A sample:

Sunny Wednesday

I am very happy today,because this is the first day that I has spent with my owner,Susan.Susan is a 6-year-old sick girl.She cannot go out with other children because of her poor health.So her parents bought me as her companion.There are different types of robot pets in the store.Her mom preferred the seal-type robot,while her dad thought the lovely dog would be a good companion.But Susan loves kitty very much.She insisted on having me as her companion.So they chose me.

The shop assistant told them I have more than just entertainment value,offering companionship and a variety of other services to the sick.A network system will enable me to speak to the children in a natural way,especially to children who are sick,and this will make them more comfortable.

I can be connected via cell phone or ISDN line to a network system center,allowing health workers or parents to send medical information and encouraging messages to the sick.I'm

endowed with 100 phrases,ranging from the light-hearted (“Today is the karaoke party.Let's sing a lot.”) to more practical information (“It is three o'clock.It is time to have medicine.”).

Susan smiled a lot and her parents said she has never spent a happier day.I am happy too because I've brought pleasure to her.

3.It was when Asimov was elev en years old that his talent for writing became obvious.

4.It was disturbing and frightening that he looked so human.

机器人如此通人性,这使她觉得心烦和害怕。

It是形式主语,that引导的句子是这个句子的主语,that从句叫主语从句。It放在句首,真正的主语放在后面,这是英语的一种常见结构。

It was clear that Claire had fallen in love with Tony.

很显然,克莱尔已爱上了托尼。

It seems unlikely that she will refuse the offer.

看上去她不太可能拒绝给她的帮助。

带有that从句的先行词结构有以下几种不同的搭配关系:

(1)It+be+adj.+that clause.

It is certain that William will do well in his exam.

威廉肯定会考得很好。

It is absurd that he believes the number 13 has brought him the bad luck.

他认为是13这个数字给他带来了厄运,这太可笑了。

在表示建议、命令、要求等意义的It结构中,that从句的谓语动词常常用(should)+do 的形式。

It is said that he (should) go there without delay.

他最好马上去那里。

It is important that we (should) be here by the weekend.

周末我们得在这里,这很重要。

在表示惊讶、喜悦、遗憾等意义的It结构中,that从句的谓语动词也常用这种形式。It isn't amazing that they should have decided to divorce.

他们已经决定离婚,这并不令人吃惊。

It is regrettable that Tom should leave so soon.

真遗憾汤姆这么快就要离开了。

(2)It+be+n.(or noun phrase)+that clause.

It is a great pleasure that she is well again and can go to her office.

她身体恢复了,可以去上班了,这真让人高兴。

It is a pity that she should refuse to accept this suggestion.

真遗憾她拒绝了这个建议。

(3)It+be+v.-ed+that clause.

It is said that Isaac will accompany his parents to visit Europe.

据说艾莎克将陪父母去欧洲访问。

It is suggested that each children should sing a song in English at the party.

建议每个学生都得在晚会上唱支英文歌。

(4)It seems/happens...+that clause.

It seems that they are in urgent need of help.

好像他们现在急需帮助。

It happens that the prettiest birds are the worst singers.

很碰巧,最漂亮的鸟是最差的歌手。

要注意的是这种结构与强调结构的区别。试比较:

It was Tony that managed to help her in time.

是托尼及时设法帮助了她。

It was then that Claire realized that Tony had opened the curtains of the front window.

也就在这时候,克莱尔才意识到托尼早就把前边窗户的窗帘拉开了。

5.So Claire borrowed a pile of books from the library for him to read,or rather,scan. 于是,克莱尔从图书馆借了一堆书给托尼阅读,或者说给他浏览一下。

(1)a pile of/piles of=a lot of

There were a pile of magazines on the desk.

桌子上有一堆杂志。

I've got piles of work to do this evening.

今天晚上我有一大堆工作要做。

(2)or rather:a way of correcting something you have said,or making it more exact.

He lives in London,or rather,in the suburbs of London.

他住在伦敦,更准确地说是在伦敦郊区。

You have to be sixteen for cheap tickets—or rather under sixteen.

你得是16岁才能买便宜的票,更准确地说是16岁以下。

6....you cannot have women falling in love with machines.

……总不能让女人爱上机器。

这句话的结构是have+n.+doing,have的意思是cause sb.to do,它与have+sb.+do结

构的意思有时略有不同,前者讲的是过程,后者叙述的是当时的情况。

As soon as I got there,I tried to have John find me a house.

我一到那里,就试着让约翰给我找房子。

S he had us all laughing at her jokes.

她的笑话让我们大笑。

另外,在have+n.+doing结构中,如果have用作否定时,其意思是not permit or allow。

I can't have you going everywhere and doing nothing all day.

我不能让你整天无所事事地东游西逛。

7.Asimov had both an extraordinary imagination that gave him the ability to explore future worlds and an amazing mind with which he searched for explanations of everything,in the present and the past.

阿西默夫不仅有超凡的想象力,使他能对未来世界进行探索,而且还有着惊人的智力,使他对现在的和过去的各种事物作出解释。

这个句子稍微有点复杂,现简要地分析一下:Asimov had both an extraordinary imagination and an amazing mind是这个句子的重要部分,动词不定式to explore future worlds 修饰ability,with which引导的定语从句修饰an amazing mind。

with which是“介词+which (whom)”的结构,其介词的选择受到一定的限制:或与前面的名词搭配有关(本句就是这样),或与后面的动词或者词组搭配有关。

He seemed to be looking for the words with which he could express what he was thinking about.

他好像正在找能表达他想法的词语。

The car,for which I paid a lot of money,is now out of date.

我花很多钱买的这辆小汽车现在过时了。

二、文化背景知识

Robot

A robot can be defined as a programmable,self-controlled device consisting of electronic,electrical,or mechanical units.More generally,it is a machine that functions in place of a living agent.Robots are especially desirable for certain work functions because,unlike humans,they never get tired;they can endure physical conditions that are uncomfortable or even dangerous;they can operate in airless conditions;they do not get bored by repetition;and they cannot be distracted from the task at hand.

The concept of robots is a very old one yet the actual word “robot” was invented in the 20th century from the Czechoslovakian word robot or robotic meaning slave,servant,or forced labor.Robots don't have to look or act like humans but they do need to be flexible so they can perform different tasks.

Early industrial robots handled radioactive material in atomic labs and were called master/sl ave manipulators.They were connected together with mechanical linkages and steel cables.Remote arm manipulators can now be moved by push buttons,switches or jo ysticks.

Current robots have advanced sensory systems that process information and appear to function as if they have brains.Their “brain”is actually a form of computerized artificial intelligence (AI).AI allo ws a robot to perceive conditions and decide upon a course of action based on those conditions.

A robot can include any of the following components:

effectors—“arms”,“legs”,“hands”,“feet”

sensors—parts that act like senses and can detect objects or things like heat and light and convert the object information into symbols that computers understand

computer—the brain that contains instructions called algorithms to control the robot

equipment—this includes tools and mechanical fixtures

Characteristics that make robots different from regular machinery are that robots usually function by themselves,are sensitive to their environment,adapt to variations in the environment or to errors in prior performance,are task-oriented and often have the ability to try different methods to accomplish a task.

Robot Timeline

270BC an ancient Greek engineer named Ctesibus made organs and water clocks with movable figures.

1942—Asimov wrote “Runaround”,a story about robots which contained the “Three Laws of Robotics”:

A robot may not injure a human,or,through inaction,allow a human being to come to harm.

A robot must obey the orders by human beings except where such orders would conflict with the First Law.

A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

1948—“Cybernetics”,an influence on artificial intelligence research was published by Norbert Wiener.

1956—George Devol and Joseph Engelberger formed the world's first robot company.

1959—Computer-assisted manufacturing was demonstrated at the Servomechanisms Lab at MIT.

1961—The first industrial robot was online in a General Motors automobile factory in New Jersey.It was called UNIMATE.

1963—The first artificial robotic arm to be controlled by a computer was designed.The Rancho Arm was designed as a tool for the handicapped and its six joints gave it the flexibility of a human arm.

1965—DENDRAL was the first expert system or program designed to execute the accumulated knowledge of subject experts.

1968—The octopus-like Tentacle Arm was developed by Marvin Minsky.

1969—The Stanford Arm was the first electrically powered,computer-controlled robot arm.

1970—Shakey was introduced as the first mobile robot controlled by artificial intelligence.It was produced by SRI International.

1974—A robotic arm (the Silver Arm) that performed small-parts assembly using feedback from touch and pressure sensors was designed.

a computer.The computer analyzed the distance between the cart and the obstacles.
