Have

you

seen

that

poster

with

the

clock?

It’s

so

good,

but

a

little

scary,

too.B:

I

know.

So

many

wild

animals

are

dying

out.

This

poster

says

that

between

150

and

200

species

die

out

every

day.A:

That’s

terrible.

We

really

need

to

do

something.

Why

are

so

many

species

dying?B:

Well,

some

animals

are

being

hunted

and

killed.

And

then

there’s

pollution

and

habitat

loss,

I

guess.

Animals

need

a

place

to

live

in,

just

like

us,

and

they

need

clean

air

and

water,

too.A:

It

seems

like

people

need

to

be

more

aware.B:

Absolutely

(绝对;当然).

More

people

need

to

know.A:

Yes,

they

should

make

more

of

these

posters—maybe

it

will

help

protect

the

wildlife.listeningandSpeakingListenagainandtakenotesofthemissingwords.Activity3：Listening为...说话，辩护我绝对相信...为...发声Activity3：ListeningListentothesecondpartandanswerthequestions.Circlethekeywordsbeforelistening.54Pronunciation---stressedsyllables音节是英语当中最小的单位。每个音节含有一个音节核，通常由元音音素构成，辅音是音节的分界线。所以，音节就分成单音节、双音节和多音节。1.两辅音之间不管有多少个元音，一般都是一个音节。如：bed，seat，beau'ty。2.两元音字母之间有一个辅音字母时，辅音字母归后一音节，如：stu'dent，la'bour。3.有两个辅音字母时，一个辅音字母归前一音节，一个归后一音节，如：let'ter，win'ter4.不能拆分的字母组合按字母组合划分音节。如：fa'ther，tea'cher。B.一般在第一个音节重读。如：sorry,movie,coverC.多音节词一般倒数第三个音节是重音。如：'difficult,oppor'tunity,'family,e'conomy,uni'versity
