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, eating certain things can actually be harmful. Now it is seemingly 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. 1.It means people have to spend their lives following strict dietary restrictions and worrying about the ingredients of everything they consume. We often hear about people having allergies to dairy products and to peanuts. Last year a teenager died after suffering a fatal allergic reaction from eating a baguette containing sesame seeds. 2.

Research has found that this problem is particularly affecting children. 3. Dr Alexandra Santos from King’s College London says food allergy now affects about 7 percent of children in the UK, and 9 percent of those in Australia.

4. Dr Santos says, the increase in allergies is not simply the effect of society becoming more aware of them and better at diagnosing them. 5. She adds that possible factors are pollution, dietary changes and less exposure to bacteria, which change how our immune systems respond.

A.So what might be the cause?

B.It seems to be more environmental.

C.Similarly, food allergic reaction is deadly.

D.This led to a call for better food-labeling laws.

E.Besides, more adults are suffering from food allergies.

F.However, food allergies can cause life-threatening reactions.

G.More and more of them are having allergic reactions to certain foodstuffs.

When we’re in need, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions (延伸) of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?

In the past the generation gap included a technology gap, where children were up to date with latest technology and parents were left behind, content to continue their day to day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to educate themselves about social networking sites.

These days many people are attracted to social networking sites because they can choose who they have around them; there’s also a certain amount of control over privacy that we don’t get in real life. Sometimes we feel that privacy is violated (侵犯）when we must accept a “friend” request from a parent or family member.

It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.

A recent survey suggested that parents shouldn’t take it personally if their child ignores their request: “When a teen ignores a parent’s friend request, it doesn’t necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to be independent.”

Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friends list.
