Peanut allergies (過敏) 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(治療).
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.
68.According to the passage,the peanut allergy     .
A. can be deadly if only a small amount is used
B. causes a lot of trouble for many parents
C. allows people to eat only small amounts of peanuts
D. is considered the least common and dangerous food allergy
69.Scientists are trying to treat peanut allergies by     .
A. exposing children with the allergy to as many peanuts as possible
B. changing the eating habits of children with peanut allergies gradually
C. giving children Peanuts in slowly increasing amounts
D. exploring ways to resist the feelings caused by peanut allergies
70.The experiment shows that     
A. people with peanut allergies can't use small amounts of peanuts in their diets.
B. children are more easily cured than adults
C. all children can be cured of their peanut allergies if given more time of treatment
D. about 55-percent children with peanut allergies have been cured
71. Scientists are now doing a follow-up study in order to     .
A. explore why some people get the illness while others don’t
B. show whether peanut allergies can really be dangerous
C. check whether the therapy really works or not
D. explore whether the allergy can be cured without treatment

第三部分:閱讀理解(共20小題;每小題2分,滿分40分)
閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項。
A
When I was a child , I remember that my mother decided that we would take a trip to visit my Aunt Sandy who lived in Mammoth Lakes, California. I was about 7 at the time but my memory does not fail me because I can recall my personal details .
We were sitting in the kitchen getting ready to have peanut butter and suddenly without warning the room started shaking. I remember thinking that it was weird(怪異)that construction workers must have been moving the house or something, but that it was weird that they would do it when we were still in it. I had a vivid imagination too. So everything started shaking and my aunt had this horrible look on her face as she dropped the knife of peanut-butter onto the ground and held on to the counter. My mom told me to get under the table, which as I think back was odd because what was happening was from the ground so what good was getting under a table going to do. The kitchen window soon broke out on its 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.
So finally the shaking stopped. The power was out and it took minutes before anyone really even started to move and talk again. My mother decided that we would leave the next morning. I don’t remember if we were only planning to stay for one night or if we were just stopping by on our way to Fresno where my mom had friends.

A.was eager to see Aunt Sandy      B.was too young to do anything

B.the kitchen window broke out on its own
C.a terrible earthquake took place suddenly     
D.they were warned to leave the room at once
58.Aunt dropped the knife of peanut-butter onto the ground because_________.
A.she was very busy   B.she was too frightened
C.everything shook hard    D.she didn’t use it any more
59.From the last paragraph we can know that________.
A.everyone began to make the house clean and tidy

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 (擲) 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!
【小題1】What did the author’s classmates think about his report?

A.Controversial.B.Ridiculous.C.Boring.D.Puzzling.
【小題2】Why was the author confused about the task?
A.He was unfamiliar with American history.
B.He followed the advice and flipped a coin.
C.He forgot his teacher’s instruction.
D.He was new at the school.
【小題3】The underlined word “burning” in Para. 3 probably means _______.
A.annoyedB.ashamedC.readyD.eager
【小題4】In the end, the author turned things around _______.
A.by redoing his task
B.through his own efforts
C.with the help of his grandfather
D.under the guidance of his headmaster

科目:高中英語 來源:2013屆天津市南開中學高三第四次月考英語試卷(帶解析) 題型:閱讀理解

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.
【小題1】This article is mainly about              .

A.the lives of school childrenB.the cause of arguments in schools
C.how to analyze youth violenceD.how to deal with school conflicts
【小題2】From Paragraph 2 we can learn that              .
A.violence is more likely to occur at lunchtime
B.a small conflict can lead to violence
C.students tend to lose their temper easily
D.the eating habit of a student is often the cause of a fight
【小題3】Why do students need to ask themselves the questions stated in Paragraph 5?
A.To make clear what the real issue is.
B.To get ready to try new things.
C.To find out who is to blame.
D.To figure out how to stop the shouting match.
【小題4】After the conflict resolution program was started in Atlanta, it was found that           .
A.more teachers felt better about themselves in schools
B.there was less student cooperation in the classroom
C.there was a decrease in classroom violence
D.the teacher-student relationship greatly improved
【小題5】The writer’s purpose for writing this article is to              .
A.complain about problems in school education
B.teach students different strategies for school life
C.inform teachers of the latest studies on school violence
D.advocate teaching conflict management in schools
