enter后面到底能否接介词into

After a while, the stranger entered into conversation with me.

这句话为何要用 into 呢？

enter 后面到底能否接介词 into 有什么区别是：

1. 若表示进入某一具体场合、建筑物等，是及物动词，其后一般不接介词 into。如：

我一进屋大伙就安静了下来。

误：Silence fell as I entered into the room.

正：Silence fell as I entered the room.

2. 如果是表示开始进入或从事某一状况或活动，或用于较抽象的定义，则可后接 into。如：

Let’s enter into the subject of taxes. 大家来讨论一下税款问题。

He entered into partnership with his brother. 他和弟弟合伙做业务。

The nations entered into a new agreement. 这类国家签署了一项新的协议。

I can enter into your feelings at the loss of your son. 我理解你失去儿子后的心情。

This possibility never entered into our calculations. 大家从未考虑过有这种可能性。
