On

today's

episode

of"Future

Changes",we

talkwith

two

experts

fromdifferent

fields,Dr

Han

and

Vincent

Black,to

hear

their

predictionsabout

thefuture.

First,Dr

Han,could

you

please

tell

our

audience

what

you

do?DrHan:

Certainly.I'm

a

computer

scientist.Host:And

could

you

please

tell

us

your

prediction?Dr

Han:Yes,well,I

forecast

thatcomputerswillbeclevererthanusinthe

future.I

thinkthatpeople

will

also

be

programmingcomputerstothinklikehumans.Host:That's

very

interesting,but

aren't

you

worried

that

such

computerswouldbe

dangerous?Dr

Han:Not

at

all.This

is

because

we'llbeprogrammingthem

to

not

think

in

ways

that

may

harm

humans.In

fact,we'll

also

be

creating

machines

to

help

peopleinternally.For

example,I

think

scientists

will

put

some

small

intelligent

machines,

callednanobots,insideourbodiesto

increase

our

abilities.Host:

Wow!That

would

make

each

one

of

us

superhuman!And

Vincent,could

youpleasetellusabout

yourjob?Vincent

Black:

Certainly.I'm

an

architect.I

design

buildings.Host:

And

what

is

your

prediction

about

the

buildings

of

the

future?Vincent

Black:It's

about

the

cities

of

the

future,actually.I

believe

that

cities

floatingonwaterarepartof

theworld's

future.Host:Oh,really?What

might

make

us

want

to

do

that?VincentBlack:Yes.Withglobalwarmingcausingpolaricetomelt,the

se

a

level

rising

by

many

metres

is

a

very

realistic

prospect.Instead

of

moving

people

away

from

thesea,I

think

that

people

could

move

into

housing

in

cities

that

float.Host:That

sounds

very

innovative.Could

you

please

give

us

more

details?Vincent

Black:

Sure.Well,I've

developed

a

plan

by

designing

a

city

that

borrowsmany

ideas

from

the

giant

water

lily,a

flower

that

floats

on

water.Moreover

..Post

listening1.Work

in

pairs,and

discuss

whether

Dr

Han

and

Vincent

Black's

predictions

are

possible

and

why

or

why

not?I

think

Dr

Han's

prediction

is

impossible.Computers

can

never

be

clevererthan

us.Because

they

are

programmed

by

humans.I

think

Vincent

Black's

predication

is

likely

to

happen,because

ofglobalwarming,the

sea

level

is

rising.Some

places

will

be

flooded

and

the

land

is

getting

smaller.Hence,it

is

a

good

idea

to

build

houses

above

the

sea.Tips1.Write
