A.the detail of which B.which of the detail
C.and the detail D.the detail of it

答案是B，可我选了A
不知道错在哪里，而且这类题经常错，郁闷

Answer 1

答：题目本身有误，先订正如下：
模块一定语从句精讲精练与分类练习._百度文库
They have started an investigation, ______are being kept secret.
A. the details of which B. which details
C. the details D. the details of that

这是从非限制性定语从句的谓语动词中有are判断出来的，detail应该是复数形式。
定语从句，实质上就是由一个句子，通过关系词变成一个从句而来的。解这样的题目的一个方法就是想办法还原--还原成原来的句子。
这一句话原来是由两个句子变来的。这两个句子是：
1. They have started an investigation.
2. The details of the investiation are being kept secret.
现在将第二句变成一个非限制性定语从句，将the investigation变成which, 有二种方法：
1. They have started an investigation, the details of which are being kept secret.
2. They have started an investigation, of which the details are being kept secret.
另外还可能用关系代词whose表法所属关系，还有第三种方法：
3. They have started an investigation, whose details are being kept secret.
译：他们已经开始了调查，其细节在保密之中。

Answer 2

答案就是A .the details of which = of which the details = whose details
选项B 是错误的

Answer 3

A.这个定语从句中的引导词which指代的是investigation。这样你可以把investigation带入到which中看看那个定语从句改成的句子是正常的。这样的就是正确答案。
比如A改变后就是.the detail of investigation are being kept secret。这是正确的语序。其他的都不行。

Answer 4

你要是选A的话完全别有必要要of which

Answer 5

如果语法经常不懂或不会，在高三阶段，最好的应试方法是多读，一到类似的题就会顺嘴读出并写出来 我是过来人 ，相信我，英语语法如果闹不清，除了记忆语法，多读便是另一个笨的好办法

Answer 6

打错了吧，后面的是are ,前面得有复数啊。the details of which are being kept secret.

Answer 7

非限定性定语从句呀，which引导的从句修饰investigation,而不是detail
