8、that would see the Pacific Gas and Electric Company buy 200 megawatt (兆瓦) of power beamed down from solar-power satellites beginning in 2016. But some major challenges will have to be overcomed if the technology is to be used widely.A start-up company called Solaren is designing the satellites, whic

9、h it says will use radio waves to beam energy down to a receiving station on Earth.The attraction of collecting solar power in space is the almost uninterrupted sunshine available in eosynchronous (与地球同步的) orbit. Earth-based solar cells, by contrast, can only collect sun light during daytime and whe

10、n skies are clear.But space-based solar power must grapple (努力克服) with the high cost per kilogram of launching things into space, says Richard Schwartz of Purdue University in West Lafayette, Indiana, “If youre talking about it being economically viable or power of the Earth, its a tough go.“ he say

11、s.Cal Boerman, Solarens director of energy services, says the company designed its satellites with a view to keeping launch costs down. “We knew we had to come up with a different, revolutionary design, “ he says. A patent the company has won describes ways to reduce the systems weight, including us

12、ing inflatable minors to focus sunlight on solar cells, so a smaller number cancollect the same amount of energy.But using minors introduces other challenges, including keeping the solar cells from overheating, says Schwartz. “You have to take care of heat dissipation(散发)because youre now concentrat

13、ing a lot of energy in one place,“ he says. According to the companys patent, Solarens solarcells will be connected to radiators to help keep them cool.Though Boerman says the company believes it can make space-based solar power work, it is not expecting to crowd out other forms of renewable energy.

14、 Laws in California and other states requireincreasing use of renewable energy in coming years, he points out. “To meet those needs, were going to need all types of renewable energy sources,“ he says.（分数：7.00）(1).Solar-power satellites will use radio waves to beam energy down from space.

19、rs. Apple released the IPad in April 2010, and sold 3 million of the devices in 80 days.2. The iPad runs the same operating system as iPod Touch and iPhone. It can run its own applications as well as ones developed for iPhone. Without modification, it will only run programs approved by Apple and dis

20、tributed via its online store.3. Like iPhone and iPod Touch, the iPad is controlled by a multitouch display-a break from most previous tablet computers, which uses a pressure-triggered stylus (触控笔). The iPad uses a Wi-Fi data connection to browse (浏览) the Internet, load and stream media, and install

21、 software. Some models also have a 3G wireless data connection which can connect to GSM 3G data networks. The devices is managed and synchronized (同步) by iTunes on a personal computer via USB cable.4. An iPad has different features and applications one can use to execute different and interesting th

22、ings. There are lots of iPad applications that the owner can use to enhance the way they communicate. Some of these are how to use social networking sites and other online options. One of the most common uses is for e-mail services, ipand applications like Markdown Mail allow the adoption of specifi

23、c and particular options. They enable the owner to personalize their email accounts.5. While the iPad is mostly used by consumers it also has been taken up by business users. Some companies are adopting iPads in their business offices by distributing or making available iPads to employees. Examples

24、of uses in the workplace include lawyers responding to clients, medical professionals accessing health records during patient exams, and managers approving employee requests.

The method forecaster chooses depends up

28、on the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents, and the degree of accuracy or confidence needed in the forecast.The first of these methods is the persistence method; the simplest way of producin

29、g a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 87 degree today, the persistence method predicts that it will be sunny and 87 degree tomorrow. If two inches of rain fell today, the persistence method would

30、predict two inches of rain for tomorrow. However, if weather conditions change significantly from day to day, the persistence method usually breaks down and is not the best forecasting method to use.The trends method involves determining the speed and direction of movement for fronts, high and low p

31、ressure centers, and areas of clouds and precipitation. Using this information, the forecaster can predict where he or she expects those features to be at some future time. For example, if a storm system is 1,000 miles west of your location and moving to the east at 250 miles per day, suing the tren

32、ds method you would predict it to arrive in your area in 4,days. The trends method works well when systems continue to move at the same speed in the same direction for a long period of time. If they slow down, speed up, change intensity, or change direction, the trends forecast will probably not wor

33、k as well.The climatology method is another simple way of producing a forecast. This method involves averaging weather statistics accumulated over many years to make the forecast. For example, if you were using the climatology method to predict the weather for New York City on July 4th, you would go

34、 through all the weather data that has been recorded for every July 4th and take an average. The climatology method only works well when the weather pattern is similar to that expected for the chosen time of year. If the pattern is quite unusual for the given time of year, the climatology method wil

35、l often fail.The analog method is a slightly more complicated method of producing a forecast. It involves examining todays forecast scenario and remembering a day in the past when the weather scenario looked very similar (an analog). The forecaster would predict that the weather in this forecast wil

36、l behave the same as it did in the past. The analog method is difficult to use because it is virtually impossible to find a predict analog. Various weather features rarely align themselves in the same locations they were in the previous time. Even small differences between the current time and the a

37、nalog can lead to very different results.（分数：15.00）(1).Which of the following is NOT mentioned in choosing a forecasting method? A. Necessary amount of information. B. Degree of difficulty involved in forecasting. C. Practical knowledge of the forecaster. D. Creativity of the forecaster.（分数：3.00）A.B

38、.C.D.(2).The persistence method fails to work well when _. A. it is rainy B. it is sunny C. weather conditions change greatly D. weather conditions stay stable（分数：3.00）A.B.C.D.(3).The trends method works well when _. A. weather features are defined well enough B. predictions on precipitation are acc

39、urate C. weather features are constant for a long period of time D. the speed and direction of movement are predictable（分数：3.00）A.B.C.D.(4).The analog method should not be used in making a weather forecast when _. A. the current weather scenario is different from the analog B. the analog looks compl

40、icated C. the analog is more than 10 years old D. the current weather scenario is exactly the same as the analog（分数：3.00）A.B.C.D.(5).Historical weather data are necessary in _. A. the climatology method and the analog method B. the persistence method and the trends method C. the trends method and th

41、e climatology method D. the persistence method and the analog method（分数：3.00）A.B.C.D.六、B第二篇/B(总题数：1，分数：15.00)The IcemanOn a September, day in 1991, two Germans were climbing the mountain between Austria and Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that hei

42、ght (10,499 feet, or 3,200 meters), the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual and so the body had come to the surface.It was lying face downward. The skeleton (骨架) was in perfect condition except a wound on the head. There ar

43、e still on the bones and remains of some clothes. The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots. Nearby was a pair of gloves made of tree bark (树皮) and a holder for arrows.Who was the man? How and when had he died? Everybody ha

44、d a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in this area. A Swiss woman who believed it might be her father, who had died in those mountains twenty yea

45、rs before and whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousand years old.With modern dating techniques, the scientists soon learned that the iceman was about 5,300 years old. Born in about 3300 B.C., he lived dur

46、ing the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story. A new kind of X-ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, bu

47、t it caused internal damage and bleeding. He almost certainly died from this wound, and not from the wound oil the back of his head. This means that he was probably in some kind of battle. It may have been part of a large war, or he may have been fightiing bandits. He may even have been a bandit him

48、self.By studying his clothes and tools, scientists have already learned a great deal from the Iceman about the times he lived in. we may never know the full story of how he died, but he has given us important clues to the history of those distant times.（分数：15.00）(1).The body of the iceman was found in the mountains mainly
