North Pole Explorations
If Santa Clans really does reside at the North Pole, he must live a lonely life. The North Pole isn't what most of us would consider a hospitable place as the average winter temperature there is 40 degrees below zero Fahrenheit (华氏温度) (-40 Celsius). And while Santa's reindeer are considered Arctic animals, not much life actually calls the North Pole its permanent home.
For adventurers, the North Pole is comparable to outer space: an unknown frontier that's ripe for exploration--and exploitation. The region doesn't belong to any one country, so there are always disputes about who can lay claim to the untapped natural resources there. And although the prospect of melting ice around. the North Pole isn't pleasant from a global warming standpoint, it could make those resources easier to reach.
North pole location
There are two North Poles. The one most people think of is the geographic North Pole, which is located approximately 450 miles (724 kilometers), north of Greenland, at 90 degrees north latitude. The magnetic North Pole is based on the Earth's magnetic field and is slowly drifting across the Canadian Arctic.
Because all lines of longitude converge (向中聚集) at the North Pole, it's not technically in any time zone (or, it's in every time zone, del)ending on your perspective). As a result, we generally use Coordinated Universal Time (UTC) at the. North Pole. Coordinated Universal Time is used mostly in astronomy and navigation: It's similar to Greenwich Mean Time (the time kept on the Greenwich meridian, longitude zero) but scientifically more precise.
The sun sets at the North Pole in early October. The next sunrise is in early March. In between, there's a continuous twilight as the Earth moves on its axis. As a result of all this, the North Pole is obviously cold. In the winter, when the North Pole is farthest from the sun on the Earth's axis, the average temperature is -40 degrees Fahrenheit (-40 Celsius) during December and January, but can dip into the negative 50s. The seawater beneath the ice of the North Pole is a relatively mild-28 degrees F (-33 C). In the summer, the Pole averages 32 degrees F (0 C). But the North Pole isn't as cold as it used to be.
History of North Pole expeditions
People have always had the desire to explore new plies. Explorers throughout history have been motivated--at least in part--by the promise of fame and fortune, and North Pole exploration is no exception. The first North Pole explorers were in search of the Northwest Passage, a route through the Arctic that would create easier trade--and great wealth--for the country that discovered it. When these explorers came back with tales of diamonds and coal near the Pole, the world started seeing the Arctic as a frozen treasure chest. In fact, a U. S. Geological Survey estimates that nearly 25 percent of the world's undiscovered oil and gas are buried in the Arctic, which is a big reason for the disputes among the countries that are eager to claim the region for themselves.
There were occasional North Pole expeditions in the 18th century (in 1755, the British Parliament offered a reward to the first ship to come within a degree of the Pole), but it wasn't until the early 1900s that things really got going. In 1908, American Frederick Albert Cook was the first person to claim to have reached the North Pole. But his countryman Robert Edwin Peary, with support from Cook's traveling companions, disputed the claim, and Cook was widely discredited.
Peary (with a team of 24 men, 19 sledges and 133 sled dogs) ended up making the first undisputed visit to the North Pole on April 6, 1909. But there's still some controversy attached to the claim, mostly because of Peary's improbable 37-day time frame. Most expeditions of the era took months--at least--to come close to the goal. However, in April 2005, explorer
A．it delivers an undisturbed home for many animals
B．most creatures cannot adapt to its environment
C．only Santa Claus likes living there with his reindeer
D．only a few kinds of creatures can't bear its coldness

听力原文： Last April, American businessman Dennis Tito reportedly paid between twelve-million and twenty-million dollars to spend one week on the International Space Station. NASA had strongly objected to the Russian plan to permit a civilian on the costly research vehicle. After two years of negotiations, space officials have agreed on a process to train private citizens to take trips to the International Space Station.
NASA recently agreed to conditions that will permit Russia to sell trips to the space station. An American company called Space Adventures Limited of Arlington, in Virginia plans the trips. Experts say the change in policy at NASA shows a new desire to use space vehicles for business and industrial purposes. In a speech to Congress last year, NASA official Michael Hawes said that the space agency had not considered civilian travel as one of the industries it wanted to develop. However, Mister Hawes said that private space travel could now be done as long as safety measures are observed carefully.
Candidates for adventure space travel trips must be in excellent health and must pass difficult health tests. They must receive a lot of training. However, Special English can help you prepare for a space holiday. This is because all successful candidates who wish to travel to the International Space Station must be able to read and speak English.

A．Because it welcomes t a big sum of money by tourist
B．Because it thinks that safety measures are followed carefully.
C．Because Russia agrees, too.
D．Because the spaceship is available.

第10题
The reason these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lightning we see flashing down to the earth from a cloud is actually flashing up to a cloud from the earth？ Our eyes trick us into thinking we see a downward motion when it’s actually the other way around. But then, if we believed only what we think we see, we’d still insist that the sun rises in the morning and sets at night.
Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two cloud or between earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on earth every second.
Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashing reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval between the flash and the crash to learn how close they were to the actual spark.
第36题：According to the author, in the area of the Central Valley, ________.
A) rains usually come without thunder and lightning
B) it is usually dry in April
C) children pay no attention to natural phenomena
D) parents are not interested in thunder and lightning
