【答案】 sell 和sells的区别和用法?
sell是【动词原形】,用于【一般现在时】,但【主语不能是第三人称单数】.
sells是sell的【第三人称单数形式】,用于【一般现在时】,但【主语是第三人称单数】.
如:
They/ We/ You sell books to the students.
He/ She/ The bookstore sells books to the students. 追问: Mocky's selling,Mocky's selling,Mocky's selling in the store.Sells a pen,sells a ball.Sells a purse in the store.这里是不是因有主语Mocky是第三人称才用sells的?翻译时需要注意什么吗? 追答: Mocky's selling,Mocky's selling,Mocky's selling in the store. Sells a pen,sells a ball.Sells a purse in the store. =Mocky is selling,Mocky is selling, Mocky is selling in the store. Sells a pen,sells a ball.Sells a purse in the store. 正确。这里是因为主语Mocky是第三人称才用sells的。翻译时【不需要注意什么】。 前面Mocky's selling是第三人称单数【现在进行时is selling】
