Can dogs and cats get along well in the same home? People who are thinking about getting a dog as a friend for their cat are worried that they will fight. A recent research has found that if the cat is taken back home before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. In two-thirds of the homes cats and dogs have a good relationship.
However, it wasn’t all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression(侵略，好斗) and fighting were found in 10% of the homes. One reason for this is probably that some of their body languages are just different. For example, when a cat turns its head away it means aggression, while a dog doing the same means submission(顺从).
In homes with cats and dogs living peacefully, researchers found a surprising behavior. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk “Dog”, and dogs can learn how to talk “Cat”.
What’s interesting is that both cats and dogs have appeared to become smarter. They can learn to read each other’s body languages, suggesting that the two may have more in common than was expected. Once familiar with each other’s body language, cats and dogs can play together, and enjoy sleeping together on the sofa.
The importance of this research on cats and dogs may go beyond pets — to people who don’t get along well, including neighbors, colleagues at work, and even countries. If cats and dogs can learn to get along, surely people have a good chance.The underlined word swimmingly in Paragraph 1 is closest in meaning to ________.
| A．early | B．mostly | C．quickly | D．smoothly |
What is found surprising about cats and dogs?
| A．They eat and sleep together. |
| B．They watch each other’s behaviors. |
| C．They learn to speak each other’s language. |
| D．They know something from each other’s voices. |
It is suggested in Paragraph 4 that cats and dogs ________.
| A．have common interests |
| B．are less different than was thought |
| C．have a common body language |
| D．are not so smart as was expected |
What can we human beings learn from cats and dogs?
| A．We should learn to get along well with others |
| B．We should know more about animals. |
| C．We should live in peace with animals. |
| D．We should learn more body languages. |
Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable（易受伤的）to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen（腹部）.According to Ms Davis, brain cancer increase ____.
| A．among children | B．among old people |
| C．in the twenties | D．among pregnant women |
Why do children easily be affected by radiation?
| A．Because they haven’t grown up. |
| B．Because they are too young to protect themselves. |
| C．Because they use cell phones more often than adults. |
| D．Because their skulls are thinner and their brains are easily hurt. |
What can we conclude from the last paragraph?
| A．Pregnant women should keep cell phones away. |
| B．People should use cell phones in the correct way. |
| C．If you are a child, you’d better text than make phone calls. |
| D．When you use a cell phone, use a wired headset or the phone’s speaker. |
What does the passage mainly talk about?
| A．Be careful when using cell phones. |
| B．Don’t hold your cell phone against your ear. |
| C．Rats exposed to radiation have damaged DNA in their brains. |
| D．Low-energy radiation could damage cells that could lead to cancer. |
Wherever she goes, Molly leaves her mark. Without saying a word, she speaks to people with her kind eyes. Even when she walks away, she leaves an impression．Molly's mark is a smile, stamped into the ground by the horseshoe at the bottom of her false leg．
A few years ago, Molly was badly attacked by a dog．The dog bit all four or Molly’s legs and left large cuts in her face. Molly's owner, Kate Harris, took her to an animal hospital．Doctors there were able to save Molly’s life, but soon one of her legs became very infected(感染).
At first, doctors thought Molly would have to be put to sleep．But Molly changed their minds. This pony, doctors noticed, shifted her weight, and rested her good leg from time to time. Doctors knew t hat Molly had amazing intelligence, and that she wanted to live.
Several doctors operated on Molly, and removed her infected leg. A false leg was made for her. The leg was a hollow cast with a pole at the bottom for balance. Doctors gave Molly a special horseshoe at the bottom of the leg. This horseshoe she had had a stamp of a smile face in it!
After the operation, Molly walked around on all four legs, as if nothing had ever happened to her! Now, with every step she takes, she stamps a smile in the dirt．But she leaves her m ark in other ways, too.
Kaye Harris took Molly to the false leg center. There were children there who, like Molly, had artificial arms or legs. They were amazed to see a pony with a false leg. Molly made them smile and gave them hope. Soon, Molly began to visit schools, nursing homes, army bases and hospitals. A book was even written about Molly!Molly is the name of a__________.
| A．dog | B．horse | C．parent | D．child |
Which of the following is true according to the text?
| A．Molly can speak to people in kind words. |
| B．Kay Harris took Molly to a children’s hospital after the attack. |
| C．In the beginning, doctors had planned to end Molly’s life. |
| D．Molly sometimes leaves smiling marks on people’s faces. |
What is unique about Molly?
| A．Molly has a false leg with a horseshoe shaped like a smiling face. |
| B．Molly ran a race and won the first prize. |
| C．Molly often visits places such as schools and parks. |
| D．Molly has become a symbol of hope for people of all ages. |
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 reponses．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 arc 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 behaviour, thus increasingly 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
| A．the study on the language of squirrels |
| B．the comparison between squirrels and chickadees |
| C．the calling for the protection of squirrels |
| D．the ways for squirrels to escape from their enemies |
If a squirrel is in a very dangerous situation, it would probably make ____．
| A．whistles with chucks | B．pure chirps |
| C．whistles without chucks | D．repeated chucks |
The underlined word “tidings” in pardgmph 6 probably means ____．
| A．difficulties | B．poises | C．messages | D．languages |
What can be learned from this text?
| A．Squirrels communicate with cach other as humans do. |
| B．Some squirrels understand the recorded alarm calls. |
| C．Other animals also well understand the language of squirrels． |
| D．Birds such as chickadees don’t have their own language． |
Moral science is taught as a subject in most schools but with little effect. Perhaps part of the problem lies in the fact that morality is not a science, strictly speaking. It is too much of a social phenomenon, and also has too much of the personal and subjective things mixed within. Besides, morality itself changes with generations. So it is impossible to be defined in a textbook.
I remember sitting through forty minutes of moral lessons, which told stories about little children who never told lies and were rewarded for their goodness. It had little effect and left no impression on me, though.
If moral science has to be taught as a subject in schools, it needs a participatory(参与其中的) approach. When you tell a child about morals, you also have to deal with social norms（规范）and cultural differences. You have to explain that morality can be subjective, and be able to co-exist in society. You will probably have to refer to the morals of the present time.
The best way to tell a child how to live is to show him what is valued. If a child likes his friend, you have to make the child think about why. Once the child notices and recognizes goodness in others, he or she is likely to develop it as well.
In fact, children learn most of their morals by watching people around them. They absorb behavior patterns from teachers and older students. They watch to see what is rewarded and who is punished. They learn on the sports field and through social work. Moral science lessons should simply consist of letting them live and interact, and watch you support correct values and reward good behavior. Which is NOT the reason that moral science is taught in schools but with little effect?
| A．Morality doesn’t strictly belong to a science. |
| B．Morality is more like a social phenomenon. |
| C．Morality can’t be written down in textbooks. |
| D．Different generations have different moral ideas. |
The author describes his own experience of having moral lessons in order to _____.
| A．explain telling lies is not moral for little children |
| B．advise people should be rewarded for their goodness |
| C．show he has no opinions about moral science |
| D．prove moral lessons in schools have little effect |
When you tell a child about morals, you should________.
| A．teach him to share personal moral ideas with others |
| B．tell him about social norms and cultural differences |
| C．explain that nobody can influence his moral ideas |
| D．say that the present morals are likely to be changed |
What is the last paragraph mainly about?
| A．The influence of people’s behavior on morals. |
| B．The value of teachers’ setting a good example. |
| C．The best way of teaching children about morals. |
| D．The importance of rewarding good behavior. |
Are you a problem shopper? The answer is “Yes”, if you or someone else thinks that you sometimes get carried away with shopping. In other words, do you or does someone else think you are occupied in extreme shopping? If people have regrets later about their shopping, or have an “out-of-control” feeling about the quantities of what they buy or the amount of credit they use, they may be considered to be problem shoppers.
Extreme shopping can lead to a more serious problem – addictive shopping. Addictive shoppers feel driven by the desire to shop and spend money. They experience great tension which drives them to shop and spend money and they feel a “rush” during the time they are occupied with the shopping activity.
Extreme or addictive shopping may result from long-time unpleasant feelings, of which anxiety, pain and shame are common ones. When we feel bad inside, we often do something to make ourselves feel better. In this case, we often go shopping.
A few people shop to relieve their boredom or emptiness. For some people, the motivation is a desire for status, power, beauty or success. Some love to shop as it makes them feel valued in the eyes of the shop assistants. Others shop simply because it makes them forget, at least temporarily, tension, fear or unhappiness in their life.
Besides, shopping malls are designed to encourage continual shopping. For instance, there are some malls where you can’t see clocks displaying the time because they don’t want you to become too aware of the time you spend there. What’s more, food courts, coffee shops and restrooms are provided, so you don’t have to leave the mall because of your physical needs.
Therefore, once you become aware of how market forces work, you will certainly come to control your shopping behavior. For example, how much time you will spend and what areas you will visit can be decided before you enter the mall. Keep a written account of what items you will buy and how much money you will spend. Make a plan for what you are going to buy before you feel the urge to shop and then stick to it. That is vital for gaining self-control.Which of the following people may not be problem shoppers?
| A．Those who cannot control the amount of credit they use. |
| B．Those who feel sorry for their shopping. |
| C．Those who are occupied in too much shopping. |
| D．Those who just walk around the shopping malls. |
According to the passage, what may not result in addictive shopping?
| A．The desire for status, power, beauty or success. |
| B．The awareness of how market forces work. |
| C．Boredom, emptiness, tension, fear or unhappiness in people’s life. |
| D．Long-time bad feelings of anxiety, pain and shame. |
What does the author suggest to control our shopping behaviour?
| A．Never going to the shopping malls because there are many tricks. |
| B．Applying for a credit card before we go shopping. |
| C．Making a shopping list before we go shopping. |
| D．Making the shopping time as short as possible. |
The author writes this passage to .
| A．inform the shopping malls how to attract more shoppers |
| B．tell a shopping story |
| C．scold the problem shoppers |
| D．provide solutions to the problem shopping. |
