e the strength (动力)to do it(与B不一致), ”he says. 以上的句子明确地提出“机器人飞不起来”。
　　4 B。分析：问题问“什么测量机器人升起的高度?” 被选项是一些测量器材，利用被选项的内容作为答案线索，这样发现答案相关句：The team attached(系) the robot to two vertical rods, so it could slide (滑)up and down. At the start of a test, the robot was suspended (悬挂)by an elastic band. A movement detector measured how much lift, if any(如果能升起的话) , the robot produced for any given movement.
　　划线结构表明测量工具是B(运动探测器)
　　5 D。分析：该题的考点明确：考察段落中定冠词结构的指代内容。在最后一段中找到答案相关句：Feedback from the movement detector let the program work out which sets of instructions were best at producing lift. The most successful ones (指代前面的instructions)were paired up (配对)(与A相关)and “offspring” sets of instructions were generated by swapping (交换)instructions randomly(任意地) between successful pairs. These next-generation instructions were then sent to the robot (then 的出现暗示前面的内容还应该提到了一个具体的动作，这个动作是先发生的，也应该是这个过程中的一部分内容)and evaluated before breeding(培育) a new generation, and the process was repeated(重复).
　　以上的两个句子内容的表明这个被重复的过程包括“成功指令的配对”，包括“把下一代指令传送到机器人那里”，包括“把这些指令进行评价”，因此D是答案。
