英语翻译
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．
But the choices we make are not just about nutrition．Many people today make choices about their eating habits based on what they believe．Eating habits become part of who we are．Some people become vegetarians because they believe it is healthier not to eat meat or because they think we should not kill animals for food.Others become vegans and will not eat any animal products at all,not even yoghurt or eggs．We also make choices based on how the products ale grown or made：environmentally friendly food,or “eco—food”,is produced by companies who have tried to use green and clean ways to grow it．Organic vegetables are those that are grown without chemicals that can be harmful to human beings or the environment．
Because we have so much to choose from,many companies and stores offer advice about what we should eat．Books,magazines and television shows tell us about food and pills we should buy to become smarter,healthier and more beautiful．It is probably better,however,if we spend our time and money on buying good food and keeping a balanced diet．If we eat healthy food in the right amounts,we do not have to buy any supplements．The same goes for“crash diets”that some companies say will make us lose weight fast．Instead of eating expensive diet foods or going on unhealthy diets,we can simply try to eat less fat and sugar and exercise more.
The best way to make sure that we will feel and look fine is to develop healthy eating habits．We ought to learn more about our body and the fuel it needs to keep fit．Only in that way will we be ready for the challenges and opportunities in life．

这么长才十分你也太抠了吧,做摆渡人最大的悲哀就是人挂了分没送完.
选择我们的食物已经不再象以前那么容易了.我们的饮食习惯已经改变,就象我们的生活习惯一样.我们身体所要加的“汽油”（形容营养）是不同的.对于生活在21世纪的人,传统的饮食搭配含有太多的脂肪和热量.如果我们想跟上现代生活的步伐,我们就不得不在吃什么和怎么吃这两方面做出艰难的选择.
商店为我们提供各种各样的食物和快餐所以我们必须作出选择.在我们选择买什么东西来吃的时候,我们最好考虑一下,这个食物是否提供我们所需的营养.有些营养对使我们身体成长和变得更强壮有帮助.例如蛋白质,它对我们的肌肉有好处,鱼、肉和豆类食品都富含蛋白质.在鸡蛋、牛奶和其他一些食品中含有钙,钙对我们的骨头和牙齿有好处.我们也应该吃含有碳水化合物的食物,它是我们身体运作的能量.我们还能够在蔬菜、水果、鱼和牛奶中摄取维生素,它能帮助我们抵御疾病.
但在选择食物时我们不仅仅只需要考虑到营养的问题.现在许多人的饮食习惯是建立在他们的信仰上的.饮食习惯成为了人类象征的一部分.部分人成为了素食主义者,因为他们相信不吃肉食会更健康或者他们认为我们不应该为了食物而杀死动物.还有一些人成为了严格的素食主义者而不会食用任何肉类制品,他们甚至不喝酸奶也不吃鸡蛋.我们选择食物时也会考虑到这些食物是怎么种出来的或者是怎么制作而成的.绿色食品和生态食品,是由一些致力于用环保的、卫生的生产方式生产出来的.有机蔬菜是那种种植过程中没有施加任何对人体和环境有害的化学药品的蔬菜.
由于我们拥有许许多多的选择,许多公司和商店都为我们提供饮食建议.书、杂志和电视节目都告诉我们,我们应该吃什么食物和药物使自己更时尚、更健康和更漂亮.这可能是好的,然而,如果我们把钱花在购买好的食物并保持均衡的饮食,如果我们食用好的食品,我们就不需要买其他的任何东西补充营养.同样的道理,某些公司推出的所谓能够使我们快速减肥的“健康食品”对我们来说是没有必要的,我们只需要吃脂肪和糖份低的食品,多做运动,就能达到同样的目标.
使我们看起来健康美丽的最简单方法就是建立起良好的饮食习惯.我们应该对自己的身体有更深刻的理解和了解能保持健康的营养的获取方法.那是我们能够从容应对生活中的机遇和挑战的唯一途径.
