Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.
Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking（减少） ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.
In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast（绝食） during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.What is Arctic ice doing earlier each year?

Celebrations spread across China when Shanghai, the Oriental Pearl, was given the right to host the 2010 World Expo on December 3. Shanghai won the honor after beating rivals from Russia, Mexico, Poland and South Korea.
“I’m very proud of being Chinese,” said Wang Kaibo, a Senior 2 student of the Middle School Affiliated (附属的) to Beijing Medical University. “The winning of the expo is a victory, not only for Shanghai resi
dents, but for the people of the whole Chinese nation.”
Bidding for the expo shows that China is more confident of playing a more important role on the international stage. It’s competing for large events and the next one could be the World Cup, Wang said.
The World Expo 2010 and the 2008 Beijing Olympics will become the twin shining stars of China’s development over the next 10 years, said experts. The World Expo is known as “Olympics of the economic, cultural, scientific and technological fields.” It is usually held every five years and lasts for six months. The Olympics, World Cup and World Expo are considered three top international events in the world.
China is the first developing country to win the expo bid in the event’s about 159-year history. Not only will it attract more foreign investment to China, but experts say that the half-year-long exhibition will bring at least 70 million visitors to Shanghai.
The expo was first held in London in 1851. It has a history of global influence. The Eiffel Tower, built during the Paris World Expo in 1889, became the symbol of the French capital.Many historic inventions, such as the telephone and airplane, all made their first appearance at a World Expo.

I’m a pig, and my son is a rabbit. I have snakes for daughters, and my wife, believe it or not, is a dragon! Do I live in a zoo? No, of course not! I am talking about Chinese zodiac signs. Depending on the year of your birth, each person has an animal for a sign. That’s why I am a pig and my wife is a dragon. If you, like me, were born in the year of the pig, then you are brave, thoughtful and loyal. The year of the pig is filled with good fortune.
Now let’s take a closer look at this interesting animal.
Pigs were first raised by man about 9,000 years ago, and are still a very common farm animal in many parts of the world. We don’t just use pigs for their meat — almost every part of the animal is used. The hair is used for artists’ brushes. The fat is used to make floor wax, rubber and plastics.
Pigs have also been important in the world of entertainment. In 1995 the film ‘Babe’ starred a loveable talking pig as its main character. The film won an Oscar and was nominated for 6 more. In England you can even go to watch pig racing. A farmer, Rob Shepherd, has been raising money for charity by holding pig races on his farm. The events have been very successful. People don’t just want to eat pigs, it seems!
Pigs also play an important r
ole in the English language. For example, if someone says that he will travel to the sun one day, you can say “pigs might fly!” to him. Hungry? Well then, you can “pig out” and eat lots of food. And what if someone rescues you? Well, you can say that they “saved your bacon”.

A major earthquake rocked Haiti at 4:53 pm local time on Jan.12, 2010, killing possibly thousands of people but no official figure has been released so far.
The quake, which struck about 15km (10 miles) south-west of the capital, Port-au-Prince, was quickly followed by two strong aftershocks. In the space of a minute, numerous buildings fell down. A five-story U.N. building was also brought down by the 7.3 magnitude quake, the most powerful to hit Haiti in more than 200 years according to the U.S. Geological Survey.
As night fell, the whole city is in total darkness. You can see thousands of people sitting in the streets with nowhere to go. There are people running, crying, screaming. Describing the earthquake as a "catastrophe", Haiti’s president said the cost of the damage could run into billions.
Haiti became the first independent Caribbean state in the early 19th century. Haiti's location, history and attracting climate once made it a tourist hot place. However, decades of poverty, environmental pollution and violence have left it as the poorest nation in the Americans. It has suffered a lot, including four hurricanes and storms in 2008 that killed hundreds.

When did you last see a polar bear? On a trip to a zoo, perhaps? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3℃, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group, this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.
Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits (or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system(循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.
The main benefits(or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says. "When I go into the water, I pour my troubles into the ocean and let them float away."

Societies all over the world name places in similar ways. Quite often there is no official naming ceremony but places tend to be called names as points of reference by people. Then an organized body steps in and gives the place a name. Frequently it happens that a place has two names: One is named by the people and the other by the government. As in many areas, old habits died hard, and the place continues to be called by its unofficial name long after the meaning is lost.
Many roads and places in Singapore are named in order that the pioneers will be remembered by future generations. Thus we have names such as Stamford Road and Raffles Place. This is in keeping with traditions in many countries —in both the West and the East.
Another way of naming places is naming them after other places. Perhaps they were named to promote friendships between the two places or it could be that the people who used to live there were originally from the places that the roads were named after. The mystery is clearer when we see some of the roads named in former British bases. If you step into Selector Airbase you will see Piccadilly Circus—obviously named by some homesick Royal Air Force personnel.
Some places were named after the activities that used to go on at those places. Bras Basah Road is an interesting example, “Base Basah” means “wet rice” in Malay. Now why would anyone want to name a road “Wet Rice Road”? The reason is simple. During the pioneering days, wet rice was laid out to dry along this road.
A few roads in Singapore are named by their shapes. There is “Circular Road” for one. Other roads may have part of their names to describe their shapes, like “Paya Lebar Crescent”. This road is called a crescent（月牙） because it begins on the main road, makes a crescent and comes back to join the main road again.
46. We learn from Paragraph 1 that _____.
A. the government is usually the first to name a place
B. many places tend to have more than one name
C. a ceremony will be held when a place is named
D. people prefer the place names given by the government
47. What does the underlined phrase “die hard” in Paragraph 1 probably mean?
A. Change suddenly. B. Change significantly（greatly）.
C. Disappear mysteriously. D. Disappear very slowly.
48. Which of the following places is named after a person?
A. Raffles Place. B. Selector Airbase. C. Piccadilly Circus. D. Paya Lebar Crescent.
49. Bras Basah Road is named _______.
A. after a person B. after a place C. after an activity D. by its shape
50. What can be inferred from the passage?
A. Some place names in Singapore are the same as in Britain.
B. Some places in Singapore are named for military purposes.
C. The way Singaporeans name their places is unique.
D. Young Singaporeans have forgotten the pioneers.
