九、提升题 春节联欢晚会上的机器人表演令玲玲和 Sally 惊叹不已。请阅读短文,选择正确的答案。
The Spring Festival Gala was great! Many smart robots gave us great shows. Some robots did Chinese kung fu. Some danced. Some acted(表演) in short plays. They moved well and looked amazing. Do you know how these robots work? Let's learn!
Every robot has three important parts: sensors(传感器), a controller(控制器) and actuators(执行器). Sensors are like the robot's "eyes" and "ears". They collect light and sound. The controller is like the robot's "brain". It gets information from sensors and sends orders. Actuators are like the robot's "hands" and "legs". They turn electricity into movements(动作) like jumping or smiling.
These robots show us the power of technology. They are our good friends. We will see more amazing robots soon!

【分析】本题为英语阅读理解选择题，解题思路是先通读短文把握大意，再针对每个小题的问题，回到原文定位关键信息，逐一比对选项排除错误答案，选出正确选项。具体来说，第1题需查找机器人在春晚的表演内容；第2题找机器人的三个重要组成部分；第3题对应机器人“大脑”的部件；第4题明确执行器的功能；第5题归纳短文主旨。
【解析】1. 定位原文第一段“Some robots did Chinese kung fu.”，A选项“做饭”、B选项“打篮球”均未提及，故答案为C；2. 定位第二段第一句“Every robot has three important parts: sensors, a controller and actuators.”，A选项是机器人的身体部位、B选项是传感器收集的内容，故答案为C；3. 定位第二段“The controller is like the robot's 'brain'.”，故答案为B；4. 定位第二段“Actuators... They turn electricity into movements...”，A选项是传感器的功能、B选项是控制器的动作，故答案为C；5. 短文先介绍春晚机器人的精彩表演，再讲解机器人的三个重要部分及工作原理，A选项“如何制造机器人”未提及、C选项“春晚历史”偏离主题，故答案为B。
【答案】1.C 2.C 3.B 4.C 5.B
【知识点】英语阅读理解、细节理解、主旨大意
