thewomanilove

这句话可以用四种方法表示：

1. 用whom是严格的书面语：The woman whom I love is moving to the south.

2. 用who是随便的书面语或口语：The woman who I love is moving to the south.

3. 省去关系词是更通俗的口语：The woman I love is moving to the south.

4. 用that是淡化先行词表示具体人的概念：The woman that I love is moving to the south.（意思有所改变：我爱的那类女人正迁往北方。注意：这里不再是“那个女人”了。）
