The woman first bought a few small articles 可以看出，只有c. buy a few things 与课文的实际情况相符。
a. every Monday 这个妇女总是星期一去大商场，这是事实，但这不是侦探当时看到的情景。
b. pay the assistant for the dresses 和 d. put the dresses in her bag 都与课文的实际情况不符。
2. c根据课文第10-11行…the detective found out that the shop assistant was her daughter 可以判断出只有c. She was related to one of the assistants是为什么这女人能很容易地偷窃的原因，其他3个选择都不是她偷窃成功的原因，所以应该选c.3. c只有选c. less 才能使这个句子同前一句People are not so honest as they once were的含义相同。
其他3个选择都不正确：a. as 和 d. fewer 不合乎语法，意思不通；b. so 词意思也不对，不合乎题目意思。
4. b前一句用了比较级…fewer… than usual，本句只有选b. not as many as usual 才能同前一句的比较级意思相吻合。

a. chosen 是过去分词，不能用于一般过去时中；b. chose 是过去式，本句已经有助动词did 提问了，故不能用动词的过去式；d. choosing 为现在分词，不能用于一般过去时做谓语动词；只有c. choose 是动词原形，应该用在一般过去时疑问句中做谓语动词，所以选c.7. a只有 a. in 强调地点“在……里面”最合乎题目意思。
b. of 强调所属“……的”，不如a 正确；c. from 不合乎题目意思；d. to 强调方向，一般不能引导定语的短语。
8. da. looked要与介词连用才能带宾语，因此不能选a;b. looked for 与前一句中的watched 意思不符；c. looked after 也与watched 的意思不符；d. looked at 最接近watched 的含义，所以应该选d.9. a只有a. things同前一句中的articles意思相接近,所以只能选a.b. pieces,c. bits,d. parts这3个词都同articles 的含义不同.10. da. papered,b. turned,c. enveloped,d. made a parcel of ,只有 d同前一句的 wrapped的意思相同,而其他3个词意思都不对，所以选 d11. b只有b. was caught同前一句中的was arrested 意思相同。
