麻烦指出这段话中的错误,China’s room is changingLi Ping’s parent made a

1.China's 错,改为：Chinese
2.is changing改为：is being changed
3.parent我不知道你是指父母亲还是指单亲,但是这句话,如果指单亲就没错,如果你想指父母,就改为:parents.
4.effort改为：efforts
5.Mr.coggins错,改为：Mr.Coggins
6.think 改为thought
5.room's decoration改为：the decoration of the room
6.is 改为：was
7.decide改为decided
go back 改为：going back
这是我的意见,请参考.如果觉得可以就采纳我的答案吧,我可是认真回答的

单就语法来讲,第三段：
Mr.coggins, Li Ping’s English teacher THINKS/THOUGHT room’s decoration is/WAS nice in China and DECIDED/DECIDES to decorate her own room after GOING back.
解释：
谓语动词用第三人称单数形式，

China’s room is being changed
Li Ping’s parent made a lot of efforts to decorate each room to make the whole apartment nice and comfortable.
Mr.coggins, Li Ping’s English teacher thinks room’s decoration is nice in China and decides to decorate her own room after going back
