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。

56.the purpose of this passage is

A.the robot can dial proper numbers for help

B.the nuclear families have left many elderly Japanese anxious

C.the robot has given the Japanese a chance to live longer。

D.the robot is likely to have a promising market

58．What is the best title of this passage ?

D. Japanese Robot and the Ageing Society

Chinese, unlike many other languages, has a large family of dialects and written forms. Spoken Chinese is specially complex with more than five recognized dialect groups, even the written language with two recognized characters.

The written forms of Chinese include a traditional system of characters and a simplified one. The simplified version of characters came into use in 1949.

Traditional Chinese characters are still widely used throughout Asia and among Chinese people around the world, while the simplified characters are only found in the People’s Republic of China.

It is usually accepted that there are five major dialect groups within the Chinese language group. These are Mandarin, Wu, Min, Cantonese and Hakka.

Mandarin is the official language on the Chinese mainland and Chinese Taiwan. It  is also one of the four official languages of Singapore.

Wu is spoken around the lower Yangtze River and its tributaies(支流). Shanghai is a well-known dialect of Wu.

Min is commonly spoken by people in Taiwan, Fujian and Hainan. Cantonese is mainly spoken in the province of Guangdong. Cantonese is also spoken in many parts of the Chinese Diaspra(移居地), particularly HongKong and overseas Chinese settlements in the United States, Europe and Southeast Asia. Hakka is the least well-known dialect group inside China compared to the above four. Most of the Hakka dialect group is scattered(散居) throughout southeastern China in Guangxi Province. Historically, the Hakka people were northerners who moved south over several hundred years. Their name Hakka means “guest” indicaing their immigrant(移民) status in the southern areas to which they moved.
