同学晚上好。
很高兴为你解答。
1 such as teaching buildings，library，dormitory，canteen and classroom.
such as后面的名词是并列的，因此要么都是复数，要么都是单数，要保持一致。
所以把教学楼改为单数。
2 The next
接下来直接用next就好了，不需加the。
3 I learned how to say something in classroom to use”there is”and “there are”
有两种改法：① 把to use改为using ；②I learned how to use”there is”and “there are”to say something in classroom  让 to say做to use的目的状语，“我学会了怎么用there is 和 there are 说教室里的东西。”
4 I learned how to tell others locations, Use“in”,“at”,“next to”,“behind”,“in the front of”and“under”and so on,to describe locations,
中间use的形式不对，，可以用by using 改为状语，结构上更加紧凑一些，“通过使用”。
5 the clock is on the wall above the blackboard
调整顺序 “墙上的钟表在黑板上”，on the wall是修饰clock的，因此改为 the clock on the wall is above the blackboard。
6 I learned how to describe which are the things in
改为I learned how to describe things which are in。


祝天天向上！
