机器人发展史
机器人大致经历了三代发展：第一代机器人是简单个体机器人，只具有记忆、存储能力，按相应程序重复作业，但对周围环境基本没有感知与反馈控制能力。第二代机器人为群体劳动机器人。它能够获得作业环境和作业对象的有关信息，进行一定的实时处理作业，在工业生产中得到广泛应用。第三代机器人是目前正在研究的“智能机器人”。它不仅具有更加完善的环境感知能力，而且具有逻辑思维、判断和决策能力，可根据作业要求与环境信息自主进行工作。

当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. hundreds　句意：鲁迅爱读书。当他年轻的时候，他读了数以百计的书籍。hundreds of 为固定短语，意为“数以百计的”。
2. dangerous　由句意“在街道上踢足球很危险”可判断此处填danger的形容词形式dangerous作表语。
3. fell　由句意“昨晚许多树在暴风雨中倒了”可知答案为fall的过去式fell。
4. impossible　根据句意“对我来说6点之前到中央公园是不可能的，那太早了”可知答案为possible的反义词impossible。
