With 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 Travel

Travel 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 Time

Grand 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 Awareness

Buffalo(水牛)often block the roads in the park as they move through the fields. If a group is traveling across 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.

Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.

Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.

Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陈代谢的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.

Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.

Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”

1.What contributes the most to one’s heart rates according to the first paragraph?

A．our bodyweight                        B．the consumption of energy

C．the rates of our breathing                 D．the amount of oxygen provided

2.Hormones are tested in the research because they can affect ______.

A．one’s bodyweight                      B．one’s blood pressure

C．one’s way of living                     D．one’s metabolic rate

3.What was found about the 20 overweight men in the process of the research?

A．They controlled what to eat self-consciously.

B．They took in much fewer calories than usual.

C．They lost appetite because of lack of physical activity.

D．They were provided with a healthier diet than before.

4.Why does Damian Bailey agree with the idea of appetite loss at high altitudes?

A．He experimented with the new weight loss plan in the Andes.

B．He found no other reasons for his loss of weight in the Andes.

C．He researched the related subject in the Andes.

D．He lost much weight in the high altitude Andes.

5.In what manner does Lippl talk about the way of losing weight by spending holidays on mountains?

A．casual            B．inaccurate         C．uncertain         D．confident

It’s interesting that the arrival of snow has effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others a catastrophe(灾害) or even a wonder.

　But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply causes problems. Within hours of the first snowfalls, however light, roads are blocked, trains and buses have to stop in the middle of the way. Normal communication is affected as well: telephone calls become difficult and the post immediately takes more time than usual. And almost within hours, there are also certain shortages----bread, vegetables and other things-----not because all these things can no longer be produced or sent to shops, but mainly because people are frightened and go out and store up with food and so on…just for fear that something bad should happen.

　But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don‘t have such problems. It is simple because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs(扫雪机) and machines to spread salt. The reason why a country like Britain does not buy snow-ploughs is that they are used for a few days in any one year, and the money could be more useful in other things such as hospital, education, helping the old and so on..

1.According to the writer, Britain is a country ________.

　2.After a few hours’ snowing there are often some shortages of food because ______.

　A. shops have closed down B. people buy as much as they can

　B. farmers cannot produce any more D. people eat more vegetables in winter

　3.The words "two kinds" in the passage mean the countries ______.
