当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. A　问句主语为the skirt，表示单数概念，be动词用is，答语用“It’s...”。
2. B　yuan没有复数形式，故A项错误；美元符号＄和人民币符号￥应放在数字前面，故C、D两项错误，故选B。
3. A　根据答语句意“10美元”可知问句是在询问物品的价格，应用how much“多少钱”。
4. C　询问表示单数意义的商品价格，用“How much is... ”；询问表示复数意义的商品价格，用“How much are... ”。连系动词be的单复数形式由所提问的名词单复数形式决定，由trousers可知选C。
5. D　前句中的trousers是复数形式，be动词用are；后句中的mine是指“my trousers”，故be动词还是用are。
Ⅱ. 1. socks　成双成对的物品一般以复数形式出现。a pair of socks意为“一双短袜”。
2. are　主语socks是名词复数形式，be动词用复数形式are。
3. shoes　成双成对的物品一般以复数形式出现。如：shoes，socks，shorts，trousers等。
