知识要点

　　动词表示人或事物的动作或状态。

　　根据其在句中的功能，动词可分为四类，分别是实义动词(指某个具体的静态如：think, love 等或动态如：run, walk 等)、系动词(常用的是be, feel, get, look, taste等)、助动词(常用的是do, does, did等用来构成否定句及疑问句)、情态动词(常用的有can, may, must, shall, should等，情态动词后一定要跟动词原形)。

　　1) 动词的基本形式

　　绝大多数动词都有五种基本形式：动词原形、一般现在时第三人称单数、现在分词、过去式和过去分词。

　　A. 第三人称单数形式的构成

　　一般现在时主语是第三人称单数时，谓语动词后要加s或es，其变化规则与名词变复数的方法大体相同：

　　1. 一般情况下只在动词后加s，如work-works, write-writes.

　　2. 以o,s, x, sh, ch结尾的动词，后加es，如guess-guesses, mix-mixes,

　　finish-finishes, catch-catches.

　　3. 以辅音字母加y结尾的动词，改y为i加es，如study-studies.

　　注：不规则变化的有have-has

　　B. 现在分词的构成

　　1. 一般情况下在动词后加ing，如study-studying, work-working.

　　2. 以不发音的字母e结尾的动词，先去掉e再加ing，如write-writing,

　　move-moving.

　　3. 以一个元音字母和一个辅音结尾的重读音节结尾的动词，要双写末尾一个辅音字母，再加ing，如get-getting, begin-beginning.

　　4. 以ie结尾的名词，一般将ie改为y，再加ing，如lie-lying, die-dying, tie-tying.

　　C. 过去式和过去分词的构成

　　1. 一般情况直接加ed，如ask-asked, work-worked.

　　2. 以不发音的e结尾，只加d，如love-loved, dance-danced.

　　3. 以辅音字母加y结尾，把y变为i加ed，如try-tried, study-studied.

　　4. 以一个元音字母和一个辅音结尾的重读音节结尾的动词，先双写末尾一个字母，再加ed，如stop-stopped.
