（usually）Jackislateforclass.

（never）Hegoestoschoolat7:00everymorning.

（always）Onweekends,myfathertakesustothemovies.

（sometimes）Mybrothergetsgoodgradesatschool.Iamproudofhim.

（often）除了模糊、精确频度副词，还有一些短语可以表示频率哦注意用every

day,every

week,every

Satuday,on

Saturdays 等频度副词短语表示频率。e.g.EverySaturday，Igotothe

park.=Igototheparkon

Sartudays.注意：EverySartuday在这里等于OnSartudays。因为every本身意思就是“每一”，为单数，所以不用加s。而on

Saturdays指所有的周六，为复数，所以要加Saturday词尾要加s。其他短语同理。再比如：e.g.OnSundays,Igotothecinemawith

Jack.=

，IgotothecinemawithJack.listento
