6. Work in groups.
(1)Can I help you 是服务行业从业人员主动向顾客打招呼的常用语，在不同的场合有不同的译法。顾客如果有需要，可回答“Yes，please. ”，然后说出自己的要求，顾客如果不需要，可回答“No，thanks. ”。
拓展：类似的表达还有“What can I do for you ”“May I help you ”“Is there anything I can do for you ”。
(2)I need a sweater for school. 意为“我需要一件上学穿的毛衣”。need此处用作实义动词，意为“需要”，后面可以跟名词、代词或动词不定式作宾语，在句中有人称、数和时态的变化；need也可用作情态动词，后跟动词原形，常用于否定句或疑问句中。
(3)It looks (look) nice.
look此处用作连系动词，意为“看上去，看起来”，其后常跟形容词作表语。
拓展：look作不及物动词，后接宾语时，与介词at 连用。
(4)当你决定购买某种商品(单数)时，用“I’ll take it. ”，购买复数商品时用“I’ll take them.”。其中I’ll 是I will的缩写形式。will是助动词，意为“将要”。
(5)You’re welcome. 意为“不用谢；别客气”。
拓展：类似的表达还有“That’s OK. ”“That’s all right. ”“Not at all. ”。
Step 4　Grammar Focus
1. Ask the students to read the sentences in pairs. Pay more attention to “How much is... ”and “How much are... ”.

How much，how much，how much is the blue hat
5 dollars，5 dollars，it’s 5 dollars.
How much，how much，how much are the black socks

当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. D　由答语中的“Yes，please. ”可判断，问句句意为“你要买什么吗？”故选D。
2. D　在购买某商品时，常用“I’ll take it/them. ”表示“我买下了”。
3. A　由答语中的red可知，问句是在询问颜色，应用what color提问。
4. C　由a pair可知第一个空应用第三人称单数形式is，后半句主语为two books，故第二个空用are。
5. B　由问句句意“我可以用一下你的尺子吗？”及答语中的“OK. (行，可以)”可知，B项(给你)符合题意。
6. D　need to do sth. 意为“需要做某事”，故选D。
7. D　a pair of意为“一双(副、对)”；two pairs of意为“两双(副、对)”。
8. D　由句中的fifty可知，后面的名词应用复数形式；woman作定语修饰可数名词复数时，本身也要变成复数形式。故选D。
Step 8　Homework
1. Role-play the conversation in 2e with your partner and remember all the useful expressions.
2. Remember the sentence structures in Grammar Focus.
