放在动作词后面
紧跟在 like, want, buy 这类动作词后面时，用搭档词。它指的是动作落在谁身上。
I want it.
We like them.
You need her.
Not "I like they." — say "I like them.". 在动作词后面，动作落在谁身上，谁就用搭档词：they → them。
试一试: Diego has new shoes. You say: I love ___. (them / they / their) 答案: them — 如果你选了 "they"，那是做事的一方用的词。这里鞋子在动作词 love 后面，所以要用搭档词：I love them.
放在 for, with, to 后面
在 for, with, to, at 后面，用搭档词：for him，with her，to them，at me。
This is for you.
The bag is for him.
Ethan is with us.
Not "This is for he." — say "This is for him.". 在 for 后面要换：he → him。
