[命题点一]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.然而,有的科学家相信尽管我们可以使机器人像人一样移动,但是使它们真的像人类一样思考是困难的。 　
◎观察思考:1.It's not good for old people to live alone. 对老人们来说,独居是不好的。
2.It's really hard for me to work out the math problem.对我来说,算出这道数学题确实很难。
◎用法总结:It is +adj.+(for sb.) to do sth.意为“(对某人来说)做某事是……的”。其中it是形式主义,to do sth.是真正的主语。
【拓展】It is + adj. + of sb. to do sth.意为“做某事对于某人来说是……”。of后应跟表示人的性格或品质的形容词。如good, nice, kind, careful, clever等。如:
It's very nice of you to help me.你能帮助我真是太好了。

[命题点二]However, they agree it may take hundreds of years. 然而,他们一致认为那可能会需要数百年的时间。
◎观察思考:1.There are hundreds of people in the restaurant. 在餐馆里有成百上千的人。
2.There are nine hundred students in our school. 我们学校有900名学生。
◎用法总结:hundreds of意为“数百,数以百计的”。
hundred前面有具体数字修饰时,词尾不能加“s”,例如:one hundred、two hundred、three hundred。表示概数时,hundred词尾要加“s”,后加介词of,即hundreds of,意为“数百;数以百计的”。
【拓展】这类表示数字的词还有thousand“千”、million“百万”、billion“十亿”。它们的用法和hundred一样。
◎观察思考:1.It takes me two hours to finish the work.完成这项工作花了我两个小时。
2.It takes me half an hour to get to school.我花了半个小时到学校。
◎用法总结:take意为“花费”。
It takes sb. some time to do sth. 意为“做某事花费了某人多长时间”。
