AWith its snow-covered mountains and a variety of wildlife, Yellow Stone National Park is one of the scenic treasures of the United States. Located primarily in Wyoming, the park hosts millions of visitors every year. If you plan to travel within the park, keep in mind advice from the National Park Service.Seasonal TravelTravel varies vastly from season to season. Roads are generally open in the summer except for cases of rock or mud slides, wild fires, accidents or road construction. Early snows in the fall can cause some roads to close temporarily. In the winter almost all roads are closed to motor vehicles, but snowmobiles and other snow vehicles with tracks are allowed. Roads begin to open for the spring by the latter part of April but can close if snowfall continues.Driving TimeGrand Loop is the main road through Yellowstone National Park; it passes by most of the major attractions. These include Old Faithful, Yellowstone Lake and the Grand Canyon of Yellowstone. The maximum speed limit on the Grand Loop is 45 miles per hour, but the speed limit drops during some of the winding and twisting sections of this narrow road. Allow yourself at least two days to fully travel the loop due to the size of the park and being sometimes stuck in heavy traffic.Safety AwarenessBuffalo(水牛)often block the roads in the park as they move through the fields. If a group is travelingacross the road you are on,you can either wait for them to pass or find an alternative route. If you get out of your vehicle, the National Park Service says to stay at least 25 yards from any buffalo (and 100 yards or more away from bears and wolves). Buffalo are particularly unpredictable and charge people at speeds up to 30 mph.You can take your bicycle on any public roads and routes designed for bikes, but bicycles are not allowed on the park roads which are narrow with few shoulders. Altitudes range from 5, 300 to 8, 860 feet. The National Park Service recommends cyclists wear helmets and noticeable clothing.1. What do we know about travelling in the Yellowstone Park?A. Roads will stay open in case of emergency.B. Traffic jam happens from time to time.C. The driving speed on the road can be 50 mph.D. Motor vehicles are allowed in the winter.2. What does the National Park Service suggest people do about safety?A. Stay inside the car throughout the travel.B. Get out of their vehicles when coming across the Buffalo.C. Wear the easy-to-see clothes while bicycling.D. Avoid bicycling on the public roads.3. From which is the text probably taken?A. A guidebook.B. A commercial advertisement.C. A research paper.D. A geography textbook.BMost adults firmly believe that as kids reach their teens, they start to take crazy risks that get them in trouble. Do teenagers simply love taking all risks much more than adults? A recent study suggests otherwise.Scientists designed a simple experiment involving 33 teenagers and three other age groups. In the experiment, the researchers tried to distinguish between two very different kinds of risk-taking. The first they called a willingness to take known risks (when the probability of winning is clear) and the second they called a willingness to take unknown risks (when the possibility of success is uncertain).The study offered participants the opportunity to play two kinds of games. They had the chance to winmoney, with one game offering a known risk and the other offering an unknown risk. On each round of the game, each participant had to choose between taking a sure $5 and known or unknown risks of winning a lot more. If on one particular round they had picked the $5 for sure choice, then they got $ 5. But if on that round they had chosen to take a risk, the rules of the game will determine whether or not they had won. If they did win, they went home with between $8 and $125. And, of course, if they lost, they went home with nothing.What the scientists found was really quite surprising. It turned out that the average teenager was very hesitant when risks were known—more careful than college students or parents-aged adults, and about as careful as grandparent-aged adults. This means that when the risks were known, teenagers were not risky in their behavior at all. Only when the risks were unclear did teenagers choose them more often than other groups. Under those kinds of conditions, they were much more willing to take a risk than any other group.So, what does all of this mean? The research suggests that adults should probably focus more energy on trying to educate teenagers about risks than limiting them. Teenagers who understand the risks associated with a decision are more likely to be careful in their behavior.4. This experiment was carried out byA. dividing the teens into three groupsB. comparing the reactions to different risksC. giving equal amount of awards to the participantsD. observing the emotional changes of the teenager5. When facing known risks, teenagers tended to be ________.A. ambitsB. cautiousC. anxiousD. curious6. Which group in the study were more likely to take unknown risks?A. Teenagers.B. College students.C. Parent-aged adults.D. Grandparent-aged adults.7. According to the study, parents should focus on ________.A. guaranteeing children to be carefulB. setting age limits on dangerous activitiesC. respecting teens to make their own choicesD. guiding teens to learn more about the effect of risksCTrees, some of the tallest in the world, towered above Hannah Griffiths and her colleagues eachmorning as they walked deep into the rainforest in the Maliau Basin in Borneo, where they had set up a setof experiments to look at the ecological effects of small creatures: termites (白蚁).Termites get a bum rap. They make headlines for chewing up billions of dollars of property each yearin the U. S. And they are responsible for something like two percent of global carbon emissions, simply asa result of their huge populations and preference for chewing through carbonrich materials. A wholeindustry is aiming at killing them.But they play a key role in many natural ecosystems. Scientists have known for years that in tropical(热带的) forests, termites chew up fallen leaves and dead wood, keeping the fallen material under controland letting nutrients from the dead material back into the system to be used by other plants, insects, andtant the insects were in keeping the forest healthy andanimals. But they didn’t know exactly how imporfunctional, so they removed termites from a particular spot in the forest and saw how it responded.As luck would have it, Hannah Griffiths and her colleagues started their experiment when the forestwas hit by an extreme drought (干旱). During the non-drought years, they saw there wasn’t muchdifference between the normal plots and the ones where they’d removed the termites. But during the drought, the effects were marked. What they found was unexpected: in the termite-rich areas, the soilstayed slightly wet, more tree seedlings sprouted (抽芽), and the system was full of activity despite the long,hard dry spell.For Griffiths, it was only because they happened to study the drought that they could pick out the realimportance of termi tes to the system, she points out. “And that rings alarm bells in my head,” s “because it makes me think, well what else don’t we know? If we start damaging biological communities, we don’t know what that will do.”8. Which of the following best ex plains “a bum rap” underlined in Paragraph 2?A. Unfair blame.B. Wide popularity.C. Public attention.D. Special preference.9. What have scientists learned about termites?A. They do serious harm to tropical rainforests.B. They contribute a lot to the ecosystem they live in.C. They act as food for other plants, insects and animals.D. They speed up the loss of nutrition in the rainforest.10. What can we infer from the finding of Griffiths experiment?A. Termites help rainforests survive climate change.B. Termites prefer drought years to non-drought ones.C. Termites benefit more from the forest during the drought.D. Termites enjoy eating tree seedlings during the drought.11. What does Griffiths tell us in the last paragraph?A. Termites are now in danger of extinction.B. Termites damage biological communities.C. We should think twice before damaging a species.D. We should study the drought to improve the system.DIf humans pump enough carbon dioxide (CO2) into the atmosphere, the stratocumulus clouds(层积云) could disappear, and the earth's temperature could climb sharply to heights not predicted in current climate models. It would burn the planet. That's the conclusion of a paper published in the journal Nature Geoscience and described in detail by Natalie Wolchover for Quanta Magazine.As Wolchover explained, clouds have long been one of the great uncertainties of climate models. Computer models that easily capture the complexity and detail of most climate systems just aren't powerful enough to predict worldwide changes in cloud behavior. But clouds are important. They reflect sunlightaway from the earth's surface. And stratocumulus clouds are those white blankets you might have seen as you looked out the window of arm airplane, rolling out below you and hiding the ground Researcherssuspect that certain sudden, past jumps in temperature may have been caused by changes to clouds like these.For the new research, scientists modeled just a small patch of sky using a supercomputer. They found that if carbon dioxide levels reach about 1, 200 parts per million(ppm) in the atmosphere, stratocumulus clouds break up. That's a very high carbon dioxide concentration. Right now, levels have climbed past410 ppm--a dangerous change from 280 ppm before the Industrial Revolution.But humans put more and more CO2 into the atmosphere every year. If current trends continue, the earth could reach 1, 200 ppm within 100 to 150 years. This could happen if our society doesn't followthrough on any of its commitments to reduce emissions(排放), Wolchover reported. And even if it does, theresult would be another 8 degrees Celsius of heat added to the global average, on top of the dangerous changes already underway due to greenhouse gases.ions of worldwide ice melt and catastrophic sea That’s an enormous change, and it goes beyond predictlevel rise. And, once the stratocumulus clouds are gone, Wolchover reported, they likely wouldn't reappear until atmospheric carbon dioxide levels dropped below where they are currently.There's still some uncertainty in the data. The 1, 200 ppm figure could change as scientists look into the issue further.12. What can we learn from paragraph 2?A. Most climate systems are not complex.B. Cloud behavior is uncertain and hard to predict.C. Temperature changes affect the stratocumulus clouds.D. The stratocumulus clouds protect planes from sunlight.13. How did the scientists study clouds in the new research?A. By measuring the sea level.B. By experimenting in a natural state.C. By comparing climate models.D. By computer modeling and analyzing.14. What does "it" refer to in paragraph 4?A. The atmosphere.B. The earth.C. Our society.D. The result.15. Which of the following statements would Wolchover most probably agree with?A. The effects of CO2 emissions have been fully assessed.B. The stratocumulus clouds won't return if they are gone.C. The breakup of stratocumulus clouds could result in catastrophes.D. Once CO2 level reaches 1, 200 ppm, stratocumulus clouds will go extinct.第二节(共5小题;每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
