动词可以分为四类：行为动词（或称实义动词）、连系动词、情态动词以及助动词.今天主要说说行为动词的用法.
1. 不及物动词：不能直接跟宾语,常须加了介词后方能加宾语.
如：look at (for, after), get to (on), operate on, hear of, hear from, point to (at), worry about, knock at, play with, think about等.
2. 及物动词：后面必须跟宾语,意义才完整.
在及物动词 + 副词构成动副搭配时,代词放中间这一点同学们常易忘记,故应特别加以记忆.
如：turn on (√) turn on the radio (√) turn the radio on (√) turn on it (×) turn it on (√)
常见的动副搭配的词组有：put on, pick up, look up, wake up, try on, write down, move away, take away等.
3. 注意行为动词的几种变化形式：
原形 enjoy
第三人称单数 enjoys
过去式 enjoyed
过去分词 enjoyed
现在分词 enjoying
过去式,过去分词,同学们须熟记初中所学的不规则动词变化表.
现在分词的变化方法,一般是直接在动词后加ing,有几个特殊的可加以记忆：lie-lying, die-dying.
要双写的单词有：
一个m (swim-swimming)
一个g (dig-digging)
三个n (run-running, win-winning, begin-beginning)
三个p (stop-stopping, shop-shopping, drop-dropping)
还有六个t (sit-sitting, hit-hitting, get-getting, let-letting, put-putting, forget-forgetting)
同学们特别应注意forget, begin这种双音节单词.
另外,eat, wait这两个词不是重读闭音节,故不能双写加ing,这也是同学们易犯的错误.

5. 有些及物动词后可以跟双宾语即直接宾语（表物）和间接宾语（表人）,间接宾语通常位于直接宾语之前,若颠倒两者的位置,则通常在间接宾语前加一个介词（to或for）.

make sth. for sb. give sth. to sb.
mend sth. for sb. lend sth. to sb.
