Hi,

Carol.

Wow,

what

are

those?

Carol:

Hello,

Alex.

Oh,

these

are

some

of

the

interesting

inventions

that

I’m

writingabout

for

my

English

homework.

Alex:

I

see…What’s

that,

then?

Carol:

They’re

shoes

with

lights.

You

use

them

for

seeing

in

the

dark

when

you

get

up

at

night.

TapescriptsCarol:

Yes,

that’s

right!

The

last

invention

I’m

going

to

writeabout

is

shoes

with

special

heels.

You

can

move

the

heels

up

and

down.

Alex:

What

are

they

used

for?

Carol:

Well,

you

can

change

the

style

of

your

shoes.

You

can

raise

the

heels

if

you

are

going

to

a

party

or

lower

them

if

you

are

just

going

out

for

shopping.
