非谓语中doing 和 having done的区别比如____in thought,he almost ran into the car in front of him 这里填LOST 而不是 having lost 而 ______his letter,i will write another letter to him 这里就要填having not received~

请问,在非谓语动词中doing和having done如何区分? 非谓语做定语时,having done,和doing有什么区别?如果是在过去式中用having done还是doing？ 非谓语动词中,现在分词和动名词有什么区别?什么时候用having done? 在非谓语题目中,having been done 和done 的区别是什么啊? doing 和 be doing 哪个算非谓语?非谓语都包括哪些形式呢? having done 与done在非谓语动词中区别 是不是非谓语中,如果完成式表示非谓语部分,必须把have改成having... to be doing为什么不能非谓语动词作主语还有to having done 非谓语动词中什么时候用不定式,什么时候用分词,什么时候用动名词?不是区分to do,to be doing,to have done ,to be done ,to have been done!而是选项中同时出现to be doing和doing或to have done和having done或to have 非谓语中doing 和 having done的区别比如____in thought,he almost ran into the car in front of him 这里填LOST 而不是 having lost 而 ______his letter,i will write another letter to him 这里就要填having not received~ 非谓语中to be done =doing?非谓语中to be done =doing?=done 非谓语动词doing的被动形式和非谓语动词done的区别 英语非谓语动词中有having been done,那有没having done形式? ——several times,they need some encouragementa.failedb.having failed在非谓语中done 和having done 有什么区别 I remember having seen her in a cafe中的having seen是不是非谓语动词?1.这个句子的完整形式是I remember that I having seen her in a cafe “having seen”在从句中是非谓语动词吗?2.这个句子是不是用的remember doing keep是不是在非谓语动词中有keep sb done 和keep sb doing的用法 一道非谓语选择.You can't just stand by and see our country ____by some people.A attacking B attacked C having attacked D be attacked但为什么D不行,不是有see sb.do/doing? 英语中谓语动词和非谓语动词的区别?
