楼上有点小错误,我纠正一下;
第一:习惯应该是:habits
第二:词组搭配问题:
be bad for ……
be harmful to……
所以有两种表达方式:
1.these habits are harmful to health
2.these habits are bad for health
These habits are harmful to your health.These habits make against your health.These habits are detrimental to your health. 我个人觉得对...有害用be detrimental to 好点,其它的太常见了。
All these habbits are bad / harmful for you health.
