,000 years old. The first English people, the Saxons, were fishermen there, and they gave Greenwich its name "green village". Before came the Roman, you could still walk on the old Roman road in Greenwich Park. But the river was the true road to the outside world for the Romans, and for the English kings and queens who later live at Greenwich in their beautiful palaces.

The name of the earliest palace was Placentia. Its windows were made of glass--the first in England. Herry Va loved placentia. But Henry understood the future of his country, too: he knew that England must be strong at sea. So he started two big shipyards at Greenwich, and for 350 years the ships made there were the best in the world.

In 1649, a war started in England and for eleven years there was no king. When the war ended, Placentia was falling down. So King Charles 1I built a new and bigger palace, which is now the Royal (皇家的) Naval College and is open to the public.

At this time, Charles was worried about losing so many of his ships at sea: Their sailors didn't know how to tell exactly where they were. So in 1675 Charles made John Flamsteed the first Astronomer (天文台) Royal, to try to find the answer. Flamsteed worked in a new Observatory (天文台) on the high ground in Greenwich Park. With a telescope he made himself, Flamsteed could look all around the sky. And he did, night after night, for twenty years. Carrying on Fiamsteed's work a hundred years later, an astronomer called Harrison (1693 - 1776) finally made a clock which told the time at sea; and helped sailors to know where they were. You can see Harrison’s clock, still working, in Greenwich’s museum of the sea. Because of Flamsteed’s work, every country in the world now tells its time by Greenwich time.

Who first lived in the place that is called Greenwich today according to this passage ？ ______.

A．Henry Ⅷ

B．Romans

C．Charles Ⅱ

D．the Saxons

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

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

Here is some information about making international phone calls.

You can now phone almost any country in the world, although in some cases you can only call big cities. When you cannot make direct dialing calls, you can ask the international operator to help you. This is more expensive and takes more time, but it may be helpful if you want to speak to a particular person and no one else, in this case you should ask for a "person-to-person" call. Even more expensive is a reverse charge call where the person who receives the call pays. If the international line is busy, you can reserve(留下) a call, explain the number you want and the operator will call you back when the line is free.

You can save money by calling outside office hours, for example, early in the morning, late at night, and on Sundays. Remember that the time may be different in the country that you are calling. International time is based on GMT (Greenwich Mean Time). London is on GMT and Moscow, for example, is 3 hours ahead. There is one problem: change to DST (Daylight Saving Time) for the summer. In the UK, clocks are put forward one hour in spring and put back in autumn, and so London is actually one hour ahead of GMT in the summer.

What is the most expensive type of call？

A．Direct dial.

B．Through the operator.

C．Reverse charge call.

D．Calling outside office hours.
