英语疑问
为什么在一些时间状语前不加介词：
如：I finished my homework 5 minutes ago.这里5 minutes ago前面没有介词,而且ago也仅仅是个副词,能这么用吗?
另外还有：When he arrived there that morning, he became very happy. 这里that morning前面为什么不要in或者on之类的介词?是省略?

这是英语中以比较常见的习惯用法,finish my homework 后面的成分显然是状语,也就是副词结构,5 minutes ago单独使用起到一个副词的作用,可以这么用
arrive 是不及物动词,后面可以加in/at+ noun.然后还可以加状语,there 在这里是副词, that morning 单独使用也可以做副词
见多了就好了:)

英语疑问为什么在一些时间状语前不加介词：如：I finished my homework 5 minutes ago.这 I finished my homework an hour ago(改为现在完成时) I have finished my homework.可否这么说 I finished my homework.为什么英语变句,I finished my homework last night.（强调时间）怎么变? I have finished my homework 用how long对i finished my homework two hours ago I have finished my homework two hours ago.哪里错了英语1.i finished my homework《改为一般疑问句》 ten minutes ago为什么不加介词 i found my homework ___ a.twenty minutes ago b.in twenty min I have finished my homework now这句话语法分析 ( ) you( ) your homework?yes,I finished it an hour ago.
