小升初英语基本语法与练习五动词
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.
