Do You Think You Will Have Your Own Robot
1. When we watch movies about the future, we sometimes see robots. They are usually like human servants. They help with the housework and do jobs like working in dirty or dangerous places.
2. Today there are already robots working in factories. Some can help to build cars, and they do simple jobs over and over again. Fewer people will do such jobs in the future because they are boring, but robots will never get bored.
3. Scientists are now trying to make robots look like humans and do the same things as we do. Some robots in Japan can walk and dance. They are fun to watch. However, some scientists believe that although we can make robots move like people, it will be difficult to make them really think like a human. For example, scientist James White thinks that robots will never be able to wake up and know where they are. But many scientists disagree with Mr. White. They think that robots will even be able to talk like humans in 25 to 50 years.
4. Some scientists believe that there will be more robots in the future. However, they agree it may take hundreds of years. These new robots will have many different shapes. Some will look like humans, and others might look like animals.
In India, for example, scientists made robots that look like snakes. If buildings fall down with people inside, these snake robots can help look for people under the buildings. This was not possible 20 years ago, but computers and rockets also seemed impossible 100 years ago. We never know what will happen in the future!

1. ①Will robots think like humans in the future
②They are usually like human servants.
Language points
human adj. 人的；n. 人；人类
第一句中human作名词，意为“人；人类”，与human being 意思相同。 第二句中human作形容词，意为“人的；人类的”。
Dogs can hear much better than humans.
The noise comes from a number of human activities.
2. Today there are already robots working in factories.
There be sb./sth. doing sth.
有某人/某物正在做某事
There is a girl singing in the next room.
There are two cats sleeping in the sun.
3. … and they do simple jobs over and over again.
over and over again 多次；反复地；再三
此短语中的again可以省略。
比较over and over again与(all) over again:
over and over again 反复地 I’ll do it over and over again. 我会反复做这件事。
(all) over again 从头再来 I’ll do it (all) over again. 我会重新做这件事
4. However, some scientists believe that although we can …
believe v. 相信；认为有可能
（1）believe在此作及物动词，一般不用于进行时态。 其后常跟名词，代词或从句作宾语。
Believe it or not, your brain never stops working.
I believe that an apple a day keeps the doctor away.
believe 表示相信某人的话，相信某事等。 We don’t believe in her, so we don’t believe what she says.
我们不信任她，所以我们不相信她说的话。
believe in 表示“信任；信仰”，多指品德、操守等方面可靠、可信。
易混辨析
5. … that robots will never be able to wake up and know where they are.
wake up 醒来；叫醒
（1）wake up在此处用作不及物动词短语。
They wake up every morning to work for their families and their future.
（2）wake up还可作及物动词短语，此时为“动词+副词” 型短语，后接名词作宾语时，名词放在up前或后均可；后接代词作宾语时，代词只能放在wake与up之间。
Don’t wake up your sister, Ben.=Don’t wake your sister up, Ben.
It’s 7 o’clock. It’s time to wake him up.
6. ①But many scientists disagree with Mr. White.
②However, they agree it may take hundreds of years.
disagree v. 不同意；有分歧 agree v. 同意；赞成；应允
disagree与agree互为反义词，其用法相似，以agree为例：
agree with sb./sth. 同意某人的看法或观点，后接人或表示“意见；看法”的名词
agree to sth. 同意（计划，建议，安排等）
agree to do sth. 同意做某事
agree on sth. 就……取得一致意见
agree + that从句 赞成……；同意……

Most people agree that the novel is a good one.
①But many scientists disagree with Mr. White.
②However, they agree it may take hundreds of years.
disagree v. 不同意；有分歧 agree v. 同意；赞成；应允
7. However, they agree it may take hundreds of years.
hundreds of 许多；大量
hundred 表示具体数量，意为 “百”。其前有a，several及具体数字时，hundred后不加-s，也不和of连用。 The reading room can hold two hundred people.
hundreds of 表示笼统的数量，意为“许多；大量”。不可与具体数字连用。 He has hundreds of books.
模糊数字“两有”（有-s有of), 具体数字“两无”（无-s无of）。
8. They think that robots will even be able to talk like humans in 25 to 50 years.
even adv. 甚至；连；愈加
（1）even位置比较灵活，常置于所修饰的词前，用来加强语气。
It’s cold there even in summer.
Even Tom, a little boy, knows it.
（2）even可放在形容词、副词的比较级前， 修饰比较级，表示程度。
The computer could play chess even better than humans.
fall down 突然倒下；跌倒；倒塌
（1）fall（过去式为fell）在此作动词。
Babies often fall down when they learn to walk.
（2）fall还可作名词，其用法有;
9. If buildings fall down with people inside, these snake robots can help look for people under the buildings.
