标题: 求教OG 13 SC 012 [打印本页] 作者: Grace080410 时间: 2013-1-25 22:29 标题: 求教OG 13 SC 012 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. (A) which kept (B) that keeps (C) which has kept (D) that has been keeping (E) having kept 解释说In (A) and (C), which introduces a restrictive clause. Some writers follow the convention that which can only be used for nonrestrictive clauses, but insistence on this rule is controversial。我不懂的是这里的意思是说一些作者认为which只能引导非限制行从句，但我们以前学的不是which可以引导从句什么的吗？作者: DesmondWang 时间: 2013-1-26 14:22
以前学的东西我建议你不要用在GMAT上，GMAC有它自己的rule，我们遵从它的就OK了，毕竟它才是是出题的人。有些其他语法书上正确的point在GMAT就是不适用。 一般GMAT偏好comma+which，我还没看到过不加comma直接用which作为正确答案的。（如果有希望能够列出，让我也学习一下，万谢！）作者: Annabellez 时间: 2013-1-26 16:55
which只用在下列情况： 1、介词+which（介词+that是不对的，除了in that=because） 2、N，which GMAT貌似不大喜欢which，除了介词与“，”，其他一律用that吧 比如说which与that同出现同正确时用that准确率更高作者: Annabellez 时间: 2013-1-26 16:57
介词+which（on/in/through...+which）是可以的，比where表达更准确作者: Grace080410 时间: 2013-1-26 19:00
