e.g. People are becoming more and more health-conscious. They begin to pay a lot of attention to what they eat.
e.g. I was a little overweight three years ago, so I made up my mind to shed pounds(减肥). That‘s why I started jogging every day.
e.g. I used to be very sedentary in high school. I never worked out(健身) and because of that, I put on so much weight(增重).
e.g. I lead a very active lifestyle, which is something I‘m really proud of. For example, I go swimming on a pretty regular basis and I also like to play basketball.
e.g. I was a huge fan of chocolate when I was a child, but now, I hardly ever eat anything that‘s fattening.
答：your和 yourself 虽然都是代词
yourself是反身代词，后面不跟其它词，所以yourself healthy是错误的，不过可以说：keep yourself healthy，这里用healthy这个形容词与keep有关，与yourself无关
答：那就用healthy和health当例子吧＜br/＞＜br/＞例：You should exercise more to keep healthy＜br/＞I’m pretty healthy.＜br/＞＜br/＞例句healthy前面都有修饰词。＜br/＞＜br/＞Look after your health,please!＜br/＞＜br/＞还有楼上说的：名词如一般作主语，而形容词一般作表语或定语。 ＜br/＞＜br/＞Our health is very important.(名词作主语) ＜br/＞Eating vegetables is healthy.（形容词作表语） ＜br/＞He is a healthy man.(形容词作定语)＜br/＞＜br/＞特殊的：(be) in good healthy 身体状况好的 The old is in good health.
答：be in good health身体好
be good health健康
答：是human health,human‘s health是错误的.
