Do dogs understand us?
Be careful what you say around your dog. It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also
appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee.
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
The correct object was chosen in seven out of ten tests, suggesting that the dog had worked
out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.
Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its m
ental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return! From paragraph 2 we know that __ .
| A．animals are as clever as human beings |
| B．chimpanzees have very good word-learning skills |
| C．dogs are smarter than parrots and chimpanzees |
| D．dogs have similar learning abilities as 3-year-old children |
Both experiments show that .
| A．Rico is smart enough to get all commands right |
| B．Rico can recognize different things including toys |
| C．Rico has developed the ability of learning mathematics |
| D．Rico won't forget the names of objects once recognizing them |
Which of the following statements is true?
| A．Rico has a better memory partly because of its proper early training. |
| B．The purpose of the experiments is to show the border collie's mental abilities. |
| C．The border collie is world-famous for recognizing objects. |
| D．Rico is born to understand its owner's commands. |
What does the writer want to tell us?
| A．To train your dog. | B．To talk to your dog. |
| C．To be careful with your dog. | D．To be friendly to your dog. |
A child survivor of the Indian Ocean tsunami and a girl from the United States who offered help met for the first time after the disaster.
The 2004 Indian Ocean tsunami destroyed Nada Luthfiyyah’s small town in Aceh. Her parents and two brothers were among the 160,000 people who died in the disaster. Maggie Hamilton’s classmates in the state of Michigan decided to make and sell bracelets (手镯) to raise money for the victims. Maggie, who was 9 years old at the time, wrote a letter to survivors to offer help. Nada was selected from her class to respond with a letter of thanks.
Three and a half years later, the two girls met for the first time. Their meeting was arranged by the Indonesian government, and was used as a symbol of the two countries’aid relationship. Their letters were quoted by diplomats (外交官)of both countries.
Maggie, visiting the town under reconstruction, said she did not expect that her letter would draw so much attention, but, she said, the experience helped to make her more active in volunteering work. "I’ve been volunteering at a nursing home in Ohio. I just want to help people whenever I can," Maggie said.
Juanda, the spokesman for Indonesia’s tsunami reconstruction agency, says the meeting of the two girls serves as a symbol of their informal relationship. It will represent the international community’s role in Aceh’s future. "I think what we can learn from this experience is that Nada from Aceh and Maggie from the U.S. are able to share their experiences, friendship, knowledge and support," Juanda says.
Maggie says she wants to learn Indonesian and hopes to have Nada visit her home in Michigan sometime, perhaps next year.

During his college years, Rogers spent his summer holidays at an Idaho logging camp (伐木场). When Roy, the manager, had to leave for a few days, he put Rogers in charge. "What if the workers refuse to follow my orders?" Rogers asked. He thought of Tony, a worker who was always giving the other men a hard time. "Fire them," Roy said. Then, as if reading Rogers’ mind, he added, "I suppose you want to fire Tony if you get the chance. I’d feel bad about that. Tony is the most reliable worker I’ve ever had. I know he complains a lot, but he comes first and leaves last. There has not been an accident on the hill where he works for eight years." Rogers took over the manager’s job the next day. He went to Tony and spoke to him, "Tony, did you know that I’m in charge today?" Tony didn’t show any respect or interest. "I was going to fire you because you once gave me a hard time, but I want you to know I’m not," he told Tony, adding what Roy had said. When Rogers finished, tears streamed down Tony’s face. That day Tony worked harder than ever before —and he smiled for the first time! Rogers went back to school after that summer. Twelve years later he met Tony again. He was in charge of one of the largest logging companies in the West. Rogers asked him how he managed to become so successful.

The United States government wants to know what the public thinks about its findings on the safety of cloned animals．
The Food and Drug Administration says meat and milk from clones of adult animals are safe to eat．They called them “as safe to eat as the food we eat every day”．
And when those clones reproduce sexually(有性繁殖)，the agency says，their offspring(后代) are safe to eat as well．
The United States this year could become the first country to allow the sale of foods from cloned animals．
First，however，the public will have ninety days to comment on three proposed
documents．On December 28th the F．D．A．released a long report，called a draft risk assessment，along with two policy documents．
The agency says it must receive comments by April second．The F．D．A． seemed ready to act several years ago，but an advisory committee called for more research．
For now，the government will continue to ask producers to honor a request that
they not sell foods from cloned animals．
Clones are still rare．They cost a lot and are difficult to produce．
The F．D．A．says most food from cloning is expected to come not from clones themselves，but from their sexually reproduced offspring．It says clones are expected to be used mostly as breeding animals to spread good qualities．
Public opinion studies show most Americans do not like the idea of food from cloned animals．But this research also shows the public knows little about cloning．
Cloning differs from genetic engineering．A cell taken from a so-called donor animal is grown into an embryo(胚胎)in the laboratory．Next，the embryo is placed into the uterus(子宫)of a female animal．If the process is successful，the pregnancy reaches full term and a genetic copy of the donor animal is born．

China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate (房地产) market, the International Finance News reported.
Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.
The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?
At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate (控制) the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.
1．Which of the following does NOT support the idea that the average housing price in China is even higher than in the United States?
A．Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities.
B．American people’s average income is several dozen times higher than that of Chinese people.
C．The houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses.
D．There are more people who need houses in China than in the United States.
2．What is the main idea of this passage?
A．The Chinese government should do something to control the housing price.
B．There are some bubbles in Chinese real estate market.
C．The average housing price in China is even higher than in the United States.
D．The Chinese government issued a set of policies that aimed to benefit the public.
3．How many measures are mentioned in the last paragraph in order to reduce the high housing prices?
