动词后什么时候加ing,什么时候不加,为什么

如题所述

1 一般情况下,直接在动词后加-ing
work ---- working
sleep ----- sleeping
study ----- studying
2 动词以不发音的-e结尾,要去-e加-ing
take ----- taking
make ----- making
dance ----- dancing
3 重读闭音节的动词,要双写词尾字母,再加-ing
cut ----- cutting
put ----- putting
begin ------ beginning
4 以-ie结尾的动词,把变成y再加-ing
lie ----- lying
tie ----- tying
die ----- dying
要加ING是因为你说的这件是正在发生
比如说:我在跑步。翻译为:I’m running.
我在唱歌。翻译为:I'msingsing.
要双写是因为你说的这个动词的结构的原因。
也就是说如果这个单词最后一个字母是辅音,而它前面有一个且只有一个双元音(a e i o u)时,这个动词变为V.ing(v.就是动词的意思)时,最后一个字母要双写.
比如说: forget- forgetting travel- travelling。
我们老师说就像汉堡包一样:辅音+双元音+辅音

正在做的动作就加ing,比如说她正在睡觉(she is sleeping )
加s的情况,如果是动词加s就是现在第三人称在做的事情(就是说她/他/它做什么),比如说她哭了(she crys)
如果是名词加s就是复数,就是这个东西有很多个。比如说三条狗(three dogs)

be动词(is.am.are).介词后面加ing形式。还有固定的词组搭配要记住

allow,
permit,
avoid,
consider,
enjoy,
finish,
give
up,
cannot
help,
imagine,
include,
keep,
keep
on,
mind,
miss,
put
off,
delay,
practise,
resist,
suggest,
depend
on,
think
about,
set
about,
succeed
in,
worry
about,
burst
out,
insist
on,
can’t
stand,
be
used
to,
get
used
to,
devote…to…,
look
forward
to,
pay
attention
to,
get
down
to等。如:

walking
and

stopped
talking.
他们继续走,说个不停。

along
the
seashore.

(2)作介词的宾语

of
making
a
new

next
term.

we
have
a
rest
or

down

our
work?

(3)作形容词的宾语

music
is
well
worth

to
more
than
once.

the
coming
sports
meet.

3、作表语
动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。表语动名词与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。
your
task
is
cleaning
the
windows.
你的任务就是擦窗户。(cleaning
the
windows
is
your
task.)
what
i
hate
most
is
being
laughed
at.
我最痛恨的就是被别人嘲笑。
(being
laughed
at
is
what
i
hate
most.)
4、作定语
动名词作定语往往表示被修饰词的某种用途。如:

walking
stick
=a
stick
for

which
is
used
for

a
washing
machine=a
