现在英语的发展趋向于简洁,介词的省略是其表现之一,尤其在口语中更为常见。省略的原则是以不损害句意为前提。几个常用介词的省略情况如下:1、at 的省略在用作时间或地点状语的短语中,如果名词前有 some,any,every,this,all,the same,what 等限定词,一般省略 at。例如:You can come any time.你任何时候来都可以。What time will you start?你何时动身?It was quite light and any moment now the sun would rise.天已经很亮了,太阳马上就要出来。 Now the development of English tends to be concise, the omission of prepositions is one of its manifestations, especially in spoken English. The principle of omission is premised on not prejudicing the meaning of sentences. The omission of a few commonly used prepositions are as follows: 1, at the omission of phrases used in time or place adverbial, if the noun preceded by some, any, every, this, all, the same, what and other qualifiers, generally omitted at . For example: You can come any time. You can come anytime. It was quite light and any moment now the sun would rise. It was very bright and the sun was coming out soon.
