英语里除了现在进行时,为什么有的词还是ing形式?
英语里除了现在进行时,为什么有的词还是ing形式?
英语里除了现在进行时,为什么有的词还是ing形式?
2.一些特殊表达..如:be good at doing sth
enjoy doing sth.
be busy doing
feel like doing
thank you for doing
do some cooking/cleaning/reading/shopping/washing
go swimming/fishing/shopping/skating/boating
二.动词现在分词由动词原形在词尾加ing构成,其规则如下:
1)一般情况下直接加ing think---thinking sleep---sleeping
study---studying speak---speaking
carry---carrying say---saying
2)以不发音的字母e结尾的单词,去掉字母e,再加ing
wake---waking make---making come---coming
take---taking leave---leaving have---having
3)以重读闭音节结尾,呈现“辅,元,辅”结构的动词,先双写末尾的辅音字母,再加ing .初中学过的这类词有:begin,cut,get,hit,run,set,sit,spit,stop,swim,beg,drop,fit,nod,dig,forget,regret,rid,等.(visit 不是以重读闭音节结尾,不用双写)
travel虽然重读第一音节,词尾音节不重读,但是现在分词仍要双写末尾辅音字母,然后再加ing ,如:travel---travelling.初中阶段此类词只有这一个.
4)以 y 结尾的动词 直接加 ing
carry—— carrying enjoy—— enjoying
5)以ie结尾的动词,把ie改为y ,再加ing
die---dying lie---lying
要特别注意有些动词没有进行时态.
1、表示状态、思想、感情和感觉的动词,如:see,hear,love,know,want,hope,think等,没有进行时态.
2、当have/has作为“拥有”时,没有进行时态,但表示“开会,吃饭,玩得高兴”等意思时,可以用进行时表达.I am having many books.(这是错误的句子)
I am having a good time.(这才是正确的句子)
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
某些动词后出现非限定性动词时只能用动名词作宾语,不能用不定式.常见的此类动词有:advise,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:
They went on walking and never stopped talking.他们继续走,说个不停.
I found it pleasant walking along the seashore.在海滩上走真是乐事.
(2)作介词的宾语
We are thinking of making a new plan for the next term.我们正考虑为下学期制定新的计划.
Shall we have a rest or get down to doing our work?我们休息呢还是开始干活?
(3)作形容词的宾语
The music is well worth listening to more than once.这种曲子很值得多听几遍.
We are busy preparing for the coming sports meet.我们正为马上到来的运动会忙着做准备.
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:
a walking stick =a stick for walking=a stick which is used for walking
a washing machine=a machine for washing=a machine which is used for washing
a reading room=a room for reading=a room which is used for reading
a measuring tape=a tape for measuring=a tape which is used for measuring
sleeping pills=pills for sleeping=pills which is used for sleeping
