My grandmother_____(exercise)every morning My sister often s_____ on the lake in winter 请说明一下理由,
My grandmother_____(exercise)every morning My sister often s_____ on the lake in winter 请说明一下理由,
【参考答案】
My grandmother 【exercises】 every morning.
My sister often 【skates】 on the lake in winter.
这两题都是一般现在时,由于主语是三单,故谓语动词使用三单形式.
有不理解的地方欢迎追问
exercises swims 都是第三人称单数形式啊请采纳
exercises 第三人称单数加s ，后面那个skates，冬天当然在湖上滑冰啦
exercises 第三人称单数加s ，后面那个skates 这道题考动词一般现在时 ，主语是单三动词加S或es 的变化
exercises ,skates ,都是经常的事，所以用一般现在时。主语是第三人称单数所以动词用第三人称单数形式
My grandmother exercises every morning. My sister often skates on the lake in winter.
都是第三人称单数。
exxercises，三单。skates，冬天湖会结冰，所以是滑冰，别忘了加三单。
