Have you ever walked outside thinking it was one temperature but quickly discovered it felt colder? That is because of the “wind chill” effect.
Wind chill is how cold people and animals feel when they are outside, not the actual temperature on the thermometer(溫度計(jì)). It is based on how quickly your body loses heat when it is exposed to wind and cold. When the wind is strong, your body quickly loses heat, making the temperature of your skin drop.
When scientists first started calculating wind chill, they used research conducted in 1945 by explorers to Antarctica who measured how quickly water froze outside.
But water freezes faster than exposed skin, so the wind chill index based on that data wasn’t accurate.
In 2001, the US government began to measure wind chill more precisely by testing how quickly people’s skin froze.
Twelve volunteers were placed in a chilled wind tunnel. Equipment was stuck to their faces to measure the heat flow from their cheeks, forehead, nose and chin while they walked three miles per hour on a treadmill(跑步機(jī)).
The experiment revealed how quickly exposed skin can be damaged, particularly unprotected areas like your fingers, toes, the tip of your nose and your ear lobes. In fact, 40 percent of your body heat can be lost through your head! Signs you might have frostbite(凍瘡) are when the skin turns white or pale and you lose feeling in that area.
The information collected from the volunteers helped scientists work out the math to compute wind chill. It involves wind speed and air temperature.
If, for example, the temperature outside is zero degrees Fahrenheit and the wind is blowing at 15 miles per hour, the wind chill is calculated at 19 degrees below zero. At that wind chill temperature, exposed skin can freeze in 30 minutes.
You can find a calculation table at www.nws.noaa.gov/om/windchill/index.shtml.
Experts advise in cold weather that you wear loose-fitting, lightweight, warm clothing, worn on top of each other. Air caught between the clothes will keep you warm. The best cold-weather coats have head coverings made of woven material that keep out water. So next time the temperature drops and you want to play outside, listen to your parents when they tell you to wrap up warm!
【小題1】 According to the text, wind chill _______.

A．means how fast exposed skin freezes
B．doesn’t affect your head as much as other body parts
C．changes according to the temperature on the thermometer
D．changes from person to person depending on their health
【小題2】 When might a person have frostbite according to the passage?
A．When his skin turns red and he loses feeling in that area.
B．When he is running faster and he is losing strength quickly.
C．When his face is exposed and quickly loses heat even indoors.
D．When his skin turns pale and he has no feeling in that area.
【小題3】 What factors influence wind chill?
A．A person’s body temperature and will speed.
B．Wind speed and a person’s strength.
C．Air temperature and wind speed.
D．The location and air temperature.
【小題4】 What can we conclude from the passage?
A．It was in 1945 that scientists first began to calculate wind chill.
B．Compared with water, people’s exposed skin freezes more slowly.
C．The wind chill index based on Antarctica data is considered a standard.
D．With the development of technology, many previous researches have been proven wrong.

       Gauri Nanda sees a wearable computer as a handbag—one that’s built out of four-inch squares and triangles of fiber, with tiny computer chips embedded（嵌入） in it．It looks, feels and weighs like your typical leather purse．

       That’s where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet．It can review the weather report and suggest that you grab an umbrella．This purse can even upload your favorite songs onto your scarf．

       Sure, a computing purse and scarf set may seem like the stuff of science fiction．But these devices, part of next generation of wearable computers, could become commonplace within a few years．DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes．And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle．

       As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs．Unlike their predecessors, these new wearable computers also make economic sense．When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse．

       Here’s how the bag works: You place a special radio-signal-transmitting chip on to your wallet．A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet．In turn, sensors on your purse’s handles will notify the computer that you’ve picked up the purse and are ready to go．

       Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring—and even, increasingly, for consumers at large．Indeed, more people will want to cross that bridge in the coming years--- making for a booming market for wearable computers that don’t like something out of science fiction．

1．Which of the following describes a wearable computer?

       A．It can be washed in a washing machine．

       B．It is much heavier than a leather purse．

       C．It can download songs from the Internet．

       D．It is made of clothes conducting electricity．

2．According to the passage, these new wearable computers ______．

       A．require users to operate on the stomach

       B．pick up the signals through wires and chip

       C．a(chǎn)re being applied in some different areas now

       D．a(chǎn)re smarter but more expensive than the old ones

3．What does the underlined sentence in the last paragraph mean?

       A．These new wearable computers have become fashionable．

       B．People would like to learn more about these new computers．

       C．These new wearable computers promise to sell well in the future．

       D．The idea of these purse-like computers comes from science fiction．

4．The purpose of the passage is ______．

       A．to introduce a new kind of compute

      B．to explain the function of computers

       C．to compare different types of computers

       D．to show how high technology affects our life

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.

　　Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person's thoughts.

　　In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

　　“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”

　　The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (頭皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

　　Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

　　He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

46. BCI is a technology that can ________.

A. help to update computer systems B. link the human brain with computers

C. help the disabled to recover　　　　　　　　　　　　　　 D. control a person's thoughts

47 .How did Tavella operate the wheelchair in the laboratory?

A. By controlling his muscles.　　　　　　　　　　　　　　 B. By talking to the machine.

C. By moving his hand. D. By using his mind.

48.Which of the following shows the path of the signals described in Paragraph 5?

A. scalp → computer → cap →wheelchair

B. compute → cap → scalp →wheelchair

C. scalp → cap → computer →wheelchair

D. cap → computer → scalp →wheelchair

49.The team will test with real patients to ________.

A. make profits from them B. prove the technology useful to them

C. make them live longer D. learn about their physical condition

50.Which of the following would be the best title for the text?

A. Switzerland, the BCI Research Center

B. New Findings About How the Human Brain Works

C. BCI Could Mean More Freedom for the Disabled

D. Robotic Vehicles Could Help to Cure Brain Injuries
