look for them還是look them for

是look for them，例如：

1、But we didn't look for them.因為我們從未找尋過它們。

2、I can not find my family members. I don't even know how to look for them.我找不到家人了，我也不知道去哪裏找。

3、So very seldom do we really pay attention to the fact that life does have rules if you look for them.我們很少真正去注意這個事實那就是如果你仔細去找生活中是存在規則的。
