Ⅰ. 机器人发展史
早在三千多年前的西周时代，我国就出现了能歌善舞的木偶，称为“倡者”，这可能是世界上最早的“机器人”。上世纪五六十年代，出现第一代机器人，它属于“示教再现”(Teach-in/playback)型机器人，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。进入80年代，出现了第二代机器人——有感觉的机器人。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，而且还具有逻辑思维、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。

观察与思考：
1. However, they agree it may take hundreds of years.
hundreds of 意思为“许多，大量的”，后跟可数名词复数。当hundred 表示具体数量时，不可以+s，也不可以和of 连用。
例如：400 four hundred
练习：There are ________books in our school library.
hundred of B. hundreds of C. nine hundreds D. nine hundreds of

【练习】汉译英。

3. For example, there are already robots working in factories.
There be sb. /sth. +doing sth. 有某人正在做某事
e.g. Listen! E.g. There is a girl singing in the next room.
4. That may not seem possible now, …
seem意思为“似乎，好像”，其后可跟形容词或to do.
【练习】
① 她似乎病了。She _______ ______ _________ _________.

②看，机器人似乎动了。Look! The robot _______ ________ _________.
5 ...robots will never be able to wake up and know where they are.
