What's that? It's a coconut. 询问某物是什么的句型： 句型结构 What's this/that? It's a/an+某物。 Mum,what's this?妈妈，这是什么？ It's a grapefruit.它是一个葡萄柚。 What's that? 那是什么？ It's a coconut. 它是一个椰子。 重点解析 what意为“什么”，this意为“这，这个”，that意为“那，那个”，它们是一组对应词。 询问距离说话人较近的物品时，用this来替代；询问距离说话人较远的物品是什么时，用that来指代。 生活实例 星期日，youyou和haohao去看昆虫标本展出，所有的标本都很漂亮，Youyou想知道自己面前的标本是什么，她该怎样询问呢？Haohao又是如何回答呢？ What's this？ It's a butterfly. 表示请求的句型——Can I...? 句型结构 问句：Can I+动词原形+其他？ 答语：Yes,you can. /No/Sorry,you can't. 重点解析 此问句用于向对方征求意见。属于情态动词型疑问句。此基本框架： 情态动词+人/物+动词原形+其他？ Can I have one？ can是情态动词，在一般疑问句中应放在句首，五人称和数的变化。 其后的谓语动词用原形。 在答语中，can't是can not的缩写。 生活实例 星期日，Ding ding做完家庭作业后，想和朋友们出去玩一会儿，于是他去征求妈妈的意见： Mum,can I go out with my friends? Yes,you can. 易混辨析 can 与may can与may都可以表示“允许；许可”。在征求对方意见时常may. May I go now? 现在我能走吗？ 在两者都可以使用时，may显得更客气一些。 May I take this seat?/Can I take this seat? 我能做这个座位吗？ 在陈述句中常用can. You can sit here. 你可以坐在这儿。 can还可以表示能力，而may则无此用法。 banana pineapple peach What's this? It's a/an.... What's this? It's an banana. What's that? It's a pear. What's this? It's a coconut. What's that?
