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.
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

Here are some of the most common causes of fatigue, and what you can do about them.
Inadequate Sleep. If you don’t get enough sleep you’ll be tired but it’s rare that busy people get enough sleep. When there aren’t enough hours in the day to do everything, something has to give, and that’s usually sleep. Don’t fool yourself that you can get by on five or six hours of sleep a night. Most people need at least eight hours and some even more.
Hormone Imbalances. Thyroid disease is extremely common today, especially among young women and the elderly. As common as thyroid disease is, its symptoms are so similar to so many other ailments that it often goes unnoticed by both doctors and patients. If you’re suffering from fatigue, get your thyroid hormone levels checked.
Food Allergies. You may be allergic to common foods like dairy, eggs, nuts, wheat, corn, chocolate, or coffee. If you suffer from coughing or wheezing, digestive problems, headaches, muscle aches or joint pain, itching and skin problems, in addition to fatigue, try cutting out each of these foods for a week to see if you feel better without it. Also, don’t eat excessive amounts of any particular food during any one day.
Environmental Toxins. Fatigue may result from our polluted environment. If, in addition to fatigue, you suffer from headaches, allergies or respiratory problems, you may be absorbing airborne toxins. Check the ventilation system in your home and office. Buy houseplants, air filters, and water filters for your home. If you’re working in a “sick” building you may have to look for another job.
Couch Potato Syndrome. Fifty percent of depression and fatigue can be caused by inactivity. For an energy boost, do anything that gets you moving for 20 to 30 minutes a day.
Anemia. Anemia can be a hidden disease in women. If you’re tired for no known reason, have your total iron count taken. Sometimes, even though your blood count may show a normal level of red blood cells, you may still be deficient in iron. If your iron count is low, you may need supplements.
Cigarette Smoking. Cigarettes are an enormous energy drain. They rob the body’s cells of oxygen and produce carbon monoxide poisoning.
Too Much Coffee. If you drink a lot of coffee in the effort to beat fatigue, in the long run you’ll be even more tired. Coffee gives you a temporary lift at the cost of long-term energy.
Poor Nutrition. The typical American diet, high in refined foods and animal fat, supplies inadequate nutrients and drains energy. Switch to a diet low in animal protein and saturated fat and high in fruits, vegetables, grains and beans. Cut out highly processed foods. Take vitamins.
62. What does the underlined word “fatigue” mean?
A. tiredness B. weakness C. sickness D. laziness
63. Couch potato syndrome has something to do with ______.
A. potato B. couch C. energy D. inactivity
64. According to the passage, you can infer that ______.
A. you can always do with five or six hours of sleep a night.
B. fifty percent of depression and fatigue can be caused by inactivity.
C. it’s easier for women to catch thyroid disease or anemia.
D. the more coffee you drink, the less tired you are.
65. Which of the following is NOT one of the causes of fatigue according to the passage?
A. Polluted environment. B. Cigarette smoking. C. Low iron count.
D. A diet low in animal protein and saturated fat and high in fruits, vegetables, grains and beans.

Anxiety has now surpassed depression as the most common mental health disease among college students, though depression, too, is on the rise. More than half of students visiting campus clinics cite anxiety as a health concern, according to a recent study of more than 100,000 students nationwide by the Center for Collegiate Mental Health at Penn State. Nearly one in six college students has been diagnosed with or treated for anxiety within the last 12 months, according to the annual national survey by the American College Health Association.
The causes range widely, experts say, from mounting academic pressure at earlier ages to overprotective parents to engagement with social media. Anxiety has always played a role in the development of a student’s life, but now more students experience anxiety so acute that they are seeking professional help. Like many college clinics, the Center for Counseling and Psychological Services at the University of Central Florida (UCF)— one of the country’s largest and fastest-growing universities, has seen sharp increases in the number of clients: 15.2 percent over last year alone.
Anxiety has become characteristic of the current generation of college students, said Dan Jones, the director of Counseling and Psychological Services at Appalachian State University in Boone, N. C. Because of increasingly pressures during high school, he and other experts say, students arrive at college preloaded with stress. Accustomed to extreme parental oversight, many seem unable to govern themselves. And with parents so accessible, students have had less incentive to develop life skills. “They can’t tolerate discomfort or having to struggle,” Dr Jones said.
More often, anxiety is mild and temporary, the indication of a student under the control of a normal developmental issue-learning time management, for example, or how to handle rejection from a sorority. Mild anxiety is often treatable with early, modest interventions. But to care for rising numbers of severely troubled students, many counseling centers have moved to triage protocols (分诊措施). That means that students with less urgent needs may wait several weeks for first appointments.
Like many college counseling centers, UCF has designed a variety of daily workshops and therapy groups that implicitly and explicitly address anxiety, depression and their triggers. Next fall the center will test a new app for treating anxiety with a seven-module cognitive behavioral program, accessible through a student’s phone and augmented with brief videoconferences with a therapist. It also offers semester-long, 90-minute weekly therapy groups, such as “Keeping Calm and in Control”, “Mindfulness for Depression” and “Building Social Confidence” -for students struggling with social anxiety.
1.Which of the following contributes to anxiety according to the text?
A. Protection from teachers. B. An app in students’ phones.
C. Increasingly learning pressure. D. Management of time learning.
2.What does the underlined word “incentive” in Paragraph 3 probably mean?
A. Prevention. B. Motivation. C. Acquisition. D. Direction.
3.What’s the purpose of those therapy groups mentioned in the last paragraph?
A. To help students suffering anxiety.
B. To test what social anxiety is.
C. To introduce the cognitive behavioral program of UCF.
D. To emphasize the importance of calm and confidence.
4.Which of the following would be the best title for the text?
A. Tips on dealing with anxiety
B. Causes of anxiety and depression
C. Different mental diseases threaten college students
D. College mental health centers overburdened with anxious students

"Can I get a light?" This question is among the most common between smokers. What if this question was to come from an unusual source? In April 2014, the National Health Promotion Foundation uploaded an anti-smoking advertisement onto YouTube. The anti-smoking ad has quickly been known as the "most powerful anti-smoking ad."
The anti-smoking video, called the "Smoking Kid," features children walking up to adult smokers asking for a light. The children in the ad are actors but the adults smoking are unsuspecting participants in the project.
The video begins with the statement "adults know that smoking is harmful, but don’t remind themselves of this fact " Once a "smoking kid" approaches the adults, every adult asked is shocked that a child with a cigarette in hand is asking for a light. The first adult starts by saying, "I’m not giving it to you," and the video goes on to state "every adult filmed said no and reminded the children that smoking is bad."
Before going away, the kid hands each adult a booklet after being turned down for a light. The booklet says, "You worry about me, but why not about yourself?" Each adult looks around for the child as their faces are filled with confusion and discomfort.
The video shows that a few of the smokers quickly threw away their cigarettes or put their cigarettes away, showing that this experiment was affective at that moment.
The most influential element in the ad isn't the use of children or the responses from the smoking adults. It comes down to something much simpler than that. Why is it that we worry about other people, forgetting to worry about ourselves?
1. According to the text, the anti-smoking ad is ______.
A. unusual B. shocking C. influential D. encouraging
2.The underlined word "unsuspecting" (in Para. 2) probably means ______
A. uninformed B. unwilling C. unfortunate D. unacceptable
3. What are the adults,reactions to the children asking for a light?
A. They pay no attention to children's request.
B. They reject kids,request and educate them.
C. They look around for children's parents.
D. They quickly throw children's cigarettes away.
4.The best title of the text might be ______.
A. Give up smoking, for your own sake B. Keep away from smoking, adults
C. Tell your children not to smoke D. Reject a child asking for a light

Cell phone use and texting are increasingly common, especially among teens. And that could be a problem. Texting affects learning and performing on test, a new study finds. So a Montana teen, Colin decided to test that.
They asked 47 classmates to take part in a two-part experiment. The goal was to test how well these students understood written material. Each one had to read a paragraph or two about a certain topic, then answer questions about it.
In the first part, the participants had 15 minutes to understand and then answer questions about six readings. Throughout this test, they met no distractions.
During a new set of readings, the brothers sent messages to the participants’ cell phones every 90 seconds. In each message, there were questions that required a reply.
Participants should have scored better on the second test because it was easier. In fact, they scored worse when distracted by messages. Only a few students scored as well when replying to messages as they did when undistracted. But importantly, nobody performed better during the texting part.
The brothers presented details of their findings at the Intel International Science and Engineering Fair. Boys and girls scored equally poorly while texting, the brothers noticed. Older participants didn’t do any better than younger ones. And it didn’t matter if a student thought he was good at multitasking. On average, the brothers found that even students who were confident of their abilities did just as poorly while texting. Surprisingly, even though the students remembered less of what they read while texting, most of them answered questions in messages perfectly.
“Our teachers are very happy to see these results,” says Coler. The teens’ new data strongly support their teachers’ opinion that texting while studying is a serious distraction.
1. What did Colter and Colin want to test?
A. Cell phone use and texting are more common.
B. Teens should avoid cell phone use and texting.
C. Texting affects students’ performance on test.
D. The effect of texting differs from person to person.
2.What can we learn from the two-part experiment?
A. The written material in the two parts was the same.
B. Participants in part 2 received more than one message.
C. The time of the test in two parts was the same.
D. All the participants were distracted by messages.
3.The brothers’ findings were related to participants’ ________.
A. reading performance B. quality
C. writing ability D. reading speed
4. From the results of the experiment, we can find _________.
A. boys were better at multitasking than girls
B. the easier the tests were, the more mistakes were made
C. nobody did good jobs in the two-part experiment
D. some students’ test results were not affected by texting
5.What’s Colter’s teachers’ attitude toward the results?
A. Surprised. B. Worried.
C. Satisfied. D. Serious.
