如果這世上沒有了學校,是好是壞?

Of course 壞!!
If this world don't have school,

Bad:1.we can't learn any useful thing.
2.we can't find a job after study.
3.we will feel boring and meaningless.
4.if teachers not going to teach us,then our parents may teach us themselves or let some profeshional person teach us.

Good:1.we can try to與人相處.

没有了学校，一定不好咯。因为学校是培养国家栋梁的地方，虽然我并不是什么栋梁，但是自问在学校里我学了很多野，而且更享受返学的乐趣添。

當然是壞啦。
