on Doing

1、on /upon doing sth 刚一做某事(就) 结构:介词+动名词 功能:相当于as soon as引导的时间状语从句。 例如: On arriving at the village,these college students went to help the farmers with their work. =As soon as they arrived at ...

可以根据语义,基本可以通用,但是不是等于的关系,on/upon doing sth 这个句型能转换成when引导的时间状语从句,所以翻译成 "当...时候"。 upon/on doing =as soon as 又如:1、I'll tell him about it upon/on seeing him. 2、On/upon arrivin...

spend的主语必须是人,常用于以下结构: (1) spend time /money on sth. 在……上花费时间(金钱)。 例: I spent two hours on this maths problem. 这道数学题花了我两个小时。 (2) spend time / money (in) doing sth. 花费时间(金钱)做某事。...

切记,on doing这个固定结构是表示”一....就....”,跟”as soon as”完全同一个意思!!(1)也可以说成On seeing it,the woman said she did not like it. 除了(2)和(3)之外的句子考察的都是”分词表伴随”这个用法.注意,分词并不是简单的doin...

一…就go on (doing)继续;继承go on(doing)继续做某事keep (on) doing继续做;反复不断地做某事keep on (doing)继续go on doing sth.继续做keep on doing sth.不断work on (doing) sth.从事Keep on (doing sth.)继续做某事keep (on) doing sth.继续

keep doing坚持做某事 强调状语的继续,常与表示延续动作的动词与静止状态的动词连用,如(hope,think,wonder,dream,sit,stand,lie,sleep等) He kept talking until the meeting was over.他一直在说,直到会议结束. He kept eating/ smiling/ walki...

dong sth.on是介词,所以+doing,或者说 concentrate on sth。

go on to do sth.;go on doing sth.;go on with sth. 这三个短语都有继续做某事的意思,但在含义上有所不同。 (1) go on to do sth. 表示“接着做另一件事”,即接下去做与原来不同的一件事; (2) go on doing sth.表示“继续不停地做某事或间断...
