MIT's Computer Science and Artificial Intelligence Lab (CSAIL) has released a video of their ongoing work using muscle signals to control devices. Their latest involves full and fine control of drones (无人机), using just hand and arm gestures to pilot through a series of circles.

This work is impressive not just because they're using bio-feedback to control the devices, instead of optical (光学的) or other kinds of gesture recognition, but also because of how specific the controls can be, setting up a range of different potential applications for this kind of remote tech.

This particular group of researchers has been looking at different applications for this tech, including its use in collaborative robotics (协作机器人) for potential industrial applications. Drone piloting is another area that could have big applications in terms of real- world use, especially once you start to imagine entire groups of these taking flight with a pilot provided a view of what they can see via VR. That could be a great way to do spot surveying for construction, for example, or remote equipment check of dangerous places and other construction that's hard for people to reach.

The development of drones is just part of the team's work. Smooth robot and human interaction is the ultimate goal of the team working on this tech. Researchers believe the process should be as easy when controlling and working with robots. They say thinking and doing are essentially happening at the same time when we communicate with our environment, but when we act through machines or remote tools, there's often something lost in translation, showing slow learning, and the requirement of lots of training. Therefore, much more work is going on.

(1)、What is impressive about the work?
A、It has found the best way to control robots. B、It uses gestures to accurately control the devices. C、The researchers are particular and famous experts. D、Its remote tech has been used in some industrial areas.
(2)、What does paragraph 3 try to tell us?
A、The big changes of future industries. B、The new way to spot construction sites. C、The possible application of the tech in real world. D、The benefits that VR technology brings to drones,
(3)、What is the aim of the research according to the last paragraph?
A、To make it possible for robots to think. B、To speed up the learning process of robots. C、To meet the requirement of robot controlling. D、To enable more natural human-robot communication.
(4)、What's the best title for this text?
A、New Applications of Drones B、Muscle Signals Can Pilot Drones C、MIT's New Research on Robots D、Possibilities of New Robots

    The Come-back Coffeehouse   The sign in the window read "Carl's Coffee Shoppe," spelled the old-fashioned way. Hallie shook her head and wondered how many times she had suggested an alternative. She entered the shop and saw only one person.

    "I could help with the books, Dad", Hallie offered,"There's not much you could do." Her father signed. "How about if you clean the counters instead?" His statement made her feel like a little girl instead of a senior in high school. Hallie sprayed some cleanser and ran a cloth over the worn counter tops . After she had washed a few of the old eggshell-colored cups, she began her homework. At closing time, Hallie's parents sat beside her. "You know the shop has not been profitable lately," Mr. Rhodes began. "We need to decide if it is even worth keeping it open." "We're going to visit Uncle Harold over spring vacation." Mrs. Rhodes continued. "He can look over the books and tell us what our options are. You and AuntTess will run the shop for the week."

    By spring vacation Hallie was ready for an adventure. Hllie's parents gave some instructions, and said good-bye. Hallie stared absently out the window at the passersby: young people on their way to work, and kids on their school vacation. They were not the same people that her grandpa Carl had served. Suddenly Hallie had an idea. She confided in Aunt Tess, who approved. The two eagerly set to work.

At the end of the week, Hallie was coming out from the kitchen when she saw her parents standing in the shop, confused. She smiled asher parents stared at the teens around the counter and the young families seated at the tables.

    "Welcome back!" Hallie swept her arms to present there staurant's cheerful new decoration. Bright, attractive coverings spread over the tables, and modern posters hung on the walls, while, colorful mismatched dishes contributed to the pleasant atmosphere."

    "I brought board games from home," Hallie added excitedly, "and the bookstore down the street donated the posters. When we talked to our friends about what we were doing, they were happy to give us some dishes." Hallie held her breath as she waited for her parents' reaction.

    "Everyone certainly seems to like the changes," noted Mrs. Rhodes.

    "Speaking of changes," Mr. Rhodes said,"I see our name has changed, too."

    "Do you mind? I changed our name to 'Come-Back Coffeehouse'to make the shop sound welcoming, as in 'Please come back again'..."

    A smile spread across her father's face. "The newname is fitting. Thanks to you, this place certainly has made a come back!"

    On the night of December 8, 1992, when he was standing in a parking lot talking to friends, Tracy March jumped to the top of a car, as he had done a hundred times before. This time, though, Tracy lost his balance. His head struck the ground, hard.

    All night, Cory, Tracy's mother, stood next to her son, who was lying in a hospital bed, his brown eyes fixed in a lifeless stare. She remembered that Tracy had once mentioned organ donation. Maybe I can spare another family this pain, she thought. When the time came, she and her husband Bill signed the forms permitting his organs to be donated.

    Tracy was declared dead the next day. Twenty-four hours later, in a Boston hospital, Tracy's liver was made part of my husband, David, who was suffering from a hopeless liver disease.

    Months later, we learned from the local organ bank that the donor's parents wished desperately to meet someone who had gained life through the gift from their son. A meeting was arranged by the organ bank to bring together two families linked by the most bittersweet ties imaginable.

    The meeting was risky, but worth it. We talked for 3 hours. They showed us a picture of Tracy. We learned how he had lived and died. We learned something about Bill and Cory too.

    For the Marches, seeing David and knowing he was well seemed to ease their suffering. I'll never forget seeing David's tall figure stopped over Cory, her arms around his waist, as a mother would hug a son. For a long time they held each other tight. It was hard to know if she was saying hello or good-bye. Maybe she was saying both.
