Peanut allergies (过敏) are among the most common and most dangerous of food allergies. A tiny exposure to peanuts can mean big trouble for a person with a peanut allergy—not just sneezing or coughing，but something as potentially deadly as narrowing of the airways.
But a recent study suggests that some children may be able to beat back their allergic reactions to peanuts by gradually introducing trace amounts of the nut into their diets. It's too early to say for certain，so if you have a peanut allergy，do not try this at home. But the first results look promising.
Two teams of scientists have been experimenting on a group“of 29 children who are allergic to peanuts”At the beginning of the study，each kid received less than 1/1，000 of a peanut per day. (Imagine splitting a peanut into 1，000 parts!) Over the course of the study， the children gradually increased the amount of the peanut in their diets
Nine of the children have been receiving the treatment for two years，and five of those nine now appear to be free of their peanut allergies，and can eat peanuts with no problem. But the other four have not benefited so much from the therapy（治疗）.
The two teams of scientists are now doing a follow-up study on two groups of children with the allergy. Children in one group will receive the new therapy，while the others will not. Researchers hope this study will help them learn if the therapy truly does work.
Scientists don't understand why some people get peanut allergies and others don't，but are trying to find a way to help people with the allergy. Because of the severity of some peanut allergies，scientists want to know the answer as soon as possible. “This is very encouraging， but remember，it's not something you try at home，”says one of the researchers.

own from the force of all the shaking and I started getting pretty scared(害怕). I don’t think my aunt moved the entire time. My mom had gotten under the table with me and was holding me to make sure I was OK I suppose. It seemed strange because no one really knew what to do. Peanuts to This
Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes． Confused, I glanced toward my stone-faced teacher． Having no choice, I slowly raised the report I had slaved over, hoping to hide myself． “What could be causing everyone to act this way?”
Quickly, I flashed back to the day Miss Lancelot gave me the task． This was the first real talk I received in my new school． It seemed simple: go on the Internet and find information about a man named George Washington． Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before． As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America． I stared at the screen, wondering which one my teacher meant． I called my grandfather for a golden piece of advice; flip （掷） a coin． Heads—the commander, and tails—the peanuts guy． Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver．
Weeks later, standing before this unfriendly mass, I was totally lost． Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong． As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution．” The whole world became quiet! How could I know that she meant that George Washington?
Obviously, my grade was awful． Heartbroken but fearless, I decided to turn this around． I talked to Miss Lancelot, but she insisted: No re-dos; no new grade． I felt that the punishment was not justified, and I believed I deserved a second chance． Consequently, I threw myself heartily into my work for the rest of the school year． Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation． I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade． Justice is sweet!

Two friends have an argument that breaks up their friendship forever, even though neither one can remember how the whole thing got started. Such sad events happen over and over in high schools across the country. In fact, according to an official report on youth violence, “In our country today, the greatest threat to the lives of children and adolescents is not disease or starvation or abandonment, but the terrible reality of violence”. Given that this is the case, why aren’t students taught to manage conflict the way they are taught to solve math problems, drive cars, or stay physically fit?
First of all, students need to realize that conflict is unavoidable. A report on violence among middle school and high school students indicates that most violent incidents between students begin with a relatively minor insult. For example, a fight could start over the fact that one student eats a peanut butter sandwich each lunchtime. Laughter over the sandwich can lead to insults, which in turn can lead to violence. The problem isn’t in the sandwich, but in the way students deal with the conflict.
Once students recognize that conflict is unavoidable, they can practice the golden rule of conflict resolution: stay calm. Once the student feels calmer, he or slid should choose words that will calm the other person down as well. Rude words, name-calling, and accusation only add fuel to the emotional fire. On the other hand, soft words spoken at a normal sound level can put out the fire before it explodes out of control.
After both sides have calmed down, they can use another key strategy for conflict resolution: listening. Listening allows the two sides to understand each other. One person should describe his or her side, and the other person should listen without interrupting. Afterward, the listener can ask non-threatening questions to clarify the speaker’s position. Then the two people should change roles.
Finally, students need to consider what they are hearing. This doesn’t mean trying to figure out what’s wrong with the other person. It means understanding what the real issue is and what both sides are trying to accomplish. For example, a shouting match over a peanut butter sandwich might happen because one person thinks the other person is unwilling to try new things. Students need to ask themselves questions such as these: How did this start? What do I really want? What am I afraid of? As the issue becomes clearer, the conflict often simply becomes smaller. Even if it doesn’t, careful thought helps both sides figure out a mutual solution.
There will always be conflict in schools, but that doesn’t mean there needs to be violence. After students in Atlanta started a conflict resolution program, according to Educators for Social Responsibility, “64% of the teachers reported less physical violence in the classroom; 75% of the teachers reported an increase in student cooperation; and 92% of the students felt better about themselves”. Learning to resolve conflicts can help students deal with friends, teachers, parents, bosses, and coworkers. In that way, conflict resolution is a basic life skill that should be taught in schools across the country.
