翻译成英语：因为健康很重要,我们每天不能做充足的锻炼,我们总是感到很累,因此我们需要做更多的锻炼

我觉得汉语应该加一点东西。改成：因为健康很重要，“但是”我们每天不能做充足的锻炼，我们总是感到很累，因此我们需要做更多的锻炼。翻译见下一个回答

because health is so important that we have not to do enough exercise ,if so we are always feeling tired everyday .Therefore do more exercise we need..

Because health is very important, we can't do enough exercise, we always feel very tired, so we need to do more exercise.

Health is very important，we can't do plenty of exercise every day and always feel very tired.So we need to do more exercise. 楼上的语句错误了啊！！
