Hypothermia can be mild, moderate or severe. Mild hypothermia is something that most people in cold climates have experienced at one time or another. You feel so cold that your body starts to shake---not very much, but uncontrollably.
The treatment for mild hypothermia starts with getting out of the cold and, if necessary, changing into dry clothes. Drinking warm, non-alcoholic liquids and eating something sugary can stop the shivering. Taking a warm bath or sitting by a fire or doing some exercise can also help the body warm up. These are all common-sense treatments.
But treatment needs to change when people enter the moderate or severe stages of hypothermia. In that situation, their body temperature drops below thirty-five degrees Celsius. They lose the ability to think clearly. Their muscles become stiff. They might bump into things or fall over objects.
Members of search-and-rescue teams will first try to prevent additional heat loss. They will place extra covering around the chest, head and neck of hypothermia victims to keep them warm.
Hypothermia victims need medical help as soon as possible. Working quickly to get people out of the cold is important. However, hypothermia victims must be moved slowly and gently. Any rough or sudden movement can force cold blood from the arms, legs and hands deep into the warmer middle of the body. This sudden flow of cold blood can create shock, a serious condition. It can also cause an abnormal heartbeat.
Members of search-and-rescue teams have a saying that hypothermia victims are not dead until they are warm and dead. The process of "rewarming" a person needs to be done slowly, in a hospital setting.
An extremely low body temperature can cause the heart to beat so slowly that a pulse may be difficult to find. In other words, a person who is suffering from the effects of severe cold may seem dead, but still be alive.
1.According to the text, when a person experience mild hypothermia, _____.
A. he feels cold so he shakes deliberately.
B. he can drink some wine to stop the shaking.
C. he should be sent to the hospital immediately.
D. some common treatments can help him recover.
2.Which of the following expression can take the place of the underlined words?
A. break into B. break down
C. knock into D. sweep up

A. If hypothermia isn’t treated correctly, the victim’s heart may not beat normally.
B. Their body temperature drops below 35℃.
C. Hypothermia victims seem alive but dead.

A headache is the feeling you get when your head hurts. Headaches can differ from very mild to incredibly powerful. They can last anywhere from 10 minutes to hours. Very bad headaches are called migraines. People who suffer from migraine headaches often need to take the day off from school or work and lie in bed all day.
Why do people get headaches? There are many possible causes. People who drink too much caffeine (in coffee or soft drinks, for example) or alcohol can end up with headaches. This is because these kinds of drinks take water away from the body. If the brain doesn’t have enough water, it gets smaller and pulls away from the head. This can be extremely painful. The best way to get rid of this kind of headache is just to drink lots of water.
Tension headaches happen when the body's muscles are too tight. When people feel stress, it is common for the muscles near the head to become tense. Tension headaches might also be caused by not getting enough sleep. Some people suffer from tension headaches for only short times but for other people, these kinds of headaches are a chronic problem that happens again and again. A massage (按摩) might help to stop a tension headache. If that doesn't help, you might need to see a doctor.
Headaches can also be caused by much bigger health problems. For example, a head or neck injury can cause them. Headaches can also be a warming sign of a heart attack.
1.In the article, how long can a headache last?
A.at least 10 hours. B.about 10 minutes.
C.from minutes to hours D.more than 10 hours.
2.Why can caffeine cause headaches?
A.Because it makes the head gets smaller.
B.Because it makes the skull gets bigger.
C.Because it takes water away from the body.
D.Because it gives the body too much water.
3.The word ''chronic'' in paragraph 3 have the same meaning with______.
A.terrific B.repeated
C.rare D.interesting
4.Why should someone with lots of headaches visit a doctor?
A.They might need to drink water. B.They might need to talk.
C.They might have a bigger problem. D.They might need more medicine.

Tests can be stressful even for the best students. 1. Fortunately, there are several steps you can take to make your stress much more manageable.
Get Enough Sleep
Getting 6 hours of sleep or less can put you into what's called a sleep deficit(不足),which makes you less sharp mentally and prevents you from performing properly on tests. 2. This way, you needn't stay up for the test and can get a good night of sleep before your big day.
Study Smarter
3. Make a list of the most important things you need to learn and hit the items at the top of the list first. This will ensure they're mostly covered if you run out of time. Make a list of all the work you have to do, estimate how long each item will take, and compare that with the amount of hours you have available. This will tell you if you can carefully read or just skim, how many times you can afford to revise the papers.
Visualize(想象)Success
A proven way to build your confidence is to visualize yourself taking the tests and doing wonderfully. Visualization can not only help you perform better in the tests but can help you remember facts. You can create detailed situations that involve the information you're trying to remember. 4.
Stay Calm
There're several techniques that can help you calm down quickly.5. Just close your eyes, take a deep breath, hold it for a while and then let it out slowly. Your stress will come out with your exhales(呼气).
A. Be organized with your studies.
B. Extra time on tests can bring success to students.
C. Test anxiety has a negative impact on your performance.
D. In this process you can strengthen the facts in your memory.

People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals(个人;个体), according to a new analysis of nearly 100 international studies.
The studies, most conducted within the past decade, included about three million adults from around the world. The result of these studies by researchers at the National Center for Health Statistics in Maryland, part of the U.S. Centers for Disease Control and Prevention, shows that slightly overweight or obese people were six percent less likely to die from all causes compared to people of normal weight. But the researchers found that seriously obese individuals were still at a 30 percent greater risk of death compared to healthy-weight individuals.
Study lead author Katherine Flegal says she was not surprised that overweight people would not have a higher death risk. “Because we'd actually already read a lot of this literature and realized that death rates for overweight would be at least not higher than normal[weight," she said. “I guess l was a little bit surprised that it was definitely lower. And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight."
But Flegal stresses the difference in death rates appear to be small between normal-weight people and overweight and mildly obese individuals.
The finding by Flegal and colleagues have raised new questions about the reliability(可靠性)of the so-called "body mass index" or BMI, a measurement of body fat as a ratio(比例,比率)of height to weight, that has become popular in recent years among public health experts to measure potential health risks.
But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms, since being at a healthy weight lowers the risk for heart disease and diabetes.
1.Katherine Flegal feels surprised at the fact that____.
A. obese people have higher death rates
B. slightly obese people have lower death rates
C. obese people tend to die early
D. death rates have nothing to do with body weight
2.What do we learn from the fifth paragraph?
A. BMI may not be so reliable.
B. The study provides further evidence for BMI.
C. BMI tells nothing about potential health risks.
D. BMI has been much questioned recently.
3.What can we conclude from the passage'?
A. It's OK to put on extra weight.
B. It doesn't matter if you are slightly obese.
C. Obese people are much healthier.
D. Body weight has nothing to do with death rates.
4.What topic does the passage mainly deal with?
A. Technology. B. Dieting. C. Health. D. Death.

Several recent studies have found that being randomly assigned(分配) to a roommate of another race can lead to increased tolerance but also to a greater likelihood (可能性) of conflict.
Recent reports found that lodging with a student of a different race may decrease prejudice and force students to engage in more ethnically diverse friendships.
An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.
In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove."
Researchers also observed problems resulting from pairing interracial students in residences.
According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out.
An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester.
Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said.
At Penn, students are not asked to indicate race when applying for housing.
"One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration (融合)."
"I've experienced roommate conflicts between interracial students that have both broken down prejudices and reinforced prejudices," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合)," there were also " cultural conflicts."
The RA said that these conflicts have also occurred among roommates of the same race.
Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained.
1.What can we learn from some recent studies?
A.Conflicts between students of different races are unavoidable.
B.Students of different races are prejudiced against each other.
C.Interracial lodging does more harm than good
D.Interracial lodging may have diverse outcomes.
2.What does Sam Boakye's remark mean?
A.White students tend to look down upon their black peers
B.Black students can compete with their white peers academically
C.Black students feel somewhat embarrassed among white peers during this year
D.Being surrounded by white peers motivates a black student to work harder to succeed.
3.The Indiana University study implies that______.
A.interracial roommates are more likely to part
B.roommates of different races just can't get along
C.few white students like sharing a room with a black peer
D.assigning students’ lodging randomly is not a good policy
4.What does Alec Webley consider to be the “definition of integration”?
A.Students of different races are required to share a room
B.Interracial lodging is arranged by the school for freshmen.
C.Lodging is assigned to students of different races without exception.
D.The school assigns roommates without regard to race.
