Four teams of mountaineers set out on a race to conquer (征服) an unclimbed mountain peak in the Himalayas. The Canadian team chose a long, but safe route, while the British, Chinese and Russian teams chose a faster but steep and dangerous route up the mountain.

When night fell, the teams made camp on the mountainside. But the next morning, the sun rapidly rose air temperature and the strong wind caused a heavy snowfall, which led to a terrible avalanche. The disaster struck and some members of the British, Chinese and Russian teams were swept away and killed. But the Canadians didn’t know what had happened.

It was an hour after the disaster and there was no hope of finding any survivors. The leaders of the British, Chinese and Russian teams, met to discuss how to successfully keep all the survivors alive.

【题目】The Mystery of Dark Matter

If you look at the night sky, you'll often see stars moving very quickly. In fact, they move much more quickly than they should according to their size and the laws of physics. Scientists do not completely understand why the speed of these stars is so high. But many believe the reason is that much of the universe is made up of something called "dark matter". Groups of stars called galaxies, such as the Milky Way, might even consist of ninety per cent dark matter.

How much something weighs depends on where it is. The same object weighs only half as much on Mars as it does on Earth and almost three times as much on Jupiter. So scientists prefer to talk about the mass of something rather than how much it weighs, because mass does not change. They can work out the mass of galaxies by measuring the distance between them and the speed they move. Recently, Dr. Jorge Penarrubia and a team from Edinburgh University discovered something interesting. The mass of the Milky Way is only half as much as the mass of another nearby galaxy, Andromeda. This seems strange, but dark matter may explain why.

Finding out more about dark matter could help us understand how the universe began, but this is not easy. Lots of scientists with different types of expert knowledge are working on the problem. The Edinburgh team is working with many other universities like the University of British Columbia.

We can't see dark matter, it's very difficult to measure and we can't find out its mass. Unlike stars, dark matter doesn't produce or reflect light. But we can make a good guess that it is there because of the way things move and the way light bends. Experts now think dark mater may be very different from the mater which we find on Earth. There may also be five times as much dark matter in the universe as ordinary matter.

The Swiss scientist Fritz Zwicky first gave dark matter its name in the nineteen-thirties. Researchers have been looking for it ever since. Today, technology such as the Large Hadron Collider is collecting more and more information but this technology cannot tell us everything. New ways of finding dark matter will be needed. Investigating dark matter may even mean we will need to start asking questions about the way we look at the universe, including the ideas of Albert Einstein.

1In what way do scientists find out the mass of galaxies

A.Depending on where they are.

B.Depending on how much they weigh.

C.According to the way they move and the laws of physics.

D.By calculating how far between them and how fast they move.

2Which of the following statements about dark matter is NOT TRUE

A.It can't be seen.

B.It doesn't reflect light.

C.It is not unlike ordinary matter.

D.It affects the movement of things.

3What may get researchers looking for dark matter

A.To change the way light bends.

B.To prove the ideas of Albert Einstein.

C.To collect more and more information.

D.To help understand the origin of the universe.

4How is the article organized

(P: Paragraph)

A.B.

C.D.

5Which heading best matches Paragraph 5?

A.It's there but we can't see it.

B.Sharing ideas leads to success.

C.We may need to change the way we think.

D.What your eyes can see can't be fully explained,

【题目】Animals in Antarctica

There are no land animals that actually live in AntarcticaHoweverthe surrounding oceans are rich in living creaturesIt’s just too cold to support very many life formsNow let’s meet some of the Antarctica’s animals.

Weddell Seal

They are the southernmost pinniped(鳍足类的)in the world. Males are generally smaller than females. Interestinglya newborn pup has a coat of long hairwhich they will shed(脱落) within the first month as the protective layer of their body is developed.

Blue Whale

Named for its bluegray colorthis huge animal may grow to be roughly 100 feet long and weigh more than 120 tonsA blue whale eats about 4 tons of krill(磷虾)per day during the feeding seasonThis means that about 40 million krill are eaten every day for six months by a blue whaleThe tongue of the blue whale can be as big as a VolkswagenThe blue whale is the loudest animal on earth!

Rockhopper Penguins

One of the more beautiful penguinsthe Rockhopper shake their heads and cause their yellow eyebrows to fly into a “halo”in order to attract a mate!

Wandering Albatross

This species of albatross wanders the oceans for months at a time searching for food. It sleeps on the ocean surface at night and drinks sea water.The Wandering Albatross is the largest bird in the world in terms of wing span—11 feet!

Ross Seal

Ross Seals are very rarely seen because they live deep within the packice. It is believed that Ross Seals feed mainly on squidfish and krill. They were named after the British polar explorer Sir James Rosswho first discovered them in 1840.

Emperor Penguin

Emperor Penguins are the biggest of the 17 penguin species. They are flightless birds. They are the only living species to reproduce during the harsh Antarctic winter. Without a nestthe father Emperor Penguin keeps the egg warm by holding it on his feet for 23 months until springduring which the father doesn’t eat anything and he just eats a little snow for moisture.
