1. 30% of the people without doing sports. 30% of the people go to bed and get up late.In addition.20% of people has another bad habit. 这应该是三句话吧,描述三种情况.既然是三句话,那么30% of the people without doing sports是没有谓语动词,你可以写成30% of the people don't sport. sport这个词本身就是运动的意思,没必要加do,或者你可以用do exercise表示做运动. 再看第二句30% of the people go to bed and get up late这个主语是复数,动词你用go 第三句20% of people has another bad habit,这个时候谓语你用has,同样的主语你上个看成复数,这个看成单数.你要把has改成have,因为20% of people 不可能只表示一个人. 2.For example 前面的句号改成逗号,可能是你随意填上去的,因为smoking and drinking wine 这不是一局完整的话,你只是照着前面的坏习惯举例说明. 3.I think all of these are bed of healthy 对……有害,应该是be bad for 不擅长做……be bad at doing sth 4.最后一个单词habit要用复数,你描述的坏习惯不止一种.
