关于用that不用which的句子!
1．当关系代词在定语从句中用做表语时,通常用that．
这句话给的例子是 China is not the country (that) it was .
2．当要避免重复时．
Which is the course that we are to take

答案

1．
China is not the country (that) it was .
（中国已是今非昔比.）
这里,that it was 确是the country的定语（即：什么样的country呢?it was the country --“曾经”的country,that代country,作it was的表语.）
2.
Which is the course that we are to take
（那就是我们要采取的方针吗?）
在that处用which也是可以的,但从修辞的角度讲,英美人很忌讳这样的重复,那给人用词不丰,江郎才尽的感觉,所以在一句话一个段落中常常采用多样词汇、多种表达形式.
