often通常和一般現(xiàn)在時態(tài)連用,所以不會用-ing形式.置于用現(xiàn)單三形式還是原形,這取決用主語,如果主語是單數(shù)第三人稱,那就用現(xiàn)單三形式,其他情況下用原形。

often后什么時候加s和ing

I often play computer games.She often plays computer games.

當主語是第一人稱(I,We)、第二人稱(You,You)或者是第三人稱復數(shù)(They,students,teachers.)時,often后面的動詞不加-s

當主語是第三人稱單數(shù)(She,He,It,人名.)是often后面動詞加-s ing是不用加的，應該沒有這個說法。

often后面加動詞原形還是加s，這是分情況的。若主語為第三人稱單數(shù)（他，她，它），則動詞應變?yōu)榈谌朔Q單數(shù)形式。多數(shù)動詞后跟s，特殊的動詞會跟es,如：do-does,go-goes.若主語為除第三人稱單數(shù)外的人稱（你，我，你們，我們，他們，她們，它們），則動詞應為原形，不做改變。
