Question

一开学就遇到了以前没学好的英语问题，希望大家帮帮我，拜托了(*^__^*) O(∩_∩)O ↖(^ω^)↗
第一个病句是将来时态O(∩_∩)O哈！

Answer 1

1.there are not going be schools in 100 years没有there have 句型，要么是there be ，要么是have，两者都可表示有，但不能混用
2.they will be able to pass the exam，该句译为：别担心，他们会通过考试的，此处表示将来时的意味

Answer 2

There won't have schools in 100 years later.

加上ago

They are able to pass the exam.

be改为are

Answer 3

第一句改成：It won't have schools in 100 years there.
第二句改成：Don't worry ,they will be able to pass the exam.
