since的用法:译作“自从…以来”
1)接时间点:如
I
have
stayed
in
that
country
since
1995.
要求:谓v.用现在完成时,而且须是延续性动词。
2)接一段时间
+
ago:如
They
have
lived
in
that
house
since
two
years
ago.
要求:谓v.用现在完成时,而且须是延续性动词。
3)接时间状语从句:如
I
have
loved
her
since
I
met
her
last
time.
/
Lily
has
stayed
at
home
since
she
left
school.
要求:主句的谓v.用现在完成时,而且须是延续性动词;从句的谓v.用一般过去时,而且须是终止性动词。
4)用于句型“It’s
/
It
has
been
+
一段时间
+
since
+
时间状语从句”中,译作“自从…以来,
已经…(时间)了”。如
It’s
/
has
been
three
months
since
he
moved
to
this
city.
要求:主句的谓v.用一般现在时或现在完成时;从句的谓v.用一般过去时,而且须是终止性动词。
5)用于句型“一段时间
+
has
passed
since
+
时间状语从句”中,译作“自从…以来,
…
(时间)已经过去了”。如上个例句还可写成:Three
months
has
passed
since
he
moved
to
this
city.
要求:主句的谓v.用现在完成时,而且动词必须是has
passed;从句的谓v.用一般过去时,而且须是终止性动词。
6)注:当since用于否定句时,主句的谓v.可以是终止性动词。如
He
hasn’t
seen
the
film
since
last
month.
7)相关词组:“从那时起”:ever
since、since
then、from
then
on.注:ever
since作为一个词组,放句尾可单独使用。如I
have
given
up
smoking
ever
since.
另外,还可在since后接句子。since前加ever,只是加重语气而已。如
I
have
given
up
smoking
ever
since
I
caught
a
bad
cough.
8)
since还可引导原因状语从句,译作“由于;因为”,相当于because。如
Since
he
was
lazy,
he
didn’t
finish
his
homework.

咋说呢
since作为原因状语从句,
相当于now
that,意思是“因为……,既然……,
鉴于……”。
since表示原因时,
语气比because弱,
表示的原因是对方已知的,或是句中不很重要的部分,
是附带的原因,
因此引导的从句不是信息的焦点,
不能回答why的提问,
也不能用在强调句型中作为被强调的内容。since引导的从句往往放在主句之前。
希望对你有帮助

since可引导原因状语从句,译作“由于;因为”,相当于because。如
He
didn’t
finish
his
homework
since
he
was
lazy.即:现象(一句话)+since+从句(遵照所有从句语序)
