阅读理解。（2023宜春丰城中学期末）

Plastic

pollution

has

become

a

serious

problem

in

Kenya.

Instead

of

sitting

around

and

waiting

for

the

government

to

solve

all

the

problems

with

plastic

pollution,

a

woman

decided

to

take

action.

Nzambi

Matee,

a

material

engineer,

started

Gjenge

Makers

Ltd.

in

Nairobi,

Kenya.

The

company

collects

plastic

waste

and

uses

it

to

create

bricks

that

are

seven

times

as

strong

as

concrete

（混凝土）

but

weigh

half

as

much.

Even

better,

the

bricks

are

cheaper

than

traditional

bricks,

costing

only

about

a

tenth

as

much.

These

special

bricks

are

being

used

to

make

driveways,

sidewalks

and

roads,

but

Nzambi’s

goal

is

to

create

some

that

can

be

used

in

buildings

one

day.

In

fact,

her

company

is

already

making

a

huge

difference.

“

We

right

now

can

produce

1,

000

to

1,

500

bricks

a

day,

”

Nzambi

said.

“So

far

we

have

recycled

over

20

tons

of

plastic

waste,

and

we

are

looking

to

push

that

to

50

tons.”

While

part

of

Gjenge

Makers’

goal

is

to

reduce

plastic

pollution

first

in

Kenya

and

then

in

Africa

as

a

whole,their

long-term

goal

is

greater.

According

to

Nzambi,

they

want

to

encourage

other

people,

especially

the

youth,

to

do

similar

things

in

different

places.

Achieving

the

goals

won’t

be

easy.

In

fact,

just

starting

a

company

with

such

great

dreams

was

hard.But

rather

than

waiting

until

she

felt

completely

ready,

Nzambi

simply

got

started.

"Isn’t

that

how

great

things

are

done?

she

said.21.What

are

the

advantages

of

Nzambi’s

bricks?

___BA.Big,

strong

cheap.

B.Strong,
