it's a good idea to buy a robot. It will change their lives in many 
ways. They will have more free time for hobbies. It can also help them do some housework. 
It can wash clothes, cook food as well as sweep the floor for them.
       However, other students don't think so. If the robot catches a virus, it will cause too much 
trouble. They may find breakfast in the washing machine and clean shirts in the dustbin. In 
the end, they may have to send it back to the robot shop. Besides, more and more people will 
lose their jobs because of robots.
       I think robots will make a great difference to our lives. They will bring us more advantages 
than disadvantages. I hope to own a robot in the future.
⑴ inventor(s)
句意：这个机器人的发明者说，有了这个机器人，救援人员在地震中可以有更多的时间来拯救生命。
根据said可知，本处为表示某个/些人的单词，根据所给单词，可知本处意为“发明者”，不确定发明者是一个人还是多个人。因此填inventor或inventors都可以。

⑵ an
句意：这个机器人的发明者（们）说，有了这个机器人，救援人员在地震中可以有更多的时间来拯救生命。
本处泛指在一次地震中，因此用不定冠词。earthquake是元音音素/ˈɜː/开头的单词，因此用不定冠词an

⑶ to develop
句意：它大约有三米长，花了大约四年的时间来开发。
固定句式：It takes sb. some time to do sth. 做某事花了某人多长时间，故本处为不定式to develop

⑷ latest
句意：它可以昼夜工作，还可以发送来自地震地区的最新图片。
分析可知，本空修饰名词pictures，故本空填形容词。发生地震后，震区最新的照片很重要，因此这里指“最新的”，故填latest

⑸ itself
句意：我们只是在它里面设置了它应该去的地方的信息，然后它自己起飞和降落。
by oneself 意为 独自地，单独；
根据前面的it，可知此处的反身代词是itself

⑹ if/when/as
句意：如果环境变化，这个机器人也会改变。/当环境变化，这个机器人也会改变。/随着环境的变化，这个机器人也会改变。
根据句意，此处连接时间状语从句，因此用if/when/as都可以。

⑺ unable
句意：它的主要工作是在人类救援人员无法到达的地方寻找生命迹象。
人类救援者去不了的地方，这个机器人可以发挥作用。
因此本处指“无法、不能”，填unable

⑻ harmful
句意：摄像头也可以作为探测器，发现被困的人并检测有害气体，安装在机器人身上。
gases（gas的复数形式，意为气体）是名词，因此本处用形容词harmful来修饰

⑼ is put
句意：摄像头也可以作为探测器，发现被困的人并检测有害气体，安装在机器人身上。
camera和put是被动的关系 ，因此用被动语态；
本文用的是一般现在时，camera是名词单数，因此本处填is put

⑽ as
句意：专家表示，这些机器人将尽快投入生产，并成为国家地震救援队的一部分。
分析句意，本处表示作为，因此用固定短语serve as（充当，担任）。本空填as
       We had a discussion about whether it is necessary to buy a robot last week. Opinions are different. Some students think it's a good idea to buy a robot. It will change their lives in many ways. They will have more free time for hobbies.  It can also help them do some housework.  It can wash clothes, cook food as well as sweep the floor for them. 
       However, different people have different ideas. Other students don't think so. If the robot catches a virus, it will cause too much trouble. They may find breakfast in the washing machine and clean shirts in the dustbin. In the end, they may have to send it back to the robot shop. Besides, more and more people will lose their jobs because of robots. 
       I think robots will make a great difference to our lives. They will bring us more advantages than disadvantages. I hope to own a robot in the future.
