enter 和enter into

题目

enter 和enter into
有什么区别呢?有到选择题he was still smiling when the door opened and his wife____.
填enter 还是enter into呢?为什么阿?

答案

enter可作及物和不及物动词,即进入的意思.
enter into 是进入什么状态,着手做某事的意思
如 Let's not enter into details at this stage.
咱们不要在现阶段著手处理具体问题.
The country entered into a state of war.
这个国家进入战争状态.
两者意思完全不同哈,不可互换
