初中英语文中细节试题

While the start of a new school year is always exciting， this year was even more so for some students at White Cloud Primary School． They became the world's first kids to be taught by an electronic teacher． This electronic teacher is not a human﹣like robot walking around the classroom Instead， he is a computer﹣created head that appears， when needed， on students computer or phone screens． His name is Bill．

    Created by technology company Smart Machines， Bill is able to show human﹣like behavior． He is designed to teach a special program about environmental﹣friendly power created by the sun and wind． This program， started in 2005， used to be taught by human teachers．

    Just like human teachers， Bill is able to immediately respond to the students' questions and opinions about the topic． Thanks to computer cameras， he is also able to see and react to students physical actions． For example， if a student smiles at Bill， he responds by smiling back． This two﹣way exchange helps get the students' attention． More importantly， it allows the program developers to improve Bills behavior and knowledge base when needed．

    The program has been a great success， according to Smart Machines spokesman Robert Frost Frost says， "What is interesting to me is the children's reaction to Bill． He really captures their attention． "Frost thinks kids don't find the experience of being taught by smart machines as strange as older people because they have grown up in a time of computers and smart phones．

    It is doubtful， however， that human educators will lose their jobs to Bill any time soon． For one，his talking head's knowledge base is not large． More importantly， even the smartest computer programs can't guess and react to all the unexpected situations that educators face daily． Bills future might be as a"personal tutor"， providing kids with one﹣on﹣one help for different subjects and topics．

（1）What is Bill？　　

A． A human﹣like robot

When Justin Tong was a child， other kids felt sorry for him． His parents always had him doing lots of housework such as carrying out the rubbish and sending newspapers． But when he grew up， he was better off than his childhood friends and lived a happier and healthier life．

    These are the finding of a 40﹣year study that followed the lives of 456 children in London． It showed that the children who had worked hard in childhood had a richer and a happier future． "Children who worked in the home or community gained competence（能力） and came to feel they were worthwhile members of society，" said Daniel Brown， the psychologist（心理学家） who made the discovery． "And because they felt good about themselves， others felt good about them．"

    Brown's study followed these children in great detail． Interviews were repeated at ages 25， 31 and 47． Under Brown， the researchers compared the children's mental﹣health scores with their childhood﹣activity scores． Points were awarded for part﹣time jobs， housework， effort in school， and ability to deal with problems．

    Working at any age is important． Childhood activities help a child develop responsibility， independence， confidence and competence ﹣ the underpinnings （基础） of emotional health． They also help him understand that people must cooperate and work toward common goals． The most competent adults are those who know how to do this．Yet work isn't everything． As Tolstoy once said， "One can live magnificently in this world if one knows how to work and how to love， to work for the person one loves and to love one's work．"

（1）What do we know about Justin Tong？　　

A．He enjoyed a happy life．

B．He felt sorry for the other kids．

C．He always sold newspapers．

D．He seldom collected rubbish．

（2）Who will probably succeed in the future according to Paragraph 2？　　

A．Children who enjoy happier and richer lives．

B．Children who work in the home or community．

C．Children who take part in Daniel Brown's study．

D．Children who feel good about people around them．

（3）How did Brown follow the children in his study？　　

A．By giving housework and praise．

B．By interviewing and giving scores．

C．By setting goals and showing love．

D．By solving problems and testing them．

（4）What's the purpose of the passage？　　

A．To talk about an interesting study．

B．To introduce Justin Tong's success．

C．To tell us about childhood activities．

D．To encourage children to work hard．

Momofuku Ando invented instant noodles in Japan in 1958.Few people know that instant noodles play an important role in hunger and disaster （灾害） relief.It's well﹣known that they are regarded as junk food，but they are a real "hunger killer".According to an online news report，the fat in instant noodles that is mixed with the delicious soup keeps one feeling full for longer.And that helps explain why"ramen"，as they are called in Japanese，have become a staple on the world's food aid （援助） lists.

What would you do if you had trouble seeing clearly？You would probably go to an eye doctor who might give you glasses.For many people around the world，however，such a way isn't that simple.

The World Health Organization reports that glasses can help one billion people in the world.Yet places like Ghana have only one eye doctor every 8 million people. Thismakes glasses almost impossible to get.Joshua Silver，a teacher at Oxford University，however，may have solved the problem.

Mr.Silver has developed liquid（液体）﹣filled glasses that users can adjust（调整） by themselves without seeing a doctor!The lenses（镜片） are filled with oil.Using a dial on the glasses，the user changes the amount of oil.This changes the strength（度数） of the lens.After the user finds the right strength，he then fixes the lens.

Results show that among those who have tried the glasses，around 80% are satisfied.Mr.Silver's goal is for everyone who still needs glasses to have such glasses as soon as possible.With a little more effort，Mr.Silver thinks that his goal might be achieved in the near future.
