Question

求助~三个英语问题

先在这里谢谢咯~

1. I need to study because there is a test tomorrow.
表示明天有个测试不应该是用将来时吗，为什么不是there will be a test呢？

2. Many parents want their children to be lawyers and doctors after they graduate from college.
在他们毕业后为什么是after they graduate而不是after they graduated呢？

3. The students were very happy because the teacher said there was no homework.
Students must pass these exams before they can be admitted to college.
对比下这两个句子，主语同样都是学生，为什么第一个句子students前面加了定冠词the，而第二句没有加呢？

Answer 1

1.表示确定要发生的事情用现在时，比如说The bus sets off at 5 o'clock就是说这是原定好的
2.主句是现在时啊，时间状语从句当然也用现在时了
3.第一句话指的是特定的某一个班的学生，当然加定冠词the。第二句话是泛指，所以不用the

Answer 2

从句一般表将来
这里的THEY=THEIR CHILDREN，graduated成过去式了 在这里应该用一般表将来
加THE 就是特指的学生 不加就是泛指
