    【题目】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 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 (头皮) 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.

    【1】BCI is a technology that can ________.

    A. help the disabled to recover

    B. control a person's thoughts

    C. help to update computer systems

    D. link the human brain with computers

    【2】How did Tavella operate the wheelchair in the laboratory?

    A. By talking to the machine.

    B. By controlling his muscles.

    C. By using his mind.

    D. By moving his hand.

    【3】Which of the following would be the best title for the text?

    A. Robotic Vehicles Could Help to Cure Brain Injuries

    B. BCI Could Mean More Freedom for the Disabled

    C. New Findings About How the Human Brain Works

    D. Switzerland, the BCI Research Center

    【题目】Outdoor air pollution is an obvious danger because it’s hard to miss.Auto gases, industrial waste, city smog—everyone knows they’re a health hazard(危险) and a call for solutions is on everyone’s lips.But there’s another threat just as perilous— a hidden threat(威胁) we are usually unaware of.We’re speaking about the threat of indoor air pollution.

    The dangers caused by indoor air pollution are too often underestimated(低估) and overlooked.According to a recent study, indoor air pollution can be many times higher than outdoor air pollution.A similar study by the Environmental Protection Agency shows that, in general, the air in our homes and offices is two to five times more polluted than outdoor air.

    Scientific studies have found that indoor air pollution exacerbates(恶化) the symptoms of asthma(哮喘), and contributes to causing nausea(恶心), headaches and damage to the central nervous system.Evidence has even been found linking poor indoor air quality to certain cancers.Children who spend eighty percent of their time inside are particularly affected by indoor air pollution.

    Cigarette smoke, chemical fertilizers(肥料), perfumes and clothing that has been dry-cleaned may contribute to indoor air pollution.Building materials—including paint and glue—are also contributors.

    And homes aren’t the only indoor areas affected by this danger.Offices are affected too—sometimes more so—with their copy machines and printers, inks and processing solutions (显影液)and so on.

    Fortunately there are many ways to reduce indoor air pollution and improve indoor air quality in your home and office.A major first step would be the use of an air purifier(净化器).

    【1】What does the underlined word “perilous” mean?

    A.Nervous. B.Similar. C.Obvious. D.Dangerous.

    【2】The author mentions some studies in Paragraph 2 to show indoor air pollution__________.

    A.is recently overestimated

    B.is very common and serious

    C.has drawn people’s attention

    D.is linked to many serious diseases

    【3】Which of the following is the usual contributor of air pollution in our homes?

    A.Smoking. B.Printing.

    C.Copy machines.D.Processing solutions.

    7.【4】What would be discussed in the paragraph that follows?

    A.An introduction to the air purifier.

    B.Other dangers of indoor air pollution.

    C.Other sources of indoor air pollution.

    D.More solutions to the problem of air pollution.

    【题目】That woman carried a new blanket (毛毯) over her arm. Wordlessly, she gave it to me.

    “Is it finished?” I asked.

    She shook her head. “No. It is ready,” she replied. I handed her the money and took the blanket.

    “It is beautiful, so skillfully woven (编织),”I said to my mother.“But what did she mean when she said it was not finished? How can it be ready if it is not finished?”

    “I will tell you later,” my mother said, “but first I will take you to the Navajo(纳瓦霍) village.”

    We went down to the village. A group of young men were making sand pictures. We walked through the whole village, watching the different things the people were doing.

    It was not until that evening that my mother finally explained the Navajo woman's words.

    “Did you notice anything about the things the people were making?” my mother asked.

    “What should I have noticed?” I looked at her and asked.

    “Each thing the Navajo make has one small part that is not complete. The designs in their sand pictures are often not perfectly done, for example—the line of a circle may not quite close. If you look carefully at your blanket, you will probably find a stitch (一针) missing.”

    I took the blanket off, but it looked as perfect as any design could be. Then suddenly, I noticed that sure enough a stitch was missing!

    “But why do the Navajo intentionally leave some tiny part unfinished?” I asked.

    “They believe that when anything is completed or finished, it means the end has come — it will not be perfect until then. Then too, with a circle, they believe that they must leave a pathway for the bad spirits to run away and the good spirits to come in. So, often, they do not make the line close.”

    【1】The blanket the author received _____.

    A. was poorly woven B. made her think a lot

    C. cost her a lot of money D. was finished, but not ready

    【2】Why was the author shown around the village?

    A. To buy more things made by the Navajo.

    B. To make friends with some of the Navajo.

    C. To have a deeper understanding of the Navajo.

    D. To look for the woman who sold her the blanket.

    【3】Which of the following may the Navajo believe?

    A. A stitch in time is very important. B. Life only becomes perfect when you die.

    C. He who makes no mistake is a perfect man. D. You must always try to make your life complete.

    【4】What's the main idea of the text?

    A. The Navajo are good at making things.

    B. The Navajo are brave and hard-working.

    C. A blanket tells a lot about the Navajo culture.

    D. Skills are needed to do business with the Navajo.
