相关话题——阅读理解。Alfredo

Moser

is

a

Brazilian

worker

who

is

skilled

at

repairing

machines.

His

wife

says

her

husband

has

always

been

handy(手巧的)at

home

and

made

tables

and

chairs.

Alfredo

has

invented

a

way

of

lighting

his

house

during

the

day

without

electricity.He

has

been

using

plastic

bottles

filled

up

with

water

and

a

little

bleach(漂白剂)to

provide

dark

rooms

with

light

for

many

years.

And

the

idea

has

now

spread

across

the

world.

It

is

predicted

that

his

lighting

system,which

works

using

refraction(折射)of

sunlight,will

be

fitted

in

over

a

million

homes

by

the

end

of

this

year.

Alfredo

used

normal

plastic

drinks

bottles

that

are

often

thrown

away.

The

secret

of

the

liquid

in

the

bottles

is

the

bleach

added

to

water,which

stops

it

turning

green

in

the

sunlight.

Mr.

Moser

drills

a

hole

in

a

roof

tile(在屋瓦上钻洞)and

then

pushes

the

bottle

in

from

below,keeping

the

bottle

in

place

with

polyester

resin(聚酯树脂).

Depending

on

the

strength

of

sunlight,the

light

fills

his

home,and

the

bottles

are

just

like

electric

bulbs

of

between

40

and

60

watts(瓦特)．Alfredo

came

up

with

the

idea

for

his

“Moser

light”

during

one

of

the

blackouts

in

Brazil

in

2002.

He

said

only

factories

had

power

in

his

home

city,in

southern

Brazil

during

the

energy

shortage.The

local

supermarket

and

his

neighbors'

houses

are

utilizing

Moser

lights.

He

earned

a

few

dollars,but

his

invention

has

not

made

him

a

r
