1 . 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 eating certain things can actually be harmful — and now, it seems, this is affecting more and more of us.

An allergy is caused by the immune system fighting substances in the environment, known as allergens, that it should see as harmless. Food allergies can cause life-threatening reactions, which means people have to spend their lives following strict dietary restrictions and worrying about the ingredients of everything they consume. Allergy specialist Dr. Adam Fox says “if you look back over, say, 30 or 40 years...there are much more allergic problems around now than there were. ”

We often hear about people having allergies to dairy products and to peanuts. Last year a 15-year-old girl died after suffering a fatal allergic reaction from eating a baguette containing sesame seeds. This led to a call for better food-labeling laws.

Research has found that this problem is particularly affecting children. More and more of them are having allergic reactions to certain foodstuffs. Writing for the BBC website, 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; it seems to be more environmental. She says possible factors are “pollution, dietary changes and less exposure to microbes, which change how our immune systems respond.” She points out that it’s very common for migrants who move to another country to develop asthma (哮喘) and food allergies in their new location.

A lot of work is being done to try and find a cure, but that’s not easy. So for now allergy sufferers. must watch what they eat and they must rely on clear and accurate labeling.

2 . At noon, I would race breathlessly home, a ten-minute walk from my school. My mother was waiting for me with pleasure to have lunch while I shared what happened at school.

I had been picked to be the princess in the school play, and for weeks my mother had rehearsed (排练) my lines so hard with me. But no matter how easily I acted at home, hardly had I stepped on stage when every word escaped me. Finally, my teacher asked me to change to a narrator’s (解说员) part. Her word. kindly expressed, still hurt, especially when I saw my part go to another girl.

I didn’t tell my mother what had happened that day. But she sensed my pain. Instead of suggesting we practice my lines, she asked if I wanted to walk in the yard.

Under the rose vine, we could see yellow dandelions (蒲公英), as if a painter had touched our landscape with shades of gold. I watched my mother casually bend down by one dandelion. “I’m going to dig up all these weeds, she said, pulling it up by its roots.” From now on, we’ll have only roses in this garden. ”

“But I like dandelions,” I argued. “All flowers are beautiful-even dandelions.”

My mother asked thoughtfully, “Yes, every flower gives pleasure in its own way, doesn’t it?” I nodded, pleased I had won her over. “And that is true of people too,” she added. I burst into tears, a mixture of relief and regret swelling up as I told her what had happened.

“But you will be a beautiful narrator,” she said, encouraging me as she did. “The narrator’s part is important, too.” Composing myself gradually, I began to accept the narrator’s part. Then came the performance day. I was still nervous, but it was at that very moment that I found a dandelion in my pocket. It was obvious that my mom secretly put the flower there, which magically gave me confidence.

Today we experienced enjoyable period of English class as usually. As soon as the bell rang, our teacher began to divide us from several groups to do the writing.
