©PAN ASIA PUBLICATIONS
英文里有四种形式的动词：

Base Form (vb) Past Form (pt) Past Participle Continuous
Form (pp) Form (v-ing)
play played played playing
buy bought bought buying
give gave given giving
have had had having
be (is/am/are) was/were been being

Most verbs are regular like ‘play’ in the table above. -ed is added to form the
simple past and past participle.
大多数动词都是规则动词，就像上表中的 play。在词尾加 -ed 就可构成简单
过去式和过去分词。
repair – repaired – repaired
However, some other verbs can be irregular such as ‘buy’ and ‘give’.
然而，也有一些动词是不规则动词，如 buy 和 give。
fly – flew – flown

Pay special attention to ‘be’ which has more changes when used in a sentence.
要特别注意 be，它在句中使用时会有更多的变化。

We use these verb changes to form tenses which talk about:
我们通过这些动词的变化来形成时态以表示：

✤ TIME (past, present, future)
时间（过去、现在、将来）
✤ ASPECTS of an action (repetitive, completed, ongoing)
动作的状态（重复的、完成的、持续的）
