.现在进行时

动词-ing 形式的构成

一般情况下，在动词词尾后加-ing。如：go → going。

以不发音的 e结尾的动词，去掉 e加 -ing。如: have → having。

以重读闭音节结尾的动词，末尾只有一个辅音字母，双写这个辅音字母，再加 -ing。如：

stop → stopping。

2.现在完成时

过去分词构成规则

一般情况下，在动词后加-ed。如: work → worked。

在以 e结尾的动词后只加 -d。如: close → closed。

在以辅音字母加 y结尾的动词，应将 y改为 i再加 ed。如: study → studied。

3.被动语态

主动语态和被动语态的区别

主动语态表示主语是动作的执行者。被动语态表示主语是动作的承受者，即行为动作的对

象。

I cleaned my room. → My room was cleaned by me.

I saw him cross the road and enter the shop. → He was seen to cross the road and enter the shop.

在含有使役动词 (make, let 等) 或感官动词 (see, watch, notice, hear 等) 的主动语态的句子中，

这些词后常跟省略 to 的动词不定式，但是改为被动语态时则要把省去的 to 还原。

被动语态的构成

被动语态的构成：be + 过去分词

一般现在时被动语态：am/is/are + 过去分词

一般过去时被动语态：was/ were + 过去分词

一般将来时被动语态：will be/ is going to be + 过去分词

情态动词的被动语态：can/could/may/might/should/must + be + 过去分词

4.情态动词

1. 情态动词通常无人称和数的变化。

2. 情态动词后接动词原形。

3. 情态动词有：can/could 能够；may/might 可能、可以；need 需要；

have to 不得不；would 愿意、将要；shall 将(第一人称)；

should 应该；must 必须
