In

a

high

mountain

area

in

central

Utah

stands

the

world's

oldest,heaviest

and

largest

tree,Pando.

And

it's

dying!

Pando

means

“I

spread”

in

Latin

and

it's

a

name

that

makes

sense.

Pando

is

a

big

group

of

trees

that

all

grow

from

the

same

roots（根）.They

look

separate

but

are

all

connected

underground

by

their

roots.

With

all

these

roots

connected,the

whole

group

of

trees

can

share

water

and

food.#1.1

▲

In

summer,animals（mule

deer

and

cattle）

feed

on

the

new

leaves,making

it

difficult

for

the

trees

to

grow.

The

number

of

mule

deer

has

even

increased

because

their

natural

enemies（mountain

lions,bears）

have

disappeared.

The

second

problem

is

from

people.

Hikers

and

campers

like

this

area

because

of

the

colourful

leaves

in

autumn.

But

getting

too

close

and

stepping

on

the

new

growth

has

made

Pando

smaller

and

thinner

over

the

last

50

years.#1.2

Protecting

Pando

is

challenging.

Putting

fences（栅栏）

around

it

to

keep

animals

away

has

helped

new

growth.

But

deer

are

smart,and

they've

found

ways

to

get

through

the

fences.

Other

efforts

have

included

cutting

or

burning

part

of

Pando

to

encourage

new

growth.

Pando

grows

back

very

quickly

after

a

forest

fire,and

these

fires

do

not

reach

temperatures

that

would

kill

its

root

system.

Michael

Grant,one

of

the

scientists

who

helped

name

Pando,warns

if

the

trees

are

in

trouble,the

whole

ecosystem

will

be

in

danger

too.

We

need

to

make

people

understand

the

long-term

effects

of

our

actions.#1.41.［新考法·图片理解］Which

Scientists

wanted

to

learn

more

about

how

sea

lions

use

different

areas

of

the

seafloor

to

gather

food.

1.___Underwater

robots

are

expensive.

They

often

move

slowly,and

they

can't

go

everywhere.

So

scientists

came

up

with

a

good

idea—tying

cameras

to

sea

lions.

The

sea

lions

could

cover

large

areas

of

the

seafloor

quickly,and

go

deep

into

places

that

humans

can't

reach.#1.1.1B

The

scientists

chose

8

healthy

adult

females（雌性动物）

from

two

different

groups

of

sea

lions.

They

chose

females

because

they

would

soon

return

to

land

to

feed

their

young.2.___

3.___The

videos

recorded

the

seafloor

in

places

that

had

never

been

seen

before.

The

scientists

were

able

to

identify（识别出）

six

different

types

of

seafloor

environments.

Using

AI

and

the

information

from

the

videos,the

scientists

developed

a

special

tool.4.___

And

it's

correct

98%

of

the

time.

The

scientists

now

can

use

that

tool

to

make

good

predictions

about

what

the

seafloor

is

like,even

in

areas

that

haven't

been

studied.

Thanks

to

the

sea

lions,as

one

of

the

nine

researchers

said,“5.___”#1.1.5EDCFA.The

results

were

exciting.B.But

studying

the

seafloor

is

difficult.C.This

tool

can

“guess”

what

the

seafloor

is

like.D.The

animals

were

expected

to

collect

89

hours

of

videos.E.That

meant

the

scientists

could

easily

get

the

cameras

back.F.They

give

us

a

window

into

their

world

that

we

haven't

seen

before.课时达标3a—3cⅠ.根据句意及首字母或汉语提示写单词1.The

①The

fastest-growing

plant

in

the

world

is

bamboo.

Some

bamboo

grows

so

quickly

that

people

say

they

can

watch

it

grow.

The

speed

of

growth

depends

on（依赖）

the

type

of

bamboo,the

earth

and

the

season.

Normal

bamboo

grows

30100

cm

a

day.

It

usually

grows

in

tropical

areas.

It

can

also

be

found

in

other

parts

of

the

world.

Bamboo

plants

are

found

in

Asia,parts

of

Africa

and

South

America.

②Bamboo

is

a

wonderful

plant

for

many

people

around

the

world.

There

are

over

1,000

uses

for

it.

People

make

tables,clothes,and

people

can

also

eat

the

shoots

of

it.#2

③▲

People

used

it

because

it's

very

strong.

They

used

it

to

build

houses,boats

and

bridges.

The

Chinese

made

a

bamboo

bridge

over

the

Min

River

in

Sichuan,China

almost

1,000

years

ago.

Also,bamboo

is

still

used

to

build

houses

today,especially

in

China

and

the

Philippines.

④Bamboo

is

the

earliest

material（材料）used

to

make

the

light

bulb.

The

great

scientist

Thomas

Edison

did

not

invent

the

light

bulb,but

he

made

it

perfect.

He

wanted

the

material

inside

to

burn

for

a

long

period

of

time.

He

tried

over

1,000

different

types

of

materials.

None

worked

very

well.

One

day,he

tried

to

use

a

piece

of

bamboo

and

the

light

bulb

lit

up

for

over

a

thousand

hours.

This

invention

helped

other

scientists

to

make

the

modern

light

bulb

we

use

today.#41.What

can

from

the
