He,

the

Columbus

of

the

East,

was

an

amazing

man.

He

was

born

in

1371

and

11

years

later,

was

caught

by

the

army

of

a

rich

young

man

called

Zhu

Di

and

made

to

work

for

him.

Over

time

the

rich

man

saw

tha

Zheng

HE

was

very

clever

and

strong

and

they

became

close

friends.

In

1403

Zhu

Di

was

made

the

King

of

China

and

he

asked

Zheng

He

to

join

his

new

government.

The

king

wanted

to

learn

more

about

the

world

and

show

other

countries

his

power.

He

led

many

new

ships

to

be

built

and

made

Zheng

He

their

leader.

Between

1405

and

1433,

Zheng

He

led

seven

sea

trips

to

different

parts

of

the

world.

He

certainly

travelled

to

India,

Africa

and

the

Middle

East.

A

few

people

think

his

ships

may

have

even

reached

south

America

and

Australia.

Each

trip

lasted

between

two

and

four

years

and

it

is

believed

he

sailed

more

than

50,000

kilometrs

during

the

years

of

his

travels.

With

28,000

men

and

over

300

ships,

such

as

boats

for

food,

water

and

even

soldiers’

horses,

Zheng

He

led

a

fleer（舰队）whose

size

would

not

be

equaled

by

Europeans’

for

over

500

years

later.

On

these

trips

he

brought

with

him

many

Chinese

goods

like

silk

and

medicine

to

give

to

foreign

kings

or

to

sell

for

local

goods.

He

returned

from

each

trip

with

boats

filled

with

expensive

things

such

as

gold

and

jewellery,

foreign

guests

and

strange

animals

like

a

giraffe.

It

is

a

pity

that

we

may

never

learn

everything

about

Zheng

He’s

travels.

After

he

died

in

1433,

the

new

king,

who

believed

these

trips

were

unlucky

and

too

expensive,

had

them

stop

and

he

burned

almost

all

the

books

about

Zheng

He’s

travels.

It

is

only

in

the

last

50years

that

historians

have

begun

to

carefully

study

the

adventures

of

the

great

Zheng

when,

while

和

as

引导时间状语从句的用法

（一）、when

的用法

如果只从现象来看，when

从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。

1.

When

she

came

into

my

room,

I

was

just

reading

a

book.

她走进我房间时，我正在看书。

2.

He

was

on

the

point

of

leaving

when

someone

knocked

at

the

door.

他正要走，这时有人敲门。

根据以上的例句，我们可以总结出一点：when

从句的A事件，相当于另一个事件B发生的时间点。也就是说，when

从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when

多数情况下用的是一般过去时，则不用正在进行时。因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。根据这一点，有的文章补充说：when

从句的动词大多是瞬时动词。这种说法也可以参照。

实际上，when

从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。例如：

When

I

got

to

the

airport,

the

guests

had

left.

当我赶到飞机场时，客人们已经离开了。

2.

When

he

had

finished

his

homework,

he

took

a

short

rest.

当他完成作业后,他休息了一会儿。

(二)、while

的用法

相比于when

来说，while

从句的侧重点就不一样了。while

从句的侧重点在于描述动作正在发生的状态，它的意思是：当while

事件正在发生的时候，另一件事如何如何。所以，while

从句一般用的是正在进行时。而另一件事的状态没有硬性的要求，根据具体情况而定。例如：

1.

While

my

wife

was

reading

the

newspaper,

I

was

watching

TV.

当妻子正在看报纸的时候，我正在看电视。

2.

While

they

were

talking,

the

bell

rang.

正在他们谈话的时候，上课铃响了。从时间的角度来看，while表示的是一段时间，是一个过程。这是while的侧重点。因此，如果含有“一段时间”的含义的时候，就可以用while。3.Strikewhiletheironishot.趁热打铁。这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。（三）、as

的用法

as

从句表示的也是一件事情正在发生，另一件事也正在进行当中。但与

while

从句不同的是，as

从句用的一般不用正在进行时，而只是一般过去时。as

从句一般可以翻译成“边……边……”。例如：

1.

As

my

mother

sang

those

old

songs,

tears

ran

down

her

cheeks.

当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。

2.

The

students

took

notes

as

they

listened.

学生们边听课边做笔记。

as

表达的事件，往往只是主句动作发生的背景或条件时，as

只是一个次要的时间说明，不像while

从句有强调

while

动作本身的意思。因此，as

常常翻译成“随着……”之意。例如：

As

the

time

went

on，the

weather

got

worse.

随着时间的推移，气候更加糟糕。

2.

The

atmosphere

gets

thinner

and

thinner

as

the

height

increases.

随着高度的增加，大气越来越稀薄。少数情况下，如果强调动作正在发生，as

从句也可以用正在进行时。这只能算是特例了。

The

sad

mother

sat

on

the

roadside,

shouting

as

she

was

crying.

伤心的妈妈坐在路边，边哭边叫喊。

2.

As

we

were

going

out,

it

began

to

snow.

正当我们出门时，雪开始下起来。（四）、when,

while,

as

的互换

如果从句动作和主句动作同时发生，并且从句动作为延续性动词时，when，while，as

可以互换使用。

1.

When

/While

/As

we

were

dancing,

a

stranger

came

in.

当我们跳舞时，一位陌生人走了进来。

[dance

为延续性动词]

2.

When

/While

/As

she

was

making

a

phone

call,

I

was

writing

a

letter.

比较while,when,asas,when引导短暂性动作的动词。例如：Justas/Justwhen/WhenIstoppedmycar,amancameuptome.我刹车后，有一个人向我走来。当从句的动作发生于主句动作之前，只能用when引导这个从句，不可用as或while。例如：Whenyouhavefinishedyourwork,youmayhavearest.干完活后，你可以休息一下。从句表示“随时间推移”连词能用as，不用when或while。例如：Asthedaywenton,theweathergotworse.日子一天天过去，天气越变越坏。扩充知识点：

It

is

since从以来多长时间了(因为since

+从句或名词，表示一段时间)

It

is

five

years

since

we

met

last

time.从我们上次见面已经五年了。

It

is

+before，(才)

It

was

a

long

time

before

I

went

to

sleep

again.

过了很长时间我才睡着。

It

was

an

hour

before(＝until)

the

police

arrived.

过了一个小时，警察才来。

2.由as

soon

as,

immediately,

directly,

instantly,

the

moment,

the

instant,

the

minute,

等引导的时间状语从句。

这些连词都表示“一就”。例如：

I

will

go

there

directly

I

have

finished

my

breakfast.

吃完早饭，我立即到那里去。

The

moment

I

heard

the

news,

I

hastened

to

the

spot.我一听到消息，马上赶到了出事地点。

3.由by

the

time引导的时间状语从句。

注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时；如果主句的谓语动词用一般现在时，主句的谓语动词用将来完成时。例如：

By

the

time

you

came

back,

I

had

finished

this

book.到你回来时，我已经写完这本书了。

By

the

time

you

come

here

tomorrow,

I

will

have

finished

this

work.

你明天来这儿的时候，我将已经完成此工作了。

注意：when

while

as

after

before

as

soon

as

since

till

/until

by

the

time

在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。
