Soft robots， which can move around the ocean without harming sea life， are ideal for underwater exploration. However， they are not so welcome in robot market because they are extremely slow and have a hard time operating through the water. But that may change soon thanks to a self-driven soft robot created by researchers at the University of California， San Diego. The recently-developed robot， which resembles a paper lantern， was primarily built using soft materials. Its flexible ribs are attached to a circular plate at both ends. An adjustable nozzle（喷嘴）fitted on one side helps draw in and jet （射出） water each time the robot shrinks. The resulting jets of water enable it to swim forward， similar to a squid （乌贼）. A plate holds a waterproof component that can house a camera to record data， which is of great value to further development of the robot. It also has its own power source， allowing it to float autonomously for long periods of time. "Essentially，we recreated all the key features that squids use for high-speed swimming. This is the first robot that can achieve these jets of water by changing its body shape，which improves swimming efficiency，" said Professor Michael T. Though the squid robot has not been tested in open waters，it successfully swam around coral and fish in a large tank in the UC San Diego Birch Aquarium. What's more， the robot clocked an impressive speed of 18 to 32 centimeters per second， or about half a mile per hour. Though nowhere close to real squids， it is faster than most other soft robots. "After we were able to improve the design of the robot so that it would swim in a tank in the lab，it was especially exciting to see that the robot was able to successfully swim in a large tank among coral and fish， showing its possibility for real-world applications，" said Caleb Christianson，who led the study as part of his Ph. D paper.（1）Why were the previous soft robots seldom used？ ____ A. Their application places are limited.B. They do great damage to sea life.C. They are very difficult to control.D.

题目解答
答案
（1）C. 细节理解题。根据第一段第二句However， they are not 80 welcome in robot market because they are extremely slow and have a hard time operating through the water.（然而，它们在机器人市场上并不受欢迎，因为它们的速度非常慢，而且在水中很难操作。）可知，早期的软体机器人在机器人市场中并不受欢迎，因为它们在水中移动得非常慢而且难以在水中操控。故选C.
（2）D. 细节理解题。根据第二段第四句The resulting jets of water enable it to swim forward， similar to a squid（乌贼）.可知，机器人在水中收缩产生的水流使它能够向前游动，就像乌贼一样。由此可知，新型软体机器人在水中（向前）移动的方式和乌贼游动的方式相似。故选D.
（3）D. 细节理解题。根据第三段最后两句What'smore，the robot clocked an impressive speed of 18 to 32 centimeters per second，or about half a mile per hour. Though nowhere close to real squids， it is faster than most other soft robots.（更重要的是，机器人的速度令人印象深刻的18至32厘米每秒，或约半英里每小时。虽然没有地方接近真正的鱿鱼，但它比大多数其他软机器人都快。）可知，这种新型机器人的行进速度大约是每小时半英里。尽管与真正的乌贼（的游动速度）相差甚远，但它比其他大多数软体机器人（的移动速度）都要快。故选D.
（4）A. 观点态度题。根据最后一段内容"After we were able to improve the design of the robot so that it would swim in a tank in the lab，it was especially exciting to see that the robot was able to successfully swim in a large tank among coral and fish， showing its possibility for real-world applications，" said Caleb Christianson，who led the study as part of his Ph. D paper.（作为博士论文的一部分，领导这项研究的Caleb Christianson说："在我们能够改进机器人的设计，使其能够在实验室的水槽中游泳之后，看到机器人能够在珊瑚和鱼类中成功地在一个大水槽中游泳，这让人特别兴奋。"）可知，Caleb Christianson 表示看到这种新型软体机器人能在水族箱中成功地游冰是一件很令人兴奋的事，这也展示了它在现实世界中被应用的可能性。由此可推知， Caleb Christianson对这种新型软体机器人持积极态度。结合选项A. Positive积极的；B. Critical批判的；C. Uncaring不关心的；D. Doubtful怀疑的，故选A.
