二、例句解析。
1.Some scientists believe that there will be more robots in the future. However, they agree it may take hundreds of years.
一些科学家相信将来会有更多的机器人，然而，他们都认为这要经历上百年的时间。
(1)however意为“然而，可是”，可与although/though转换，但however更正式一些，一般用逗号和句子隔开。
Eg: Everyone played well, However, we still lost the game.
(2)take花费，常构成词组It takes sb sometime to do sth.
Eg: It took me twenty minutes to do the housework.
2.But scientist James white thinks it will be difficult for a robot to do the same things as a person.
但是科学家詹姆森·怀特认为对于一个机器人来说要像人一样做同样的事情将是很困难的。
(1)本句含有一个以that引导的宾语从句，宾语从句中使用了“it will be+形容词+for sb+to do sth”结构，这里it作形式主语，代替真正的主语to do the same things as a person.
Eg: It is difficult for me to finish the job in a week.
(2)it还可以放在feel, think,
find后作形式宾语，真正的宾语是后面的动词不定式。
Eg: I find it easy to work out the math project.
(3)the same as和…一样的，same前常用定冠词the，此处as a person后省略了does.
Eg:Lucy likes wearing the same clothes as I do.
3.That may not seem possible now, but computers and rockets seemed impossibe 100 years ago.
这在现在看来不太可能，但是电脑和火箭在一百年前也似乎是不可能的。
(1)possible“可能的”常构成词组as…as possible,意为“尽可能…”，相当于as…as sb can.
impossible“不可能的”和possible为反义词。
Eg: It’s impossible for him to learn English well.
(2)seem似乎，像是，常用结构：seem+adj, seem to do sth, It seems that+从句。
Eg: He seems smart.
He seems to be a teacher.
It seems that he is angry.
(3)look和seem都为看起来，look看起来似乎如此，seem指事实上似乎是那样的，暗示判断有一定根据，接近现实。
Eg:He looks old, but he seems to be much younger in red.
4. We never know what will happen in the future!
我们永远不知道未来会发生什么。
(1)happen常指具体事件的发生，多指偶然的或未能预测到的“发生”，常构成词组sth happen(s) to sb意为“某人发生某事”。
Eg: What happened to Bob?
(2)take place通常指某事按计划进行或发生。
Eg: The accident took place only a block from his home.
