When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much.
But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line.
Ergonomics is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that’s working on a factory assembly line or sitting in front of a computer.
The monitor
You should not have to tilt(傾斜) your neck up or down to lock at the screen. Your eyes should be level with the top of the screen.
How far away should you sit? Reach your arm out so your fingertips just touch the screen.
The keyboard
It should be directly in front of you. Don’t unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists “neutral,” which means straight, not bent. This puts less strain on your nerves and muscles.
Arms should be close to the body. Don’t look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don’t have to reach for it.
The chair
Your feet shouldn’t dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there.
The Body
If you think of your body as a collection of right angles when you sit at a computer, you should be just fine.
Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat.

A.a(chǎn)voiding pains caused by using PCB.the science of ergonomics
C.illness caused by a computerD.how to keep fit

Artistic Skates
Artistic roller skates are made up of a leather boot, very strong sole plate, and a jump bar that adds extra force. The boot sits a few inches above the ankle, providing more support for the foot.
Jam Skates
Jam skates are the most different roller skates because of their special low-cut design and lack of toe stop. That’s right: there is no brake. But the original jam skate design was different, resembling an artistic skate. Jam skating is more about personal expression rather than speed skating. The free-flowing movements of jam skating have been given many names. But regardless of its name, jam skating has always been about expression and passion.
Speed Skates
A speed skate resembles a shoe. The cut of the boot is lower. Speed skates typically offer lightweight plates to reduce exhaustion for skating long distances. Jam skates have preferred speed skates because they offer a similar design and freedom of movement. The most obvious difference is that a speed skate features a toe stop, unlike a jam skate that uses a toe plug.
Rhythm Skates
Rhythm skates are similar to jam skates. The difference between them lies in the boot design. In fact, the boot design looks very similar to an artistic skate, essentially providing you with the ankle support benefits of an artistic skate, but the freedom of movement of a jam skate. If you want a skate that allows you to move to the beat, which added ankle support, the rhythm skate is the ideal choice.
小題1:Which of the following is NOT a feature of jam skates?
A.They have no brake
B.They lack a toe stop
C.They have no toe plug.
D.They have a unique, low-cut design.
小題2:If you want to skate to music, which of the following is the best choice?
A.Rhythm skates B.Jam skates C.Speed skates D.Artistic skates
小題3:Speed skates are popular with jam skates because _____.
A.they have a high boot cut
B.they allow free-flowing movement.
C.they are able to stabilize the foot
D.they can help jam skates reduce tiredness.
小題4:What is a common feature of rhythm and jam skates?
A.They both offer some support for the ankles.
B.They both have a similar boot design.
C.They are both suitable for free-flowing movement.
D.They are both about personal expression and passion.
小題5:What can you learn from the passage about jam skates?
A.The original jam skate design has hardly changed.
B.The original jam skate design was similar to an artistic skate.
C.Jam skates have gradually become a type of speed skate.
D.Jam skating has many names because it’s about expression and passion.

Do you want to live another 100 years or more? Some experts say that scientific progress will one day help humans to last tens of years longer than what is now seen as the natural limit(限制)of the human life span(壽命).
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate(保守估計).”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said progress in using genes as well as nanotechnology(納米技術(shù))makes it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who research into aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also disagree on what kind of life the super aged might live. “It remains to be seen whether you could be healthy enough to have good quality of life when you pass 120.” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
小題1:By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A.they believe that there is no limit of living
B.they are sure to find the truth about long living
C.they have got some ideas about long living
D.they are able to make people live beyond the present life span
小題2:Donald Louria’s attitude toward long living is that_____.
A.people can live from 120 to 180
B.it is still doubtful how long humans can live
C.the human body is designed to last about 120 years
D.it is possible for humans to live longer in the future
小題3:The underlined “ it” (Para. 4) refers to_____.  
A.a(chǎn) great push
B.the idea of living beyond the present life span
C.the idea of living from 200 to 300
D.the conservative estimate
小題4:What would be the best title for this text?
A.Living longer or not
B.Science, technology and long living
C.No limit for human life
D.Healthy lifestyle and long living

We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of energy for our planet. It causes the evaporation (蒸發(fā)) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms(生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
小題1:According to the passage, the root( 根本的) cause for weather changes on the Earth is         .
A.the atmosphere surrounding the Earth
B.water from oceans and lakes
C.energy from the Sun
D.greenhouse gases in the sky
小題2:Only a small part of the Sun’s energy reaches the Earth’s surface because most of it is         .
A.a(chǎn)bsorbed by the clouds in the lower atmosphere
B.reflected by the gases in the upper atmosphere
C.lost in the upper and lower atmosphere
D.used to evaporate water from the oceans and lakes
小題3:We learn from the passage that         .
A.a(chǎn)ll living things on the Earth depend on the Sun for their food
B.a(chǎn) forest looks dark in winter because it absorbs solar energy
C.only 0.023% of the energy from the Sun is made use of on the Earth
D.greenhouse gases allow heat energy to escape from the Earth’s surface

“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft (the crime of stealing): a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts (warning) on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “l(fā)ost or stolen” sign appears on its screen when it is started. Under the latest version of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely (遠(yuǎn)程地) switch to an alternative (可替換的) password immediately if they fear that the thief has also got hold of the access (進入, 使用) details.
If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.
小題1:The underlined expression “to give the thief a piece of their mind” in Paragraph 2 can be understood as “_______”.        
A.to give the thief an alert mind
B.to express the owners’ anger to the thief
C.to remind the thief of his conscience (良心)
D.to make the thief give up his mind
小題2:Different from other security software, Retriever can _______.
A.record the stealing process
B.help recognize the lost laptop
C.lock down the computer remotely
D.send a spoken message
小題3:One function of the program is that it allows the owner to _______ at a distance.                         
A.change some access details for switching on the laptop
B.turn on the laptop by using the original password
C.operate the laptop by means of an alternative password
D.erase the information kept in the stolen laptop
小題4:Which of the following can best sum up the main idea of the passage?
A.With no Retriever, thousands of laptops are stolen every year.
B.A new software provides a means to reduce laptop theft.
C.Retriever has helped to find thieves and lost computers.
D.A new program offers a communication platform with the thief.
小題5:What does the word “it” in Paragraph 4 refer to?
A.the alert messageB.the computer
C.the programD.the laptop

Without plant, people could not live. We eat plants. We breathe the oxygen(氧氣)that plants produce. And we need plants for another reason: we need them for their beauty.
Imagine a world with no plants. Imagine no flowers with their sweet smells, their beautiful colors and their lovely shapes. Imagine when the wind blows, not being able to hear the leaves in the trees or watch the branches sway(搖擺)from side to side.
Everywhere people need the beauty of plants. That is why we have parks full of trees and flowers. That is why people always try to design houses with room for some grass and a garden.
Do you talk to your plants? Do you give them love and attention?
Peter Tompkins and Christopher Bird, writers of a book called THE SECRET LIFE OF PLANTS, tell of an experiment in which two seeds were planted in different places. While the plants were growing, one plant was given love and hopeful ideas. The other plant was given only hopeless ideas. After six months, the loved plant was bigger.

A new generation addiction is quickly spreading all over the world. Weboholism(醉心于網(wǎng)絡(luò)), 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(強迫性的)behavior that could affect the social and physical life of computer users. This obsessive behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.
They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at schools. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.
They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual(虛擬的)life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.
Because of the change in their behavior, they begin to isolate(孤立 themselves from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect the whole world.
小題1:The main idea of the passage is about _______.
A.the cause of weboholismB.the advantage of weboholism
