Work in pairs. Imagine you are tw
o inventors and you have designed
a new product,which you want to s
ell.
Talking on P55
First, you need to decide on your
product; Second, you will have to
explain how your product works.
Third, you need to show that people will
be willing to use it.
Use the descriptions on P56.
ZH: I understand you have invented
something that will be really useful
to families and single people alike.
Sample talking
XG: Yes, indeed. It’s a self-cleaning
shirt, which works as you wear it.
We made one that would work as
soon as you put it on. It uses the
heat from your body to attract
water vapor from the air.
ZH: Isn’t that a little uncomfortable?
XG: No. We thought about that. We ga
ve the material a special coating to
keep water away from the skin an
d to store it in the fibres. When th
ey are full of water the shirt begin
s to clean itself.
ZH: How does it do that? Is there soap
powder in the fibres too?
XG: Not really, but we thought the fibres could do that job if they had a special anti-pollutant in them. It mixes with the water and removes the dirt from the shirt. The dirt is then carried into the air as the water turns back into vapor.
ZH: How will you know if the shirt is doing its job?
XG: If the shirt is working well it will appe
ar white. When the shirt is blue, it’ll
mean the shirt is too old and isn’t wor
king properly. It’ll also mean it’s time
to throw it away. We think all our shi
rts should be able to deal with any lev
el of water vapor in the atmosphere.
ZH: Well, that seems clear.Will it come i
n other colours as well as white?
XG: We hope so. I’m working on shirts t
hat will do the same job but are gre
en, brown, beige and golden. We ho
pe to be able to bring them all onto
the market next year.
ZH: They sound the colours for me. I’
m afraid white doesn’t really suit
me. It makes me look ill.
XG: I’m sorry about that as I planned
to give you one as a gift. I wanted
you to try it and tell your listeners
what you think.
ZH: Well, I’m sure I could make
exception just this once. I’d really
like to give one a try. Thank you.
XG: And thank you for being so
positive about it. I hope you have
good things to tell me soon.
ZH: So do I. Goodbye.
XG: Goodbye.
In our group, we invent a new kind of
wall for the future. Nowadays we can see
walls all round us. These walls have grea
tly limited our sight, our life and the rela
tionship among people as well. In contra
st to the “old”walls, you can not see or ev
en feel the existence of our walls.
A Sample writing:
People live freely in the world! If you
don’t want others to see some part of th
e house, the wall can covered it just as if
it’s part of the nature! Someone may be
worried, does that mean anyone can co
me into my house?
No, the wall can sense your credit
which permits you to come into the
house. You don’t have to use a key and
you don’t need to be worried about
your house being broken into.

Homework
1. Finish Exercise1, P19.
Exercise4,P57.
2. Imagine you are your age of 30. Write
a passage to describe your daily life or
your experience.
Sample
It is the year 2020 and I have just
turned 30 years old. More than 10 years
age. I left high school and went to study
at a good university. I was a history
major and I also offered a job teaching
history in a middle school.
I thought the students would think
history was too boring. My first year
was very difficult. I didn’t know much
about teaching and the students did
not like my lessons. But I was lucky.
One of the older teachers became my
friend and taught me a lot.
