Revision

T：Boys

girls，in

last

period

we

learned

something

about

the

history

and

development

of

computers.Now

who

would

like

to

retell

text

with

help

of

these

figures?

S1：Let

me

try.In

1642，a

calculating

machine

was

used

in

France.Then

in

1922，the

Analytical

Machine

was

made

by

Charles

Babbage.It

could

follow

instructions

from

cards

with

holes.In

1936，Alan

Turing，the

real

father

of

computers，wrote

a

book

to

describe

how

computers

could

be

made

to

work

and

built

a

“universal

machine”

to

solve

any

mathematical

problem.Later，people

discovered

the

computer

had

“artificial

intelligence”.In

the

1960s，the

computer

got

his

new

transistors.Its

size

was

totally

changes

at

that

time.And

in

the

early

1960s，the

first

family

of

computers

were

connected

to

each

other.In

1970s，computers

have

brought

into

people’s

homes.Now

computers

have

been

used

by

billions

of

people

to

deal

with

information

and

communicate

with

each

other

around

the

world

by

the

Internet.
