keep in 后面能加名词吗？知道具体用法最好解释一下。O(∩_∩)O谢谢啦

1，加名词，动名词；
Let's keep in touch.让我们保持联系。

He could scarcely keep in his indignation.
他愤怒得难以自持。
2，加介词短语；
Have you noticed how he tries to keep in with the boss?
你注意到他多巴结老板了吗?
3，加从句； ,
It's best to keep in while the temperature is too low.
气温太低时最好呆在屋里。
4，Please keep the secret in.
请保守秘密。
其实是这样的，keep in 相当于及物动词，那就是说，即使只是说“It's best to keep in"
也是通顺的，后面只不过是加了一些补语或者状语修饰而已。
