who did this expriment was mr liu
这句话确实有问题
正确应为
The one who did this experiment was Mr Liu.
改了三处地方,加了主语、实验补了一个字母、专有名词刘先生首字母放大.
最准确,有问题追问,祝好!
【来自英语牛人团】
再问：为什么呢，我那句从语法角度讲也是正确的吧
再答： who did this experiment 是个定语从句，前面是必须要有主语的，就是说加个“The person / The one” 就可以了，表示做了……的人其他两处虽然不是语法错误，但也算硬伤了所以按我的改就对了。满意请及时采纳，有问题随时问我。祝好！
再问： who did this experiment is unknown这句话怎么是对的
再答：那这里它就是名词性从句，不过最好还是It is still unknown who did this experiment. 避免句子头重脚轻
再问：为什么之前那句不能看作名词性从句呢
再答：后一句话是那么翻译的：是谁做了实验还是个谜。前一句话就不能翻译成：谁做了实验是刘先生，而是那个做了实验的人是刘先生看出来了吗？who在前一句里是表示实在意义的，后一句是引领从句修饰那个人的
再问：那比如，我要翻译他做这实验的原因不为人知和他做这实验的原因是因为他想发现什么东西
再问： why he did this exp is unknown
再问： the reason why he did exp is that he want to find sth
再问：我这2个翻译正确吗
再答： the reason why……那个对一些 want 改成wanted 【例句】 The reason why he did not come is unknown. 他没来的原因不清楚。

To find who did this is important 这句话的结构是不是主系表吖 who was this man?who is this man?这2句话一样吗? ---hello,is this Mr.liu speaking?----(yes,who is that?that怎么 Who did we address this bill to?Ms. Chen?这句话什么意思? I was late again this morning,so Mr.Lee was very( ). Bob did who did you talk with?这句话who是什么的宾语 who--this book--?Adid,written B was,used C did,written D was who it was invented by?这句话是错的怎么改为什么啊 who is the man over there?Is it Mr.liu? Who will receive this postcard?这句话的意思 Mr Li.is a very rich man who lives alone .这句话是宾语从句吗? who did you think was the best act这是一个什么句子?was the best act
