You may have seen a lot of frogs, but if you haven't, you must have heard about frogs. However, have you heard about a frog that can kill a person?
These small brightly colored amphibians (两栖动物) live in the tropical rain forests of Central and South America. They are best known for their ability to kill persons even though they are no more than 2 inches long. If we touch their poisonous skin without proper protection (such as gloves), we may die! For animals of this size that can be so deadly, they are certainly one of the world's most poisonous animals! Who are they? They are poison arrow frogs or, simply, poison frogs.
Poison frogs acquired their name from the Indians. The Indians catch and kill many of these frogs before hanging them upside down over a campfire. As the frogs get hot, the poison drips out of their skin. The Indians collect the poisonous liquid in a bottle and dip(蘸) the tips of their arrows into the bottle. Once the tips are dried, they are ready to be used for their arrows for hunting.
There are about 170 different types of poison arrow frogs in the world. Though most species have bright markings, either in stripes or patches, on their black bodies, some just wear noticeable single-colored coats. Their shocking skin colors-usually in yellow, red, green, blue or orange-serve as a warning sign to other animals. The sign simply says,” Stay away or pay with your life!” They certainly do not bluff.
【小题1】We can infer that the Indians may kill poison frogs in order to______.
| A．treat diseases | B．avoid being bitten |
| C．hunt animals | D．eat their meat |
| A．Poison frogs don't want to kill others. |

In some urban centers, workaholism is so common that people do not consider it unusual．They accept the lifestyle as normal．Government workers in Washington D．C．, for example, frequently work sixty to seventy hours a week．They do this because they have to; they do it because they want to．
Workaholism can be a serious problem．Because true workaholics would rather work than do anything else, they probably don't know
how to relax; that is, they might not enjoy movies, sports, or other
types of entertainment．Most of all, they hate to sit and do nothing．The lives of workaholics are usually stressful, and this tension and worry can cause health problems such as heart attacks or stomach ulcers．In addition, typical workaholics don't pay much attention to their
families．They spend little time with their children, and their marriages may end in divorce．
Is workaholism always dangerous? Perhaps not．There are, certainly, people who work well under stress．Some studies show that many workaholics have great energy and interest in life．Their work is so pleasurable that they are actually very happy．For most workaholics, work and entertainment are the same thing．Their jobs provide them with a challenge; this keeps them busy and creative．
Why do workaholics enjoy their jobs so much? There are several advantages to work．It provides people with paychecks, and this is important．But it offers more than financial security It provides people with self-confidence; they have a feeling of satisfaction when they have produced a challenging piece of work and are able to say," I made that．" Psychologists claim that work gives people an identity; by working, they get a sense of self and individualism．In addition, most jobs provide people with a socially acceptable way to meet others．
【小题1】A workaholic is a person who____．
| A．tends to work long hours |
| B．behaves in a strange way |

Someday a stranger will read your e-mail without your permission or scan the Website you’ve visited，Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.
In fact, it’s likely some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girl friend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen --- the 21st century equivalent of being caught naked.
Psychologists tell us boundaries are healthy, that it's important to reveal yourself to friends, family and lovers in stages, at appropriate times.But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.
The key question is: Does that matter?
For many Americans, the answer apparently is “no.”
When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me.”
But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths (收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acauisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon (优惠卷).
But privacy does matter - at least sometimes. It’s like health: When you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it.
【小题1】What does the author mean by saying “the 21st century equivalent of being caught naked” (Lines 3-4, Para. 2)?
| A．People's personal information is easily accessed without their knowledge. |
| B．In the 21st century people try every means to look into others’ secrets. |
| C．People tend to be more frank with each other in the information age. |
| D．Criminals are easily caught on the spot with advanced technology. |
| A．Friends should open their hearts to each other. |
| B．Friends should always be faithful to each other. |
| C．There should be a distance even between friends. |
| D．There should be fewer disputes between friends. |
| A．Modern society has finally evolved into an open society. |
| B．People leave traces around when using modern technology. |
| C．There are always people who are curious about others’ affairs. |
| D．Many search engines profit by revealing people’s identities. |
| A．They change behaviors that might disclose their identity. |
| B．They use various loyalty cards for business transactions. |
| C．They rely most and more on electronic devices. |
| D．They talk a lot but hardly do anything about it. |

A new generation addiction is quickly spreading all over the world. Weboholism（网瘾）, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.
Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(写日志) on computers and spend long hours at different websites.

A newly-published study has shown that loneliness can spread from one person to another, like a disease. Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.
Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.
University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.
Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.
The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.
The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.
Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.
The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.
【小题1】What is TRUE about the Framingham Study?
| A．It was only conducted in 1948. |
| B．It involves more than 12,000 participants. |
| C．It was led by John Cacioppo. |
| D．It showed that any behavior could spread. |

| B．No spreading effect was found on husbands and wives. |
| C．Women are more likely to be affected than men. |
| D．Brothers are more easily affected than neighbors. |
| A．Actions should be taken to help lonely people. |

Mother’s Day is a holiday for mothers. It is celebrated(庆祝)in the United States, England, India and some other countries. In a short time, it becomes widely celebrated. Mother’s day falls on the second Sunday in May. On that day, many people send gifts(礼物)of love to their mothers.
Those whose mothers are still living often wear a pink or red rose or carnation(康乃馨)， while those whose mothers are dead wear a white one.
The idea of a day for mothers was first given by Miss Anna Jarvis of Philadelphia. As a result of her hard work, the celebration of the first American Mother’s Day was held in Philadelphia(费城） on May 10, 1908. Soon the holiday became popular all over the country and around the world.
In China, people do the same on the day for mothers. And, in some cities, people sometimes ask a song to be broadcast(广播) for his or her mother only. This might cost a little money for some of them, but, as it is said, “Love is invaluable.”
On May 8, 1999, just the day before the Mother’s Day that year, a Chinese mother was killed in criminal bombing(罪恶轰炸). Her name is Shao Yanhuan, a heroic mother. All the Chinese will remember her forever.

Dr. Wiseman started the “laugh lab” project in September 2001. It is the largest study of humor. Participants are invited to log on the laugh lab website, give a few personal details, tell their favorite jokes and judge the jokes told by other people.
Their project will last for a year, and the organizers hope to finally discover the world’s funniest joke. But there is also a serious purpose. The researchers want to know what people from different nations and cultures find funny. And they want to find out the differences between male’s and female’s sense of humor. The idea is that if we want to understand each other, we have to find out what makes us laugh.
This is a subject that has long interested psychologists (心理学家) and philosophers (哲学家). Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves.
By December 2001 over 10,000 jokes had been submitted (公认的). This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humor, for example.
“Our findings show the major differences in the ways in which males and females use humor,” said Dr Wiseman. “Males use humor to appear superior (高傲的，有优越感的) to others, while women are more skilled in languages and prefer word play.”
Researchers also found that there really is such a thing as a national sense of humor. The British enjoy what is usually called “toilet humor”. But the French like their jokes short and sharp, “You’re a high priced lawyer. Will you answer two questions for $ 500?” “Yes. What’s the second question?”
The Germans are famous for not having a sense of humor. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that proves the point. Is this joke funny? I don’t know, but let’s say yes, just to be safe.
Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief (安慰). Computers already seem like they can do everything. But at least they should leave the funny things to us.
【小题1】The scientist started the “laugh lab” project ________.
| A．to find the funniest joke in European countries |
| B．to know what funny people are from different nations and cultures |
| C．to find out the differences between the male’s and female’s sense of humor |
| D．to get more personal details about participants |
| A．to show that the French people have a better sense of humor |
| B．to prove the British people have a sense of “toilet humor” |
| C．to show people from different nations have different senses of humor |
| D．to prove that the Germans have no sense of humor |
| A．The jokes by computer are less funny than those by humans. |
| B．The Germans cannot find the submitted jokes amusing. |
| C．Males are better at word play compared with women. |
| D．Females like to use humor to show that they are superior. |
