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。...

spend 花费 它的用法是: 1 主语(人)+ spend +时间/金钱+( in ) doing sth {IN 可省略} 或 2 主语(人)+ spend +时间/金钱+ on sth 意思是“ 某人花费……做……” 这两种句型是同义句,可互换。 如 He spent one hour doing his homework yesterda...

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

spend有spend ... on sth / (in)doing sth两种结构, spend ... on sth,on是介词; 在……上花费时间(金钱)。 spend ...(in)doing sth,花费时间(金钱)做某事,in可以省略。 也有spend... on doing sth的用法,比较少见。

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

Upon/on registering/registration, you must fill out the form. 【注册时,你必须填写表格。】 显然“注册”的主语是“你”,也就是和后半句的主语是一致的。 同义句:You must fill out the form as soon as you register. 主句和分句的主语也依...

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...
