求英语语法解答1.More wild tigers have been seen in the forest aroun

1.More wild tigers have been seen in the forest around this area,___there used to be very few.
A when B where C what D which
选B,后面是非限制性定语从句,不能用that.先行词是表示地点的this area,用where.
2.Large quantities of materials are rare in this country,_____iron and steel are examples.
A OF which B in which C from which D for which
选A 先行词是materials ,所以用of which,与主句of materials 保持一致.
这道题很典型,一定要记住,考试常见.

b
首先这是非限制性定语从句，不能用that。先行词是this area，是个地点，前面没有介词，如果用which 应该要叫上in，成为in which，现在没有就用where。
a/d
example跟for搭配。ad符合题意。

1、B ，属于非限制性定语从句，地点状语从句
2、B ，在这里In which 还是引导地点状语从句，作用相当于是“where”

1. B
后面那个丛句是修饰this area，this area是一个地点，所以用where。
2. A/D
原因：for example搭配
