任务型阅读 Do you love food? Whether you're a foodie or someone who just likes eating, there is so much to choose from. We know that too much of the wrong kind of food can be bad for our health, but for some people having a food allergy means that eating certain things can actually be harmful. Such cases may seem uncommon. An allergy is caused by the immune (免疫的) system fighting substances in the environment.  It means that people have to follow strict dietary restrictions, otherwise their lives may be put at risk. Allergy specialist Dr. Adam Fox says "if you look back over, say, 30 or 40 years… there are much more serious allergic problems around now than there were." Last year a teenager died after suffering an allergic reaction from eating a piece of bread containing peanuts. This led to a call for better food-labeling laws. Research has found that this problem is particularly affecting children.  Dr. Alexandra Santos from King's College London says "food allergy now affects about 7% of children in the UK and 9% of those in Australia, for example. Across Europe, 2% of adults have food allergies." So what might be the cause? Dr. Santos says, the increase in allergies is not simply the effect of society becoming more aware of them and better at diagnosing them. She adds that possible factors are pollution, dietary changes and less exposure to bacteria, which change how our immune systems respond. She points out that it's very common for migrants who move to another country to develop food allergies in their new location. A. It seems to be more environmental. B. A food allergy can affect you at any age. C. Food allergies can cause life-threatening reactions. D. Yet in fact, food allergies are affecting more and more of us. E.

We often hear about people having allergies to dairy products or to nuts. 答案：【1】D【2】C【3】G【4】E【5】A
