A

Robots performing tasks according to a predetermined （预先设定的）set of

instructions are nothing new. But robots able to learn how to cook by watching videos

are a completely different approach, which is conducted by a group of researchers at

the University of Maryland.

If you have posted a video of your favorite recipe on the popular website

YouTube, chances are that it will be used by a robot. The University of Maryland's

professor Yiannis Aloimonos, leader of the group, said, " There exists a large amount

of video information on the Internet that our robots can capitalize on. "

" At present, the videos are fed electronically, " said research scientist Cornelia

Fermuller. " Originally, we took our own videos, our cameras looking at us doing the

cooking, " she explained. " And, as the robot advanced, it reacted to good quality

videos. And it will react to even lower quality home-made videos. "

So far, the robot named Julia can make a simple salad by breaking each task into

basic parts, such as grasping a spoon, bringing it to the bowl, stirring the salad and

observing the results.

But why is a robot taught to understand a video when it can easily follow a fixed

program? Aloimonos believes predetermined instructions lack flexibility. He thinks

one of the problems is how to make the robot understand and use what it learns during

a certain task-the so-called feedback （反馈）. " I believe it will take quite some time

before the robots are able to understand the metaphorical（隐喻的） language, " he

added. " But, " he said, " we don't need that to create a new world where the robots

will be working for us. "

【4】Which of the following might best serve as the title of the passage?

B

Recently a Beijing father sent in a question at an Internet forum（论坛）asking

what" PK" meant. " My family has been watching the 'Super Girl' singing competition

TV programme. My little daughter asked me what 'PK' meant, but I had no idea, "

explained the puzzled father.

To a lot of Chinese young people who have been playing games online, it is

impossible not to know this term. In such Internet games, " PK" is short for" Player

Kill" , in which two players fight until one ends the life of the other.

In the case of the" Super Girl" singing competition, " PK" was used to refer to

the stage where two singers have to compete with each other for only one chance to

go up in the competition ranking.

Like this father, Chinese teachers at high schools have also found their students'

compositions using Internet jargon which is difficult to understand. A high school 3/ 17 teacher from Tianjin asked her students to write compositions with simple language,

but they came up with a lot of Internet jargon that she didn't understand. For example,

" GG" means Ge Ge （Chinese pinyin for" brother" ）. " KPM" is short for KFC,

Pizza Hut and McDonald's.

Some specialists welcome Internet jargon as a new development in language. If

you do not even know what a Kong Long（dinosaur, referring to an ugly-looking

female） or a Qing Wa（frog, referring to an ugly-looking male）is, you will possibly

be regarded as a Cai Niao!

【5】By writing the article, the writer tries to .

A. explain some Internet language

B. suggest common Internet language

C. laugh at the Beijing father

D. draw our attention to Internet language

【6】What does the writer think about the term" PK" ?

A. Fathers can't know it.

B. The daughter should understand it.

C. Online game players may know it.

D. " Super Girl" shouldn't have used it.

【7】The examples of the Beijing father and the Tianjin teacher are used to show that

Internet jargon .

A. is used not only online

B. can be understood very well

C. is welcomed by all the people

D. causes trouble to our mother tongue

【8】What would be the best title for the passage?
