重点句子点拨：

1.Do you think there will be robots in people's homes? 你认为在人们的家里将来会有机器人吗？

Do you think...? 结构通常用来征求对方的意见或看法，后面接宾语从句，从句用陈述语序。本句的肯定回答用"Yes,there will."，否定回答用"No,there won't."。

例句：---Do you think there will be robots in school?你认为学校将来会有机器人吗？

---Yes, there will. 是的，会有。

拓展： do you think还可以用作插入语，在特殊疑问句中放在特殊疑问词之后，疑问句其他部分用陈述语序。

2. I think every home will have a robot.我认为每个家庭都将有一个机器人。

点拨："will+动词原形"构成一般将来时。

（1）一般将来时表示将来某个时间要发生的动作或存在的状态，也表示将来经常反复发生的动作，常与表示将来的时间状语连用。如tomorrow,next year,"in+时间段"等。一般将来时由"助动词will+动词原形"构成，第一人称还可以用shall。

例句：I will\shall go to the park tomorrow.我明天要去公园。

（2）will和be going to 都可以表示将来，但有区别。will表示单纯的将来概念，而be going to 强调事先经过考虑、安排而计划或打算要做某事，或者概括某种迹象判断某事有可能发生。

（3）一般将来时的否定构成：在will\shall 后面加not。will not可缩写为won't。
