Ⅲ. 补全短文。
根据短文内容,从方框中选出能填入空白处的最佳选项。(其中有一项为多余选项)
Scientists recently announced the world's tiniest remote-controlled(遥控的) robots. These robots are small enough to sit on a coin. The scientists were so excited.
1
The news came from Northwestern University. Last week, scientists at Northwestern University introduced several tiny robots they have created. The tiniest is shaped like a crab and is just half a millimetre(毫米) wide. 2 But they can be controlled from a distance(距离) by using lasers(激光).
3 But the robots are also not too slow because of their tiny size. Right now the robots aren't all that useful. 4 But the scientists say these robots are an important step toward creating more helpful tiny robots.
The scientists say that one day tiny robots like these may be able to work in very small areas, such as human's vessels(血管). It's possible that scientists can build very tiny robots. 5
Using similar building methods, the scientists can create a number of different tiny robots. "Our methods allow us to build walking robots with almost any sizes or 3D shapes," says John Rodgers, one of the scientists.
A. The robots can't move fast.
B. All they can do is only moving.
C. The robots don't have any power of their own.
D. They were also able to control the movement of the robot in different directions.
E. They predict that one day these robots may work in areas which are too small for tools.
F. Hope one day those tiny robots can travel inside the human body to help deal with medical problems!

答案
【解析】：我们根据上下文逻辑逐一确定答案：
1. 空前说明科学家成功研发出极小的遥控机器人，他们十分兴奋，D选项补充说明他们还能控制机器人向不同方向移动，承接上文科学家兴奋的状态，引出后文对研发团队的介绍，符合语境。
2. 空后出现转折词But，说明机器人可以通过激光远程控制，C选项表示这些机器人自身没有动力，和后文形成合理转折，逻辑通顺。
3. 空后But提到受极小尺寸的影响，机器人的速度也不算太慢，A选项说明机器人没法快速移动，和后文形成转折关系，符合语境。
4. 空前说明目前这些机器人还不是很实用，B选项解释它们现在只能完成移动这一个动作，对应前文“没那么有用”的描述，和后文“是研发更实用微型机器人的重要一步”形成转折，逻辑合理。
5. 空前提到未来这类微型机器人可以在血管这类极小的区域工作，E选项说明科学家预测未来这些机器人可以在常规工具无法进入的极小区域工作，承接前文内容，引出后文对制造方法的介绍，符合语境。
本题多余选项为F。
