现在进行时的肯定句基本结构为be(am,is,are)+动词ing. 2.动词加ing的变化规则1)一般情况下,直接加ing,如:look - looking, climb - climbing, jump - jumping, play - playing, go - going , draw - drawing2)以不发音的e结尾,去e加ing.(see的e是发音的,所以不能去掉,要直接加ing。
see - seeing ) 如:make - making, have - having, ride - riding,write - writing, drive - driving3)如果末尾是一个元音字母和一个辅音字母,双写末尾的辅音字母,再加ing.(但是open却不属于这规则,而是直接加ing,open-opening)如:run - running, swim - swimming, sit - sitting,cut-cutting, hop - hopping, get - getting.3.现在进行时的肯定句基本结构为be(am,is,are)+动词ing. be会随着与不同的人称搭配而产生不同的变化。
如:I am playing football. You are watching TV. We are having a class. He is climbing trees.She is playing with her cat. It is running in the park. They are going home.把它们的变化编成一首顺口溜就好记多了!Look!我用am,你用are,Is 用在他,她,它,我们,你们,他们全用are。
现在进行时的基本机构:现在进行时由“am [is, are]+现在分词”构成。
be + doing这里一定要注意,基本形式一定要是be+doing形式,千万不能忘掉be动词;例如:i _________ (sing) a song now.he ________ (listen) to jackie at this time.look, she ________ (run) out of the classroom.当然,首先还是要会写doing形式。
