Language points
1.Do you think there will be robots in people’s homes
你认为人们家里将有机器人吗？
这是一个含有宾语从句的主从复合句。其中，“Do you think”是主句部分，“there will be…”是从句部分，从句部分整个句子作为think 的宾语。
如果do you think放在句中，则为插入语，常放在疑问词之后，结构为：疑问词+do you think+主语+谓语+其他成分？
Do you think he is a teacher 你认为他是一名老师吗？
there will be意为“将有；会有”，是there be句型的一般将来时，可以与there is/are going to be进行句式转换，它们相对应的否定形式是there won’t be或there isn’t going to be。
特别注意：这两种形式中的be都是be动词原形，不能改成其他动词。
例：There is going to be a sports meeting tomorrow.
明天将有一场运动会。
there be句型遵循“就近一致”的原则，即离be近的是单数或不可数名词，be动词就用单数；离be近的是复数名词，be动词就用复数。
There is a book and two pens on the teacher’s desk.
讲台上有一本书和两支笔。
There are two pens and a book on the teacher’s desk.
讲台上有两支笔和一本书。
2. People will live to be 200 years old.
人们将会活到200岁。
live to be+基数词+years old,意思是“活到……岁”。其中live作动词，意为“活……；生活”。
Dogs can live to be fifteen years old.狗能活15年。
（1）live on sth.意为“靠……为生”，这里的sth.常为表示“食物”的名词；live on sb.则表示“靠某人生活”。
Most Asians live on rice. 大多数亚洲人以大米为主食。
（2）live by...表示“靠……（手段）谋生”， by后通常跟表示方式、手段的动名词。
The old man lives by hunting. 这位老人靠捕猎为生。
3.Will people use money in 100 years
100年以后人们还使用钱吗？
in 100 years意为“在100年以后”，其中in为介词，其后跟一段时间表示“在……之后”，通常用于一般将来时，对其提问要用how soon（多久以后）。
I will come back in a week.我将在一周后回来。
in与for
in
for
表示以现在为起点的将来某一段时间之后
用how soon提问
表示某个动作或状态持续多长时间
用how long提问
4. There will be （more/less/fewer） people.
将会有（更多/更少/更少的）人。
more 是many 和 much 的比较级，意思为“更多的”，既可以修饰可数名词复数，也可以修饰不可数名词。
We need more time to finish the work.
我们需要更多的时间来完成这项工作。
（1）more 和多音节形容词或副词构成它们的比较级。
This movie is more exciting. 这部电影更刺激。
（2）“基数词+more+名词复数”相当于“another +基数词+名词复数”，意思是“再有……；还有……”。
I want to buy two more books.
=I want to buy another two books.
我想再买两本书。
（3）more than=over 超过。
More than /Over 10 persons lost their lives in the traffic accident. 超过10人在这次交通事故中丧生。
less 是little 的比较级，在数量上是more的反义词，意思是“较少的”，用于修饰不可数名词。
fewer 是few 的比较级，修饰可数名词复数，意思是“较少的”。

5.Everyone should play a part in saving the earth.
