What can robots do
Language point
Do You Think You Will Have Your Own Robot
When we watch movies about the future, we sometimes see robots. Theyare usually like human servants. They help with the housework and do jobs like working in dirty or dangerous places.
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.
factory----factories 工厂
help sb. with sth.
帮助（做）某事
help sb. (to) do sth.
帮助做某事
get + 形容词
变得；觉得
其同义词为：be bored
二者的区别在于：
get bored（强调动作）
be bored （强调状态）
there be sb. doing sth. 某地有某人正在做某事
2b
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.
try to do sth. 尽力去做某事 try doing sth. 尝试做某事
make sb. / sth. do…使某人/某物做......
be able to 和 can 的区别
(1) be able to 用于表能力，并可用于多种时态和非谓语动词短语，而can 只有一般现在时和一般过去时两种时态。
(2) can 可用于人或物作主语的句子中；而be able to 的主语只能由有生命的名词充当。
(3) can 常指客观上能够；be able to 更侧重于“克服一定困难”、“经过努力”、“有能力”做成某事。
disagree/agree with sb/sth
不同意/同意某人/某事
agree/disagree to do sth.
同意/不同意做某事
be able to do sth.
能够做某事
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!
hundreds of 许多；大量
hundred 数词, “百”, 用于a，one或含有数量意义的词之后, 其后接可数名词的复数形式。如：one hundred student
当这类数词前面有具体的数字时, 数词不能用复数形式。如:three hundred
类似的数词还有thousand , million, 当数词前没有具体数字时, 数词用复数形式, 后面接短语, 再加可数名词的复数形式。

3. Some can _________ and _____________.

然后，根据2b中短文的内容填空。
2d

What kind of animals might robots look like in the future What do you think these robots will be able to do Write your ideas and discuss them with your partner.
2e
I think some future robots might look like
spiders. They will be able to help us clean the window, sweep the floor.
Some robots might look like snakes. They will be able to help look for people under the buildings. If buildings fall down with people inside.
They will also be able to sever us. They can make dinner, do the dishes and cook coffee for us.
Some robots will be look like people. They will be able to sing, dance and talk with us.
Some robots might look like big arms. They will be able to work in factories. They can help make cars and do simple jobs over and over again.
Today there are already robots working in factories. 现在已经有机器人在工厂里干活了。
此句中的working in factories的逻辑主语是robots，但是在这个there be句型中，谓语动词已经有了are，所以work就不能再作本句的谓语动词，而应用-ing形式。可以理解成working in factories 是robots的后置定语，这一点在学习和使用there be句型时需要特别注意。
