A Robot Fish has been developed by National University o Wap版

试题详情及答案解析

A Robot Fish has been developed by National University of Singapore’s researchers from the Department of Electrical & Computer Engineering．This robot fish has movements which have been inspired by the movements of the carp（鲤鱼）．
There are various purposes that it can be used for．It can help in underwater archaeology （考古学）．For example, it can enter a sunken city where human divers cannot enter．Just like a fish , it can also look at all the comers of particular wreckage．This robot can also be used for general purposes such as detection of leakages in a pipeline or for laying down communication cables across oceans．It also has possible military uses．
In order to copy carp movements, Mr．Fan studied the movements of the fish for around 3 months．He studied all the different movements of carp using different cameras and then converted these movements mathematically to transfer this data to the robot using many actuators（驱动器）．
Professor Xu commented on the robot that the current models that copy fish movements are capable only of 2D movements which limits their capability as they are not able to dive into water．He said that his model is the first model with 3D movements which allows it to dive as well as float with the help of its fins, just as a normal fish would do．Hence, this fish model robot has much greater movement capability．It would be much harder for enemies to detect as compared to traditional ones when used for military purposes．
The researches want to make their robot fish even smaller, more realistic while adding more sensors such as GPS and video camera to it．This will improve its autonomous 3D movement．They are also planning to test the fish by giving it more difficult tasks such as detecting various objects．
【小题1】The author gave an example in paragraph 2 _____．

A．to introduce the Robot Fish can help in underwater archaeology

B．to show the Robot Fish can be used for general purposes

C．to show the Robot Fish can lay down communication cables across oceans

D．to tell us the Robot Fish has possible military uses

【小题2】Which is NOT true about the 3D Robot Fish?

A．It is capable of diving into water．

B．It cannot dive into water．

C．It can float using its fins．

D．It is difficult to detect．

【小题3】What' s the main idea of the last paragraph?

A．The researchers will give the robot more difficult tasks．

B．The researches want to make their robot smaller．

C．The researchers are going to test the robot．

D．The researches plan to improve the robot．

【小题4】Which of the following would be the best title for the text?

A．First Robot Fish with Autonomous 3D Movement used widely

B．First Robot Fish with Autonomous 3D Movement treading the ocean

C．First Robot Fish with Autonomous 3D Movement created in Singapore

D．First Robot Fish with Autonomous 3D Movement's general purposes

答案：【小题1】A
【小题2】B
【小题3】D
【小题4】C

试题分析：本文介绍的的是一只由新加坡国立大学研究发明的机器鱼，通过计算机和电流控制是如何运作，以及它的用途和功能。
【小题1】细节推断题。第二段中“This robot can also be used for general purposes such as detection of leakages in a pipeline or for laying down communication cables across oceans．”可以看住机器鱼可以用于深海油气运输导航，也可以用于水下通讯电缆，故选A。
【小题2】细节推断题。第四段中“He said that his model is the first model with 3D movements which allows it to dive as well as float with the help of its fins, just as a normal fish would do．”可以看出3D模型的机器鱼可以像正常的鱼一样，借助鳍潜水，故选B。
【小题3】主旨大意题。最后一段中“The researches want to make their robot fish even smaller, more realistic while adding more sensors such as GPS and video camera to it.”中可以看出这个研究让机器鱼更加小型轻便，加入了更多传感器如GPS何摄像机，使它变的更加实用，故选D。
【小题4】主旨大意题。本文主要讲述的是3D技术的机器鱼的研究和实用，属于客观陈述，故选C。
