Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people － up to 3 percent of the population － sweat too much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families － hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren’t sure what causes hyperhidrosis, but using special medications or other treatments can help.What caused the happening mentioned in the passage during Amanda’s running?
| A．She couldn’t breathe in enough air in the race. |
| B．She didn’t eat anything before the race. |
| C．She had been running all summer without a rest. |
| D．She neither drank enough water nor ate enough of the right kind of foods. |
What can we infer from Paragraph 4?
| A．There is no need to worry when sweating too much, even in cold weather. |
| B．Hyperhidrosis may have a bad effect on your health. |
| C．Doctors have discovered why people get hyperhidrosis. |
| D．Hyperhidrosis is a serious disease and no treatment can help. |
The purpose of writing this passage is to____________.
| A．tell teens the proper ways to take exercise in summer. |
| B．tell teens not to run in hot summer. |
| C．tell teens to pay attention to hyperhidrosis in the summer exercise |
| D．tell teens how to keep healthy. |
The new high-speed railway line between Urumqi，capital of the Xinjiang Uygur self-governing region，and Lanzhou，capital of Gansu province，has cut train travel time by half to less than 12 hours．
The dramatic improvement will benefit many families planning reunions for Spring Festival．
“For the first time，I feel home is not that far away after all，”said Liang Shaofu as he boarded a high-speed train in Urumqi with six members of his family．
The 35-year-old left Lanzhou to set up a dry fruit business in Xinjiang eight years ago，and he has now settled in Urumqi．
The 1,776-km line，which passes through Qinghai province and is the country’s first high-speed railway to be built in a high-altitude region，came into service on Dec 26．
“We normally drive home for Spring Festival to avoid the difficulties of buying seven train tickets for the whole family during the peak season，”Liang said．“Driving can be very tiring and dangerous sometimes，so one year we even decided not to go back to Lanzhou simply to avoid the trip．”
More than 600，000 passengers traveled on the line during its first month，and the Urumqi Railway Bureau said the introduction of high-speed services will ease transport pressure during the Spring Festival peak season．
The existing usual railway line could no longer support Xinjiang’s development．All passenger trains will gradually shift to the new link，leaving the old one to be used for goods．As a result，Xinjiang’s annual goods ability could reach 200 million metric tons from the current 70 million．
The line passes through areas that experience high winds，and it also crosses parts of the deserted Qinghai-Tibet Plateau and the bone-dry sands of the Gobi Desert．
The project could help China to promote its high-speed railway technology abroad，said Ma Xi zhang，director of the Lanzhou-Xinjiang railway project’s_management department in Xinjiang.How long did it take to go from Urumqi to Lanzhou by the usual train before?
| A．about 12 hours． | B．About 6 hours． |
| C．About 18 hours． | D．About 24 hours． |
What’s the main advantage of the new high-speed railway?
| A．It takes more time to go to Urumqi to Lanzhou． |
| B．It will be more convenient for people all over the country to Xinjiang． |
| C．All the people in Lanzhou can return home on festivals． |
| D．It helps to improve Xinjiang’s development． |
From the passage we can learn________.
| A．Xinjiang’s annual goods ability can increase nearly four times |
| B．the new railway technology may help more railway lines to be built abroad |
| C．the high-speed railway lines can’t be built across the bone-dry sands |
| D．the old railway lines can only carry goods now |
Which of the following is true according to the passage?
| A．The new high-speed railway line is good for all people to go home． |
| B．The new high-speed railway line benefits businessmen to carry goods． |
| C．Taking the new train is safer than driving home from Urumqi to Lanzhou． |
| D．Businessmen seldom went home for Spring Festival before． |
What are American high schools like? Well，I'm happy to tell you what I know．
When I started school here，it had already been a week since the schoo1 opened．At this school，freshmen usually go on a trip for about three days at the beginning of school. Unfortunately I missed that wonderful trip．which would have been the best time to get to know my classmates．I was really sad．I wished I’d known about it earlier.
Despite the disappointment，however，I gradually adapted to my new life and schoo1．
There is a space in the basement of the teaching building where students chat and meet each other．As we do not always have the same classrooms and classmates，the school wants us to get to know each other there．Students usually come to school early，sit in that space and have fun．Around the space，there are many lockers for students to leave their books in，so that students do not have to carry a heavy schoolbag everywhere．
It really surprises me that we have almost no textbooks．We only have textbooks for World History and Algebra and they are big and heavy，like bricks．For other classes，we only need binders(活页夹)with paper in them．Without textbooks，students learn things freely and actively．For example，my humanities teacher just teaches us what is in her mind at the time．We never know what we will learn．
Another difference between American schools and Chinese schools is that American schools care about students’ morality more than their academic studies．For example，if you do not finish your homework，you will just be asked to do it later，but if you cheat or lie，you will get a warning or even be kicked out．
I think that most students here are good at schoolwork as well，but compared to Chinese students，they can make learning a more joyful experience．I think we should take the good points from our two different kinds of education to perfect our approach to studying．What was the writer sad for?
| A．He was late for schoo1． |
| B．He missed the trip at the beginning of schoo1． |
| C．He didn’t know anyone． |
| D．American students looked down upon him． |
Why do students go to the basement of the teaching building?
| A．To attend class． | B．To share a classroom． |
| C．To have fun． | D．To meet teachers． |
According to the passage，in American high schools，_________．
| A．you are likely to be kicked out if you cheat |
| B．you’11 be punished if you do not finish your homework |
| C．students are better at school work than Chinese students |
| D．students care much about the grades they get |
I believe that my country，Poland，is a perfect example for a place where food is particularly important. When we were little children, we began to understand how much a loaf of bread meant to our parents—to some it might sound silly but for me the custom of kissing bread before you started cutting it was simply amazing. It’s not so common nowadays to treat food that way，since you hardly ever bake your own bread. Besides, everyone would call you crazy if you tried to kiss every bread roll before you ate them! But though we no longer make our food from scratch (起点), some customs have been kept—that’s why I feel so sorry every time I have to throw any food away—even though I no longer live with my parents and nobody would blame me for this anymore!
Many people of our nation are still working as farmers, eating what they grow and harvest and therefore enjoying everything more. It’s widely known that you value more anything that needs your effort in the first place. In most homes in Poland, especially those of farmers, the whole family would try and have their meals together—extremely difficult now, but so rewarding! You can share other members’ troubles and successes, give your children some attention, or just sit down for a moment, instead of rushing through life aimlessly. Furthermore, your body，and stomach in particular will be very grateful for such a time!
In Poland, a wedding，Christmas or even a birthday is celebrated with a great meal. Women in the house get together and cook ,sometimes for a few days before the event，and the extremely good or unusual food will be remembered and widely talked about.
You cannot over-value the importance of food in the country. What’s more, almost everyone in Poland will be as interested in the topic as I am.When the writer was a child, he/she _______.
| A．found people were crazy about bread |

| D．learned people hardly baked their own bread |
The writer feels very sorry when he/she has to throw away any food because___________.
| A．he/she makes food from scratch |
| B．his/her parents would blame him/her |
| C．some customs still have effect on him/her |
| D．many people are still working hard as farmers |
From the text, we can learn that, in Poland, ________.
| A．most meals can be interesting topics for a long time |
| B．the whole family often have meals together nowadays |
| C．it’s common for women to get together to cook for a few days |
| D．family members can know more about each other by having meals together |
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 quite! 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! What did the author’s classmates think about his report?
| A．interesting | B．ridiculous. |
| C．boring. | D．puzzling. |
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. |
The underlined word “burning” in Para. 3 probably means _______.
| A．annoyed | B．ashamed | C．ready | D．eager |
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 |
Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer’s crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn’t tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.We know from the passage that elephants may be frightened of .
| A．loud noises | B．some crops |
| C．video cameras | D．angry bees |
As mentioned in the passage, Lucy .
| A．works by herself in Africa |
| B．needs to test more elephant groups |
| C．has stopped elephants eating crops |
| D．has got farmers to set up beehives on their farms |
Why did Lucy throw a stone into a wild beehive?
| A．To record the sound of bees. |
| B．To make a video of elephants. |
| C．To see if elephants would run away. |
| D．To find out more about the behavior of bees. |
Which of the following is true according to the passage?
| A．Young elephants ignore African honeybees. |
| B．Waterfalls can make elephants stay in one place. |
| C．Elephants do not go near trees with bees living in them. |
| D．Farmers do not allow Lucy to conduct tests in their fields. |
