用某人/某物替换某人/某物（3）replacesth.+prep./adv. 把某物放回到……replace是动词place(放置)加前缀re构成的动词,所以它有“放回”之意。常见的加前缀re的动词还有:remarry,replay,rebuild,rewrite,reappear等。【即讲即练】(1)Itwouldbedifficulttofindamantotaketheplace______thepresentmanager.(2)Thelibrarianaskedme_______(replace)thebookontheshelfafterreading.(3)(2014·山东高考)It’llbepossibletoreplacethebrushonthehandle_______abrushingunitthatalsohasacamera.2.thanksto“幸亏,多亏”,多用于表达正面意思,相当于感谢,在句中作状语和表语。【教材原句】Inaddition,importantadvanceshavebeenmadeinmedicineandenvironmentalsciencethankstoincreasingputerpower.【归纳拓展】其他类似用法总结(1)owingto由于(2)dueto由于(3)becauseof因为(4)asaresultof由于【即讲即练】(1)Thanks____youradvice,thetroublewasavoided.(2)________(owe)toalackoffunds,theprojectwillnotcontinuenextyear.(3)Theydidn'tclimbthemountainbecause_______therain(4)（改错）Hedidn’tpassthecollegeentranceexaminationasaresulthislaziness.3.强调句型【教材原句】Sowhatisitthatinspiresustoinventthings?【句型精讲】(1)Itis/was...that/who可以对除谓语以外的成分进行强调。当强调部分为“人”时,可用that或who,其他情况下用that。*Itwashimthatwemetattheschoolgate.(2)在强调句中,当强调主语时,其后的谓语动词应和主语在人称和数上保持一致。*ItisWhiteandBettywhooftendogooddeedsfortheoldlady.(3)如果原句的谓语动词是现在时或将来时,强调句结构须用:Itis...that/who...;如原句的谓语动词是过去时态,则强调句结构须用Itwas...that/who...。(4)“not...until...”句型的强调结构为“Itis/wasnotuntil...that...”。*Itwasnotuntil11o’clocklastnightthathewenttobed.(5)强调句型的一般疑问句形式:Is/Wasit+被强调部分+that/who+其他成分。*Wasitin1939thattheSecondWorldWarbrokeout?(6)强调句的特殊疑问句句型为:疑问词+is/was+it+that/who...?*WherewasitthatyoumetJackyesterday?【即讲即练】(1)(2014·福建高考)Itwastheculture,ratherthanthelanguage,________madeithardforhimtoadapttothenewenvironmentabroad.(2)(2014·湖南高考)It’snotdoingthethingswelike,butlikingthethingswehavetodo___________________(使生活愉快).(3)(2013·重庆高考)________________________________(正是在当地导游的帮助下)thatthemountainclimberwasrescued.(4)Itwasnotuntilneartheendoftheletter____________________________(她才提到自己的计划).答案:1.(1)of(2)toreplace(3)with2.(1)to(2)Owing(3)of(4)asaresult后加of3.(1)that(2)thatmakeslifehappy(3)Itwaswiththehelpofthelocalguide(4)thatshementionedherownplanⅨ阅读理解

What

are

your

retirement

plans?

Keep

working?

Get

more

exercise?

Or

learn

something

new?

You

may

put

them

on

hold.

There's

a

chance

that,

sooner

or

later,

you

might

have

to

move

further

than

you

were

thinking.

As

far

as

Mars(火星).

On

Thursday,

National

Geographic

will

show

the

first

ever

Mars

showhome,

giving

earthlings

an

idea

of

what

their

life

could

look

like

on

the

Red

Planet.

Set

in

the

notsodistant

year

of

2037,

the

iglooshaped

structure

could

be

the

home

of

your

future.

It

shows

a

house

built

using

recycled

spacecraft

parts

and

Martian

soil,

called

regolith,

which

has

been

microwaved

into

bricks.

Some

parts

of

the

home

are

recognisable

—

kitchen,

bedroom

—

but

there

are

fundamental

differences

that

are

vital

for

human

survival.

As

the

Martian

atmosphere

is

around

one

hundredth

as

thick

as

the

Earth's,

people

will

need

permanent

shelter

from

the

sun

and

society

will

move

largely

indoors.

Most

buildings

will

be

connected

by

underground

passages

and

the

houses

won't

have

windows.

The

homes

will

have

simulated

solar

lighting,

or

natural

light

that

has

been

bent

several

times.

Walls

will

need

to

be

10

to

12

feet

thick,

to

protect

people

from

dangerous

rays

that

can

pass

through

six

feet

of

steel,

and

a

double

airlocked

entrance

to

keep

home

under

proper

pressure.

"We

don't

think

of

our

houses

as

things

that

keep

us

alive,

but

on

Mars

your

house

will

be

survival

centre,"

says

Stephen

Petranek,

author

of

How

We'll

Live

on

Mars.

This

is

not

just

the

stuff

of

scifi.

"Ten

to

twenty

years

from

now

there

will

certainly

the

people

on

Mars,"

Petranek

says.

"We've

had

the

technology

for

30

years

to

land

people

on

Mars,

but

we

haven't

had

the

will,"

Petranek

says.

But

two

main

factors

have

"pletely

swung

public

attitudes".

The

private

panies'

participation

has

forced

government

agencies

to

up

their

game,

and

influential

films

such

as

Gravity

and

The

Martian

have

caught

society's

eye.1.Whatcanweknowabouttheshowhomefromthetext?A:Ithasnowindowsordoorsduetosecurityconcern.B:Itsdesignpresentstheideaofenvironmentalprotection.C:Ithasthickwallskeepingthehomeunderproperpressure.D:Itsundergroundpassagesconnectallthebuildingstogether.2.Whatdoestheunderlinedwords"putthemonhold"inParagraph1probablymean?A:Putthemoff.B:Givethemaway.C:Carrythemthrough.D:Takethemseriously.3.AccordingtoPetranek,whathasspeduptheprocessofsendingpeopletoMars?A:ThegreatinfluenceofMarsshowhome.B:Thedevelopmentofrelatedtechnology.C:Thepetitionfromprivatepanies.D:ThepopularityofinfluentialbooksonMars.4.Whatisthebesttitlef
