innovations

are

made

with

the

aim

of

makingmoney

for

a

few.

This

is

because

it

is

the rich

andpowerful

people

in

our

society

who

have

enoughmoney

to

impose

changes

(such

as

working

conditions)that

are

in

their

own

interests.In

many

countries,

the

birth

rate

is

decreasing

so

thatfamilies

are

smaller

with

fewer

children.

Thesechildren

are

often

spoilt,

not

in

terms

of

love

andattention

because

working

parents

do

not

have

the

timefor

this,

but

in

more

material

ways.Firstly,

a

person

needs

to

feel

that

they

are

doingvalued

and

valuable

work,

so

positive

feedback

fromsuperiors

is

very

important

in

this

respect.Their

adult

world

will

be

changing

constantly

in

termsof

technology

and

the

Internet

is

the

key

to

all

theknowledge

and

information

available

in

the

worldtoday.

Therefore

it

is

important

that

children

learn

at

anearly

age

to

use

the

equipment

enthusiastically

and

with

confidence.The

greater

flexibility

of

the

primary

timetable

allowsfor

more

frequent,

shorter

sessions

and

for

a

play-centred

approach,

thus

maintaining

learners’enthusiasm

and

progress.2.举例展开To

do

this,

we

need

to

improve

the

choice

of

public

transportservices

available

to

travellers.

For

example,

if

sufficient

skytrains

and

underground

train

systems

were

built

and

effectivelymaintained

in

our

major

cities,

then

traffic

on

the

roads

would

bedramatically

reduced.Physical

activity

could

be

encouraged

relatively

cheaply,

forexample

by

installing

exercise

equipment

in

parks.We

have

been

moving

on from

previous

ways

of

doing

things.Some

technologies,

such

as

weapons

of

mass

destruction,

are

ofnegative

impact.

Others,

such

as

medical

advances,

positivelyhelp

people

to

live

better

or

longer,

and

so

very

much

helptraditional

ways

of

life.Give

reasons

for

your

answer

and

includeany

relevant

examples

from

your

ownknowledge

or

experience.3.对比或类比展开The

majority

of

stars

do

not

hold

their

top

position

long.

Sportsstars

and

pop

stars,

for

example,

are

soon

replaced

by

the

nextyounger,

more

energetic

generation,

while

the

good

looks

ofmost

film

stars

quickly

fade.A

young

adult

who

passes

directly

from

school

to

university

israther

restricted

in

terms

of

general

knowledge

and

experience

ofthe

world.

By

contrast,

those

who

have

spent

some

time

earning

a

living

or

travelling

to

other

places

have

a

broader

view

of

lifeand

better

personal

resources

to

draw

on.Tips：while和whereas都是用来在一个复杂句里引导从句与主句形成对比，而bycontrast，则是引导一个完整句子去与它前面的一个完整句子之间形成对比，而while和whereas的后面不能跟逗号。The

greatest

benefit,

though,

is

that

maturity

gives

usgreater

confidence

in

our

own

judgement,

in

all

areas

oflife.

We

are

no

afraid

to

express

our

opinion

when

others

disagree

and,

unlike

a

teenager,

we

know

when

tolet

things

go.It

allows

more

equally

among

pupils

and

gives

moreopportunity

to

all

those

at

the

school

to

choose

subjectsmore

freely

without

gender

prejudice.

For

example,

amuch

higher

proportion

of

girls

study

science

to

a

highlevel

when

they

attend

girls’

schools

than

theircounterparts

in

mixed

schools

do.

Similarly,

boys

insingle-sex

schools

are

more

likely

to

take

cookeryclasses

and

to

study

languages,

which

are

often

thoughtof

as

traditional

subjects

for

girls.4.让步展开In

my

country,

many

advertising

companies

produce

advertisementswith

famous

and

popular

actors

or

singers.

People,

especiallyyoungsters,

buy

goods

that

their

favourite

singer

advertise,

althoughthey

do

not

really

need

the

products.Those

who

believe

teenagers

are

the

happiest

people

cite

their

lackof

responsibilities

as

a

significant

factor.

They

are

supportedfinancially

and

emotionally

by

their

parents,

and

although

they

maybe

included

in

family

decisions,

they

are

not

ultimately

responsible.Reaching

the

conclusion

that

change

is

inevitable

is

not

the

same

asassuming

that

change

is

always

for

the

better.

Unfortunately,

it

is

notalways

the

case

that

new

things

are

promoted

because

they

havegood

impacts

for

the

majority

of

people.5.假设展开Today,

education

has

become

a

priority

for

many

parents

seeking

tosecure

a

good

future

to

their

children

in

this

rapidly

changing

world.They

believe

that

if

their

children

work

hard

at

school,

then

they

will

increase

their

opportunities

for

going

to

higher

education

andeventually

getting

a

good

job.In

better

economic

circumstances,

few

patents

would

choose

to

sendtheir

children

out

to

full-time

paid

work.

If

learning

responsibilitiesand

work

experience

are

considered

to

be

important,

then

childrencan

acquire

these

by

having

light,

part-time

job.Primary

school

teachers

are

generalists,

and

may

not

have

thenecessary

language

skills

themselves.

If

specialists

have

to

bebrought

in

to

deliver

these

sessions,

the

flexibility

referred

to

aboveis

diminished.Tips：除了直接使用if...,...或者if..,then...来搭建起假设逻辑关系外，还经常使用be

likely

to...,

be

less

likely

to...,

beunlikely

to...,

may和虚拟语气等手段来展开支持关系。To

do

this,

we

need

to

improve

the

choice

of

publictransport

services

available

to

travelers.

For

example,

ifsufficient

sky

trains

and

underground

train

systems

werebuilt

and

effectively

maintained

in

major

thentraffic

on

the

roads

would

be

dramatically

reduced.Advocates

of

this

believe

that

today’s

sedentarylifestyle

and

stressful

working

conditions

meanthat

physical

activity

is

no

longer

part

ofeitherour

work

or

our

leisure

time.

If

are

allowed

to

have

whatever

they

want,

regardless

ofprice,

and

to

behave

as

they

please.

This

means

that

the

childrengrow

up

without

consideration

for

others

and

without

anyunderstanding

of

where

their

standard

of

living

comes

from.Those

who

have

spent

some

time

earning

a

living

or

traveling

toother

places

have

a

broader

view

of

life

and

better

personalresources

to

draw

on.

They

tend

to

be

more

independent,

which

is

a

very

important

factor

in

academic

study

and

research,
