第一部分阅读理解(共两节，满分40分)

第一节(共15小题；每小题2分，满分30分)

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

A

The food we eat seems to have a great effect on our health.Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat.Some research has shown that perhaps 80% of human illness is related to food and 40% of cancer is related to food as well.That food is related to illness is not a new discovery.In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives(添加剂)caused cancer.

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings(包装)of foods are helpful or harmful.The additives which we eat are not all so direct.Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows.Sometimes similar things are supplied to animals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price o n the market.Although some countries have tried to control such things, the practice continues.

【语篇解读】本文告诉我们要特别注意自己所吃的食物。因为食物可以让我们生存，也可以让我们患病。

If you really want to go green, here's good news: eating green is good for you.The very foods with a high carbon cost—meat, pork, dairy products, processed snacks —also tend to be filled with fat and calories.A green diet would be mostly vegetables and fruits, whole grains, fish and lean meat like chicken—a diet that's eco－ and waistline－friendly.Eating green can be healthier and beneficial to the climate.

It may be hard to believe that a meal at McDonald's produces more carbon than your trip to a far－away place.More than 37% of the world's land is used for agriculture, much of which was once forested.Deforestation (砍伐森林) is a major source of carbon.The fertilizer (化肥) and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate.
