我需要这几道题每一道题目的分析.
定语从句真的搞不懂.不管怎么分析,语法也好,通俗的说也好.反正我要是能懂能掌握就好了.泪奔.感激不尽.

【1】（1）中 facts 作主语,所以that which 都可以用.（2）句是同位语从句,所以facts就是指the earth and all the other planets move around the sun.所以用that引导.
【2】（1）中 films 作主语,且有最高级修饰、为复数,所以用that were（2）句,类似地 films 作主语且有最高级修饰,但有the only (very) one of 修饰,所以是指一个.用单数
【3】两句都为非限制性定语从句,所以B D 排除,（1）句Washington做从句的主语,所以用which来替代（2）句中从句成分完整,所以用where来代替Washington作状语,
【4】（1）flat作主语,有the only修饰,只能用that. （2）live是不及物动词,短语为live in ,而从句中并没有 in 所以用where 引导作状语,也可以用 in which.
【5】你括号中的是不是答案啊,我觉得这题应该要用which啊,the persons 在从句中作表语所以只能用which.况且能用 whom 的就能有 who 啊.不好意思啊
【6】（1）有介词只能用whom,这应该是唯一区别吧.（2）很明显three sisters在从句中作主语,所以只能用whom.
【7】与前一题类似地,有介词只能用which.
【8】首先,workplace有the second ,即序数词修饰,只能用that.排除B C.第二空,意思是这个工作场所的工人们.,所以用which代替 workplace,whom显然没道理,谁的?前文没有交代,当然不可以代替啦.
好累哦,一个一个打,不过如果对你有帮助的话那也就值了.希望是这样.还没有明白的话在不补充问一下吧,谢谢.
