The oldest person I know is an old woman who is 95 years old now. She  lives in my neighborhood and I often have a talk with her. At such an old  age, she can still see and hear quite well. Every day she comes out and takes  a walk so long as the weather is fine. And she also has a habit of doing  massage by herself. She told me that until she was in her eighties she still  kept practicing Shadow Boxing, a traditional Chinese way of physical  exercise. So I think regular exercise must be one of the main reasons why she  can enjoy such a long life.

A  developed country  refers to  an industrialized nation with a robust economy and infrastructure.

A  developing country  is still  working on being industrialized.

An  undeveloped country  is  almost completely not industrialized.

How  long can humans live? In most developed countries, people are now living an  average of 75 years. But scientists are trying to find ways to lengthen our  lives— perhaps to 120 years or older—and to help us remain young as we age.

To  do this, scientists are studying special groups of people around the world.  These people seem to be immune to certain diseases that shorten our lives.  Some Ecuadorians, for example, have a gene that seems to prevent dangerous  diseases like cancer and diabetes. Japanese American men also seem to have a  special gene that lowers their chance of getting cancer and heart disease.  Learning how these genes work could help extend life  for us all and keep us healthier, too.

To disagree respectfully, the speakers in the  audio say:

Well, I just don’t know;

I know what you mean, but ...;

That’s a good point, but ...

The language introduced in Important language  includes:

Really? I completely disagree. For one thing ...;  I know what you mean, but ...; I know what you’re saying, but ...

Note that Really? I completely disagree. For one  thing ... is more direct than the other expressions.

Additional useful language for disagreeing  includes:

I understand your point, but ...;

I see what you’re saying, but ...;

That’s interesting, but ...

The picture on page 81 shows the first cloned cat  in the world. CC, which stands for Copy Cat, was cloned in 2002 and is still  alive today. She lives with one of the scientists who helped make her. CC has  had kittens, making her the first cloned animal to give birth. While other  cloned animals have commonly developed health problems, CC has had a healthy  life so far.

On the one hand, the ears don't require all of the  blood vessels that the rest of the organs in the human body require.  Therefore the ear is one of the easier organs to start with .On the other  hand, ears have a complicated shape. The first step is to create a shape that  looks real. Special wire is needed to make the metal support structure for a  scaffold. Also, it's important to create the inner part of the ear correctly  so that hearing will be possible. Therefore the ear is not a simple organ to  start with

Language Note

The words scaffold and scaffolding refer to  something that gives structure and support to something else. Both words are  commonly used to describe the framework that is put up around a building  during construction. In the picture on page 80 and in the video, the word  scaffold is used to explain what's being made to help the artificial ear  maintain its shape. The scientist in the video is making a scaffold out of  metal to support the ear's shape. It is the first step in making the  artificial ear.

Listening for agreement and  disagreement

   a variety  of expressions for expressing agreement and disagreement have been

introduced. Apart from these expressions which are  usually used on formal occasions, you can tell Ss that there are some other  expressions which can be used in other situations. For example, You can say  it again and You are telling me are colloquial expressions which can be used  to express agreement in informal situations. Expressions like Not at all,  Nothing of the kind, and On the contrary are direct and abrupt ways of disagreement,  and Nonsense, Rubbish, No way, (That's) ridiculous are very abrupt and even  rude expressions of disagreement

When  listening for agreement and disagreement, you can also ask Ss to pay  attention to the following expressions, which are usually followed by  expressions showing agreement or disagreement.

Asking for  an opinion

What's your idea?

How do you feel about that?

Do you have anything to say about  this?

What do you think?

Do you agree?

Interrupting

Can l add  something here?

Is it OK if  l jump in for a second?

If l might  add something …..

The way l se  it..

If you want  my honest opinion...

As far as  I'm concerned...

Intonation is another tool speakers can use to  indicate their attitudes. It is useful to recognize common intonation  patterns because people do not always express their true attitudes or  feelings through their words alone. You can introduce the following  generalization to Ss so that they make use of the speaker's intonation and  tones of voice to make inferences about how strongly the speaker agrees or  disagrees.

Reference

Well, I just don’t know  ...

I know what you mean, but  ...

That’s a good point, but  ...

Really? I completely  disagree. For one thing ...

I know what you mean, but  ...

I know what you’re saying,  but ...

I understand your point,  but ...

I see what you’re saying,  but ...
