Answer 1

1.A
说的是一种现象，用动词原形就好了。而且结尾有today, 肯定不用were，用are

2C
介定a period，in which，in this period在这段期间，in which=when

3A
这里介定的是cases, 在这些案件中，客户的投诉导致了一些法律上的改变。

4B
因为他们是be trained for the jobs

5D
介定the village

6.D
介定occasions, 可以用when 或者 in which

7。世界上很多城市已经没有空间再开发了，纽约就是一个例子。
A. for which
因为New York is an example for前面的情况

追问

请问介定是什么意思。。。。。就是第三题。

追答

之所以用介词，说明它们有明确所指的事，必须先弄清楚它们介定的对象是什么，才能用对介词。

比如第三题空格后面的consumer complaints have resulted in changes in the law.
说的就是前面提到的cases中发生的情况。
所以要介定cases，就用in which 或者 where, 因为是 in cases...
