AGNES stands for "Age Gain Now Empathy System" and was designed by researchers at MIT's AgeLab to let you know what it feels like--physically--to be 75 years old."The business of old age demands new tools,"said Joseph Coughlin,director of the AgeLab."While focus groups and observations and surveys can help you understand what the older consumer needs and wants,young marketers never get that'Ah ha!'moment of having difficulty opening a jar, or getting in and out of a car.That's what AGNES provides." Coughlin and his team carefully adjusted the suit to make the wearer just as uncomfortable as an old person who has spent a lifetime eating poorly and not doing much exercise.Special shoes provide a feeling of imbalance,while braces on the knees and elbows limit joint mobility.Gloves give the feeling of decreased strength and mobility in the hands and wrists,and earplugs make it difficult to hear high--pitched sounds and soft tones.A helmet with straps attached to it presses the spine ,and more straps attached to the shoes decrease hamstring flexibility, and shortens the wearer's step. AGNES has been used most recently by a group of students working on a design of .By wearing the suit they could see for themselves what design and materials would make the most sense for a physically limited older person.Coughlin said the suit has also been used by clothing companies,car companies and retail goods companies to help them understand the limitations of an older consumer. "AGNES is not the destiny of everybody," he said."She is a badly behaved lady who didn't eat and exercise very well.A secondary benefit we've found with AGNES is that it has become a powerful tool to get younger people to invest in their long-term health." Question: Which may be a fact resulting from the "secondary benefit" of AGNES? - Young people respect old people. - Old-age business improves their service - Old people eat and exercise well. - Young people eat and exercise well.
Young people eat and exercise well.

Applied Physics laboratory ( APL) in Laurel , Maryland have designed a new human-like robot, Its name is Robo Sally. The machine can be controlled from a distance and can he used to do work that is dangerous for human beings. Roho Sally has two long arms with human-like hands. She can use her fingers to pick up small objects .examine them in detail and do most things that human hands can do Each finger contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, . Mike McLoughlin is the main investigator for the Applied Physics Laboratory's Prosthetics Program. "The purpose of that program is to develop prosthetic arms that have all the capability of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. " It was a difficult job. Mr. McLoughlin says the device had to have many small motors to. have the ability to do what a human hand does; It also needs to have human-like strength. The thumb was especially difficult because it permits the hand .to hold objects. And everything had. to fit into a space about the size of a human hand. The next problem .he says .was to figure out how to control the artificial hand. " So we had to figure out how to make the connection between the brain and this arm. For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses. The glasses permit the operator to see the robot's hands .even though they are far away. Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is not ready for everyday application .but he predicts that within five years... Question: What can we learn ahout the prosthetic arms according to the passage? - They are expected to function as well as natural ones. - They have many large motors controlled by robots. - They have human-like strength to control the robot. - They are connected with human brains.
They are expected to function as well as natural ones.

Read the following article and select the best answer. Article: The area south of the Thames at Greenwich has a long history. Throughout time different buildings have been constructed on the same site. The Palace of Placentia, an English Royal Palace built in 1447, no longer exists apart from a few remains under the present buildings. The grand buildings on the South Bank of the Thames at Greenwich were designed by Sir Christopher Wren, most famous for St. Paul's Cathedral. The buildings were finally completed in 1745, although some parts started to be used as early as 1705. They're now part of a university -- having served as a naval hospital and a naval college and the setting for several cinemas. But the buildings stand on a site which has a much longer history, of which now only a part remains that is below the ground. For nearly two hundred years, from around 1450 to 1650, Greenwich was one of the main royal palaces of England. Some of the most famous English rulers, such as Henry VIII and Elizabeth I, not only lived there, but also were born there. Henry VIII put an armory there, and there were also gardens, a great fountain and a mass of buildings. The Palace was also in a strategic location, because at the time either side of Greenwich on the Thames were important Royal Dockyards . Eventually, though, the Palace fell into disrepair. In 1664, the King at the time, Charles II, decided to replace it with completely new buildings in a modern style. Only a cellar from the former Royal Palace now remains, under one of the new buildings. Its red brick, typical of the 16th century, contrasts sharply with the white stone above it. Would you like to join us to have a good view of Greenwich? Question: According to the passage, when did the Palace of Placentia disappear from the ground? - In the late 1400s. - In the early 1600s. - In the late 1600s. - In the early 1700s.
In the late 1600s.
