so与so that的用法区别?He walked slowly _____we could catch up with him.A.so B.so that

so引导结果状语，so that引导目的状语

b
肯定是B

so 强调客观结果
He walked slowly so it was pretty dark when he got home. (他并不想弄到天黑回家。只不过他走得慢，结果天就黑了。)
so that 强调主观意图。比如你的例句，他是故意走得慢，好让别人跟上。

so that 因此，用在句中。
so 用在句首，原因状语的引导词，

so that

A

既然都在说，那我说下我的看法：
答案：B
原因：so 不用在句中做连词，需要用标点隔开或直接拉到句首。so that 则只能在句中使用，其实上面的句子换个方法看更好理解为什么选B;
He walked so slowly that we could catch up with him.

这题选B
so就相当于中文的“所以”.如”他长的很帅,所以很多人喜欢他“."He is handsome so many people love him." 而so that 是表示以便,为了的意思,如“他用功读书,为了让他爸爸高兴”,"He studies very hard so that his father will be happy."
另要区分so that 和so.that.
so.that是表示如此．．．以致的意思． so that是连在一起用的,表示结果．如：我读更多的书,以便我能赶上我的同学．“I read more books so that I can catch up with my classmates.”so .that 是分开的,表示在什么条件下有的结果,that后加句子．如：“我太累了,以致我一吃完晚饭就去睡觉了．I was so tired that I went to bed as soon as I ate the supper.”
看“He is handsome so many people love him.”和” He is so handsome that many people love him.”
对了,so that=in order to do sth.

两个词都可以引导从句.
但是意义不同.
so指因此,所以.
而so that是为了如此, 以便于的意思.
所以应该选B.
