Cortana, Alexa ,Siri ,These are names of robotic voices that are often programmed on electronic tablets. They also become default (默认) identities for people with speech disorders who rely on technology to communicate. Now some speech scientists are developing personalized voices to reflect the broader diversity of the people who use them. To do it, they are tapping into a vast network of volunteers who are donating their voices to share with people who can’t speak.
The effort to build an international “Human Voicebank” has attracted more than 17,000 volunteers from 110 countries, including Priyanka Pandya, a 16-year-old from Columbia, Md., who plans to spend her winter vacation recording a string of sentences into her computer “To be able to give somebody the gift of voice, I think that’s really, really powerful,” she said.
“Everyone has a voice,” said Rupal Patel, founder of VocaliD, the company that started the voicebank. “Even people who are unable to speak have sounds that are unique to them.” Her company designs personalized voices by recording the unique sounds of the user, and then mixing them with 6 to 10 hours of recordings from a voice donor, matched by age, gender and region. The company is developing voices now for its first 100 customers.
Also, people’s voices change. The company is looking for donors who are willing to record their voices, and then record them again a few years later, as they get older.
Some of the first customers say they are happy with the results, John A. Gregoire was one of the first customers to receive a personalized voice from Vocalid last December. The voice came eight years after he developed ALS (肌萎缩侧索硬化症) and more than six years have passed since his voice became unintelligible to everyone except his wife and youngest son. “Having a distinctive voice is like getting something back that was stolen.” John said.
1.What can we know about the voicebank?
A.It collects all kinds of voices.
B.It gains strong public support.
C.It helps to recognize special voices.
D.It offers people personalized voices free.
2.What does the example of John A. Gregoire stress?
A. Customers' desire for personalized voices.
B.VocaliD's efforts to develop personalized voices.
C.Customers'satisfaction with personalized voices.
D.VocaliD's success in designing personalized voices.
3.What does the underlined word “unintelligible” mean in the last paragraph?
A.Unclear. B.Soft.
C.Incomplete. D.Rough.
4.What is the main idea of the text?
A.Volunteers donate their voices to VocaliD.
B.Vocalic is devoted to building a voicebank.
C.The Human Voicebank wins fame among people with speech.
D.The Human Voicebank helps people with speech problems.

Robots performing tasks according to a predetermined 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.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 advances, it reacts to good quality videos.And it will react to even lower quality homemade 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 teach a robot how 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 socalled feedback (反馈意见); another is the introduction of language.
“I believe it will take quite some time before the robots are able to understand metaphorical (比喻性的) language，”he added.“But，” he said，“we don't need that to create a new world where the robots will be working for us.”
1.The underlined phrase “capitalize on” in Paragraph 2 probably can be replaced by ________.
A．take hold of B．make use of
C．keep track of D．catch sight of
2.Aloimonos probably agrees that at present the robot ________.
A．can not fully digest what it learns
B．can not make a simple salad
C．can follow homemade videos
D．can understand metaphorical language
3.Robots are taught to understand a video mainly because ________.
A．they can easily follow fixed programs
B．they are smart enough to learn cooking
C．cooking videos are more interesting to watch
D．predetermined instructions are not flexible
4.Which of the following might best serve as the title of the passage?
A．Robots Creating a New World
B．Robots Making Cooking Videos
C．Robots Learning to Cook by Watching Videos
D．Robots Performing Tasks by Following Instructions

Researchers at Cornell University are one step closer to building robots that are more like humans. This new method is one you might not expect. However, a soft robot muscle that "sweats" to regulate its temperature. "Sweating takes advantage of evaporated (蒸发)water loss to rapidly dissipate heat and can cool below the environmental temperature. So as is often the case, biology provided an excellent guide for us as engineers."
The fingerlike devices are 3D printed, water powered, and can be used to grab things. They are made of two soft chemical materials: a base layer of (CH3) 2 CH-C3H5 NO covered in a multihole layer of (C3H5 NO)n. When the fingers reach a temperature of 30°C (86°F), the base layer reacts by shrinking, squeezing the water through the top pores (毛孔)in the top layer. The drying up is so efficient that the surface temperature of the actuator can drop by 21°C in just 30 seconds. That's three times more efficient than in humans. When wind from a fan is thrown into the mix, they cool down around six times as fast. The evaporation also cooled the object held by the actuator hand.
"The best part of this artificial strategy is that the heat regulation is based on the material itself," said T. J. Wallin, co-lead author, a research scientist at Facebook Reality Labs. "We did not need to have sensors or other components to control the sweating rate. When the local temperature rose above the set point, the pores would simply open and close on their own. "
While the result is exciting, it is only a first step. The robot has its weaknesses. The sweat can make the robot hand slippery, so the team is examining textures to improve its grasp. When the sweating takes place, the robot's mobility is also blocked and needs to refill its water supply.
"I think that the future of making these more biologically similar materials and robots is going to rely on the material composition," said co-lead author Rob Shepherd, an associate professor of mechanical and engineering. "This brings up a point about the importance of research involving several different academic subjects or areas, where really no one group has all the answers. "
1.Which can best replace the underlined word "dissipate" in paragraph 1?
A.turn down B.put aside
C.drive away D.take in
2.What can control the heating performance of the robot?
A.Its artificial material. B.Its accurate sensor.
C.Its sensitive devices. D.Its working surroundings.
3.What does paragraph 4 mainly talk about?
A.The disadvantages of the robot.
B.The next step of the researchers.
C.The rules the robot has to follow.
D.The effect of the new development.
4.What can we infer from Shepherd's words?
A.The future of the robot is promising.
B.The similar materials are too difficult to develop.
C.Only working together can make the robot more successful.
D.The next step of his team is to search for suitable software.

Some African schools are adding programs that teach what officials are calling “soft skills” to students. Soft skills are personal qualities that help a person relate effectively to others. Officials say this kind of training can help students succeed in the job market and in life.
The training is being offered at the St. Bernadette Kamonyi Secondary School in Kigali, Rwanda. For weeks, its students have been visiting neighborhood businesses. The goal of these field trips is for the young people to learn what is necessary to secure a job.
For the secondary school students, this information is important. In a few months, they’ll complete their studies and try their best to find work. One of the Rwandan students is 22-year-old Aminadab Niyitegeka. He says he will look for any job available. He hopes that what he learns in his work readiness class will help. Traditionally, secondary schools in Africa have spent more time on subjects like mathematics and science, largely ignoring areas like public speaking and teamwork. But that is changing. Schools are exploring new teaching models to offer soft skills and professional training. It is part of an effort to perpare students to become better communicators, problem solvers and citizens(公民).
Rwanda has started a work readiness training program called Akazi Kanoze Access. It means “work well done” in Kinyarwanda, the official language of Rwanda. The program has trained more than 20,000 students to help make them more appealing to employers.
Emmanuel Ntagungira is a teacher and works as a trainer for Akazi Kanoze Access. He often visits employers who have given jobs to high schools. The employers are very happy because the graduates are ready to work. He says he hopes the program will help lower unemployment, which stands at over 13 percent nationwide. He also explains that the graduates have a healthy mindset and employers are satisfied with the job they’ve been doing.
1.Why do St. Bernadette Kamonyi Secondary School students visit neighborhood businesses?
A. To find some suitable jobs for them.
B. To explore new learning methods.
C. To help the neighbors with daily affairs.
D. To learn some skills to get a job.
2.What do secondary schools in Africa traditionally focus on?
A. Subjects like mathematics and science.
B. Public speaking and teamwork.
C. Communicating skills with employers.
D. New teaching models and skills.
3.What does Emmanuel Ntagungira think of the program?
A. Instructive. B. Beneficial. C. Persuasive. D. Controversial.
