请问：几个英语句子
第一：These words are derived from chinese.这些词来源于汉语.derive...from 是源自,来自的意思.那为什么这句要用are derived?是被动吗?还是系表结构?不管哪个都觉得不对,我觉得直接说：these words derive from chinese.就行了.因为derive from 就是来源于的意思啊.比较看这个句子：he showed a point of view that is profoundly different and typicallly chinese,deriving from thousands of years of tradition.在这句中,deriving from 表伴随,又是主动形式了?那这个词组到底怎么用?
第二：the people lived 20 years ago didnot know the secret.(20年前的人们不知道这个秘密.）这句中,lived 20 years ago可以这么用吗?这算动词过去式做后置定语,还是英语从句省略who?
第三：he glanced at the paper clutched in his hand.这句中clutched是done的形式做定语吗?
第二个句子最后半句话是“定语从句省略who”？原文题写错了。

Answer 1

第一,derive from 这个词组的意识为“源于”,是因为derive这个词的意思为“得到”,因此我们可以说；I derived the pleasure from the reading.(我从阅读中得到乐趣).这个例子中derive 为及物动词,相当于“get”.所以当 derive的宾语变为被动语态的主语时,句子的谓语动词要由“derive from”变为“be derived from”.
第二,正确的可以写成：the people who lived here 20 years ago didn't know the secret.
第三,在这句话中,clutched 为过去分词作后置定语修饰paper.
