几句英语病句求修改
外教从我的作文里找出有很多语法错误的句子,但我不知道该怎么改.括号内的是错的地方.求教.
1.The
real happiness (is) not depend on how much money we (own) or how powerful we are,
it just (depend) on whether we have a positive mind.
2.(Be
a richest man is meaningless)
3.(It just because when he was struggling for his aim,he had a positive mind,so
he got happiness.)
4.(Compare
with himself nowadays,)
5.I
(always didn’t) turn to my teacher for help when I met mathematical difficulties
6.I
think independent mean(to confidence and adamancy).

does; have; depends
Being the
it is just because he was struggling for his aim and had a positive mind that he got happiness.
Compared 
usedn't to
having confidence and adamancy
仅供参考请问第5句和第6句我为什么错?5. 表过去的习惯时,往往借助于短语used to do sth.
6. mean 译为“意味着” 时, 其用法是: mean doing sth.

对英语的表述应追求语言使用地道,真实,符合英美国家的表达习惯。
你会进步的!
