OG 11-007 关于that引导限定性定语从句的问题

7.Carnivorous mammals can endure what would otherwise be lethal levels of body heat because they have a heat-exchange network which kept the brain from getting too hot.


which kept
that keeps

which has kept

that has been keeping having kept

Idiom + Verb form

The two underlined words contain two separate errors. The pronoun which introduces nonrestrictive clauses, which include information relevant but not critical to an understanding of the sentence. The pronoun that introduces a restrictive clause, which is critical to understanding the sentence because the clause defines its antecedent. Here, the clause following which defines heat-exchange network, so that must be used in place of which. The use of the past tense (kept) is incorrect because a current situation is discussed; the present tense (keeps) is consistent with the other verbs in the sentence.

A Which is incorrectly used for a clause that defines; kept is the wrong tense

B Correct. That introduces a restrictive clause; keeps indicates a current situation and is consistent with the other verbs in the sentence.

C Which incorrectly introduces a restrictive clause; has kept is the wrong tense

D The complete sentence is written in the present tense; there is no reason to switch tenses in the restrictive clause

E Having is awkward and imprecise; kept is the incorrect tense

The correct answer is B.



XDF老师讲的是which可以既可以引导限定性定语从句，也可以引导非限定性定语从句，只是有没有逗号的问题。

但是，这里却说：“which只能引导非限定性定语从句，而限定性定语从句需要用that引导。”
 请问引号中的话能不能作为GMAT语法的规定，还是这里只是特殊情况。

还有啊，本人找不到关于that引导定语从句的帖子，请看到的XDJM发个链接给我吧，谢谢啦·····

限制性定语从句that最好了，虽然Which也可以用，但在很多情况比如有情态动词的情况下，只能用那that. 因此，在没有别的区别的情况下，选that比which好，至于帖子，google一下，有很讲解的

楼上说的对啊。。。限制性定语从句that可以指代的范围最广，超过which和who，几乎是万用的

这题的话觉得一个keeps就出来了。。不知道这么想对不对。。求NN解答

谢谢大家的解答!
找到了that和which不可替代的情况，贴出来希望对存在同样疑惑的G友们有所帮助

关系代词that和which在很多情况下可以互换,但是下面情况只能用that：
1 先行词为不定代词everything，little, much，all，anything，nothing。

2 先行词前有形容词最高级、序数词修饰时，用that。

3 先行词被 all, any ,no ,little, much, some ,every修饰时

４先行词被the only，the very，the last 修饰时，用that。

5 先行词同时指人和指物时，用that。

6 当先行词为数词时,用that。

7 当先行词前面有who, which等疑问代词时,用that。

8 主句是There be结构，修饰其主语的定语从句宜用that作关系代词。
