Not even Dan Brown and his Da Vinci code—breakers(密码破译者)dared deal with the mystery of Mona Lisa,s smile.But Nicu Sebe,a computer expert the University of Amsterdam,the Netherlands,did.He used’emotion recognition’software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厌烦的)(9 per cent).
Faces show emotions. Psychology,computer science,and engineering researchers are joining forces to teach machines to read expressions.If they succeed,your computer may one day“read”your mood.Machines equipped with emotional skills could also be used in teaching,gaming,mind-reading,etc.
“Mind Reader”,a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Tech’nology)in the US, uses input from a video camera to do real—time analysis of facial expressions. It reports on whether you seem“interested”or“agreeable”or if you’re“confused”.The system can help people recognize others’emotions.Picard says this means we could teach a machine to be as sensitive as a human.In fact,a machine can be even smarter than people since it can tell if a person is lying or just“performing”by analyzing one’s facial movements.
Jeffrey Cohn,a psychologist at the University of Pittsburgh,uses the Facial Action Coding System to recognize human emotions.The system sorts more than 40 action units(AUs)of the face to tell people’s real emotions.He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else.But Cohn saw no real sadness in the woman’s face.
Sadness is a group of AUs that is difficult to do at the same time.You have to pull down the woman’s of your lips while bringing your eyebrows together and raising them.What the woman did was raise her cheeks to make a lip cud(撇嘴)。Her brows stayed smooth.
64.The best title of this passage is“ ________ ”.
A.The emotion on your face                    B.Look at your face
C.Your face tells a story                          D.Telling a lie
65.The missing sentence“This means,even though your mouth lice,your face doesn’t,and the machine will know it all. ”should be put at the end of ___________.
A.Paragraph 2   B.Paragraph 3      C.Paragraph 4     D.Paragraph 5
66.How many facial emotion analyses are mentioned in this passage?
A.Four.               B.Three.              C.Two.         D.One
67.The underlined word“it”refers to________.
A.MIT                                 B.the video camera
C.one’s face emotion            D.the real—time analysis

Today, we have a world economy. Canadian businesses and workers must compete with businesses and workers in other countries.
Every year, more Canadian factories are closing or moving。 They cannot compete with factories in countries where wages(工资) are low. In the future, there will be fewer jobs for factory workers in Canada.
Many Canadian businesses are trying to spend less money. For example, they are hiring more part-time workers and more temporary(临时的) workers. They are employing fewer permanent(永久的)full-time workers. More services, fewer goods. Canada’s economy is changing. Businesses are making fewer goods(for example: shoes and radios). But Canadian businesses are providing more services to people.
In the future, there will be more jobs for people who provide services. For example: sales people, waiters and waitresses, home health care workers, bakers and cooks.
There will be fewer jobs for other kinds of workers(for example: farmers , miners , fishermen, forestry workers and factory workers).Many new jobs will be in small businesses with 20 or 30 employees. Technology machines are changing the way people work. Business are using many machines (for example: computers and robots).
Businesses will need fewer workers. And some jobs will disappear. Many grown-ups will have to go back to school or train for new jobs. Workers will not stay in the same job for their lifetime. The population of Canada is changing.
Today, many Canadians are in their 30s and 40s. They need goods and services. As they get older, they will need different goods and services.
Canadians come from many cultures. They have different customs and religions. Employers and workers must learn to work with many different people.
44. World economy means_________ to Canada.
A. closing and moving           B. competition
C. low wages                   D. improvement
45. Which of the following will be fewer in the future in Canada?
A. Restaurants       B. Shops        C. Doctors  D. Farmers
46. Businesses will need fewer workers because_____________.
A.  the owners can’t afford them
B. some jobs will disappear
C. machines will take the place of workers in many ways

Members of Parliament (MPs) warned that the privacy(隐藏)of thousands of mobile phone users is in danger today because of Google's new tracking system. In a motion(提案),they also warned that the system offers live tracking of mobiles through a website and called on Google to examine the service.
The Latitude system can find where a user is . This is then broadcasted live to Google's website. Once the service is activated , the position of a person's phone appears as a blue dot on a map on the screen of whoever is allowed to monitor(监控)them . The Latitude feature is being developed by Google as a "fun" way to "keep tabs on someone special", More than a million users around the world have already signed up to the service, Google claims .
However, concerns have been raised about the system. MPs have written to Google demanding extra security(安全) safeguards on the service。
Mr. Brake , one of the MPs who raised the motion, said , "In Britain, we have a tradition of fighting for our freedom. With this new system we face a threat to it . I demand MPs to support this motion and encourage the Government to take action to ensure that Latitude does not represent a threat to our privacy. or our freedom could be in danger."
Google today insisted there was no threat to privacy .It said it was up to users to decide whether to make their location visible to other people and to decide who could monitor their position .The service was designed to help people keep in touch .
However , human rights watchdog Privacy International analyzed the service and claimed it was open to abuse(滥用). Its report claimed employers could supply employees with phones already set up to use the service without their knowledge, or that users could simply sign up their partner's or child's mobile phone without telling them .

A.they have raised a motion
B.they have required Google to examine the service
C.they hope that the Government will take some measures
D.they are trying to get help from other countries

C
Instead of hitting the beach, fourteen high school students traded swimming suits for lab coats last summer and turned their attention to scientific experiments.
The High School Research Program offers high school students guidance with researchers in Texas A&M’s College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department of Rangeland Ecology and Management, directs this four-week summer program designed to increase understanding of research and its career potential(潜能)。
Several considerations go into selecting students, including grades, school involvement and interest in science and agriculture. And many students come from poorer school districts, Funkhouser says, “This is their chance to learn techniques and do experiments they never would have a chance to do in high school.”
Warner Ervin of Houston is interested in animal science and learned how to tell male from female mosquitoes(蚊子).His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school students.
The agricultural research at A&M differs from stereotypes. It’s “molecular(分子)science on the cutting edge,” Funkhouser says. The program broadened students’ knowledge. Victor Garcia of Rio Grande City hopes to become a biology teacher and says he learned a lot about chemistry from the program.
At the end of the program, the students presented papers on their research. They’re also paid $600 for their work----another way this program differs from others, which often charge a fee.
Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and plowing and that research can open many doors.
63.The research program is chiefly designed for           .
A. high school advisers from Houston
B. college students majoring in agriculture
C. high school students from different places
D. researchers at the College of Agriculture and Life Sciences

C. found the program useful to their future
D. showed much interest in their high school experiments
65.When the program was over, the students          .
A. entered that college        B. wrote research reports
C. paid for their research      D. found way to make money
66.The underlined expression “on the cutting edge” in paragraph 5 means “on the most________
position”.
