study in --studied in

all those things change改成all those things have changed更好

in a old school--in an old school

Nowadays,people have lived in ---Nowadays,people are living in感觉更顺吧

基本上词语使用没什么问题，但是如果表达更多样化会更好哦

those改为these change改为have changed

people have lived in a tall
have lived 改为live

Children can also get a good education in a modern school.
