While the start of a new school year is ...

    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 human­like robot walking around the classroom. Instead, he is a computer­created 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 human­like behavior. He is designed to teach a special program about environmental­friendly 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 two­way exchange helps get the students' attention. More importantly, it allows the program developers to improve Bill's 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 attracts 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, this 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. Bill's future might be as a “personal tutor” providing kids with one­on­one help for different subjects and topics.

1.What is Bill?

A.A human­like robot.

B.A kind of computer game.

C.A computer recording tool.

D.A computer­created talking head.

2.How does the two­way exchange help the program developers?

A.It lets them correct students' mistakes.

B.It allows Bill to respond more quickly.

C.It helps them know how to improve Bill.

D.It helps them study students' body language.

3.What does the word “they” refer to (指的是)?

A.Kids. B.Older people.

C.Smart machines. D.Program developers.

4.What is Bill NOT good at doing?

A.Attracting students' attention.

B.Understanding students' body language.

C.Responding to students' questions.

D.Dealing with unexpected situations.

5.How might Bill be used in the future according to the last paragraph?

A.To work as human classroom teachers.

B.To encourage students' interest in computers.

C.To give students personal help with different subjects.

D.To watch over the behavior of the students in the classroom.

 

1.D 2.C 3.A 4.D 5.C 【解析】 本文是一篇说明文。主要介绍了一个叫Bill的机器人老师。 1. 细节理解题。题干意为:Bill是做什么的?根据文章第一段第四句“Instead, he is a computer­created head that appears, when needed, on students' computer or phone screens.”可知,他是一个电脑创作出的头像,需要时会出现在学生们的电脑或手机屏幕上。故选D。 2. 细节理解题。题干意为:双向交换是如何帮助程序员的? 根据文章第三段最后一句“More importantly, it allows the program developers to improve Bill's behavior and knowledge base when needed.”可知,更重要的是,这种方式使程序员在需要的时候对Bill的行为和知识库进行改造。故选C。 3. 代词指代题。题干意为:单词“they”指代的是什么? 根据下文“他们出生在电脑和智能手机的时代”,可以推断出这里的they指代的是孩子们。故选A。 4. 细节理解题。题干意为:Bill不擅长做什么?根据文章最后一段第三句“...even the smartest computer... all the unexpected situations...即使是最聪明的计算机程序也无法对教育工作者每天面对的所有意外情况做出预测和反应。”可知他最不擅长对未知情况做出预测和反应。故选D。 5. 细节理解题。题干意为:根据最后一段,Bill将来可能被如何使用?根据文章最后一段最后一句“Bill's future might be as a ‘personal tutor', providing kids with one­on­one help for different subjects and topics.”可知Bill今后可能成为 “私人家教”,为孩子们提供一对一的帮助。故选C。

    Many people love travelling to different countries, but if you plan to go abroad, you should know how to behave in different situations around the world.

Most travellers enjoy meeting new people, but sometimes you can be rude without saying anything. In Russia, you should never shake hands in a doorway, and if you're travelling in Thailand, never touch people's heads or point your feet at people. When the Japanese meet new people, they like giving business cards—but you should read the card carefully, not just put it in your pocket.

In most countries in Europe, people expect a lot of eye contact when you talk to them, but in many Asian countries, a lot of eye contact seems unfriendly. And in South America, people usually stand quite close to each other when they talk, but in countries like the USA, you need to give people more personal space. Also, it's rude to interrupt Japanese people while they are talking to you. You must wait until they finish before you start speaking.

In restaurants in China, you can leave a bit of food on your plate. It's OK to start smoking before other people finish eating, which you mustn't do in the UK. When in India, remember to eat with your right hand. Also avoid leaving empty bottles on the dinner table in Russia—that's bad luck.

When you're travelling in Asia, if someone invites you to his or her home, don't forget to take off your shoes when you arrive. And if you visit an Arab family's home, don't admire anything valuable because your host will feel he should give it to you as a present.

With so much to think about, it's not surprising that many people prefer going on holiday in their own countries—or you might just decide to stay at home!

1.Which of the following statements is TRUE?

A.We can admire anything valuable in an Arab family's home.

B.In China, people cannot smoke before other people finish eating.

C.In Russia, it's impolite to shake hands with people in a doorway.

D.In the USA, people usually stand quite close to each other when they talk.

2.What will the people in the USA feel when someone stand close to them when talking?

A.Unfriendly B.Friendly.

C.Happy. D.Polite.

3.What does the underlined word “interrupt” mean in Chinese?

A.跟随 B.打断 C.附和 D.强调

4.What is the correct order of the title from Paragraph 2 to Paragraph 5?

a. Eating out

b. In the home

c. Body language

d. Face to face communication

A.bcda B.dabc C.cdab D.abcd

5.What's the best title for the text?

A.Culture shock B.Table manners

C.Public rules D.Travelling plans
