llyliuliyum

2,D 里的 that 做什么成分？连接副词？代词？

2。明白了，since本身就是conj. 不用加that

可是感觉意思上since比because要好

uniqueness

since=as=because/ conj

当因为讲的时候，没有本质区别，纯属个人习惯

Because it was getting late, we walked faster.

Since I have no money, I can't buy any food.

As I was late, I hurried along.

当然since 还有从。。以来，在。。。以后的意思

as的意思就多拉
