百年的时间。
Believe相信
①believe后可以直接接名词、代词做宾语。
I don’t believe you!我不相信你说的话。
②believe that从句〔后接否定的宾语从句时,通常将否定转移到主语句上。〕
I don’t believe that he will win.我相信他不会赢。
hundreds of 许多,大量
hundred面前有具体数次修饰时,不能加-s,如:one hundred,two hundred,
three hundred。表示概数时,hundred要加-s,后加介词of,即hundred of
“许多,大量,数以白计的”。
Hundreds of birds fly in the sky。 数百只鸟儿在空中飞翔。
There are two hundred good teachers in the school,so thousands of students are students are studying here。这所学校有200名优秀教师,因此成千上万的学生在此学习
拓展:
类似的搭配还有thousands of “数以千计的,成千上万的”,millions of“数以百万计的”。
Thousand of tourists come to visit the Great Wall every day.
每天都有成千上万的游客参观长城。
2.But scientist james White thinks that it will be difficult for a robot to do the same things as a person。但是科学家詹姆斯·怀特认为对机器人来说,像人一样做同样的事情是困难的。 句型:It is +adj.〔for sb.〕to do sth.“〔对某人来说〕做某事是…的”
It is +adj.+〔for ab.〕 to do sth.意为“〔对某人来说〕做某事是…的”。其中it是形式主语,to do sth.是真正的主语。如果要说明不定式表示的动作是谁做的,可以在不定式前面加一个由for引导的短语。
· It’s not good for old people to live alone.
对老人们来说独居是不好的。
·It’s really hard for me to work out the maths peoblem.
对我来说算出这道数学题确实很难。
扩展
It is+ adj.+ of sb. to do sth. 意为“做某事对于某人来说真是太…”。of 后应跟表示人性情或的形容词,如good, nice, kind, careful, clever等。
·It’s very nice of you to help me.你来帮助我,你真是太好了。
3.Mr. white that robots won’t be able to do this, but some scientists disagree.怀特先生认为机器人不会这样做,但是一些科学家不同意这种看法。
Be able to do sth. 意为“有能力做某事;会做某事”。
·He is able to swim . 他会游泳。
·We will be able to drive planes in ten years.
十年后我们就会开飞机了。
辨析 be able to 和 can二者都可以表示“能;会”。在表示现在和过去“力所能及”时,二者可以互换。

我现在会说一点英语。
·He was able to/could run fast when he was eight years old.
