帮我看一下这篇英语作文哪里错了

Nowadays, people have a lot of pressure.Where stress come from? What should they do to solve these problems?
Parents always want their children to be number one.Therefore they offer their children various class.However, many children hate most of the class.What's more, the children lost their freedom.In my opinion, parents should give their children more freedom and let them study independently.
Adults also has pressure.They should compete with their colleagues.It is hard to get appreciation from their boss.They must try their best to get along well with their customers. I think they should have more time to relax.And they can also talk to their friends, companion or the elder to solve the problem.
The elder has retired.It is time to enjoy themselves.However they also have pressure.They have no income.When they get older, they will have a lot of health problems.And they often feel lonely.So I suggest the young care for their parents more and spend more time with them.

第一段 Where stress come from? 应该是 Where does the stress come from?

第二段 class 改为 classes

第三段Adults also has pressure. has 改为have， boss 改为bosses

这是从语法方面来说的。

内容上：
第二段主要描述的是孩子们的压力，要具体说父母望子成龙望女成凤，所以给孩子报了很多特长班之类的课程，父母的期望给了孩子很大的压力，让孩子失去了自由，父母要理解孩子，不要给孩子报那么多课程，尽量选择孩子感兴趣的课程，这样才能两全其美。

最后最好总结一下，要不然太突兀的就结束了。

i saw he cooking very fast. 应该改为： i saw him cooking very fast. 或 i saw that he cooked very fast. --- i thought my father forgot adding salt. 挑一点的话子句应该用过去完成时，没学过就算了： i thought my father had forgotten adding salt. --- he is too careless. 应该是过去时： he was too careless. --- i never ever eat he cooked food. 应改为： i would never ever eat the food cooked by him again. --- 书面语最好不要用缩写： wasn't -> was not couldn't -> could not --- 作文写得不错。
