所谓及物动词，就是谓语动词（predicative verb），不必通过介词引荐宾语。
相反的，不及物动词（intransitive verb）是不带宾语的。
有许多动词，虽然性质是及物的，但不一定要有宾语，如下列的①a和②a便是这种情形：①a. We study every day.①a. We study every day.b. Do you study English every day.②a. Please write clearly next time.b. Can you write your composition now?如果本质上就是不及物动词，就不会有宾语；若要宾语，就要借介词之助，一起连用才行(不及物动词+宾语+介词)，如③b和④b;③a和④a是错的；*③a. The children are listening the music.b. The children are listening to the music.*④a. She is laughing the crippled man.b. She is laughing at the crippled man.反之，及物动词不必靠介词，就可以带宾语，如上述的①b和②b ，又如⑤和⑥：⑤John is giving a book to me.⑥Who will answer this question?如果无意中把介词加上，就错了，如：*⑦Who will answer to this question?下列这句从房地产广告中看到的句子，也犯了同样的错：“We have many buyers awaiting for available units here.”“Awaiting”是个及物动词，后面的介词“for”是多余的，要去掉；不然把“awaiting”改为“waiting for”也行。
许多人习惯上喜欢把介词加到及物动词后面，然后才带出宾语。
最常见的是“emphasize/stress on/upon”和“discuss about”，如：⑧Singaporeans seem to have emphasized on material gains.⑨In our education system, we stress upon examination results.⑩World leaders spent a lot of time discussing about worsening economic problems.显然的，这三句里的介词“on/upon”和“about”是多余的，不必要的。
下面是些类似的错误：●The young must obey to their elders.●Do not approach to that odd-looking man.●The audience attacked on the rude speaker.●Nothing can escape from his parents' eyes.●Do you hope to serve for your nation?●When did Susan marry with Paul?介词“to, on, from, for, with”都要去掉才对。
为什么会有这些错误呢？主因是分不清楚及物动词和不及物动词的性质。
其次，就是对同一个动词及其名词的句型有些混淆。
解决之道有二。
第一，要把“及物动词＋宾语”和“不及物动词＋介词＋宾语”划分清楚，如：I did not answer him./ I did not reply to him.He reached Londan yesterday./ He arrived in London yesterday.第二，把及物动词转化为名词，然后加上适当的介词和宾语，如：Don't approach such a person.Is oral practice a good approach to language teaching?when, while, as的用法区别三者可表示“当……时候”，区别如下：(1)若主句表示的是一个短暂性动作，从句表示的是一个持续性动作，三者都可用：He fell asleep when [while, as] he was reading. 他看书时睡着了。
【注】as 用于引出一个持续性动词表示“在……期间”时，其谓语通常只能是那些含有动作(action)和发展(development) 意味的动词，一般不能是那些不用于进行时态的动词(如be, seem, love, want, agree, see, know, have 等)，所以下面一句中的while 不能换为as：A：I’m going to the post office. 我要去邮局。
B：While you’re there, can you get me some stamps? 当你在邮局时，能帮我买几张邮票吗?(2)若主、从句表示两个同时进行的持续性动作，且强调主句表示的动作延续到从句所指的整个时间，通常要用while：Don’t talk while you’re eating. 吃饭时不要说话。
I kept silent while he was writing. 在他写的时候，我默不作声。
但是，若主从句表示的两个同时进行的动作含有“一边…一边”之意思，通常用as：She sang as she went along. 她边走边唱。
(3)若从句是一个短暂性动作，主句是一个持续性动作，可用as / when 但不用while：It was raining hard when [as] we arrived. 我们到达时正下着大雨。
(4)若主从句表示的是两个同时(或几乎同时)发生的短暂性动作，用as / when：I thought of it just when [as] you opened your mouth. 就在你要说的时候，我也想到了。
(5)若要表示两个正在发展变化的情况，相当于汉语的“随着”，一般用as：Things are getting better and better as time goes on. 随着时间的推移，情况越来越好。
