什么是ing形式?用在什么地方或情况?请不吝赐教。

现在进行时
二、 现在进行时
现在进行时用助动词be的人称形式加现在分词构成,它的肯定、否定、疑问形式如下:
i am working。
i am not working。
am i working?
现在进行时主要表示现在或现在这一阶段正在进行的动作。
where are they having the basket-ball match?
they are putting up the scaffolding。
he‘s showing a foreign guest round the city。
在不少情况下,表示正在进行的动作的汉语句子,并没有“正在”这样的字,在译为英语时却必须用进行时态:
how are you getting on with the work?
the work is going fairly smoothly。
you are making rapid progress。
it is blowing hard。
who are you waiting for?
whenever i see her,she is working in the garden。我每次看到她时,她总是在花园里干活。
在一般现在时所列的表示状态和感觉的动词,一般不能用于进行时态,因为他们不能表示正在进行的动作。但如果词义转变,能表示一个正在进行的动作,就能够用于进行时态,试比较下面的句子:
do you see anyone over there?你看到那里有什么人吗?
are you seeing someone off?你在给谁送行吗?

i hear someone singing。我听见有人唱歌。
they are hearing an english talk?他们在听一个英语报告。

what do you think of it?你觉得这怎么样?
what are you thinking about?你在想什么?
另外,表示无法持续动作的动词,一般不宜用于进行时态,但有些可以用于这个时态表示重复、即将等:
he is jumping up and down。她一上一下地跳着。
the train is arriving。火车就要进站了。
the old man is dying。老头病危了。
现在进行时有时可用来表示一个在最近按计划或安安排要进行的动作(这是多有一个表示未来时间的状语):
we are leaving on friday。
are you going anywhere tomorrow?
a foreign guest is giving a lecture in english this afternoon。
xiao hong!coming。
who is interpreting for you?
we are having a holiday next monday。
但这仅限于少量动词,如go,come,leave,start,arrive,lunch,return,dine,work,sleep,stay,play,do,have,wear等。
另外,“be going+不定式”这个结构经常用来表示即将发生的事或打算(准备)做的事:
i am afraid it is going to rain。
it is going to be rather cold tomorrow。
she is not going to speak at the meeting。
在这个结构中过去有许多人不赞成用go和come这两个动词,感到很别扭,主张不说are you going to go anywhere tomorrow?而说are you going anywhere tomorrow?不说is she going to come?而说is she coming?但现在在这种结构中用两个动词的人越来越多,这种用法基本上被大家接受了。
此外,在时间和条件状语从句中,间或也可用现在进行时表示将来的情况或一般情况:
do not mention this when you are talking with him。
remember that when you are taking a rest,some else is always working。
if she is still sleeping,do not wake her up。
现在进行时有时用来代替一般现在时,表示一个经常性动作或状态,这是或是为了表示一种感情(a)如赞叹、厌烦等,或是为了强调情况的暂时性(b)。
a. how are you feeling today?(比how do you feel today?更显亲切)
xiao hua is doing fine work at school。(比xiao hua does fine work at school。更富赞美)
he is always thinking of his work。表赞许
he is constantly leaving his thing about。她老是乱扔东西。(表不满)
he is always boasting。他老爱说大话。(表厌烦)
b.he is sleeping in the next room now。他现在现在是在隔壁房间睡了(不再原来房间睡了)。
the professor is typing his own letters while his secretary is ill。
where is he working?他现在在那里工作?(可能刚换工作)
for this week we are starting work at 7:30。
he is walking to work because his bicycle is being repaired。
be间或可用于进行时态,表示一时的表现:
you are not being modest。
he is being silly。
she is being friendly。
xiao hong is being a good girl today。
do not talk rot。i am being serious。
注: 在there和here引起的句子中,常可用一般现在时代替现在进行时:
here comes the bus。(=the bus is coming.)
there goes the bell. (=the bell is ringing.)
在某些情况下两种情况都可以用,没有多少差别:
i wonder (am wondering) how i should answer then.
does your leg hurt? (is your leg hurting?)
it itches (is itching) terribly.
my back aches (is aching).
i write (am writing ) to inform you.

前面有“be”动词:
如“am”、“is”、“are”.

帮你举例
1..句首的动词+ING
2..伴随状态动词+ING
