情境应用
1. —Could you tell me the of the sweater?
—Yes. It’s 125 yuan.
A.colour
B.price
C.shape
D.size
答案
B
解析
根据答语“It's 125 yuan.”可知问句是询问毛衣的价格，结合所学的“the price of...”表示“……的价格”的用法，A项colour意为颜色，C项shape意为形状，D项size意为尺寸，均不符合语境，只有B项price符合题意。
2. — the price of these trousers?
—98 yuan.
A.How much is
B.How much are
C.What is
D.What are
—98 yuan.
A.How much is
B.How much are
C.What is
D.What are
答案
C
解析
英语中询问价格有两种常用表达：1. How much + be动词 + 物品；2. What is the price of + 物品。本题空格后已有the price of结构，不能用How much引导，排除A、B；主语the price是单数，对应的be动词用is，排除D，因此选C。
1. The shop in front of our school all kinds of stationery(文具). (sell)
2. Today these pens are in the store. They are cheaper than usual. (特价销售)
2. Today these pens are in the store. They are cheaper than usual. (特价销售)
答案
1. sells 2. on sale
解析
1. 第一题考查一般现在时的主谓一致，句子描述客观事实，主语The shop是第三人称单数，谓语动词sell需要变为第三人称单数形式sells。2. 第二题考查本单元要求掌握的固定短语搭配，表达“特价销售”的常用英文短语是on sale，符合句中“商品比平时便宜”的语境。

解析
本题是购物场景的情景交际题。逐一分析选项：A选项"How are you?"的回应通常是描述自身近况，不符合答句语境；B选项"What are these?"需要回答具体事物的名称，和答句不匹配；C选项"Are you OK?"是询问对方状态，不符合语境；D选项"Can I help you?"是商店服务人员常用的询问顾客需求的用语，正好对应答句中顾客说明自己想要买运动鞋的内容，符合情景。

A.special something
B.something special
C.anything special
D.special anything
A.special something
B.something special
C.anything special
D.special anything
答案
B
解析
本题考查不定代词的用法：1. something多用于肯定句，anything多用于否定句和疑问句，本句为肯定句，排除C、D选项；2. 形容词修饰不定代词时，需放在不定代词的后面，因此正确结构为something special，排除A选项。

答案
A
解析
