in to和into的区别是什么？

① into是介词； 而in to是副词in＋介词 to； 因此into是表示动作或运动的方向， 朝向是某个地方的内部； 而in to理论上没有关联， 只是根据in前面的动词或to后面的名词来判断使用或出现的条件。 比如： He turned his paper in to his teacher. 这里的in与其说是和to一起用， 不如说是turn ... in的延续。
② 判断使用的一个关键： 设想into回答的是where（目的）的问句； 而in to则是否能替代为in order to。 比如：
I am afraid to go into that place. ---> Where? into that place. 不能是in to；
He came in to get his money. ---> He came in, in order to get his money. 不是into.
③ into还有“变成”，“接触”甚至“感兴趣”的意思； 对应的可替换的词是“result of change”和“against”以及“interested”
He changed into a monster. -- result of change
He drove into a tree. -- against
He is really into this book. -- interested

补充一下
in和into的区别
in，into都有“...里”的含义，作为一组易混淆的词，in和into的区别有以下几点：

1.in意为“在…内”，是表示静态的介词。如：
“Where's Susie?" "In the bedroom." ”苏西在哪里？” “在卧室。”
She walked into the room.她走进了房间。

2.into意为“进…里”，是表示动态的复合介词。如：
She came into my room holding a paper.她拿份报纸走进房间。
I walked out into the garden to think.我走出来到花园里去想问题。

3.在 throw,jump,cut,push, break, lay, fall等动词之后，既可以用in，也可以用into。这时into一般侧重于移动，in则侧重于移动的终止。
She threw her ring into the air.她把戒指扔向空中。
She threw her ring in(to)the river.她把戒指扔到河里了。

sit down，put后面一般用in
He sat down in his favourite armchair.(NOT He sat down into...)他坐在他最喜欢的扶手椅里。
I put my hand in my pocket.我把手放在口袋里。
