Lesson 3
要点精讲

Look at this picture ！看这幅画！
I’m looking for my English book.我在找我的英语书。

How much money are they
问价钱时"money" 常省略。 如：
How much is this book
这本书多少钱？
（2）yuan是"元"的汉语拼音借用到英语中来的，对于英语来说它是外来语，因此单复数形式都是"yuan"。如：
I have 200 yuan now. 我现在有二百元了。
Can I help you 我能帮你的忙吗？（您想买什么？）
这是服务行业的工作人员向顾客说的第一句话。在 ( http: / / www.21cnjy.com )不同的环境可有不同的翻译。如在商店里可译成"您想买什么东西？"； 在车站、码头等处可译成"需要帮忙吗？"。在宾馆可译成"您要住店吗 "等等。这是很客气的表达方式。如：
—Can I help you 您想买什么？
