Question

帮我看下这几句英文写得对不对

we realize that MSN is the most important tool of Macao teenagers,and they use it almost everyday

Answer 1

不是很对tool是让macao teenagers使用的 后面的and有点多余，我觉得应该改成：
we realize that MSN is the most important tool that Macao teenagers use, they use it almost everyday

Answer 2

we think that MSN is the most important tool for these Macao teenagers,because they use it almost every day.(every/each day分开写才对)
