often后用动词一般使用一般现在时态。often前的主语是复数形式,后面的动词使用原型;often前的主语是单三形式,后面的动词变成相应的单三形式。
另外当often前面的主语是I或者We 时,后面的动词为动词原形。
举例:
They often go to work by bus.他们经常乘公交去上班。
He often goes to school by bike.他常骑自行车上学。
We often go there.我们常去那里。
扩展资料:
习语:
1.as often as not
more often than not

2.every so often

3.once too often侥幸难再
举例:
You've tried that trick once too often.
你故技重施,可这次再逃不脱了。
often后用动词一般使用一般现在时态,后面的动词根据主语的形式而发生变化。当主语是单三时,后面是动词的单三形式。
当often前面的主语是I 时,后面的动词为动词原形。如果often前面的主语是单三形式时,后面的动词也同样是单三形式。如果often前面的主语是复数形式,那么后面的动词就是动词原形。
举例:He often goes to school by bus in the morning. 他经常早上乘公交去上学。
举例:I often go to school by bus. 我经常乘公交去上学。
举例:They often go to wok by bus.他们经常乘公交去上学。
但是我认为后面不用s
追答单三不一定是加S,比如He watches tv everyday.
追问难道是时态问题
追答这是在一般时态的,过去氏将来氏进行时肯定不一样的,还有be动词
包括情太动词should等
