Question

jack wanted to start his business but his parents don't approve of him leaving school this year 对

jack wanted to start his business but his parents didn't approve of him leaving school this year 对么？ 我主要想问啊能用approve

Answer 1

你好，我是英语师范学校毕业的，希望可以帮助到你！
这句话里应该将don't 改为didn't，因为前面已经用wanted表示过去式了。还有，要将him改为he.
另外，你需要注意approve 与approve of 的区别。
approve是动词，作及物动词时用作approve sth.
做不及物动词时，approve sb. sth.
approve of +doing sth. /approve of sth.
如果你要用approve 代替approve of ，则原句应该改为：
Jack wanted to start his business,but his parents didn't approve him leaving school this year.

Answer 2

补充的那个是对的，因为前面是过去式，所以后面要保持时态的一致性

Answer 3

don't 应该改为did not
