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

答案

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.
