◆警示 一般情况下,同位语从句紧跟在它所说明 的名词的后面,可是有的时候,为了表达 的需要,名词与从句之间被另外一些内容 分隔开了,叫做“分隔同位语从句”。对 于这类同位语从句,一定要根据句意,找 准它所说明的名词。
2.定语从句与状语从句 请看两组句子: 第一组:区分such...as...和such...that... (1)The new storybook is written in such easy English as beginners can understand. (2)The new storybook is written in such easy English that beginners can understand it.
【2012福建卷】35. We promise attends the party a chance to have a photo taken with the movie star. A. who B. whom C. whoever D. whomever 【考点】本句考查连词的辨析 【答案】C 【解析】首先本句考查的关键短语是promise sb sth“向某人承诺某事“本句指的是向参加聚会的 人提供一个和电影明星合影的机会,不定式做 chance的定语,然后就是参加聚会的任何人 whoever=anyone who,这样句子就很清晰了, 所以划分句子成分非常关键,以前考察whoever
◆辨析 判断是定语从句还是同位语从句可以用 “加词”的方法,即在名词和从句之间加 入一个be动词,如果句子意思成立,则是 同位语从句,否则,则是定语从句。如上 面第二句,加上be动词后: The news is that our team has won.句子 意思成立,所以是同位语从句。而第一句, 加上be动词后: The news is that he told us.意思不成立, 因此不是同位语从句。
