Autumn blues? Let the sunshine in falling leaves, flowers, and cold winds. For many people late autumn can be a season of depression.
Those who suffer from “ the autumn blue” are often extremely tired, lack energy, need more sleep, feel increased appetite and gain weight. "The exact cause of this condition, often called seasonal depression or seasonal affective disorder (SAD), is not known yet," says Chen Jue, associate professor at Shanghai Mental Health Center. "But recent studies indicate that weather change is influential and strongly suggest that this condition is caused by changes in the availability(得到) of sunlight."
One theory is that with decreased exposure to sunlight, the biological clock that regulates mood, sleep, and hormones is delayed, running more slowly in winter. Exposure to light may reset the biological clock. Another theory is that brain chemicals that transmit information between nerves, called neurotransmitters (for example, serotonin), may be altered in individuals with SAD. It is believed that exposure to light can correct these imbalances. "It is a sad season, but you can try to make it happy. Remember, spring always lives in your heart," Chen says. “Going outdoors to get some sunlight may reduce the tension that brings you the low spirits. Relax at work. Stretch, breathe deeply. Take a tea break. Think of your next vacation. Color treatment also works in handling low mood. Music also plays a role in treating autumn blues.”

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
D．introduce a newly-developed robot in Japan
小題2:We can learn from the passage that ____________.
A．the price of Ubiko is $890
B．the purpose for a store to buy the robot is to greet customers
C．Ubiko can work for long hours without using energy
D．three robots have been sold to a hospital
小題3:Which of the following can be inferred about Ubiko according to the passage?
A．It sounds beautiful, like a girl’s voice.
B．It is named after a Japanese girl.
C．It will have a wider market.
D．It was designed for hospitals.
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.
D．Cartoon’s showing good relationship between robots and humans.
小題5:Which of the following about Ubiko is NOT true?
A．It has a face of female.
B．There is a projector in its head.
C．It is equipped with a camera and sensors.
D．It has wireless remote-controllable arms.

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

Everyone knows about straight-A students. We see them frequently in TV situation comedies and in movies like Revenge(報復)of the Nerds. They get high grades, all right, but only by becoming dull laborers, their noses always stuck in a book. They are not good at social communication and look clumsy while doing sports.
How, then, do we account for Domenica Roman or Paul Melendres?
Roman is on the tennis team at Fairmont Senior High School. She also sings in the choral group, serves on the student council and is a member of the mathematics society. For two years she has maintained A’s in every subject. Melendres, a freshman at the University of New Mexico, was student-body president at Valley High School in Albuquerque. He played soccer and basketball well, exhibited at the science fair, and meanwhile worked as a reporter on a local television station. Being a speech giver at the graduation ceremony, he achieved straight A’s in his regular classes, plus bonus points for A’s in two college-level courses.
How do super-achievers like Roman and Melendres do it? Brains aren’t the only answer. “Top grades don’t always go to the brightest students, ” declares Herbert Walberg, a professor of education at the University of Illinois at Chicago, who has conducted major studies on super-achieving students. “Knowing how to make the most of your innate(天生的)abilities counts for more. Much more.”
In fact, Walberg says, students with high IQ sometimes don’t do as well as classmates with lower IQ. For them, learning comes too easily and they never find out how to get down.
Hard work isn’t the whole story, either. “It’s not how long you sit there with the books open, ” said one of the many-A students we interviewed. “It’s what you do while you’re sitting.” Indeed, some of these students actually put in fewer hours of homework time than their lower-scoring classmates.
The kids at the top of the class get there by mastering a few basic techniques that others can readily learn.
小題1:The underlined word “nerds” can probably be________ .
A．dull bookworms lacking sports and social skills
B．successful top students popular with their peers
C．students with certain learning difficulties
D．born leaders crazy about social activities
小題2:What can we conclude from the first paragraph?
A．Most TV programs and films are about straight-A students.
B．People have unfavorable impression on straight-A students.
C．Everyone knows about straight-A students from TV or films.
D．Straight-A students are well admired by people in the society.
小題3:Some students become super-achievers mainly because_________ .
A．they are born cleverer than others
B．they work longer hours at study
C．they make full use of their abilities
D．they know the shortcut to success
小題4:What will be talked about after the last paragraph?
A．The interviews with more students.
B．The role IQ plays in learning well.
C．The techniques to be better learners.
D．The achievements top students make.
小題5:What can we infer from the passage?
A．IQ is more important than hard work in study.
B．The brightest students can never get low grades.
C．Top students certainly achieve all-around developments.
D．Students with average IQ can become super-achievers.

The laptop is a machine which can be a mobile office；it can be used to entertain us and people can play computer games on them. One machine can perform many tasks at the same time. As technology grows，the size of the new laptop machines is decreasing. Now laptops are lighter，have smaller screen sizes，and perform better. Smaller screen laptops，which are more convenient to take along with，have been specially designed for professionals. Huge display screen laptops are still used by graphic(繪畫的)designers and those who like playing computer games.
Laptops are advanced machines，and they can be very expensive. When we spend much money on something，we should take good care of it. I know some people who buy a new laptop every year. The reason they do this is that the old one either is broken or has some problems which cannot be fixed. Common problems are the breaking of the screen，the breaking of joints of the laptop，display problems，and keyboard problems.
Different problems will always come up with machines，and they cannot be avoided(避免)．Old machines will always have to be replaced by new ones. However，if we are more careful and handle our laptops with care，they will last for a longer period of time，and they will perform better. This is not a hard thing to do，but it will greatly increase the life and performance of laptops.

Imagine that the genome （基因組） is a book．The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels．There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube．This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear（細胞核） that fits easily upon the head of a pin．
The idea of the genome as a book is not, strictly speaking, even a metaphor．It is true to a great extent．A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings．So is a genome．The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time．
While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules （分子）．
The genome is a very clever book, because in the right condition it can both photocopy itself and read itself．
小題1:How do human genomes read according to the passage?___________
A．Only from left to right．
B．Only from right to left．
C．From both directions at the same time．
D．From one direction at a time．

A．is as long as the River Danube
B．can be easily placed on the head of a pin
C．is coded with an alphabet of four letters
D．is smart enough to read and take photos of itself
小題3:It can be concluded that the passage is mainly written for ______．
A．specialists in the field
B．general readers
C．natural scientists
D．readers with professional knowledge
小題4:The real purpose of the author’s comparison of the genome to a book is _____．
A．to focus on the differences between the two
B．to lay emphasis on the similarities between the two
C．to simplify the concept of the human genome
D．to give an exact description of the human genome

For some people, the prospect of starting college, especially going away to school, is scary. It’s probably the first time that you’ll be totally responsible for your own schedule. What if you intend to go to college but just don’t feel ready to start yet-for whatever reason-and you don’t want to take on a full-time job after graduation? You might want to take a year off to pause and regroup. This practice is common in some countries, like the United Kingdom, where it’s called a “gapyear”.
Taking time off doesn’t mean you should ignore the idea of applying to college. In fact, you may want to consider making your college plans before you become involved in other things, especially if you’ll be travelling. Apply to schools and make your choice, then ask for a deferred admission. Rachel took a year off and worked in New York City between college and medical school. She says that she had to be extremely well organized about planning for medical school so she didn’t miss any of her deadlines. “Not only did I have to apply to schools and make plans to take my MCAT exams, I also had to make all my living arrangements and other plans for my year off!”
Even if you decide not to apply to college, it can be a great idea to take a year to do something you may not have an opportunity to do again. Lots of volunteer organizations would welcome your time and energy and would provide you with a wonderful learning experience. If you take a year off you will learn some great life skills-like living on a tight budget! If you take a year off you’ll pay your way while you are traveling or doing volunteer work.

All Eskimos live most of their lives close to sea or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes, or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen (地衣) grow on the rocks, and where there is enough soil, grass, flowers, and even small bushes manage to live. No trees can grow on Eskimo land, so geographers sometimes call it the Arctic plains. There are some animals in Eskimo land, such as rabbits, which eat the plants. Other animals, like the white fox and the gray wolf, eat the rabbits. The Eskimo is a meat-eater, too, and may even eat a wolf when food is scarce.
The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall are almost too short to be noticed. Summer is the best time, as food is usually plentiful. But it is also the time when Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store, for seldom can enough animals be killed in winter to feed a family.
The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21st and August 21st the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sunshine at all. Around Oct. 21st the Eskimos of Northern Greenland see the sun set directly south of them, and they don’t see it again until February 22nd. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker.
Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and moon provide a little light. The northern lights also help the Eskimo to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo’s eyes.
小題1:Which of the following statements is NOT true?
A．Eskimos do not usually eat wolves.
B．Eskimos like to chase one another.
C．Eskimos depend heavily on water.
D．Eskimos are meat-eaters.
小題2:What’s the meaning of the underlined words “pitch-black” in Paragraph 4?
A．Dark with a little light.
B．A little dark.
C．Not dark at all.
D．Extremely dark.
小題3:From the passage, we can infer all of the following EXCEPT that_______.
A．Eskimos are more likely to eat wolves in summer
B．Eskimo women are responsible for housework
C．meat is the main source of food for the Eskimo
D．hunting is an important part of Eskimo life

The Internationa1 Space Station allows astronauts to live in space for extended amounts of time, enabling them to explore the outside universe and conduct many experiments. However, nothing like that exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what lies undersea for very short periods of time.
They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon.
Jacques has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge l67ft. ship, named ‘Sea Orbiter’, consists of two areas—one above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to circumvent the globe.
Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD player! And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an accomplished chef, plans on cooking them delicious meals every day.
The biggest problem to this giant ship is the cost, which is expected to be over $500 million—per ship! However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global warming and a vital supply for food and medicine in the future, is confident he will be able to convince governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon!
小題1:Why can’t ocean researchers explore the deep oceans for a long time?
A．Because they can’t stand the high water pressure.
B．Because it’s too cold in deep ocean.
C．Because time for experiments is too limited.
D．Because it’s dangerous to observe the sea life.
小題2:The underlined word “circumvent ” probably means     .
A．fly awayB．go aroundC．travel throughD．move into
小題3:From the fourth paragraph we can learn that     .
A．Jacques intends to design the ship mainly for sightseeing and traveling
B．living a comfortable life helps to do the ocean research quickly
C．it’s much more expensive to eat freeze-dried food
D．researchers on Jacques ’ ship will live more comfortably than astronauts
小題4:In Jacques’ opinion, which of the following is not the purpose of the undersea research?
A．To find supply for food in the future.
B．To find supply for medicine in the future.
C．To draw governments’ attention to the construction of the ship.
D．To solve the global warming.
小題5:Which of the fol1owing would be the best title for the text?
A．Sea Orbiter—the ship of the future
B．A new way to explore the deep oceans
C．A great architect—Jacques Rogerie
D．Travel around the globe in Sea Orbiter
