TOKYO—A child-like robot that combines the roles of nurse, companion and security guard is to go on the market to help the growing ranks of elderly Japanese with no one to look after them.
The “Wakamaru” robot can walk around a house 24 hours a day, warning family, hospitals and security firms if it perceives (notices) a problem. It will, for example, call relatives if the owner fails to get out of the bath.
Cameras implanted in the “eye-brows” of the robot enable it to “see” as it walks around an apartment. The images can be sent to the latest cellphones, which display the pictures.
Mitsubishi Heavy Industries, which developed Wakamaru, plans to start selling the metre-high robots by April, 2005, for about ＄15,000 Cdn.
Wakamaru, which speaks with either the voice of a boy or girl, is also designed to provide companionship, greeting its “papa” when he comes home.
It is the first household robot able to hold simple conversations, based on a vocabulary of around 10,000 words. It cannot only speak but can understand answers and react accordingly.
It will ask “Are you all right ?” if its owner does not move for some time. If the answer is no, or there is no answer, it will telephone preset numbers, transmitting images and functioning as a speakerphone.
Wakamaru will inform a security firm if there is a loud bang or if an unknown person enters the house while the owner is out or asleep. It can recognize up to 10 faces.
But like most robots it cannot climb stairs.
It can be set to remind forgetful people when it is time to take medicine, eat and sleep.
Mitsubishi adapted Wakamaru from robots it already makes to go around nuclear power facilities. The idea to use the technology in the home came from a company employee.
The project chief said :“Looking at the ageing of society and the falling birth rate we decide that this could work as a business. We want to offer Wakamaru as a product that helps society.”
The technology has gained nation-wide publicity in Japan among increasing concern over how to look after the ever-growing number of old people. The life expectancy of Japanese women has shot up to almost 85, the highest in the world.
At the same time, extended families are being replaced by nuclear families. This has left many Japanese anxious about their elderly parents, whom they rarely see because of their long hours at the office.
55.which of the following is true about the Robot？
A.it is used in some nuclear power facilities
B.ic can recognize asmany as 10 faces
C.it can go up and down the stairs easily
Dit cannot speak but can understand answers。

Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.
An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.
However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.
In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents - today’s grandparents - would have called their children more often if the means and cost of doing so had not been a barrier.
Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.
Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyondthe role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.The surveys inform us of ______.
| A．the development of technology |
| B．the changes of adult children’s behavior |
| C．the parents’ over-protection of their college children |
| D．the means and expenses of students’ communication |
The writer believes that ______.
| A．parents today are more protective than those in the past |
| B．the disadvantages of new technology outweigh its advantages |
| C．technology explains greater parental involvement with their children |
| D．parents’ changed attitudes lead to college children’s delayed independence |
What is the best title for the passage?
| A．Technology or Attitude |
| B．Dependence or Independence |
| C．Family Influence or Social Changes |
| D．College Management or Communication Advancement |

Life in the Clear
Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”
And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.
The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.
But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending or stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.
To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.
Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread themselves over it .
Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.According to Paragraph 1, transparent animals_______.
| A．stay in groups | B．can be easily damaged |
| C．appear only in deep ocean | D．are beautiful creatures |
The underlined word “dead” in Paragraph 3 means__________.
| A．silently | B．gradually |
| C．regularly | D．completely |
One way for an animal to become transparent is to ________.
| A．change the direction of light travel |
| B．gather materials to scatter light. |
| C．avoid the absorption of light |
| D．grow bigger to stop light. |
The last paragraph tells us that larger transparent animals________.
| A．move more slowly in deep water |
| B．stay see-through even after death |
| C．produce more tissues for their survival |
| D．take effective action to reduce light spreading |

The Boy Made It!
One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn’t have food, water, a phone, or other supplies. He was getting colder by the minute.
Nicholas had no idea where he was. He tried not to panic. He thought about all the survival shows he had watched on TV. It was time to put the tips he had learned to use.
He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter form the freezing wind and snow. If he didn’t, his body temperature would get very low, which could quickly kill him.
Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.
By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn’t lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could- he huddled(蜷缩) in his cave and slept.
The next day, Nicholas went out to look for help, but he couldn’t find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.
Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls’ survival show. Man vs. Wild. That’s where he learned the tips that saved his life, In each episode(一期节目)of Man vs. Wild, Grylls is abandoned in a wild area and has to find his way out.
When Grylls heard about Nicholas’ amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.What happened to Nicholas one Sunday afternoon?
| A．He got lost. | B．He broke his skis. |
| C．He hurt his eyes | D．He caught a cold |
How did Nicholas keep himself warm?
| A．He found a shelter. | B．He lighted some branches. |

On Tuesday, Nicholas _____.
| A．returned to his shelter safely |
| B．was saved by a searcher |
| C．got stuck in the snow |
| D．staved where he was |
Nicholas left Grylls a very deep impression because he _____.
| A．did the right things in the dangerous situation |
| B．watched Grylls’ TV program regularly |
| C．created some tips for survival |
| D．was very hard-working |
A rapidly advancing contemporary science that is highly dependent on new tools is Earth system science. Earth system science involves observation and measurements on the Earth at all scales from the largest to the smallest. The huge amounts of data that are gathered come from many different locations and require special techniques for handling data. Important new tools that facilitate Earth system science include satellite remote sensing, small deep-sea submarines, and geographic information systems.
More than any other way of gathering evidence, satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts.
Earth system science was born from the realization of that interdependence. Satellite remote sensing makes possible observations at large scales, and in many cases, measurements of factors that could not otherwise be measured. For example, the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing, as are changes in deserts, forests, and farmlands around the world. Such measurements can be used in many areas of specialization besides Earth system science. Archaeology, for example, has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert.
New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system. Small deep-sea submarines allow scientists to travel to the depths of the ocean. There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat, sasses, and mineral-rich water.
Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system. Computer-based software programs known as geographic information systems, or GIS, allow a large number of data points to be stored along with their locations. These can be used to produce maps and to compare different sets of information gathered at different times. For example, satellite remote sensing images of a forest can be converted to represent stages in the forest's growth. Two such images, made at different times can be overlaid and compared, and the changes that have taken place can be represented in a new image.The word "facilitate" in Paragraph I is closest in meaning to ________.
| A．enable | B．require | C．organize | D．examine |
The author of the passage mentions that satellite observations are especially effective in ________.
| A．conducting scientific studies of life on the ocean floor |
| B．predicting future climate changes |
| C．providing data to determine Earth's age |

According to the passage, satellite observations of the Arabian Desert allow archaeologists to know ________.
| A．indications of ancient routes |
| B．evidence of former lakes |
| C．traces of early farms |
| D．remains of ancient forests |
What is the main idea of the passage?
| A．special techniques are needed to classify the huge amounts of data about Earth. |
| B．New tools provide information about Earth that was once impossible to obtain. |
| C．Advances in Earth system science have resolved many environmental problems. |
| D．Satellite remote sensing can show changes between two images taken years apart. |
