We often find that weekends and holidays feel so short while classes and work feel so long. In reality, though, we know that this is not true. But we still wonder where that strange feeling comes from.
In fact, this is one of the ways that we're tricked by time, according to the website All That Is Interesting. The website lists several wrong impressions we often have about time. Let's have a look.
First of all, emotions affect our time-keeping abilities: Negative emotions, especially anxiety and boredom, make time seem longer because they make us concentrate more on the passage of time. However, when we are enjoying ourselves, we pay more attention to what we are doing and are likely to lose track of(失去对…的意识) time.
Here is another example. In 2007, a group of scientists carried out a test. In the test, people fell 50 meters into a safety net and were then asked about their experience. Although the experience took shorter than 3 seconds, the people thought it was much longer than it actually was.
This is because of the way our bodies reply to danger, according to the scientists. Our bodies produce a chemical called adrenaline(肾上腺素) when we are faced with danger. It allows us to concentrate better so that we can stay alive. As a result, we are able to remember far more details over a short period of time, which makes it seem like time is going more slowly.
Another occasion when we make mistakes about time is when we take afternoon naps(午觉). Have you ever had trouble telling what time it is after a long nap? That's because the best amount of time for a nap is 20 minutes. After 20 minutes, you enter a new stage of sleep called slow-wave sleep. If you wake up mid-way in this stage, it will take a while before you can correctly perceive(感知) time again.
Yes, time can be mysterious and there is no way to control it So, perhaps the best thing to do is to make good use of every minute. How many examples of being tricked by time are mentioned in the article?
| A．Two | B．Three | C．Four | D．Five |
When people feel that an experience is longer than it really is, _________.
| A．a chemical called adrenaline is playing a role |
| B．they are concentrating on what they are doing |
| C．they are responding faster to the changes around them |
| D．they could be facing danger or feeling bored |
According to the passage, in which situation do we make mistakes about time?
| A．We have a math test when we fall down from a high place. |
| B．We have trouble telling what time it is after a 20 minutes’ nap. |
| C．We have many problems left in the test paper, but the time is up. |
| D．We go to school on the school bus as usual on weekdays. |
What is the article mainly about?
| A．How emotions affect time keeping abilities. |
| B．Tests which scientists carried out about time. |
| C．The best amount of time for an afternoon nap. |
| D．Mistakes that people make in their understandings of time. |
Leadership is the most significant word in todays competitive business environment because it directs the manager of a business to focus inward on their personal abilities and style．Experts on leadership will quickly point out that“how things get done”influences the success of the outcomes and indicates a right way and a wrong way to do things．When a noted leader on the art of management，Peter Drucker,coined the phrase“Management is doing things right；leadership is doing the right things，”he was seeking to clarify the distinctions he associates with the terms．
When Stephen Covey,founder and director of the Leadership Institute，explored leadership styles in the past decade，he focused on the habits of a great number of higllly effective individuals．His Seven Habits of Highly Effective People became a popular bestseller very quickly. His ideas forced a reexamination of the early leadership example，which centered on the feature that was found in the character ethic(道德)and the personality ethic．The former ethic suggested success was founded on modesty,loyalty,courage，patience，and so on. The personality ethic suggested it was one’s attitude，not behavior,that inspired success, and this ethic was founded on a belief of positive mental attitude．In contrast to each of these ideas，Covey advocates that leaders need to understand universal principles of effectiveness，and he highlights how vital it is for leaders to first personally manage themselves if they are to enjoy any hope of outstanding success in their work environments；To achieve a desired vision for your business，it is essential that you have a personal vision of where you are headed and what you value．Business leadership means that managers need to“put first things first,” which implies that before leading others，you need to be clear on your own values，abilities，and strengths and be seen as trustworthy．What does Peter Drucker’s phrase infer?
| A．Leaders should be good at making right decisions． |
| B．Leaders should be good at doing things right． |

Global warming happens when greenhouse gases trap heat and light from the sun in the earths atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out. As a result，the temperature rises.
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it，the earth would be freezing，or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it，so people，plants，and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animals．and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat,and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually,people，plants，and animals would all die of hunger．
People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now,more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming,kids call do just as much. By the example given in Paragraph l, the author wants to__________.
| A．explain how global warming happens. |
| B．show his feeling in a car in hot summer. |
| C．tell us cars are causes of greenhouse gases. |
| D．say that I there are greenhouse gases in every car. |
The underlined wordit in Paragraph 2 refers to__________.
| A．light | B．greenhouse effect |
| C．temperature | D．heat |
What is the effect of atmosphere?
| A．It only traps the heat of the sun. |
| B．It does great harm to humans. |
| C．It makes the earth neither too hot nor too cold. |
| D．It prevents all the light from the sun shining on the earth. |
What is the main idea of the third paragraph?
| A．lf there is greenhouse effect,all the plants will die |
| B．Human beings are likely to disappear from the earth |
| C．Crops can ′t take in the heat lf there is greenhouse effect |
| D．Although greenhouse effect is necessary,too much of it will cause us to die. |
What will the author most probably discuss in the paragraph that follows?
| A．What kids can do to help stop global warming. |
| B．Who should be responsible for the environmental problems. |
| C．What global warming is doing to the environment. |
| D．Why cars and buses pollute the air a lot. |
Researchers are finding new ways to save snakebite victims.Experts discussed the latest findings during a recent conference.
Scientists in Australia have shown that a chemical called nitric oxide could increase the chances of surviving a poisonous snakebite.The scientists injected rats with a deadly amount of snake venom.Then they rubbed an ointment(软膏)containing nitric oxide on the skin around the injection site.The study found that the rats lived about one-third longer than if nitric oxide had not been used.But the treatment had to be started very quickly.
Dirk van Helden led the research.He says the nitric oxide ointment also showed promise in humans.The study appeared earlier this year in the journal Nature Medicine.Scientists say the findings could help save many lives.A recent study found that poisonous snakes cause as many as ninety-four thousand deaths worldwide each year.But Ulrich Kuch of the Biodiversity and Climate Research Center in Frankfurt,Germany,says that number appears to be low.
Mr Kuch says many deaths could be prohibited if snakebite victims are treated correctly,but they often go to traditional healers or do not seek any help at all.He said,“Sometimes it’s because there is no treatment available—no antivenom(抗蛇毒血清),which is the specific(特殊的)drug to treat snakebites—or health care staff do not know how to treat snakebites,and sometimes its because transportation to get to a health facility is not available or too expensive.
Here is no single antivenom that can be used to treat all snakebites.The antivenom must be specific to the kind of snake that bit the person.In some countries the treatment is costly,while in others there is no such treatment.What is this passage mainly about?( )
| A．Snakebite deaths around the world. |
| B．Progress in fighting snakebite deaths. |
| C．Snakebite treatment around the world. |
| D．The chances of surviving a poisonous snakebite. |
After being rubbed an ointment containing nitric oxide,the rats .
| A．suffered no pain |
| B．died immediately |
| C．lived a little longer |
| D．started feeling uncomfortable |
What does Paragraph 3 suggest?( )
| A．The number of deaths caused by snakebites is becoming lower each year. |
| B．The nitric oxide ointment has saved thousands of people’s lives. |
| C．It is very important to find an effective way to treat snakebites. |
| D．The number of deaths caused by snakebites worldwide is low. |
What does the underlined word “prohibited” in Paragraph 4 mean?( )
| A．caused. | B．considered. |
| C．examined. | D．prevented. |
What is implied in the last paragraph?( )
| A．Antivenom can be made very easily. |
| B．It’s very important to use the correct antivenom to treat snakebite victims. |
| C．Antivenom is extremely expensive all over the world. |
| D．A person bitten by a snake will survive as long as there is antivenom. |
Two Chinese living in South Africa were killed in a robbery (抢劫) on February 5, bringing the total number of Chinese killed in the country to four in less than a month.
Chen Jianqing, 35, from Southeast China's Fujian Province, who ran a shop with her husband in a small town 45 kilometers away from South African capital Johannesburg, was shot dead.
"One of her business partners died later in the hospital," the Chinese consulate (领事馆) officials in Johannesburg said yesterday. "Local police are trying to find more information about the case. And we have told the victims' (遇难者的) relatives and are helping them come to Johannesburg," Consul Wu Gang told China Daily. Chen's husband was injured during the robbery but did not suffer seriously, said Wu.
The robbery happened at about 5:45 pm local time and the armed robbers ran away after taking more than 50,000 South African rand (US $8,200) and some jewelry, Xinhua News Agency reported.
The killing happened just three days after Chen Jingmin, a 23-year-old man from Qingdao, Shandong Province, was shot dead north outside Johannesburg by armed robbers. On January 10, a Hong Kong businessman was attacked and robbed at his home in Johannesburg and died the next day in the hospital. All these happened just in less than a month.
According to records, there were more than 40 robberies attacking Chinese in South Africa last year, in which eight were killed. More than 100,000 Chinese are doing various kinds of businesses in South Africa, according to a Chinese official in the country. An increasing number of them are becoming targets (目标) of robbers after buying big houses or luxury cars, the official said.The passage is probably ______.

America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect American society in many ways: education, medicine, and business. Quietly, the aging of America has made us a very different society—one in which people have quite a different idea of what kind of behavior is suitable at various ages.
A person’s age no longer tells you anything about his/her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time. Public ideas are changing.
Many people say, “I am much younger than my mother or my father was at my age.” No one says “Act your age.” any more. We’ve stopped looking with surprise at older people who act in youthful ways.It can be learned from the text that the aging of the population in America _______.
| A．has made people feel younger. |
| B．has changed people’s social position. |
| C．has changed people’s understanding of age. |
| D．has slowed down the country’s social development. |
The underlined word “one” refers to _______.
| A．a society | B．America |
| C．a place | D．population |
“Act your age.” Means people should _______.
| A．be active when they are old. |
| B．do the right thing at the right age. |
| C．show respect to their parents young or old. |
| D．take more physical exercises suitable to their age. |
