WASHINGTON – It’s a great achievement that inspires notions of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a novel ability: it can heal its own damage.
The new robot, which looks like a splay – legged, four – footed starfish can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places. “There is a need for planetary robotic rovers to be able to fix things on their own,” says Josh Bongard, a professor in the University of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built – in computer. From the formation it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking – it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One pellicle spot is the ocean floor. That dark and dangerous undersea terrain might be a good choice for a robot the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
46.The newly designed robot distinguishes itself from the former ones because it___________
A.can communicate with people on the earth about their problems
B.works according to a certain computer program
C.can find its problems and solve them automatically
D.can explore unfamiliar places
47.An example is given in the fourth paragraph in order to explain that the robot ___________
A.is used to create new programs
B.has typical robot functions
C.has sensors to observe its movements
D.can gather information and adapt to new conditions
48.The underlined word “resilient” in the last paragraph means the robot is ___________.
A.creative B.newly made C.a(chǎn)ble to recover D.informative
49.Which of the following is TURE about the robot “Starfish”?
A.It was spoken highly of by people for its special ability?
B.It will stumble and fall if damaged.
C.It can grow its legs again once they are broken.
D.It has started to work on the ocean floor.
50.What might be the best title of the passage?
A.How does the Starfish Robot work
B.Do – It – Yourself Robot Repair
C.Robots Designed to Work On Other Planets
D.New Robot Helping Us In Many Ways

Dear Daughter:
As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.
First, I want to tell you how proud we are.Getting into Columbia is a real testament of what a great well-rounded student you are.You should be as proud of yourself as we are.
Your college years will be the most important years in your life.It is in college that you will discover what learning is about.This will be the period where you go from teacher-taught to master-inspired, after which you must become self-leamer.So do take each subject seriously, and even if what you learn isn't critical for your life, the learning skills you acquire will be something you cherish forever.
Follow your passion in college.Take courses you think you will enjoy.Don't be trapped by what others think or say, but make up your own mind.
Most importantly, make friends and be happy.College friends are often the best in life.Pick a few friends and become really close to them—pick the ones who are genuine and sincere to you.Don't worry about their hobbies, grades, looks, or even personalities.
Start planning early —what would you like to do? Where would you like to live? What would you like to leam? I think your plan of studying fashion is good, and you should decide where you want to be, and get onto the right courses.
Whether it is summer-planning, or coursework planning, or picking a major, or managing your time, you should take control of your life.I will always be there for you, but the time has come for you to be in the driver's seat - this is your life, and you need to be in control.Being in control feels great.Try it, and you'll love it!
College is the four years where you have:
●he greatest amount of free time
●the first chance to be independent
●the most flexibility to change
●the lowest risk for making mistakes
So please value your college years ?make full use of your free time, become an independent thinker in control of your destiny, be bold to experiment, leam and grow through your successes and challenges.
May Columbia become the happiest four years in your life, and may you blossom into just what you dream to be.
Love,
Dad (& Mom)
