SAT语法整理是备考的必经之路,下面我们就来讲讲SAT语法非限制性定语从句。
SAT语法提分先搞定SAT语法定语从句!
SAT语法整理之非限制性定语从句:
首先普及一个语法常识,定语从句分为两类:限制性定语从句和非限制性定语从句。 他们的外表特征就是逗号的存在。 简言之,非限制性定语从句就是在从句和主句之间加了一个逗号,读时有停顿,译时分两句。你以为这些就是非限制性定语从句了吗? Naive!
大家来看看这组例句:
Sentence 1: There are three students who listen to the music.
Sentence 2: There are three students, who listen to the music.
大家看完例句来回答问题:
According to sentence 1, how many students are there? (unknown)
According to sentence 2, how many students are there? (three)
通过对比以上一对句子,我们可以看出差别,限制性定语从句(不带逗号)是对先行词students起到修饰和限定的作用,不可或缺。简言之,不知道到底有多少学生在,但是学生分两类,一类听音乐,一类不听音乐;非限制性定语从句(带逗号)是对先行词students进行信息补充,可有可无,在非限制性定语这个句子中,只有三个学生存在。
再来看看这题,看看自己以前是不是学了假的非限制性定语从句!
题目: Since his career which ended in the mid-twentieth century, Freud has remained a common cultural and scientific reference point.
A. NO CHANGE
B. Since his career, which ended in the mid-twentieth century, Freud has remained
C. Since his career which ended in the mid-twentieth century; Freud has remained
D. Since his career ( ended in the mid-twentieth century)Freud has remained
我们这道题中,同学们肯定纠结在AB两个选项之中,面对逗号,一脸茫然。
我们根据之前所讲的限制性和非限制性的特点,那么A选项就将career分为了两类,一类是在二十世纪中期结束的,一类不是。请问同学们,这么划分一个人的career合适吗? 再对比B选项,非限制性定语从句,没有对career进行分类,只对其补充更多信息。所以这里我们应该使用非限制性定语从句最恰当,最合理。
以上就是小编为大家分享的SAT语法定语从句系列,希望对大家的备考有所帮助。
