介词是表示词语之间语义关系的词类。介词与其后的名词短语一一“对号入座”对词语的搭配关系更是至关重要。但是在有些情况下,有些介词是可以省略的,有些甚至必须省略。 1. 表示时间的短语中有next,last,one,this,every,each,some,any,all等单词时,省略介词: Can you go to school next Monday?下周一你能上学吗? We moved here last year. 我们去年搬到这儿。 You can come any day from Monday to Friday.周一至周五你哪一天来都行。 We have worked all day. 我们已经干了一整天活。 2. today, yesterday, tomorrow, the day before yesterday, the day after tomorrow前,无介词: It is sunny today. 今天阳光灿烂。 We will go to Beijing tomorrow. 我们明天去北京。 3. 在不定冠词a/an的短语中:three meals a day 一日三餐 4. what time前的at常省: (At)what time would she come here?她几点钟到这儿? 5. 在last, wait, live, stay等延续动词后,for可省: I waited several hours and then he finally came. 我等了好几个小时后,他才到。 6. Wh-引导的名词性从句作介词宾语时,前面介词可省: The little boy had no idea (of) what to do next. 这个小男孩不知道接下来要做什么。 |
