Robots can’t completely ________ humans though they are very clever.A.take the place o

For years, the U. S. has experienced a shortage of registered nurses. The Bureau of Labor Statistics projects that while the number of nurses will increase by 19 percent by 2022, demand will grow faster than supply, and that there will be over one million unfilled nursing jobs by then.
So what's the solution？ Robots.
Japan is ahead of the curve when it comes to this trend. Toyohashi University of Technology has developed Terapio, a robotic medical cart that can make hospital rounds, deliver medications and other items, and retrieve records. It follows a specific individual, such as a doctor or nurse, who can use it to record and access patient data. This type of robot will likely be one of the first to be implemented in hospitals because it has fairly minimal patient contact.
Robots capable of social engagement help with loneliness as well as cognitive functioning, but the robot itself doesn't have to engage directly—it can serve as an intermediary for human communication. Telepresence robots such as MantaroBot, Vgo, and Giraff can be controlled through a computer, smartphone, or tablet, allowing family members or doctors to remotely monitor patients or Skype them, often via a screen where the robot's ' face' would be. If you can't get to the nursing home to visit grandma, you can use a telepresence robot to hang out with her. A 2016 study found that users had a "consistently positive attitude" about the Giraff robot's ability to enhance communication and decrease feelings of loneliness.
A robot's appearance affects its ability to successfully interact with humans, which is why the RIKEN-TRI Collaboration Center for Human-Interactive Robot Research decided to develop a robotic nurse that looks like a huge teddy bear. RIBA (Robot for Interactive Body Assistance), also known as ‘Robear', can help patients into and out of wheelchairs and beds with its strong arms.
On the less cute and more scary side there is Actroid F, which is so human-like that some patients may not know the difference. This conversational robot companion has cameras in its eyes, which allow it to track patients and use appropriate facial expressions and body language in its interactions. During a month- long hospital trial, researchers asked 70 patients how they felt being around the robot and "only three or four said they didn't like having it around."
It's important to note that robotic nurses don't decide courses of treatment or make diagnoses (though robot doctors and surgeons may not be far off). Instead, they perform. routine and laborious tasks, freeing nurses up to attend to patients with immediate needs. This is one industry where it seems the integration of robots will lead to collaboration, not replacement.

This is not the world we know. This world is controlled by computers. Men and women can be seen, but they are following the orders given to them by machines. The machines were designed by mad scientists, but at some point even the mad scientists were taken over by their super-inventions.
Does this sound familiar？ You have probably read something like it in magazines or books, or seen it in a film. Why is it so popular？ One of the reasons is that it reflects the fears of many people; fear of the unknown fear of what is not understood or, at least, fear of something that is not completely understood.
The fact is that every day it seems that computers take control of another area of our lives. Some
factory jobs are now done by robots and the robots are controlled by computers. Our bank accounts are managed by computers. At the airport, our tickets are sold by a computer. Certainly, many of these operations are made more
efficient by computers, but our admiration is sometimes mixed with unsafe feelings. And this lack of safety is caused by the fact that we do not know how computers do these things, and we really don't know what they might do next. But we can find out how computers work, and once we understand them, we can use computers instead of worrying about being used by them. Today, there is a new generation of computer wizards who know exactly how computers get things done. These young men and women, usually university students, are happy to sit for hours, sometimes for days, designing programs, not eating, not sleeping, but discovering what can be done by these wonderful slaves which they have learned to control. These computer wizards have learned to use the computer and search for new tasks for their machines.

A：computers can be controlled by man
B：there should be more people devoted to computers
C：only young people are interested in computers
D：more time and energy is required to control computers
(4)、This passage is probably written to suggest that ______ .
A：some day computers can deal with all human problems
B：computers can be used in place of traveling to our jobs

For anyone who hates doing yard work, your new best friend may have arrived. A robot can autonomously shovel snow, collect leaves and cut grass.

“We’re trying t o help people not spend time on yard work，”said Steven Waelbers, the designer of t he robot. “We want people to enjoy t heir free time with their family.”The electric robot can run by itself in right directions with the help of two beacons(信号塔) that must be placed in the yard. the robot includes a camera and ultrasound sensor (超声传感器) that Waelbers said would stop quickly when it finds pets and people.

Owners of the robot will need t o regulate t he values stored in the robot. then it will confirm the task it’s going to take. Before the robot operate by itself, an owner must manually wheel it around the yard 一 taking it around any obstacles like trees, bushes or mailboxes. By doing this, the robot is taught how long and wide the lawn is, and won’t accidentally(不小心) destroy your rose hush or run to the neighborhood.

Once this setup is complete, and the $3,999 robot has been trained on where to cut grass, rake leaves and shovel snow, it operates without any supervision.

Waelbers has always loved to build robots and play with electronics. He started work on a high-tech company after his father asked him to make a robot that would shovel snow for him. Waelbers plans to start sales in early 2017.

Robots differ from automatic machines ________ after completion of one specific task，they can be reprogrammed by a computer to do another one.

Futurists love computers. After all,40 years ago electronic digital computers didn't exist; today microchips as tiny as a baby's fingernail are making all sorts of tasks faster and easier. Surely the future holds still more miracles.
Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform. some sight and hearing functions, which could make life easier for the blind and deaf. They're also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who's lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom.
Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work -- they'll just turn on a terminal
A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform. tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days.
These modern and potential computer uses are possible because of the silicon microchip.
These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor.
As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer.
Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!
What is the purpose of the passage？
A．To tell the readers what computers will look like in the future.
B．To show the close relations between man and computers.
C．To tell the readers how important silicon microchips are.
D．To talk about the possible future uses of computers.
