     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 Milan 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 ceils. 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. Milan, 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 to update computer systems
B. help the disabled to recover
C. link the human brain with computers
D. control a person"s thoughts
2. How did Tavella operate the wheelchair in the laboratory?
A. By controlling his muscles.
B. By talking to the machine.
C. By using his mind
D. .By moving his hand.
3. Which of the following shows the path of the signals described in Paragraph 5?
A. scalp→computer→cap→wheelchair
B. computer→cap→scalp→wheelchair
C. cap→computer→scalp→wheelchair
D. scalp→cap→computer→wheelchair
4. 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. Robotic Vehicles Could Help to Cure Brain Injuries
D. BCI Could Mean More Freedom for the Disabled

阅读理解     Children always appreciate small gifts of money. Father, of course, provide a regular supply of
pocket-money, but uncles and aunts are always a source of extra income. With some children, small
sums _go a long way. If sixpences are not exchanged for sweets, they rattle for months inside the money-
box. Only very thrifty children manage to fill up a money-box. For most of them, sixpence is a small price
to pay for a satisfying bar of chocolate.
      My nephew, George, has a money-box but it is always empty. Very few of the sixpences I have given to him found their way there. I gave him sixpence yesterday and advised him to save it. Instead, he bought himself sixpence worth of trouble. On his way to the sweet shop, he dropped his sixpence and it rolled
along the pavement and then disappeared down a drain. George took off his jacket, rolled up his sleeves
and pushed his right arm through the drain cover. However, he couldn"t find his sixpence anywhere, and
what"s more, he couldn"t get his arm out. A crowd of people gathered round him and a lady rubbed his arm with soap and butter, but George was firmly stuck. The fire-brigade was called and two firemen freed
George using a special of greese . George was not too upset by his sixpence because the lady who owns
the sweet shop heard about his trouble and rewarded him with a large box of chocolate.

阅读理解                                 Students and Technology in the Classroom
     I love my Blackberry-it"s my little connection to the larger world that can go anywhere with me. I also
love my laptop computer, as it holds all of my writing and thought. Despite this love of technology, I know that there are times when I need to move away from these devices(设备)and truly communicate with
others.
     On occasion, I teach a course called History Matters for a group of higher education managers. My
goals for the class include a full discussion of historical themes and ideas. Because I want students to
thoroughly study the material and exchange their ideas with each other in the classroom. I have a rule -no
laptops, iPads, phones, etc. When students were told my rule in advance of the class, some of them were
not happy.
     Most students assume that my reasons for this rule include unpleasant experiences in the past with
students misusing technology. There"s a bit of truth to that. Some students assume that I am anti-technology. There"s no truth in that at all. I love technology and try to keep up with it so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students
to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently
and to make connections between the course the material and the class discussion.
     I"ve been teaching my history class in this way for many years and the educations reflect student
satisfaction with the environment that I create .Students realize that with deep conversation and challenge,
they learn at a level that helps them keep the course material beyond the classroom.
     I"m not saying that I won"t ever change my mind about technology use in my history class, but until I
hear a really good reason for the change. I"m sticking to my plan. A few hours of technology-free dialogue
is just too sweet to give up.1. Some of the students in the history class were unhappy with____.A. the course material
B. others" misuse of technology
C. discussion topics
D. the author"s class regulations2. The underlined word "engage "in Para.4 probably means ____.A. explore
B. accept
C. change
D. reject 3. According to the author ,the use of technology in the classroom may ____.A. keep students from doing independent thinking
B. encourage students to have in-depth conversations
C. help students to better understand complex themes
D. affect students" concentration on course evaluation4. It can be inferred from the last paragraph that the author ____A. is quite stubborn
B. will give up teaching history
C. will change his teaching plan soon
D. values technology-free dialogues in his class

     The zebra belongs to the horse family. One of nature"s great mysteries is why the zebra has stripes.
One theory is that the stripes help the zebra cool down. On hot days the black stripes get a lot hotter than
the white area of the zebra and under the black stripes there are special layers of fat for protection. Hot
air then rises off the black stripes, forcing colder air down around the white areas, cooling the zebra
down. This, however, is just a theory. The stripes can also confuse predators (食肉动物) when zebras
stay with other animals in great numbers.
     Zebras have excellent hearing and eyesight and can run at a speed of up to 35 miles per hour
(56 kilometers per hour). They also have a powerful kick that can cause serious injury to a predator, like
a lion, or an African wild dog. Usually the lead male of the herd stays at the back of the group to defend
against predators if necessary, while the females and youngsters run from danger.
     Zebras are herbivores and feed mostly on grasses, although they also might eat the leaves and stems (茎) of bushes a bit. They eat grasses for many hours each day, using their strong teeth. Spending so
much time chewing wears the zebra"s teeth down, so their teeth keep growing all their lives. As the dry
season arrives and the grasses die back, zebra herds travel to find more food and water holes for drinking. Most zebras have no specific territories. They travel from place to place, never staying in one area very
long.1. What can be inferred from the first paragraph?A. There are different opinions about why the zebra has stripes.
B. The black stripes help the zebra live through cold days.
