be similar in...在某一点上相似！
in 的后面是which引导的宾语从句！
意思：这俩个城市都有很高的降雨量，这一点上俩者颇为相似。

C
the two areas are similar_____they both have a high rainfall 从题中可以知道两个地方的相同点是 they have ....而except that和besides that两个引导的从句前者指不包括从句内容,后者指包括从句内容,和整句放在一起都说不通,所以排除A,D
that引导从句时不能放在介词的后面,所以排除B

in which = where
前者与后者为并列关系
Beijing is a beautiful city in which I was born.
或者这样说：
Beijing is a beautiful city where I was born.
我也是跟别人新学的!

c

选B
in that是因为的意思.
你的答案是错的.

根据意思
后面有both说明是相似的地方
A，D都说除了，感觉后面不相似，因此不对
定语从句的话that前面不能加介词的
后者in which=where
恩

再定语中,只有which可以用介词来修饰,that
不行
