listeningmaterialThe

conversation

is

about

the

City

of

Science

and

Industry,

a

museum

in

Paris.

Would

you

like

to

go

to

this

museum?

Why

or

why

not?No.It

is

not

convenient

because

it

is

too

far

from

China

and

there

is

no

need

to

go

so

far

when

we

have

so

many

interesting

places

at

home.We

can’t

speak

French

and

will

have

trouble

in

understanding

what

to

do

there.Post-listening:talkaboutsomethingmoreonthescientificmuseumYes.I

would

like

to

go

to

this

museum

to

see

the

blue

screen.

I

am

curious

to

know

what

on

earth

is

going

on

there

and

why

I

can

see

my

blood

cells

moving

around

like

tiny

bright

lights.

I

am

sure

it

will

be

a

lot

of

fun.2.Ifyouwereaguideinthesciencemuseum,whatsciencephenomenonwillyouintroducetovisitors?Let'stalkaboutscientificphenomenaToday,Iwanttotalktoyouaboutaverystrangephenomenoncalledanon-Newtonianliquid.Youcanmakeiteasilyusingequalpartsofwaterandcornflour,likeIhavehere.Anon-Newtonianfluidisstrangebecauseyoucanpouritlikealiquid,butifyouputanypressureonit,itsuddenlybecomeshardasconcrete.Infact,itbecomeshardenoughtostandon.Then,assoonasyoutakethepressureoff,itbecomesaliquidagain.Thisshowthatitispossiblethatsomethingcanexistasaliquidandasolidatthesametime.topicexplanationsummaryPost-listening:SampleStudyTalkaboutthe“WaterFilmExperiment”intheTiangongspacestation.EXAMPLEToday,
