主谓宾:主要看主语是否为第三人称单数
主语非第三人称单数(I,you,we,they),谓语不变
I work every day.
变疑问句:句首加do
Do you work every day?
变否定句:谓语动词前加do not(don't)
I don't word every day.
主语是第三人称单数(She,he,it),谓语就要变成第三人称单数格式
She runs every day.
He bakes beef every day.
My leader runs every day.:My leader是说的别人,并且还是单数,所以也是第三人称单数格式.
变疑问句:句首加does,谓语变原型
Does she run every day?
变否定句:谓语动词前+does not(doesn't),谓语变原型
Jack doesn't like Lily.
频度副词:often,never等
主系表放在be后面:I am often late.
主谓宾放在主语后面:I often run.
频度副词属于时间状语.英语只能有一个时间状语
I always eat bread every day.(x)
I always eat bread in the morning.
