Losing an arm means losing the ability to grab, as well as losing the sense of touch. Scientists have been working on mind-controlled prostheses (义肢) and have successfully built a few to help patients regain their ability to grab. But restoring the sense of touch has been quite a challenge – until now.
Seven years ago, a group of Swedish scientists created a new type of prostheses, which has since then been tried out on three patients to see how they perform in people’s daily lives. The study result was recently published in the New England Journal of Medicine.
According to the study, this is the first time that people who have had an arm amputated (截肢) can experience sensations of touch in mind-controlled arm prostheses.
The new product is named “neuromusculoskeletal” prosthesis. As the name indicates, the prosthesis is connected directly to a user’s nerves, muscles and skeleton. The sensation of touch becomes possible by stimulating nerves that used to be connected to the biological hand before the amputation.
When a patient grabs an object, for example, force sensors planted in the prosthetic thumb would measure contact and pressure. The collected information would then be transmitted to the patient’s nerves that lead to the brain. In this way, the patient can “feel” the characteristics of the object being touched and perceive (感知) its pressure against the prosthetic hand, which can be crucial when handling delicate objects – an egg, for example.
“The ability of the patients to discern (觉察) smaller changes in the intensity of sensations has improved,” Max Ortiz Catalan, Associate Professor at Chalmers University of Technology, Sweden, who is the leader of the study, told Science Daily.
According to Catalan, the new study has demonstrated that their prosthesis is qualified as a “clinically viable replacement for a lost arm”.
“The sensors are not the obstacle for restoring sensation,” Catalan added. “The challenge is creating neural interfaces (接口) that can seamlessly (无缝地) transmit large amounts of artificially collected information to the nervous system, in a way that the user can experience sensations naturally and effortlessly.” And they did it.
With the development of prosthesis technology, people who suffer from limb loss will have a greater chance of getting their normal lives back.
1.Neuromusculoskeletal prosthesis’ unique advantage is helping people with arm amputations to _____ .
A.carry heavy objects again B.regain the ability to grab objects
C.move their prostheses as they wish D.experience the sense of touch again
2.The new prosthesis is connected directly to __________.
① user’s nerves ② user’s brains ③ user’s muscles ④ user’s skeleton
A.① ② ③ B.① ③ ④ C.② ③ ④ D.① ② ④
3.How do the new prostheses work?
A.They collect information about objects and process it.
B.They stimulate the cut nerves to restore the sense of touch.
C.They measure the size of objects and send the information.
D.They detect the material of objects and send the information.
4.What can patients perceive with the new prosthesis?
A.The intensity of an object. B.The structure of an object.
C.The pressure from an object. D.The changes inside an object.
5.What is the difficulty in developing the new technology?
A.Measuring the pressure of objects. B.Connecting the sensors to nerves.
C.Creating good neural interfaces. D.Building responsive sensors.
6.What’s the author’s attitude towards the prospect of prosthesis technology?

From bankers to factory staff, employees in the west face the bleak prospect of losing their jobs as a global recession starts to bite. For colleagues in the East the pain is more likely to come through a pay cut.
Human resource experts say cultural differences explain why Asian firms try harder to keep jobs in difficult times, which will stop unemployment and may help keep Asian economies afloat at a time of slowing exports.
The East Asian attitude may also make it easier for firms to recover quickly from the economic downturn since they will not need to rehire or train new staff, leaving some experts predicting Western shift to Eastern flexibility.
“In the Confucian attitude, the right thing to do is to share the burden. There is the sense of collective responsibility whereas in the west, it’s more about the individual survival,” said Michael Benotlel, associate professor of organizational behavior at Singapore Management University.
Steven Pang, Asian Regional director for Aquent, a headhunting firm, said in many East Asian companies there was an responsibility “ to take care of the members of the family and go through the pain together” even if that meant causing losses.
Us firms from General Motors to Goldman Sachs plan to lay off workers by the thousands. But at the Asian units of Western multinationals, jobs cuts will probably be less severe.
Japan’s jobless rate was 4 percent in September, up from 3.8 percent in January, while Hong Kong’s was flat at 3.4 percent. But US unemployment is expected to have jumped to 6.3 percent last month from below 5 percent in January.
Experts say that while there are noticeable differences in labor practices in East
and West, the gap will narrow as more firms become more multinational and competition forces firms to adopt the best practices of rivals from abroad.

One of the worst feelings you have as a professional athlete is the feeling after losing a game to a team that you should have beaten. That happened last night against the lowly Boston Celtics. They had only won 13 games the whole year and were really struggling. We had just come off a very good win against the Orlando Magic on the road and were feeling good about ourselves.
The day did not start out good for us when we learned that T-Mac was going to miss the game with the flu. When you lose your best players (Yao, T-Mac) everyone must play a little harder and do a little bit more on the floor. We inserted Bonzi Wells into the lineup (he was the only one to have a good game for us), in place of T-Mac.
It was a nasty game. We are usually one of the best three point shooting teams in the NBA and we only made 1 of 22 three point shots! I have never seen that happen. Never! Rafer Alston, Luther Head, and me combined to shoot 5 of 33 from the field. Ouch! You aren't going to win too many games like that. Even as poorly as we shot the ball, we STILL had a chance to win the game in the fourth quarter but failed to make the winning plays that you must make to leave the floor victorious.
In the locker room after the game, everybody felt terrible. When we play a bad game, we feel that we let our teammates down. There is a bad feeling in the pit of your stomach when you leave the gym and you just want to go home and not talk to anyone. It is a terrible feeling, but it is a feeling that makes you want to try harder and do better the next time.
I'll talk to you guys later.
Shane
1.What is the passage mainly about?
A. To blame the team for losing the game.
B. To tell the readers about the feeling after losing the game
C. To explain why they played poorly in the game.
D. To blame Yao Ming and T—Mac for being absent from the game.
2. What can the readers learn from the text?
A. The Boston Celtics is one of the top teams in NBA.
B. The Boston Celtics had a big win over the writer’s team.
C. Every one of the team played poorly with no energy.
D. Bonzi Wells starts in the game with T-Mac out.
3. How do you think the writer might describe his performance that night?
A. Tough B. Relaxing C. Terrible D. Efficient
4.The text most probably comes from the writer’s _________ .
A. blog B. telephone message C. note D. interview
