您这个问题实际提得挺大的，我给您推荐一篇文章看看，就能理解清楚。及物动词和不及物动词在英语错误中，“及物动词＋介词＋宾语”（是常见的一种。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. 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，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： ⑤ John is giving a book to me. ⑥ Who will answer this question? 如果无意中把介词加上，就错了，如： ⑦ Who 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。 不及物动词是动词的一种形式，所谓不及物动词(vi.)就是所表示的动作本身意义完整，动词后面不（需要）带宾语。例如：Time flies.光阴似箭。 如果要带宾语，就需要后面接介词。例如：Please listen to the teacher carefully. 请注意听讲解。 及物动词(vt.)就是后面可以直接带宾语的动词。如果它不带宾语，其意义就不完整。例如：My mother cleans the kitchen every day.我妈妈每天打扫厨房。Please keep the room clean and tidy.请保持房间的整洁和干净。Sound travels slower than light.声音比光（速）要慢。 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： ⑧ Singaporeans seem to have emphasized on material gains. ⑨ In our education system, we stress upon examination results. ⑩ World 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?
