题目内容
1.In some science fiction movies,evil robots refuse to die,no matter how hard people fight back.Now science fiction has become science fact.For the first time,scientists have made a robot that can take a beating (挨打) and keep on going.Scientists from Cornell University made the robot,which looks like a spider with four legs.
Until now,even the most advanced (先进的) robot was almost certain to break down when it was damaged.That is because its computer inside simply doesn't know how to make the machine work after its shape has changed.
To deal with this problem,the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working.They all give signals to the machine's software.Using this information,the computer can then figure out the machine's shape at any moment.
The new technology is a big advance in robot-making,scientists say,and it's far from scary.It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them.It might also help scientists understand how people and animals figure out their own sense of place in space.
"It has been difficult to design robots that can work well when the environment changes or when it's damaged,"says Olaf Sporns of Indiana University in US."With this work,we are nearer to solving this problem."
36.Why do robots easily break down when they are damaged?D
A.They cannot repair themselves.
B.The computer has changed a lot.
C.They have no computers inside.
D.The computer cannot work if the robot changes.
37.The new technology allows the robot toB.
A.do house work for humans
B.keep working after being damaged
C.remember a lot of information
D.tell people where it is
38.The underlined word"them"in Paragraph 5refers toC.
A.sensors
B.robots
C.arms and legs
D.scientists
39.How do the sensors in the robot work?C
A.They can replace the computer when it's broken.
B.They can find out where the damage comes from.
C.They help the computer learn the robot's condition.
D.They can send signals to the person who uses the robot.
40.The passage is probably fromA.
A.a newspaper
B.an advertisement
C.a tour guide
D.an application.
分析 文章大意:
此篇文章主要介绍的科学家通过改进技术,来提高机器人的运转性能.在很早以前,当机器人的外观或者零件受损之后,电脑就不能指挥机器人进行运动,这个机器人也就坏了.现在,科学家通过改进技术,对机器人进行完善,添加了几个高科技的传感器,可以指导电脑弄清楚机器人的状况,使得机器人可以在零件受损的情况下正常运行.
解答 36.D,推理判断题,文中提到"That is because its computer inside simply doesn't know how to make the machine work after its shape has changed"当机器人的形状发生变化或者被损害后,电脑在这种条件下不知道如何运行内部机器,由此确定选择D.
37.B,推理判断题,文中提到"Using this information,the computer can then figure out the machine's shape at any moment"对于改装之后的机器人,电脑可以在任何突发状况下运行内部机器,从而使机器人正常工作,由此确定选择B.
38.C,推理判断题,文中提到"It may someday help scientists create better artificial (假的) arms and legs"他可以帮助科学家制造更加逼真的假肢,手臂或者腿,由此确定them指的是这些假肢,选择C.
39.C,推理判断题,文中提到"two sensors (传感器) that read how the machine is working.They all give signals to the machine's software.Using this information,the computer can then figure out the machine's shape at any moment"传感器可以读取机器人的工作模式,并将信息传输到电脑,电脑根据这些信息就可以知道机器人的工作状况,由此确定选择C.
40.A,推理判断题,此篇文章主要介绍的科学家通过改进技术,来提高机器人的运转性能,由此可以确定应该是一段说明性的文字,介绍的是科学技术的发展,所以推断应该是在报纸上.
点评 对于阅读表达题,一定要记得首先通读全文,了解文章大意,然后再根据文章关键词,关键句,掌握细节问题,并进行推理判断,再去回答具体的问题.
