The newly built cafe,the walls of ______ are painted light g

选D.考察定语从句.
介词of+关系代词which.
1. The newly built cafe is really a peaceful place. 新建的咖啡屋真是个平静的地方.
这已经是完整的句子机构了,中间的部分肯定就不能再是句子.先行词是cafe,关系代词which指代cafe. 这里的the walls of which=whose walls.
也就是The walls of cafe are painted light green. 咖啡屋的墙壁被涂上淡绿色.
这里只不过用which代cafe.

2.that在定语从句中,that前不能用介词of的,排除A.

3. it是代词,指代cafe,一样不行.因为这样的话,有两个谓语动词 are painted和后面的 is .

4. what无法引导定语从句.

不懂再追问》》》
望采纳,祝学习进步!

答案选D.which
which引导的是个定语从句。
因为主语是cafe，引导定语从句时，不用能whose，只能用of which表示所有格。
那家新建的咖啡馆，墙涂成浅绿色的那家，真是个安静的地方。

这道题只能选 D ,为非限制性定语从句，the +n + of +which/whom+从句修饰和限制cafe的。 这之前必须是“，”而不是“。”否则就真的该选AB了。主句就是The newly built cafe is really a peaceful place.
