课文详注 Further notes on the text
1．writing paper, 信纸。
paper意为“纸”、“纸张”时是不可数名词，一张纸应是 a sheet of paper或 a piece of paper。类似的名词还有：glue(a bottle of glue一瓶胶水）；chalk(a box/piece of chalk一盒／枝粉笔）；ink (a bottle of ink一瓶墨水）。
boxes后省略了 of chalk。
3．Do you want one? 您要一盒吗？
one代替 one small box of chalk。
4．What else do you want? 您还要什么吗？
What else…? 可以看成是表示疑问的一个句式，意思是“还有什么……吗？”else常接在疑问代词、不定代词及疑问副词后面，表示“此外”、“别的”、“其他的”。又如：
Who else is from New York? 还有谁是从纽约来的？
When else shall we meet again? 什么其他的时间我们再见面？
What else did he say? 他还说了些什么？
语法 Grammar in use
have当“拥有”讲时，可用于所有的一般时态，却不能用于进行时态（is having, are having等）。
