语法白痴弱弱的问2道OG题！ - ChaseDream

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.

解释里面有一段话说"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. "

我想问一下，which不是也可以引导限制性定语从句嘛？为什么这里一定要that替换which啊？难道如果有which keeps就不选这项么？

另外，在另一道题的解释中说，非限制性定语从句中关系代词which要immediately follow its referent，是这样的么？

which 可以引导限定性定语从句，在og后面的例子里会见到。which keeps 也对

限定性或非限定性引导词需紧跟其修饰的引导词，绝大部分情况不允许跳跃，但是如 a of b that that clause 也可能修饰 a 非 b, 但可以通过从句中的动词的单复数形式判断修饰对象。极少数题里也出现了 a, + 介词结构, + which clause 从句跳过了介词结构修饰了 a

P.S:songlovegt你太好了~~我发现大家很多人都是上来问问题，除了版主很少有人愿意答问题的……

13.As Hurricane Hugo approached the Atlantic coast, it increased dramatically in strength, becoming the tenth most intense hurricane to hit the United States mainland in the twentieth century and most intense since Camille in 1969.

(A) most intense since Camille in 1969

(B) most intense after Camille in 1969

(D) the most intense after 1969, which had Camille

(E) since 1969 and Camille, the most intense

解释里面说“Because tenth appears between the and most intense in the first phrase, the must be repeated in the second phrase: the most intense.”但是解释又接着说“ While in some constructions, such as the most frightening and most intense, the would be understood and so would not need to be repeated, the definite article the is required in this superlative form construction. ”

于是我就不明白了什么时候可以省略the,什么时候不可以省略呢？为什么这个题中前面有个the tenth most所以后面就必须是the most intense，是跟那个序数词有关么？另外，the most frightening and most intense这句既然第二个the都省略了，可不可以省略第二个most呢？

An inventory equal to 90 days sales is as much as even the strongest businesses carry, and then only as a way to anticipate higher prices or ensure against shortages.

这句话什么意思啊？？？怎么分析句子结构啊？

To use "which + clause", you are gonna need a comma right before which, such as" ,which"
