【知识点1】现在进行时的陈述句
一、现在进行时的定义
现在进行时表示正在进行的动作或正在发生的事情,也可以表示当前一段时间内的活动或者现阶段正在进行的动作。标志性的词有look, listen, now等以及表示某一时间的短语,如at nine o’clock等。
二、现在进行时的陈述句结构
- 肯定句结构为:“主语 + be动词(am/is/are)+动词-ing +其他.”。 be动词必须与主语的人称和单复数形式保持一致。如:
I am doing my homework.
My grandfather is drawing.
- 否定句结构为:“主语 + be动词(am/is/are)+ not +动词-ing +其他.”。如:
My father is not sleeping.
They aren’t planting trees.
三、动词现在分词的构成
- 大部分动词直接在词尾加-ing。如:
play-playing | clean-cleaning | eat-eating | do-doing | go-going |
push-pushing | help-helping | visit-visiting | watch-watching | sleep-sleeping |
- 以不发音的e结尾的动词,先去e,再加-ing。如:
make-making | ride-riding | take-taking | write-writing | skate-skating |
have-having | dance-dancing | live-living | use-using | close-closing |
- 以重读闭音节结尾的动词,如果末尾只有一个辅音字母,则应先双写末尾字母,再加-ing。如:
run-running | swim-swimming | sit-sitting | put-putting | chat-chatting |
stop-stopping | dance-dancing |
|
|
|
部分以ie结尾的动词,先把ie改为y,再加-ing。如:lie-lying, die-dying, tie-tying

【知识点2】现在进行时的特殊疑问句
- 现在进行时的特殊疑问句结构
现在进行时的特殊疑问句结构为“特殊疑问词 +be动词 +主语 +动词-ing +其他?”,回答要根据实际情况。当疑问词在句中作主语时,现在进行时的特殊疑问句采用陈述句语序,即“疑问词 +be动词 +动词-ing +其他?”。当不确定主语是单数还是复数时,一般将作为主语的疑问词视作第三人称单数,be动词用is。如:
--What is he looking for? --He’s looking for juice.
--Where are you having lunch? --At school.
- 对现在进行时的陈述句划线部分提问
首先,确定疑问词,然后将疑问词代入特殊疑问句结构,即“特殊疑问词 +be动词 +主语 +动词-ing +其他?”。如果对主语进行提问,画线部分用who或what代替,其余不变;如果提问的部分是动名词或者动名词短语,则要改为doing;如果对地点进行提问,句首用where。
注意:画线部分不可以出现在提问的句子中。如:
She is brushing her teeth.(对画线部分提问)
→ What is she doing?
It is running in the street.(对画线部分提问)
→ Where is it running?
His friend is running.(对画线部分提问)
→ Who is running?
I am teaching your sister English.(对画线部分提问)
→ Who are you teaching English?
