以上三个句子属同一类型.要想会做题,就得先要懂句子结构.在此基础上,对句子进行分析,做题就容易了.
这三个句子——我们把选择项的事先放下不管——中间用逗号隔开,且没有连接词,说明不是并列句（并列句是由and,so,or,but,yet以及“；”（分号）连接的句子,逗号不行）.这样,你就可以判定空格处应该是缺连接词的——当然不是并列句的连接词,因为并列句的连接词前不能有介词,所以说每一个题中的两个句子间也不是并列关系.考虑到句子前的名词（如cultures； German,French and Russia； people ）,可以判断是定语从句,是each of /most of/ all of +关系代词引导的非限制性定语从句.因为 cultures和German,French and Russia都指“事物”,所以选择which；因为people指人,所以选whom.（你给的后两个题的答案有问题）
如果上面三个句子中间是句号,而不是逗号,那每一组中的两个句子就都是独立的句子了,没有从属关系.这时,你必须选择them,用them来代替前面句子中的cultures； German,French and Russia； people.
Because of the financial crisis,days are gone ___local 5-star hotels charged 6,000 yuan for one night.
A if B when C which D since
这个题考的是与定语从句的后置.应该选when.正常语序是这样的：
Because of the financial crisis,days when local 5-star hotels charged 6,000 yuan for one night are gone.
你可以看出,定语从句when local 5-star hotels charged 6,000 yuan for one night 是修饰主语days的,谓语是are gone.这样的话,句子的主语加上他的定语（从句）就太长了,头重脚轻,不平衡,所以就把定语从句移到谓语are gone之后了.
-What do you think of teacher ,Bob?
-I find it fun and challenging.It is a job __ you are doing something serious but interesting.
A where B when C who D which
这句的答案是where,那是因为象job,point,situation,stage,case,business,area,position,joints,platform,appliances,screen等一些词,都是可以作为一个“点”来理解的.再给你几个例句：
Her illness has developed to the point where nobody can cure her.
Here is the telephone number where I will be.Call me if any trouble arises.
The knee is the joints where the thigh bone meets the large bone of the lower leg.
All these activities can serve as a platform where you might find the one you love.
Can you name a few more electrical appliances where electricity is used to produce heat?
至于 Later in this chapter cases will be introduced to readers ___ consumers complanints have resulted in changes in the law.这个句子,因为你没有发答案选项,有点问题.是不是有whose选项?
再问： Later in this chapter cases will be introduced to readers ___ consumers complanints have resulted in changes in the law.的选项A where B when C who D which
再答： Later in this chapter cases will be introduced to readers ___ consumers complanints have resulted in changes in the law.的选项A where B when C who D which 这个题你不妨这样去做，把四个答案都放到句子里，看意思能否通顺。我觉得这是最简单的办法。 cases will be introduced to readers 是主句，consumers complanints have resulted in changes in the law在句子中的句子，选型又是连接词，是从句。 Later in this chapter 是句中的状语了。问题是我们要选择一个什么连接词把主句和从句连接起来。由于主句和从句都是完整的句子，主谓宾都有，可以排除who，which；那剩下的就是两个作状语的when和where了。根据主句与从句之间的关系，你会知道该选哪一个的。（事先有标准答案吗？） 学习英语，学好英语，要学会分析句子。会了，再结合我们汉语来对照理解，进步就快了。
