When people want to know about the weather, they usually go to there radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure（壓力） produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around, Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable（急躁的）and quarrelsome and will fight over a piece of bread. Other birds chirp（嘰嘰喳喳）and sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also seek safe places before a storm, You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre-storm low pressure makes the are so thin that birds have difficulty flying.
It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm.

Most people around the world are right-handed . This also seems to be true in history . In 1799 , scientists studied works of art made at different times from 1,500 B.C. to the 1950s . Most of the people shown in these works are right-handed , so the scientists guessed that right-handedness has always been common through history . Today , only about 10% to 15% of the world’s population is left-handed .
Why are there more right-handed people than left-handed ones ? Scientists now know that a person’s two hands each have their own jobs . For most people , the left hand is used to find things or hold things . The right hand is used to work with things. This is because of the different work of the two sides of the brain . The right side of the brain , which makes a person’s hands and eyes work together , controls the left person’s hands and eyes work together , controls the left hand . The left-side of the brain , which controls the right hand , is the centre for thinking and doing problems . These findings show that more artists should be left-handed , and studies have found that left-handedness is twice as common among artists as among people in other jobs .
No one really knows what makes a person become right-handed instead of left-handed . Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born . However , this doesn’t happen to everyone , so scientists guess there must be another reason why people become left-handed . One idea is that people usually get right-handed from their parents . If a person does not receive the gene（基因）for right-handedness , he / she may become either right-handed or left-handed according to the chance and the people they work or live with .
Though right-handedness is more common than left-handedness , people no longer think left-handed people are strange or unusual . A long time ago , left-handed children were made to use their right hands like other children , but today they don’t have to .
小題1: After studying works of art made at different times in history , the scientists found       .
A. art began from 1, 500 B.C.
B. the works of are ended in the 1950s
C. most people shown in the works of art are right-handed
D. most people shown in the works of art are left-handed
小題2:How many people in the world are left-handed now ?
A．Less than one sixth .B．More than a half .
C．About 40% .D．The passage doesn’t tell us .
小題3:What is the left hand for most people used to do ?
A．It’s used to find or hold things .
B．It’s used to work with things .
C．It’s used to make a person’s eyes work together .
D．It’s the centre for thinking and doing problems .

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people and many animals like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper - a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey and the wax always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined(堅(jiān)定的) in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
小題1:Why is it difficult to find a wild bees' nest?
A．It's small in size.B．It's hidden in trees.
C．It's covered with wax.D．It's hard to recognize.
小題2:What do the words "the follower" in Paragraph 2 refer to?
A．A bee.B．A bird.C．A honey seeker.D．A beekeeper.
小題3:The honey guide is special in the way              .
A．it gets its foodB．it goes to church
C．it sings in the forestD．it reaches into bees' nests
小題4:What can be the best title for the text?
A．Wild BeesB．Wax and Honey

Can you remember the day when you spoke your first word? If you can, you are unusual. Try to imagine what first few months of your life were like. I am sure you just spent most of your time eating, sleeping and crying. As you grow older, you were awake more of the time. It took your parents more time to play with you and talk to you. You watched and listened curiously. You began to know that people made certain sounds to go with certain things.
Then you began to try making the sounds you heard. And step by step you were able to make the right sound for one thing.On that day you came to understand the secret of language. The secret is that a certain sound means a certain thing. One sound might be as good as another. But it is no good as a word unless everybody agrees on its meaning. Only when a group of people use the same set of sounds of things, can they understand each other. Then, and only then do these people have a LANGUAGE.
After you found the secret of language, you learned words. Some of the words meant things, such as BOOKS, CHAIRS and SHOES. Some words meant doing things, such as GO and SWIM. And other words describe things, such as GOOD and DIRTY. Soon you learned to put words together to express one’s idea, such as “I want to go out and play with my friends.” This is language. By means of language people can communicate. So we say languages are means of communication.

Blogs (博客) are the place where young people go to show their hearts, to express their anger, sorrow or disappointment, and even to gossip (說別人的閑話).
Many people enjoy the freedom in blogging. Some, however, find that putting one’s life online can have a price. The blogs of some students in America were stopped by the government for some time because they posted threatening words to their teachers on their blogs.
A recent study finds that nearly a fifth of teens who surf the Internet have their own blogs. And 38 % of teens say they read other people’s blogs. By comparison, about a tenth of adults have their own blogs and a quarter say they read other people’s online magazines.
With the development of the Internet, more and more people will be attracted by blogging.
In another study, 79% of teens agree that people at their age aren’t careful enough when giving out information about themselves online. Besides, careless blogging can also influence blog readers. When you are angry or unhappy, your blog is the first place you turn to. The words you post then may not be rational which you may regret later. To minimize (使減到最小) the negative influence, change the safety setting and make such posts “personal” so that only you can read them.
As long as you are careful with what you post, blogging is a great means of staying in touch with friends and displaying one’s creative works.
小題1:Blogs are the place where people __________.
A．go online to have a chat

It can greet people, show DVDs and hand out balloons. “Ubiko”, a robot-on –wheels with a catlike face, is joining the crew of temporary workers supplied by a Japanese job-referral company, Ubiquitous Exchange, to stores, events and even weddings. Next month, the 44-inch tall robot will be selling mobile phones at a store.
Ubiko can be hired as a temporary worker for two hours for 105,000 yen, or $890.
“We see this as serious business. There are jobs that robots are better at,” Akiko Sakurai said “people do develop a relation with the robot, and it’s lovable.”
The $255,000 robot, which is equipped with a camera and sensors, greets customers with a nasal electronic voice, shows DVDs with a projector in its head and hands out balloons and other goods with wireless remote-controllable arms.
Ubiko sounds like a Japanese female name, which often ends with “ko”.
Tmsuk, the Japanese company that makes the robot, sold three last month to hospital, where they are working as full-time, rather than temporary, receptionists and guides. One of the hospital’s robots serves as a receptionist and has been programmed to greet visitors. It also has a touch-panel(控制板) on its body, and visitors can use it to get directions for where they want to go. 
“Just give it electricity, and a robot can work for long hours, even do repetitive work, and you don’t have to worry about labor laws,” Sudo said.
Japan’s lower birth rate means that in the coming years it could face a labor shortage, and some experts believe robots could be part of the key to that problem. Robots are very popular in Japan partly because of the popularity of cartoons that describe robots as friends and assistants to humans.
小題1:The news report is mainly to _________________.
A．give praise to advanced robots in Japan
B．introduce the development of robots in Japan
C．tell readers the advantage of the robots in Japan

小題4:Which of the following makes robots more popular in Japan?
A．The low price of robots.
B．The interesting shapes of robots.
C．The function of showing DVDs and handing out balloons.

In some urban centers, workholism 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 don’t do this because they have to; they do it because they want to.
Workholism can be a serious problem. Because true workaholics (工作狂) would rather work than do anything else, they probably don’t know how to relax.
Is workholism 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 keep them busy and creative.
Why do workaholics enjoy their jobs so much? There are several advantages to work. Of course, 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’ve produced a challenging piece of work and are able to say, “I made that.” Psychologists claim that work gives people an identity through participation in work, they get a sense of self and individualism. In addition, most jobs provide people with a socially acceptable way to meet others. Perhaps some people are compulsive about their work, but their addiction seems to be a safe-even an advantageous-one.
小題1:The passage indicates that workaholics ______.
A．just know work but nothing else
B．a(chǎn)re willing to work hard for long hours without pay
C．find their work provide them more satisfaction and self-confidence than how much they are paid
D．has the work with more responsibility than others
小題2:One of the reasons that some people are not willing to quit their jobs even in their eighties and nineties is that ______.
A. they are in the need of financial security
B. they would rather work than be disturbed by domestic affairs
C. they long for a sense of identity and being accomplished
C. they may have health problems from sheer boresom
小題3:This passage is mainly about ______.
A．workaholics are usually successful people, but their lives are in a mess
B．workholism can lead to serious problems but it can also create a joyful life
C．people who are absorbed in their work may enjoy movies, sports and other kinds of entertainment
D．those who work even under difficult conditions may be very happy
小題4:It can be inferred from the passage that ______.
A．in the eyes of all the common people workaholics are peculiar
B．to workaholics, work is the sole source of happiness
C．a(chǎn) piece of challenging work may provide the workaholics a sense of satisfaction
D．workaholics are as addicted to their job as other people are to drugs or alcohol
