英语高手来！WE ARE WHAT WE EAT
下面这两段英语资料中有什么语法现象句式或者短语啊 讲课的时候需要用到 这是高1年纪的一篇课文
Choosing what to eat is no longer as easy as it once was．Our eating habits have changed, as has our way of life，and the fuel we need for our bodies is also different．Traditional diets often have too much fat and too many calories for the 21st-century person．If we want to keep up with the high pace of modern life，we had better learn to make the fight choices about what and how we eat．
Stores offer all kinds of food and snacks and we have to make many choices．When we choose what to buy and eat, we had better think whether the food will give us the nutrients we need．Some nutrients help build our body and make it stronger. Protein, for example，is good for our muscles．Fish，meat and beans contain a lot of protein. Calcium, which is found in eggs，milk and other dairy products，is good for our bones and teeth．We should also eat carbohydrates，the main fuel for our body，which we can get from bread，rice and noodles．Other nutrients，such as fibre and minerals，help keep our body functioning well．Vitamins, which we can get from eating vegetables，fruit，fish and drinking milk，help our body fight disease．
