动词的分类
动词按其在句中所充当的句子成分分为谓语动词和非谓语动词
一.谓语动词: 用于谓语中的动词称为谓语动词. 按照其能否独立作谓语, 谓语动词又可分为两类:
1.能独立作谓语的动词称为完全动词, 即实义动词;
2.不能独立作谓语的动词称为不完全动词, 包括: 连系动词, 情态动词, 助动词
连系动词有两种: ①.表示特征状态, 如: be, appear看起来, seem看来,似乎, look看起来, sound听起来, smell闻起来, taste尝起来, feel 摸起来, remain仍然是; ②.表示变化过程, 如: become变成, get成为, grow变得, turn变成, go变得, prove证明是
情态动词和助动词参看其他章节
二.非谓语动词: 不充当谓语的动词形式称为非谓语动词, 包括: 不定式, 分词(现在分词和过去分词), 动名词三种, 它们在句中可以充当主语, 宾语, 表语, 定语, 状语等, 具体细节参看第十一章.
三.使用实义动词时要注意的问题:
1.实义动词分为及物与不及物, 及物动词要求有宾语, 能用于被动语态; 不及物动词不能有宾语, 不能用于被动语态
2.实义动词还可分为持续动词与瞬间动词, 前者可以与表示段时间的时间状语连用, 而后者不可. 但瞬间动词的否定式表示该动作没有发生, 可视为一种可持续的状态, 并可与段时间状语连用
a. They watched the train leave for five minutes. ( watch是持续动词)
b. I received his letter yesterday. ( receive是瞬间动词)
c. How long have you joined the army ?(错误: joined是瞬间动词, 不能与段时间how long连用)
d. When did you join the army ? (正确)
e. How long have you been in the army ? (正确)
f. How long may I borrow the book ? (错误: borrow是瞬间动词, 不能与段时间how long连用)
g. How long may I keep the book ? (正确)
h. I havent received his letter for almost two months. (not receive表示没有收到, 这一意思可视为一种持续的状态, 因此可以和段时间two months连用)
四.短语动词的种类: 共有五种不同的短语动词
1. 动词+介词: 相当于一个及物动词, 如: depend on, look for
2. 动词+副词: 有的相当于及物动词, 如: look up(查找), 有的相当于不及物动词, 如: slow down(慢下来). 这类短语动词的宾语是代词时, 只能放在动词和副词之间, 如: call her up; 这类短语动词的宾语是名词时, 既可放在动词和副词之间, 也可放在副词之后, 如: call Tom up或call up Tom
3. 动词+副词+介词: 相当于一个及物动词, 如: keep away from
4. 动词+名词+介词: 相当于一个及物动词, 如: lose sight of
5. be +形容词+介词: 相当于一个及物动词, 如: be worthy of
