（已纠正）1 I don't know （very）（much）（about）（using）commas
2 I can swim very well.
3 I'll show them to you as soon as they will come out
这句话里,will要去掉.
因为they come out虽然是一个还未发生的情况,但as soon as后面要加一般现在时的从句,因为这个短语本身的意思就是"一...就...".
举个例子,就像汉语中的,"他一回家我就打电话给你".
这个"回家"虽然没有发生,但是还是要用一般时"回家",而不是将来时"将回家".
所以这句话正确的应该是
I'll show them to you as soon as they come out.
