“Get your hands off me, I have been stolen,” the laptop, a portable（便攜式的）computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts（警報(bào)）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 to 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(版本) 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 (主管) 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, please report me now.”
The Retriever software package(軟件包), which costs $29.95 (￡21) but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access 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（刪除）data remotely or lock down the computer.
【小題1】The expression “to give the thief a piece of their mind” 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
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 summarize 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.

WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand.
Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios.
The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day.
"The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore.
"Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday.
"It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle."
The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms.
【小題1】What's the research really about?

A．Boys and girls. B．Food and weight. C．Sleep and health. D．Screens and fat.
【小題2】What's the result of less sleep for teenage boys?
A．Bigger waist and more fat in the body.
B．An increase in weight and height.
C．More concerned with their diet.
D．A decrease in bone and muscle.
【小題3】From the sixth paragraph we can infer that ______.
A．girls usually sleep less and have healthier lifestyles than boys
B．the researchers expected to see the same result in girls
C．peoples' diet has a great effect on their health
D．boys are usually lazier than girls
【小題4】Who would be the most pleased to hear the news?
A．Teachers. B．Girls. C．Parents. . D．Boys.

Below is a selection from a popular science book.
If blood is red, why are veins (靜脈) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
Which works harder depends on whether you are busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don't they grow back in grown-ups?
Baby (or "milk") teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they’re gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity. Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards — their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little or, more often, become more bent and curved.
Why does spinning（旋轉(zhuǎn)） make you dizzy (眩暈的)?
Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you're moving while you're not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s "use it, or lose it”! It's not that exercise makes you healthy; it's more that a lack of exercise leaves your body weak and easily affected by disease.
【小題1】What is the color of blood in a vein near the surface of the skin?

A．Blue. B．Light yellow. C．Red. D．Dark reddish purple.
【小題2】Why do some old people look a little shrunken as they age?
A．Because their spine is in active use.
B．Because they are more easily affected by gravity.
C．Because they keep growing backwards.
D．Because their spine becomes more bent.
【小題3】Which of the following statements about our brain is true?
A．In the long run, our brain probably works harder than our heart.
B．When our brain senses the spinning, we will fell dizzy.
C．The brains of the other mammals are as complex as those of humans.
D．Our feelings and emotions come from the most developed area in our brain.
【小題4】What is the main purpose of the selection?
A．To give advice on how to stay healthy.
B．To provide information about our body.
C．To challenge new findings in medical research.
D．To report the latest discoveries in medical science.

The way we get about has a deep influence on the way we live－affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true?
Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演員) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.
The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus.
【小題1】The passage is mainly about ________.

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
【小題1】What function isn’t understood by most people on Facebook?

A．Surfing the Internet. 
B．Setting safety protection. 
C．Sharing personal information. 
D．Making foreign friends. 
【小題2】What can we learn about Facebook according to the text?
A．Its process of privacy-setting is too complex. 
B．It displays everything people post. 
C．It lacks privacy controls and security features. 
D．Its post is designed for technical people. 
【小題3】What advantage can we get from making friend lists?
A．We can avoid our bosses adding us as friends. 
B．We can share applications with friends. 
C．We can separate acquaintances from family. 
D．We can hide different information from different friends.

C
When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure--and so soon--that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead--take me away” when it is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead---take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.
【小題1】What is the function of the first paragraph?

B．When an ant dies, it can tell others using a certain chemical.
C．A living ant can pretend to be dead using a special chemical.
D．Ants often use chemicals to communicate with each other.
【小題4】Which of the following descriptions about Dong-Hwan Choe is right?
A．Choe did this study in order to stop ants from invading new places.
B．Choe is a biologist who is only interested in animals, especially in ants.
C．Choe first came up with an idea to explain this ant behavior，and then did some tests to prove his theory.
D．Choe did the research on this ant behavior on his own.

It’s 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his e-mail and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write ... Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John’s house, and he is a telecommuter —  he works at home, communicating with the workplace through the Internet.
Like John, millions of people — and their employers — are finding that telecommuting is a great way to work. Telecommuters can follow their own timetables. They work in the comfort of homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems.
Jobs that are suited to telecommuting include writing, design work, computer programming and accounting. If a job is related to working with information, a telecommuter can probably do it.
【小題1】From the passage we can learn that John does his job           .

A．by telephon B．through the Internet
C．in his office D．a(chǎn)way from home
【小題2】One of the advantages of telecommuting is that you can        .
A．work for several employers B．enjoy a lot of traveling
C．get along well with other workers D．work on your own schedule

A．their employers can save money
B．their employers will give them a higher pay
C．they can get more work experience
D．they will have a longer paid holiday
