Grammar
(1)其中the

in
the
minute
/the
moment/instantly
he

Grammar
(2)另外还要注意hardly…when…,scarcely…when…,
no
sooner…than…的意义和用法。意思是“一…就…”,通常都是hardly,
scarcely,
no
sooner
位于句首,他们后面的主句用had
done,且倒装。而when,
than后面的从句用一般过去时。
例句:

had
I
got

I
see
her,she
always
wears
a
smile.

4.till和until
(till不可以位于句首)
在肯定句中,主句的谓语动词是延续性动词,而在否定句中,主句的谓语动词是瞬间性动词。
例句:
He

bed
until/till

lived
here
since

came
here.
自从我来到这儿,我一直生活在这儿。
It
is/has
been
five
years
since
I
last
met
him.
我已经五年没见他了。
【提示】
时间状语从句中常用一般现在时表示将来;当从句的动作先于主句的动作发生时,则用现在完成时表示将来。
例句:
When
I
come
back,I'll
go
to
see
my
parents.
我回来时要去看望父母。
You
can't
go
out
to

until
you
have
finished
your

Grammar
when/while/as引导时间状语从句时的区别:
1.作为“当…时”讲,when可以和延续性动词连用,也可以和短暂性动词连用,而while和as只能和延续性动词连用。
Grammar
eg:
Why
do
you
want
a
new
job
when
you’ve
got
such
a
good
one?
Sorry,
I
was
out
when
you
called
me.
Strike
while

hot.
The
students
took
notes
as

listened.
get
为短暂性动词
call为短暂性动词
is为延续性动词
listen
为延续性动词
2.when从句的谓语动词可以在主句动词之前或之后发生或同时发生。while引导的从句强调主句和从句的动作同时发生(或者相对应)。
例如:
When
he
had
finished
his
homework,
he
took
a
rest.
When
I
got
to
the
airport,
the
guests
had
left.
也就是说当主从句动作同时发生,且从句动作为延续性动词时,
三者可互换。
例句:
When/While/As
she
was
making
a
phone
call,
I
was
writing
a
letter.
Grammar
had
finished
先发生
got
to
后发生
Grammar
while有时还做并列连词“然而”表对比和从属连词
“尽管”的意思,
相当与though/although。
While
my
wife
was
reading
the
newspaper,I
was
watching
TV.
(read
是延续性的动词,was
reading和was
watching同时发生)当我妻子看报纸的时候,我正在看电视。
I
like
playing
football
while
you
like
playing
basketball.
我喜欢踢足球,而你喜欢打篮球。
Grammar
when有时表示“就在那时”通常用在以下句型中
be
about
to
do…when…
had
done…when…
be
doing…when…
be
on
the
point
of
doing…when…
例如:
When
she
came
in,I
stopped
eating.
她进来时,我才刚吃完饭。
我正打算出去这时电话响
我正在读书这时有人敲门。
I
was
about
to
go
out
when
the
phone
rang.
I
was
on
the
point
of
reading
books
when
someone
knocked
at
the
door.
3.as表示“在……的同时,一边……一边”,as引导的动作是延续性的,一般用于主句和从句动作同时发生时;as也可以强调一先一后;as还可译为“随着”。
例如:
We
always
sing
as
we
walk.
我们总是边走边唱。
As
we
were
going
out,it
began
to
rain.
当我们出门时,天开始下雨了。(as强调句中两个动作紧接着先后发生,而不强调开始下雨的特定时间。)
As
time
went
on,he
grew
weaker
and
weaker.
随着时间的流逝,他身体越来越弱了。
Grammar
4.
在将来时的从句中常用when,
且从句必须用一般现在时
You
shall
borrow
the
book
when
I
have
finished
reading
it.
5.
when还用在表示“一…就…”的句型中。
Hardly/Scarcely

引导词可能是单个的单词,也可能是由多个单词组成的连词;原因状语从句大都放在句首,有时也放在句末。
引导词或词组
because,since,as,now
that等
Grammar
常见的用法主要有:
1.because“因为,由于”,在引导原因状语从句的连词中,because的语气是最强的,表示主句谓语动词的直接原因,常用来回答以why开头的疑问句。
例如:
1.
The
boy
was
absent
because
he
was
ill.
那个男孩因病缺席。
2.
—Why
can’t
you
go
there
now?
—你现在为什么不能去那里?
—Because
I’m
too
busy.
—因为我太忙了。
Grammar
2.as“因为,由于”,如果原因很明显或估计对方是知道的,从句用as引导时较多;有时有“既然”的意思。
例如:
As
I
have
not
read
the
book,I
cannot
tell
you
anything
about
it.
由于我没有读过这本书,所以无法告诉你有关它的事情。
She
stayed
at
home
as
she
had
no
car.
她因没有汽车而待在家里。
As
you
are
sorry,I’ll
forgive
you.
既然你已感到抱歉,那我就原谅你吧。
Grammar
3.since“因为,既然”,它引导的从句通常放在句首,常表示已为人们所知的原因或理由。
例如:
Since
it
is
late,I
shall
go
home
now.
由于时间晚了,我现在要回家了。
Since
you
are
so
sure
of
it,he’ll
believe
you.
既然你对此这么有把握,他会相信你的。

has
stopped,let’s
go
home
at
once.
既然雨已停了,让我们立刻回家吧。
Now
that
they
are
all
gone,you
can
tell
me
the
secret.
既然他们都走了,你可以告诉我这个秘密了。
而下面这句话就只能用
since,不能用
now
that:

one

can’t
discuss
it.
既然没人读过这本书,我们就不能对它进行讨论。

6.原因状语从句中应注意的问题
as,
because,
for,
since
的区别
1>
as作为从属连词引导原因状语从句时,语气不如because
强烈。它引导的从句常放在句首,
说明原因,后面的主句
则说明结果。
2>
because
引导从句时,
语气最强,
直接回答why的问句,
引导的句子是语意中心所在,
一般在句后。
3>
for作为并列连词,多用于书面语中,表示原因,
语气最弱,
往往含对所作论述提供情况或补充说明之意。它引导
的句子一般在主句之后。
4>
它表示的原因是双方已知道的。
now
that(=since)是一个连词词组,作“既然”讲,引导原因状语从句。语气较弱,强调人们已知的事实。在口语中that常可省略,而只有now连接从句。because比now
that与since表示的原因更直接
用法
语气
意义
now
that

for
连接并列句
较弱
表示对主句进一步解释说明,附加或推断的理由。
