A:Hi,Kevin.Your roommate told me that I could find you in the TV lounge.What are you doing here? B:What does it look like I am doing? A:Well,it looks like you are watching television.But we have a linear algebra midterm tomorrow,so I thought you would be studing for it and I can study with you.(这里前面都是thought,怎么这里就是一般现在时了呢？应该是说话人A先前想的可以和B一起学习啊？如果是正确的这属于一般现在时的什么用法？) B:Oh,well,I was just taking a break.This linear algebra stuff gives me a headache if I work on it too long.(这里应该是先前我看linear algebra 头疼吧？如果是正确的这属于一般现在时的什么用法？)
