On

a

boat

near

Costa

Rica,

a

team

of

marine

biologists

is

helping

a

turtle.

The

animal

is

having

trouble

breathing,

and

the

team

discovers

why-there

is

something

inside

its

nose.

A

scientist

tries

to

extract.

.the

object,

but

the

turtle

cries

in

pain.

Finally,

after

another

eight

minutes,

a

long

object

turns

up

and

is

seen

clearly:

it

is

a

10-centimeter

plastic

straw.

The

video

of

the

turtle’s

rescue

has

been

viewed

millions

of

times

on

YouTube.

It

has

helped

raise

awareness

of

a

growing

problem:

The

world’s

seas

are

full

of

plastic.

Since

2000,

there

has

been

a

huge

increase

in

worldwide

plastic

production,

but

we

recycle

less

than

one-fifth

of

it.

A

lot

of

this

plastic

waste

ends

up

in

the

ocean.

Today,

scientists

think

about

8.1

billion

kilograms

goes

into

the

sea

every

year

from

coastal

regions.

Most

of

this

plastic

will

never

biodegrade,

or

they

will

take

hundreds

of

years

to

biodegrade,

which

can

be

harmful

to

the

environment.

This

ocean

plastic

hurts

millions

of

sea

animals

every

year.

Some

fish

eat

plastic

because

it

is

covered

with

sea

plants,

and

it

looks

and

smells

like

food.

Typically,

eating

plastic

leads

to

constant

hunger.

“Imagine

you

ate

lunch

and

then

just

felt

weak.

and

hungry

all

day,

”

says

marine

biologist

Matthew

Savoca.

“That

would

be

very

confusing.

In

some

cases,

eating

sharp

pieces

of

plastic

can

seriously

hurt

sea

animals

and

even

result

in

death.

Plastic

is

useful

to

people

because

it

is

strong

and

lasts

a

long

time-but

this

is

bad

news

for

sea

creatures

who

eat

or

get

stuck

in

it.

In

light

of

Savoca,

”Single-use

plastics

are

the

worst.

These

are

items

that

are

used

onlyonce

before

we

throw

them

away.

Some

common

examples

include

straws,

water

bottles,and

plastic

bags.About

700

sea

species

（including

the

turtle

from

the

video）have

been

caught

in

or

have

eaten

this

kind

of

plastic.Luckily,

the

turtle

survived

and

was

released

back

into

the

ocean.

How

will

plastic

affect

sea

animals

in

the

long

term?“

I

think

we’ll

know

the

answers

in

5

to

10

years’time,”

says

Debra

Lee

Magadini

from

Columbia

University.But

by

then,another

25

million

tons

of

plastic

will

already

be

in

the

ocean.6.The

A

baby

seal

is

sleeping

on

a

beach

in

Seattle.Its

mom

is

out

fishing

for

food

in

the

water.①对于这个海豹家庭来说，这是平静的一天。Suddenly,

people

on

the

beach

rush

over

to

the

baby

seal.

They

want

to

get

a

closer

look

at

it.

Some

try

to

feed

it.

Noemi,

a

student

volunteer

from

a

group

called

Seal

Sitters,

and

other

volunteers

find

the

seal

baby.

The

baby

is

now

scared.

And

the

mom,

looking

on

from

the

waves,

is

just

as

frightened.

They

close

off

the

areas

around

the

baby

with

yellow

tape.

Then

they

stand

guard

from

about

100

yards

away

to

watchover

the

baby

with

binoculars（双筒望远镜）

.

If

people

try

to

get

near

the

baby,

they

will

stop

them,

“If

people

crowd

around

the

baby,

the

mother

might

be

so

afraid

that

it

won’t

come

back

for

the

baby.

”

Why

shouldn’t

the

seals

be

disturbed?

One

big

reason

is

that

seal

babies

really

need

their

moms.

Like

most

baby

mammals

（哺乳动物）

，seal

babies

feed

on

their

mothers’milk.

If

the

babies

are

kept

apart

from

their

moms,

they

are

likely

to

die.

Second,

seals

are

also

hurt

by

pollution.

People

sometimes

leave

garbage,

such

as

plastic

bags,

on

the

beach.

Noemi

and

the

group

try

to

keep

the

beach

clean.

②

They

don’t

want

the

animals

to

eatthings

that

could

make

them

sick.

“I

love

seals,

”

says

Noemi,

“and

I

want

to

protect

them.

”10.请在文中找出与“the

mother

might

be

too

afraid

to

come

back

for

her

baby”意思相同的句子。_____________________________________________________________the

Man

did

not

have

to

think

about

the

protection

of

his

environment

in

the

past.

There

were

not

many

people

on

the

earth,

and

natural

resources

seemed

to

be

unlimited.

Today,

things

are

different.

There

are

too

many

people

on

the

earth.

We

are

using

up

our

natural

resources

too

quickly,

and

at

the

same

time

we

are

polluting

our

environment

with

dangerous

chemicals.

If

we

continue

like

this,

human

life

on

the

earth

will

not

survive.

Everyone

realizes

today

that

if

too

many

fish

are

taken

from

the

sea,

there

will

soon

be

none

left.

Yet,with

modern

fishing

methods,

more

and

more

fish

are

caught.

We

know

that

if

people

cut

down

moretrees,

forests

will

disappear

and

nothing

will

grow

on

the

land.

We

realize

that

if

rivers

are

polluted

with

waste

products

from

factories,

we

will

die.

However,

in

most

countries,

waste

products

are

still

put

into

rivers

or

into

the

sea,

and

there

are

few

laws

to

stop

this.

We

know,

too,

that

if

the

population

of

the

world

continues

to

rise

at

the

present

rate,

in

a

few

years,

there

will

not

be

enough

food.

What

can

we

do

to

solve

these

problems?

If

we

eat

more

vegetables

and

less

meat,

we

will

easily

get

more

food.

Land

that

is

used

to

grow

crops

can

feed

five

times

more

people

than

land

where

animals

are

kept.

The

world

population

will

not

rise

so

quickly

if

people

use

modern

control.
