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 2017.26. This article mainly talks about()A. a newly-designed robotB. The founder of a companyC. problems with a new product27. According to Steven Waelbers, the robot is designed to()A. encourage people to do exerciseB. help people keep healthy and fitC. make people enjoy family time28.the robot would stop in front of pets and people thanks to()A. the remote controllerB. the ultrasound sensorC. the big and square yard29. Which of the following steps should be done in the first place?()A. An owner must wheel the robot around the yard by himself.B. The robot learns and stores the length and width of the lawn.C. The robot operates the task it’s going to take without supervision.30. Which of the following about Waelbers is TRUE?()A. He didn’t love building robots when he was a young boy.B. His father asked him to make a robot that could play balls.C. He is starting to sell this snow-shoveling robot in early 2017.

One study conducted by a psychologist(121)of interviewing workers before and after the installation of a robot. The robot was used to control a matching process of stamping and assembling metal parts. Prior to installation, much of the work done by skilled machinists. After installation, the robot did the work, but the workers controlled the robot through the robot through a control panel. The results of the study indicated that the workers praised the robot(122)eliminating the physical labor and fatigue(123)the manual operation, but complained of more and continued stress. Prior to installation of the robot, there was time for talking or short periods of relaxation between jobs. Now, however, because of the speed of the robot, there was a need for constant scanning and monitoring of the operation(124)performed by the robot has the installation of the robot created a better work environment? Has the change from physical labor to mental stress resulted in an improved(125)of life? Much additional research is necessary.A．OfB．consistedC．forD．being

第二十二篇 RealWld Robots When you think of a robot, do you envision ashiny, metallic device having the same general shape as a human being,perfming humanlike functions, responding to your questions in a monotonevoice accentuated by high-pitched tones beeps? This is the way many of usimagine a robot, but in the real wld, a robot is not humanoid at all. Insteada robot often is a voiceless, box-shaped machine that efficiently carries outrepetitive dangerous functions usually perfmed by humans. Today’s robot is me than an automatic machine that perfms one taskagain again. A modern robot is programmed with varying degrees ofartificial intelligence—that is, a robot contains acomputer program that tells it how to perfm tasks associated with human intelligence,such as reasoning, drawing conclusions, learning from past experience. A robot does not possess a human shape fthe simple reason that a two-legged robot has great difficulty remainingbalanced. A robot does, however, move from place to place on wheels axlesthat roll rotate. A robot even has limbs that swivel move incombination with ts mots. To find its way in its surroundings1, arobot utilizes various built-in senss. Antennae attached to the robot’s base detect anything they bump into. If the robot starts to teeteras it moves on an incline, a gyroscope a pendulum inside it senses thevertical differential. To determine its distance from an object how quicklyit will reach the object，the robot bounces beams oflaser light ultrasonic sound waves off obstructions in its path2. These other senss constantly feed infmation to the computer, which then analyzesthe infmation crects adjusts the robot’sactions. As science technology advance, the robot too will progress in itsfunctions use of artificial-intelligence programs. 词汇： envision v. 想象，预想 device n. 装置 accentuate v. 强调，重读 artificial intelligence n. 人工智能 limb n. 臂 antennae n. 天线 incline v. 倾斜 pendulum n. 钟摆 ultrasonic adj. 超声的 metallic adj. 金属的 monotone n. 单调的 humanoid adj. 像人的 axle n. 轮轴 rotate v. 旋转 swivel n. 旋转 teeter v. 摇晃 gyroscope n. 陀螺仪，回转仪 vertical n. 直立的 注释： 1.To find its way in its surroundings...：为了在周围找到路…… 2.the robot bounces beams of laser light ultrasonic sound waves off obstructions in its path：机器人发射激光束和超声波，反射到障碍物上(以此来探知路径)。 练习：3.The last paragraph suggests that futurerobots will beA me humanlike inbehavi actions.B me like automaticmachines.C better able to moveon inclines.D better equippedwith laser light senss.
