原因目的和結(jié)果狀語從句初中精華

會計學(xué)1原因目的和結(jié)果狀語從句初中精華

(1)原因狀語從句：從句表示的是主句行為的原因。通常由because,

since,

as,

for引導(dǎo)。

(2)because表示直接原因（聽話人所不知的），語氣最強?；卮鹩蓋hy提出的問題，只能用because。此外，because和so不能同用在一個句子里。

例如：--Why

aren’t

going

there?--Because

I

don’t

want

to.

since相當(dāng)于now

that，“因為…，既然…，

鑒于…”表示顯然的或已為人知的理由，語氣較because弱

例如：Since

the

rain

has

stopped，let’s

go

for

a

walk.

既然雨停了，我們出去散散步吧。第1頁/共14頁as和since語氣較弱，一般用來表示明顯的原因。由as和since引導(dǎo)的原因狀語從句多放在句首。

例如

：As

he

has

no

car,

he

can’t

get

there

easily.

Since

we

have

no

money,

we

can’t

buy

it.

(4)for表示所說的理由是一種補充說明,for引導(dǎo)的從句一般不放在句子的開頭。如:

I

decided

to

stop

and

have

lunch,

for

I

was

feeling

quite

hungry.

Eg:1.

I

was

late

for

class

yesterday

_______

2.He

question,

通常由

so

that,

in

order

that（為了，以便）引導(dǎo)。

例:We

started

early

so

that

we

could

catch

the

first

train.

We

used

the

computer

in

order

that

we

might

save

time.

(2)so

that可引導(dǎo)目的狀語從句，此時可用to或in

order

to替換,將其改為簡單句。

例如：He

got

up

early

so

that

he

could

get

to

school

on

time.

=He

got

up

early（in

order）

to

get

to

school

on

time.第4頁/共14頁二、結(jié)果狀語從句

(1)結(jié)果狀語從句由so…that,

such…that,

so

that引導(dǎo)。

(2)so…that語such...that可以互換。在由so...that引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是:

“...so

+

形容詞（副詞）+

that

+

從句”。

例如：

He

was

so

glad

that

he

couldn’t

say

a

word.

Mother

lives

so

far

away

that

we

hardly

ever（幾乎不，從來不）

see

her.

二、結(jié)果狀語從句

(1)結(jié)果狀語從句由so…that,

such…that,

so

that引導(dǎo)。

(2)so…that語such...that可以互換。在由so...that引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是:

“...so

+

形容詞（副詞）+

that

+

從句”。

例如：

He

was

so

glad

that

he

couldn’t

say

a

word.

Mother

lives

so

far

away

that

we

hardly

ever（幾乎不，從來不）

see

her.

（3）so

that既可引導(dǎo)目的狀語從句，又可引導(dǎo)結(jié)果狀語從句。區(qū)別這兩種從句的辦法有兩個：A)目的狀語從句里往往帶有情態(tài)動詞can,

could,

may,

might等。B)從意思上看，目的狀語從句往往表示的目的很明確，不放在句首。

例如：

Speak

clearly

so

that

they

may

understand

you.

(目的狀語句)

Jack

is

badly

ill

so

that

he

has

to

rest.

that引導(dǎo)。

(2)so…that與such...that可以互換。在由so...that引導(dǎo)的結(jié)果狀語從句中，so是副詞，與形容詞連用。其結(jié)構(gòu)是:

“...so

第9頁/共14頁（2）在由such…that引導(dǎo)的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復(fù)數(shù)可數(shù)名詞，也可以是不可數(shù)名詞；其結(jié)構(gòu)是:

“...such

+a

/

an

形容詞+名詞+

that

+

從句”。

例如：

1.It

anything.

2.He

such

long

arms

that

有時上述兩種結(jié)構(gòu)是可以互換的。

例如：

It

was

such

a

wonderful

film

that

all

of

us

wanted

to

see

it

again.

=The

film

was

so

wonderful

that

all

of

us

wanted

to

see

it

again.

第10頁/共14頁(3)如果名詞前由many,

much,

little,

few等詞修飾時，只能用so,

例如：A.Soon

there

were

so

many

deer

that

they

ate

up

all

the

wild

roses.

B.He

has

so

little

time

that

he

can’t

(4)如果主從句的主語相同，并且從句是否定的形式，可以用too...to...句型轉(zhuǎn)化。

例如：He

so

excited

that

he

couldn't

go

to

sleep

that

night.

=

He

was

too

excited

to

go

to

sleep第11頁/共14頁5)如果主從句的主語相同，但從句是肯定的形式，可以用adj.+

enough替換。
