2) Practise reading about the second paragraph paying attention to liasion and incomplete explosion. (This step can be chosen according to teaching needs.)
First introduce liaison and incomplete explosion:
Liasion(连读）--- 人们在流利交谈中，音素之间必然会产生连读现象。连读是快速语流的自然结果，也可以使语流更流畅、表达更得体。连读主要发生在一个词组内，有下列三大类：
1）词末辅音和词首元音连读。如：
put it on; take it off
2) 词末元音和词首元音连读。如：
go on; how old
3) 词末不发音的[r]和紧接其后的词的元音连读，
[r]必须发音。如： far away; for ever
Incomplete Explosion(不完全爆破)---爆破音是指发音器官在口腔中形成阻碍,然后气流冲破阻碍而发出的音。这些音有6个,即/p/, /b/, /t/, /d/, /k/和/g/。但在某些情况下,发爆破音时,气流不必冲破阻碍,而只是发音器官在口腔中形成阻碍,并稍做停顿,(也就是说,做好要发出这个爆破音的准备,但不要发出音来),这样的发音过程叫作“不完全爆破"。
不完全爆破的详细情况
1. 爆破音/p/, /b/, /t/, /d/, /k/, /g/在/t∫/, /d/, /W/, / /的前面时不完全爆破。如:
1) Have you rea(d) the book abou(t) tha(t)
child。
2) The thir(d) chair is broken.
2. 爆破音/p/, /b/, /t/, /d/, /k/, /g/在/m/, /n/, /l/, /s/的前面时不完全爆破。如:
1) Goo(d) morning, sir.
2) Goo(d) night.

Background Reading 背景阅读
Nowadays, when people refer to computer, Bill Gates perhaps is always the first person coming into your mind. He is generally regarded as the world’s most highly corporate chief.
William H. Gates
William (Bill) H. Gates is chairman and chief software architect of Microsoft Corporation, the worldwide leader in software, services and solutions that help people and businesses realize their ideas. Microsoft made US $36.84 billion for the fiscal year ending June 2004, and employed more than 55,000 people in 85 countries and regions.
Born on October 28th, 1955, Gates grew up in Seattle with his two sisters. Gates attended public elementary school and the private Lakeside School. There, he discovered his interest in software and began programming computers at the age of 13.
In 1973, Gates entered Harvard University as a freshman, where he lived near Steve Ballmer, now Microsoft’s chief executive officer. While at Harvard, Gates developed the programming language BASIC for the first microcomputer — the MITS Altair.
In his third year in university, Gates left Harvard to devote his energies to Microsoft, a company he had begun in 1975 with his childhood friend Paul Allen. Guided by a belief that the computer would be a valuable tool on every office desk and in every home, they began developing software for personal computers. Gates’ ideas and his vision for personal computers have been central to the success of Microsoft and the software industry.
Gates was married on January 1st, 1994, to Melinda French Gates. They have three children. Gates likes to read, and enjoys playing golf and bridge.

And I also look after their library. I store all the books that they borrow from their school or friends in my brain．Of course my brain is as large as a mountain, so work like that is no trouble to me．I really eat books just like people eat food．
The Lis have a child who is very spoiled. He needs me to remember all his school textbooks so that I can do his homework for him．He just gives me the information on the subject, what has to be done and the page numbers and I get on with it while he enjoys himself with his friends．Sometimes I don't think it is right to do his homework for him — it's somewhat cheating. However, his parents are very concerned at the pressure of work in school these days．The child has too much homework to do. They like him to go to the key school but they also want him to be able to have hobbies, learn to swim and keep fit! Poor child!
So they consider me the most important person in the family after themselves．I am always introduced to their friends and play with visiting children．I am the perfect family academic aid and, although I was not cheap to buy, Mr Li says I was worth every yuan!

First introduce liaison and incomplete explosion:
Liasion(连读）--- 人们在流利交谈中，音素之间必然会产生连读现象。连读是快速语流的自然结果，也可以使语流更流畅、表达更得体。连读主要发生在一个词组内，有下列三大类：
1）词末辅音和词首元音连读。如：
put it on; take it off
2) 词末元音和词首元音连读。如：
go on; how old
3) 词末不发音的[r]和紧接其后的词的元音连读，
[r]必须发音。如： far away; for ever
Incomplete Explosion(不完全爆破)---爆破音是指发音器官在口腔中形成阻碍,然后气流冲破阻碍而发出的音。这些音有6个,即/p/, /b/, /t/, /d/, /k/和/g/。但在某些情况下,发爆破音时,气流不必冲破阻碍,而只是发音器官在口腔中形成阻碍,并稍做停顿,(也就是说,做好要发出这个爆破音的准备,但不要发出音来),这样的发音过程叫作“不完全爆破"。
不完全爆破的详细情况
1. 爆破音/p/, /b/, /t/, /d/, /k/, /g/在/t∫/, /d/, /W/, / /的前面时不完全爆破。如:
1) Have you rea(d) the book abou(t) tha(t)
child。
2) The thir(d) chair is broken.
2. 爆破音/p/, /b/, /t/, /d/, /k/, /g/在/m/, /n/, /l/, /s/的前面时不完全爆破。如:
1) Goo(d) morning, sir.
2) Goo(d) night.
3) They are very frien(d)ly to us.
3. /p/, /b/, /t/, /d/, /k/, /g/这6个爆破音中的任何两个音素相邻时,前者发不完全爆破音,后者则要完全地。彻底地进行爆破。如:
1) He has a ba(d) col(d) today.
2) You shoul(d) ta(k)e care of the children.3) Gla(d) to meet you.
注意:不完全爆破可以发生在单词。短语或句子中。
Then get the students to read the second paragraph.
Sample:.
This year I ha（d）the honour to be chosen again．I wante（d）to meet robots from other countries and explore ideas about our sport．However, my programmer fell ill the wee（k）before we were going to leave．It was very painful for her and I fel（t）very frightened．I no longer fel（t）so

B : In my opinion, I agree with the point for the technology is developing faster and faster. I think they will kill people in the future.
G: They can’t develop beyond humans’ science development. And they can’t live without people. For example, if they are broken, they need to be repaired by people. Besides, they don’t fall in love with each other so they won’t get married. As a result, they have no babies. They will die out soon.
B: Although they are not able to give birth to a baby, they can copy themselves one after another.
G: But there is no evidence that can prove it.
B: However, many resources of the world will be used up soon. Then people can’t live on the earth. But robots are still alive.

Background Reading 背景阅读
Nowadays, when people refer to computer, Bill Gates perhaps is always the first person coming into your mind. He is generally regarded as the world’s most highly corporate chief.
William H. Gates
William (Bill) H. Gates is chairman and chief software architect of Microsoft Corporation, the worldwide leader in software, services and solutions that help people and businesses realize their ideas. Microsoft made US $36.84 billion for the fiscal year ending June 2004, and employed more than 55,000 people in 85 countries and regions.
Born on October 28th, 1955, Gates grew up in Seattle with his two sisters. Gates attended public elementary school and the private Lakeside School. There, he discovered his interest in software and began programming computers at the age of 13.
In 1973, Gates entered Harvard University as a freshman, where he lived near Steve Ballmer, now Microsoft’s chief executive officer. While at Harvard, Gates developed the programming language BASIC for the first microcomputer — the MITS Altair.
In his third year in university, Gates left Harvard to devote his energies to Microsoft, a company he had begun in 1975 with his childhood friend Paul Allen. Guided by a belief that the computer would be a valuable tool on every office desk and in every home, they began developing software for personal computers. Gates’ ideas and his vision for personal computers have been central to the success of Microsoft and the software industry.
Gates was married on January 1st, 1994, to Melinda French Gates. They have three children. Gates likes to read, and enjoys playing golf and bridge.
