Will ... in 100 years
Yes, …will./ No, ...won’t.
1. Do you think there will be robots in people’s homes
there will be 意为“将会有……”，是there be句型的一般将来时结构，可与there is/are going to be...进行句式转换。
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。
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”。
（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”。
（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。
3. Will people use money in 100 years
100年以后人们还使用钱吗？
in 100 years “在100年以后”，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）。
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，“更多的”，既可以修饰可数名词复数，也可以修饰不可数名词。
