What

will

our

life

be

like

in

50

years?

No

one

knows

the

answer,

but

we

are

sure

that

it

will

be

very

different

from

the

life

today.

My

brother

Jill

White

makes

some

predictions.

Here

are

some

of

his

ideas.

First,

people

will

have

less

work

to

do,

and

robots

will

do

most

work.

People

will

use

robots

to

make

cars,

do

the

housework,

look

after

sick

people

and

teach

students.

People

will

spend

most

of

their

time

playing

sports

and

traveling,

so

they

will

bee

stronger

and

healthier,

and

they

will

live

to

be

about

200

years

old.

Second,

cars

will

bee

very

small

and

puters

will

control(控制)their

speed(速度).

So

there

will

be

fewer

accidents(事故)

on

the

road.

Planes

will

be

very

popular

and

most

people

would

like

to

take

them

to

travel.

Third,

people

will

be

able

to

live

in

the

sea,

on

the

moon

or

on

Mars.

The

earth

won't

be

crowded

or

noisy.

So

there

will

be

much

space

for

people

to

plant

trees.

There

will

be

less

pollution,

and

the

air

will

bee

much

fresher.

Finally,water

shortage

will

bee

one

of

the

most

serious

problems.If

people

don't

save

water

now,

we

will

have

no

water

to

drink

in

50

years.
