下面本文整理了which有关的GMAT语法知识解析，希望可以给大家参考。
which的用法
1、WHICH非限
1.which指代主句宾语：s+verb+o,which指代0(svo,which指代s一定错!)
2.which指代主句主语s:s+verb,which
(1)介词+which=连词
1.s+verb(+o)+prep+which
2.s+verb(+o),prep+which
区别介词+that=名词
I will buy this book because from that I study a lot.(有because作为连接词，不用“介词+which”结构连接)
I will buy this book from which I study a lot.(无连接词，需要用“介词+which”结构连接)
which指代的三种情况：
1、紧邻修饰
一般情况下，“名词，which”中的which是就近修饰紧邻的名词的。这种例子多的不胜枚举。
一般例子就不用举了，只举个比较特别例子“A of B, which”(注：这里的of表示从属关系)
1，The commission proposed that funding for development of the park, which could be open to the public early next year, be obtained through a local bond issue.
2,Construction of the Roman Colosseum, which was officially known as the Flavian Amphitheater, began in A.D.69, during the reign of Vespasian, and was completed the Colosseum with a one-hundred-day cycle of religious pageants, gladitorial games, and spectacles.
Flavian Amphitheatre：福雷维安圆形剧场
3，In laboratory rats, a low dose of aspirin usually suffices to block production of thromboxane, a substance that promotes blood clotting, but does not seriously interfere with the production of prostacyclin, which prevents clotting.
thromboxane [生化]凝血噁烷，凝栓质，血栓素。阿斯匹林可以阻止血小板生成凝血恶烷
prostacyclin n.【生物化学、药物】环前列腺素，前列腺环素,
4，The survival of coral colonies, which are composed of innumerable tiny polyps living in a symbiotic relationship with brilliantly colored algae, is being threatened, experts say, not only by pollutants such as agricultural runoff, oil slicks, and trash, but also by dropped anchors, probing divers, and global warming.
5，In attempting to solve the problems caused by a lowering of the price of oil, oil companies operating in the North Sea have taken a variety of approaches, which include reducing employment, using new technology to pump oil more efficiently from smaller fields, and finding innovative ways to cut the cost of building and operating platforms.,
这些例子都能说明从属关系“A of B，which”中的which就近修饰紧邻的名词B。但是需要注意的是，在“SVO,which”句型中，如果which指代S一定错误，which如果指代主语，这样使用:s+verb,which
