英文选词填空This new NSF network attracted more and more institutional users,many of ___ had their own internal networks.a which b them 为什么不能选them?
因为这是一句话,选which说明逗号后面的句子是users的定语从句.如果用them,那就是两个句子,many前面必须有一个引导并列关系的连词and,原句中没有and,只能做为从句.所以选which.
非限制性定语从句,which引导,用来说明前面整个句子的情况或主句的某一部分
which是指代前面句子中距离分句最近的institute users。them的他们旨意没有which明确。而且通常在这样的复合句子当中,都选which指代前文的内容。
This new NSF network attracted more and more institutional users 这个句子是个完整句,如果选them,那么后面一个句子也是一个完整句,两个句子直接必须有连接词,加一个and就可以了; 选which是使后面一个句子成为定语从句,which指的就是users。
选which。因为users后用的是逗号,前后两句之间没有连词,结构不完整,必须选择可以起连接作用的词,故用which来引导一个非限制性定语从句。值得一提的是,若users后用的是分号或句号,或者users后有连词and,就吸能用them了。
这里是由which 引导的定语从句
而且them是宾语用在这里就出现了语法错误
后面跟的是which从句。which代表的是institutional users。
