广东高中英语语法填空 关于that 和which的关系

Oceanigraphy is a branch of science (that) studies the oceam’s physical featurea and creatures in it.
The wars of the ROSES were battles (that) were fought between the supporters of the HOUSE of Lancoster and the supporters of the HOUSE of York
为什么要使用that 而不能使用which

在这两个句子里that 后面都是同位语从句 是对前面解释说明的 所以用that 。
而which 是在这里是限制性定语从句 是修饰一个词或整个句子 但不可以省略。

1. 表示像...一样，like后面接短语或名词；as后面接句子；另外它们两个的侧重点不同，like侧重于不同事物的比较，her performances like a monkey.她的表演像只猴子。而as侧重于同类事物的比较，this car is beautiful as that one. 这辆车和那辆车一样漂亮。 2.as可以作为关系代词或关系副词引导定语从句，在从句中一般作主语或宾语“正如”：as we said, it rained last night. 正如我们说的那样，昨晚真的下雨了。（宾语）that was his outstanding benifit,as has been said before.那就是他最显著的优点，正如之前所说的那样。 3. 还有一些就是as的固定搭配：as far as i am concerned, 就我个人而言，as we know，正如我们所知道的，等等一些固定用法。

这是定语从句 绝不可能是同位语从句。同位语从句的that是不能充当句子成分的。而这两个句子中的that是定语从句中的主语。 我认为用which完全可以。

that和which做比较，主要在于它们在定语从句中的用法 that 和which在定语从句中都是做关系代词，指代先行词是事物的名词或代词（that还可以指代人，which 不可以）。通常情况下二者可以互换。 区别： 关系代词用that（不用which）的情况： 1. 先行词是all, anything, everything, nothing等,关系代词应用that That's all that he told me. 2.先行词前有the only, the same, the very 或no, little, much, any, every, all 等修饰时,关系代词应用that She is the only person that I know in this company. 3. 先行词前有序数词或形容词最高级修饰时,关系代词常用that The first thing that I want to do is to take it away. 4. 当先行词同时含有"人"或"物"时,关系代词应用that 5. 在固定结构the same...that...; so...that...; such...that...以及it is/was...that...的强调句型中,要用that This is the same park that we once visited. 6. 如主句以there be开头时,关系代词应用that There is a room that has two windows. 关系代词用which（不用that）的情况： 1. 非限制性定语从句中关系代词一般要用which She won the competition, which made the whole family very happy. 2. 关系代词前如有介词,关系代词须用 which; 如把介词移至句末,可用that(或省略) There’s only one problem about which they disagree. This is the key (that) she was looking for. 3. 如果先行词是that,关系代词应用 which I know that which you told me. 4. 如先行词和定语从句之间被其它较长的成分分隔,常用which Larry told her the story of the young airman which I narrated at the beginning of this book. (先行词为story) 5. 在"those+复数形式的名词"结构中,其后的关系代词多用which A shop should keep a stock of those goods which sell best. 6. 一个句子中如有两个定语从句,第一个定语从句用了关系代词that,第二个从句中的关系代词宜用which;但在平行结构中,应重复同一个关系代词 This is the book that you bought which you have lost. I have a house which is located on the hillside, which faces the south. 此外，that还可引导同位语从句,which不能 I have heard the news that they had won the game.
