Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”. Whistles and chirps are like the sounds that many birds make. Now scientists have translated some of their squirrel-speak.
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls. The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍）their responses. Some squirrels lifted their heads up and became alert(警惕的）. Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger. ' " Hare told. Discovery News.
Hare and some other researchers believe such sounds are part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behavior, thus increasing the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too. According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害兽）. Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.The text mainly talks about _______ .

Through history, children have played with toys and they help to prepare children for adult life. But the toys are changing all the time. As science and technology have changed the way adults live, the toys children play with have changed as well. Developments in science and technology have had a big effect on the toys that children play with. Today trains and mobile phones are popular toys for young children, but there were no toys of this kind before real trains and mobile phones were invented. The materials that toys are made of have also changed. Today lots of toys are made of plastic. Plastic is a modern, man-made material that did not exist (存在) in the past. On the other hand, some other toys that you have might not be all that different from the ones children played with 1,000 years ago. Scientists have found some bone dice (骰子)in Aberdeen. In medieval (中世纪的)times dice were used for playing games as much as they are today.
A recent survey found that half of all the children aged from 4 to 6 have played video games, a quarter of them regularly. The increasing use of electronic toys troubles Dr Singer, a professor at Yale. “One thing we know is that kids in early years need to be in touch with the real world,” he said, “No matter how brilliant they are, they’re not going to learn to walk, to move or to talk to others unless their hands or feet have a direct role in such activities.”
Some toy experts argue that the best toys are the ones that increase a child’s creativity and imagination. Traditional toys can be used for different kinds of purposes and be used in group settings, individually(单独地), and one-to-one. They are also used differently depending on the child’s age and skill level. And these toys made of natural materials are valuable for children because they teach children what the world is made of.In how many ways do toys change according to the first paragraph?
| A．One. | B．Two. | C．Three. | D． Four. |
From the article, we can know that .
| A．only children like to play with toys |
| B．toys have nothing to do with children’s future life |
| C．the development of toys is related to science and technology |
| D．plastic is the best material for making toys |
According to Dr Singer, .
| A．the electronic toys are good for children if they play often enough |
| B．the electronic toys prevent children keeping in touch with the real world |
| C．children should be stopped from being hurt by the danger coming from the outside world |
| D．children should play with electronic toys instead of the traditional ones |
There are a number of special days of the year that are celebrated in different countries. The origins of most of the days are unknown. They were certainly not created by individual people. Other days, however, especially those celebrated in western countries, often owe their origins to a particular person. One of the most popular of these, even though it is fairly recent, is Mother’s Day. Mothers have always been highly regarded in all cultures. The ancient Romans had a festival known as Hilaria, during which children took presents to the temple of the “Mother of the Gods”. The Christian Church adopted this idea and called it Mothering Sunday. However, over the years this custom was gradually forgotten and almost disappeared by the end of the 19th century.
Born in 1864 in Virginia, USA, Anna Jarvis was a school teacher and believed children should show gratitude to their mothers for all their love and care. Encouraged by a friend, she wrote to thousands of important people—politicians, churchmen, doctors, city officials—and asked them to support her idea: a special day of the year for thanking mothers.
In 1910 the Governor of West Virginia introduced Mother’s Day into the state. The date chosen was May 10—the second Sunday in May, which is still observed in America today. This date was chosen because May 10 was the date on which in 1908 Anna Jarvis’s mother had died. In 1914 President Woodrow Wilson made May 10 the official date for Mother’s Day throughout the United States.
Soon there was a Mother’s Day International Association and the custom began to be adopted in many countries of the world.
Anna Jarvis, a sad and disillusioned（失望的） woman, died in 1948. The custom she had worked so hard to establish and which had become almost universal had lost its original purpose. It had been taken over by business. Like Christmas, the giving of presents and the sending of cards had become a multi-million-dollar industry. The story is about .

| A．May is in the American spring |
| B．it was the second Sunday in May in 1910 |
| C．President Wilson liked the date |
| D．this was the date on which Anna Jarvis’s mother died |
Unfortunately, Anna Jarvis was not happy with Mother’s Day when she died because .
| A．her mother was not there to see it |
| B．she had never been a mother herself |
| C．people were too interested in making it a business |
| D．no one gave any presents or cards to their mothers |
Recently, a professor of philosophy in the United States has written a book called MoneyandtheMeaningofLife. He has discovered that how we deal with money in our daytoday life has more meaning than we usually think. One of the exercises he asked his students to do is to keep a record of every penny they spend for a week. From the way they spend their money, they can see what they really value in life.
He says that our relation with others often becomes clearly defined when money enters the picture. You might have wonderful friendship with somebody and you think that you have a very good friend. But you will know him only when you ask him to lend you some money. If he does, it brings something to the relationship that seems stronger than ever before. Or it can suddenly weaken the relationship if he doesn't. This person may say that he has a certain feeling, but if it is not carried out in the money world, there is something less real about it.
Since money is so important to us, we consider those who possess a lot of it to be very important. The author interviewed some millionaires in researching his book.
Question: What is the most surprising thing you have discovered about being rich?
Answer: The most surprising thing is why people give me so much respect. I am nothing. I do not know much. All I am is rich.
People just have an idea of making more and more money, but what is it for? In his book, the professor uncovered an important need in modern society: to bring back the idea that money is an instrument rather than the end. Money plays an important role in the material world, but expecting money to give happiness may be missing the meaning of life.The author seems to believe that asking your friend to lend you some money ________.
| A．is a good way to test your friendship |
| B．will do harm to your friendship |
| C．will strengthen your friendship |
| D．is a good way to break off your friendship |
What can we learn about the millionaire from his answer in the interview?
| A．He does not feel that he is well educated. |
| B．He does not think that he is a very important person. |
| C．He does not think that being rich is worth so much attention. |
| D．He does not consider himself to be very successful. |
What does the American professor of philosophy want to explain in his book?
| A．Money is an end. | B．Money is a means. |
| C．Money is everything. | D．Money is unimportant. |
Which of the following might the author disagree with?
| A．Money is important in modern society. |
| B．The meaning of life does not completely lie in money. |
| C．Wealth will surely bring the owner happiness |
| D．Happiness is not necessarily the result of wealth. |
William Shakespeare is the most famous playwright (剧作家). Although he died in 1616, people still go to see his plays. Among the most popular are Ｒｏｍｅｏ ａｎｄ Ｊｕｌｉｅｔ, Ａ Ｍｉｄｓｕｍｍｅｒ Ｎｉｇｈｔ’ｓ Ｄｒｅａｍ and Ｈａｍｌｅｔ — the story of a prince who struggles to respond to the crimes around him.
Shakespeare, who was born in 1564, was an actor as well as a writer. Most of his ideas for plays were taken from history, people’s conversation, ancient stories, and also from other writers. He wrote not only about kings and queens and princes, but also about friends and ordinary people. He wrote about the cruelty of war and the bravery of heroes, as well as about jealousy, joy, hate, ambition and love. His stories live on. The tragedy Ｒｏｍｅｏ ａｎｄ Ｊｕｌｉｅｔ was reborn as the musical Ｗｅｓｔ Ｓｉｄｅ Ｓｔｏｒｙ and more recently as the movie Ｒｏｍｅｏ ａｎｄ Ｊｕｌｉｅｔ with the wonderful performance of Leonardo DiCaprio and Claire Danes.
He invented a number of great characters: powerful magicians, thrilling witches, smart women and both wise and wicked men. He also invented some great phrases. If you’ve ever said, “Oh, for goodness sake!” you can thank Shakespeare for that. “To be, or not to be: that is the question,” Hamlet says. “Good night, good night. Parting is such sweet sorrow, that I shall say good night till it is morrow,” says Juliet to her Romeo.
Don’t be surprised if you don’t understand everything when reading Shakespeare or watching one of his plays because the meanings of many words have changed over the years. And Shakespeare’s characters speak in poetry, so their speeches can be complicated.

Say sorry to your wife---it may help her live longer, according to scientists.
“Sorry” may be the hardest word, but scientists say it could be one of the healthiest. Researchers have discovered that women who receive an apology for hurtful behavior suffer less stress and possible damage to their heart than those who don’t.
It is said that the heartbeat of a wronged woman returns to normal 20 percent quicker after a well-timed “sorry” than without it. But for men, their heartbeat takes longer to recover, according to the research.
The research was undertaken by American scientists using 29 men and 59 women whose diastolic blood pressure was measured throughout an experiment. Diastolic blood pressure
is a measure of pressure in the blood vessels( 血管 ) between heartbeats---if it is continuously high it can increase the chances of heart attacks.
The men and women were asked to undertake a difficult mathematical task. They were told they had five minutes to complete it but were disturbed after a minute and told rudely to carry out the task more quickly. They were disturbed twice more before five minutes had passed and told to speed up. Finally they were told, “ You’re obviously not good enough.” Two minutes later researchers said sorry to half of the men and women.
The researchers found that, on average, the women’s diastolic blood pressure dropped back to normal 20 percent---quicker if they received an apology from the researchers, while the men’s took 20 percent longer to return to normal. One of the researchers said, “Results indicates that the effects of apology and forgiveness on women are greater.” The term “sorry” is considered as one of the healthiest words because it _________.
| A．is the most powerful |
| B．can cure heart disease |
| C．helps people forget hurtful behavior |
| D．can reduce pressure and damage to the heart |
We can know from Paragraph 3 _________.
| A．women’s hearts beat faster than men’s |
| B．women are quicker at making apologies |
| C．men can forgive others’mistakes more easily than women |
| D．men stay angry for a longer time than women after receiving an apology |
Which of the following is the RIGHT time order for events in the study?
a. Half of them received apologies.
b. They were disturbed a minute later.
c. They were told that they weren’t good enough.
d. They were asked to finish a math task in five minutes.
e. They were disturbed two more times during the study.
| A．d-b-c-e-a | B．d-c-b-a-e | C．d-b-e-c-a | D．d-c-b-e-a |
The research confirmed (证实) that _________.
| A．men are unwilling to apologize to others for their mistakes |
| B．men’s chances of getting heart attacks are higher than women’s |
| C．women can benefit more from receiving apologies than men |
| D．people can also get healthy benefits from giving apologies |
