7. Dr. Hakuta's research among Hispanic children in the United States indicates that the more the children use both Spanish and English, the greater their intellectual advantage in skills underlying reading ability and nonverbal logic. 請問畫線部份是屬於哪種從句阿?
the more...the more...结构其实是一个从句+主句的结构:
1. 第一个the more...相当于一个原因状语从句, 是从省略了表示原因的连词as等进化而来的(也可理解成是省略了if的条件状语从句); 第二个the more...引导的是主句.
eg.As a mammal's skin is thicker(从句), it has less hair(主句). 转换为:
The thicker a mammal's skin is(从句), , the less hair it has(主句).
2.两个the都是副词(而非冠词), 表示程度并修饰后面的形容词比较级. (前后两个the的意思在 韦氏字典解为: the: adv. 2 a : to what extent b : to that extent )
the more...the more...结构的三个原则(参自[托福语法填空要点])
1. the more后面的名词必须使用冠词或所有格.
如本题的the more the children..., the greater their ...
2. 后面的谓语如果是be动词的话, 可以省略, 这一点对于前后两个都适用. (特别当主谓语时it is时, 常同时省略.)
eg.What size box do you want?---The bigger, the better. 就是的The bigger it is, the better it is的省略结构. 上面的252题the greater...引出的主句显然省略了Be动词is, 表语是greater, 提到句首加副词the表示程度, 构成并列的
上面的252题如果要补出谓语的话, the greater is...结构较好. 但是Official GuideD的解释是:The phrase [the more the children] should be completed by a parallel phrase that begins with a comparative adjective and a noun phrase, as in [the greater their...] advantage. Only C correctly completes the structure with a parallel phrase.
所以省略了is后的the greater+名词短语更平行和简洁.
