Alaska’s Arctic lakes now freeze later and melt earlier in the year than in 1950，leaving them easy to suffer water loss from evaporation(蒸发)and possibly adding to local warming，a new study finds．The winter ice season near Barrow，Alaska，is shorter than in 1950，researchers reported Jan.30 in the journal The Cryosphere.
Lake ice is also thinner each winter．The scientists surveyed 402 lakes on the North Slope，where permafrost (permanently frozen ground)and shallow lakes dominate the areA． In 2011，the lake ice was 38 percent thinner than in 1950，and 22 percent fewer lakes froze through to their bottoms．
“When we saw the actual numbers we were shocked at how dramatic the change has been，”lead study author Cristina Surdu，of the University of Waterloo in Canada，said in a statement．Surdu and her co-authors analyzed the changes in lake—ice thickness and ice cover with satellite images and climate model simulations(satellite images are only available from 1991)．
The climate models suggest the Arctic lakes froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared with the winter of 1950．“The changes in ice and the shortened winter affect Northern communities that depend on ice roads to transport goods，”Surdu saiD． For example，every winter，oil companies build roads over frozen lakes to carry supplies to Prudhoe Bay．
“The dramatic changes in lake ice may also contribute to further warming of the entire region，because open water on lakes contributes to warmer air temperatures，”Surdu saiD． The Arctic is warming twice as fast as the rest of the planet，for reasons that may include its layered atmosphere，which traps heat，and the loss of sea ice and snow cover，which help reflect the sun’s energy when present．What does the text mainly tell us?
| A．Arctic 1akes now freeze earlier and melt 1ater． |
| B．Alaska’s local warming is decreasing sharply． |
| C．Arctic lakes are losing ice． |
| D．Arctic lakes hold more flesh water than before． |

| B．are completely within Surdu’s expectations |
| C．come as no surprise to Surdu and her co-authors |
| D．come as a great excitement to Surdu |

| A．6 days． |
| B．12 days． |
| C．18 days． |
| D．24 days． |
What is the last paragraph mainly about according to Surdu?

While it is impossible to live completely free of stress, it is possible to prevent stress as well as reduce its effect when it can’t be avoided. The US Department of Health and Human Services offers the following suggestions for ways to deal with stress.
Try physical activity
When you are nervous, angry or upset, try releasing the pressure through exercise or physical activity. Running, walking, playing tennis, or working in your garden are just some of the activities you might try. Physical exercise will relieve your anxiety and worry and help you to relax. Your body and your mind will work together to ease the stress in your life.
Share your stress
It helps to talk to someone about your anxieties and worries. Perhaps a friend, family member, teacher or even your leader can help you a better view of what’s troubling you. If you feel your problem is serious, you might seek professional help from a psychologist or a doctor. Knowing when to ask for help is an important step in avoiding serious problems later.
Take care of yourself
You should make every effort to eat well and get enough rest. If you easily get angry and cannot sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situations. If stress repeatedly keeps you from sleeping, you should consult a doctor. Make time for yourself.
Make a list of the things you need to do
Stress can result from disorganization and a feeling that "there’s so much to do, and not enough time". Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is completed. Set out to do the most important tasks first.
Go ahead and cry
A good cry can be a healthy way to bring relief to your anxiety. It might even help you avoid a headache or other physical effect of anxiety and stress. What is most probably the writer’s purpose in writing the article?
| A．To release his or her working tiredness. |
| B．To help solve the universal problem of stress. |
| C．To strengthen his or her anxiety. |
| D．To have more people cry out. |
Physical activity can help people release stress because________.
| A．only your body movement can help you relax |
| B．your mind can work better to free you of anxiety |
| C．your body and mind can cooperate in releasing stress |
| D．physical activity doesn’t play an important part in reducing nervousness |
What is similarity between "Share your stress" and "Go ahead and cry"?
| A．They both help you let out your feelings. |
| B．They both need physical movement. |
| C．They both require mental relaxation. |
| D．They can cause a headache. |
The underlined sentence is close to the meaning of "________".
| A．Strike while the iron is hot |
| B．More haste, less speed |

| D．Quietness wins time |
“Old wives tales” are beliefs lasting for many generations. For example, most of us remember our parents’ telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time.
Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic is good for you, too. It can kill the type of virus that causes colds.
Unfortunately, not all of Mom’ s advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems? Well, yes. However, sticky sweets made with grains tend to cause more problems than sweets made with simple sugars.
Even though science can tell us that some of our traditional beliefs don’t hold water, there is still a lot of truth in the old wives’ tales. After all, much of this knowledge has been accumulated from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false.Which of the following is TRUE according to the test?
| A．Eating garlic is good for our eyes. |
| B．Sticky sweets are damaging our teeth. |
| C．Swimming after a meal is dangerous. |
| D．Carrots prevent people from catching colds. |

| A．to be believable | B．to be valuable |
| C．to be admirable | D．to be suitable |
What is the author’s attitude toward “old wives tales” in the text?
| A．Subjective | B．Objective | C．Dissatisfied | D．Curious |
A young woman was diagnosed with a terminal illness（不治之症）and given three months to live. So as she was getting her things “in order”, she asked her pastor（牧师）to come to her house to discuss her final wishes. With everything in order, the pastor was ready to leave when the young woman suddenly remembered something very important to her.
“What’s that?” asked the pastor.
“I want to be buried with a fork in my right hand.”
The pastor stood looking at the young woman, not knowing what to say.
“That surprises you, doesn’t it?” the young woman asked.
“Well, to be honest, I’m puzzled by the request,” said the pastor.
The young woman explained, “In all my years of going to church meetings and dinners, I remember that when the dishes of the main course were being cleared, someone would always lean over and say, ‘Keep your fork.’ It was my favorite part because I knew that something better was coming, like chocolate cake or apple pie，some dessert like that. Something wonderful! I just want people to see me there in that casket（棺材）with a fork so that when they ask you why I have a fork, you can tell them: ‘Keep your fork—the best is yet to come.’”
The pastor hugged the young woman good-bye. He knew that the young woman had a better grasp of heaven than he did. She had a better grasp of what heaven would be like than many people twice her age, with twice as much experience and knowledge.
At the funeral people were walking by the young woman’s casket and they saw the pretty dress she was wearing and the fork placed in her right hand. Over and over, the pastor heard the question “Why does she have a fork?” And over and over again he smiled.
So the next time you reach down for your fork, let it reminded you of this young woman gently. Send the message to everyone you consider a friend even if it means sending it back to the person who sent it to you.

Scholars and researchers have tried to discover what personality characteristics go along with success in intercultural experiences. Their findings have often been unclear or incomplete. But three characteristics stand out in their reports: patience, a sense of humor, and the awareness of being unclear.
Patience, of course, is the ability to keep calm even when things do not go as one wants them to, or hopes they will, or has even been sure they will. Impatience sometimes brings improvements in relations with other people, but usually it does not.
A person with a sense of humor is less likely to take things too seriously and more ready to see the humor in her own reactions than a humorless person. The value of a sense of humor really needs to be paid more attention to.
“The awareness of being unclear” is a more difficult concept than patience or a sense of humor. Foreigners often find themselves in situations that are unclear to the newcomers. That is, they do not know what is happening in the situation. Perhaps they do not understand the local language well enough, or they do not know how some system or organization works, or they can’t be sure of different people’s roles in what is going on. “It’s like I just got here from the moon,” a Chinese graduate student who newly arrived in the United States said, “things are just so different here.”The passage mainly tells us .
| A．that it’s not easy to travel abroad |
| B．that humor is very important in communication |
| C．about some characteristics in dealing with foreigners |
| D．about three main ways useful for communicating with foreigners |
According to the passage, what characteristic should be most focused on?
| A．Patience | B．The awareness of being unclear |
| C．The sense of humor | D．Understanding each other. |
“The awareness of being unclear” refers to .
| A．knowing the meaning of an exact situation |
| B．not stating clearly what happens |
| C．realizing the possible misunderstanding in a situation |
| D．being aware of the unclear situation |
According to the writer, the Chinese students is .
| A．a hard-working student | B．recently back from the moon |
| C．interested in the study of moon | D．not used to the culture in America |
