重點解析
what意為“什么”，this意為“這，這個”，that意為“那，那個”，它們是一組對應詞。
詢問距離說話人較近的物品時，用this來替代；詢問距離說話人較遠的物品是什么時，用that來指代。
生活實例
星期日，youyou和haohao去看昆蟲標本展出，所有的標本都很漂亮，Youyou想知道自己面前的標本是什么，她該怎樣詢問呢？Haohao又是如何回答呢？
What's this？
It's a butterfly.
表示請求的句型——Can I...?
句型結(jié)構(gòu)
問句：Can I+動詞原形+其他？
答語：Yes,you can.
/No/Sorry,you can't.
重點解析
此問句用于向?qū)Ψ秸髑笠庖?。屬于情態(tài)動詞型疑問句。此基本框架：
情態(tài)動詞+人/物+動詞原形+其他？
Can I have one？
can是情態(tài)動詞，在一般疑問句中應放在句首，五人稱和數(shù)的變化。
其后的謂語動詞用原形。
在答語中，can't是can not的縮寫。
生活實例
星期日，Ding ding做完家庭作業(yè)后，想和朋友們出去玩一會兒，于是他去征求媽媽的意見：
Mum,can I go out with my friends?
Yes,you can.
易混辨析
can 與may
can與may都可以表示“允許；許可”。在征求對方意見時常may.
May I go now?
現(xiàn)在我能走嗎？
在兩者都可以使用時，may顯得更客氣一些。
May I take this seat?/Can I take this seat?
我能做這個座位嗎？
在陳述句中常用can.
You can sit here.
你可以坐在這兒。
can還可以表示能力，而may則無此用法。
