关于非谓语动词,DONE和DONE的区别,比如说这句话:Never lost faith in himself,the scientist was determined to carry on with the research,no matter what others said.如果改成:Having never lost faith in himself,the scientist was determin
关于非谓语动词,DONE和DONE的区别,
比如说这句话:
Never lost faith in himself,the scientist was determined to carry on with the research,no matter what others said.
如果改成:
Having never lost faith in himself,the scientist was determined to carry on with the research,no matter what others said.
这两句话在语法和意思上有什么差别?因为明天有一个竞赛,主要考非谓语动词和从句,所以来问,

Having done 是完成时,若放在句首有主动的含义,而 done 放句首一般表示被动含义.
比如:Having used it,I put it on the desk.此举意思表示:用完它以后,我就把它放在捉上了.其中我用这个东西,是主动,所以应该用-ing形式.但是如果:used too much,it fade its colour.此时,used 就是修饰it,因为it是被用的,表示被动.
一般情况下,Having done 表示主动含义,而done 表示被动含义.

第一句 是错的!!!!!!!!!!!!!!!!!!!!
