SANDWICH SUCCESS

Britain's sandwich business is expanding fast. Half the population buy sandwiches at least twice (29) week, and they are spending more (30) them. (31)
sandwiches are made at home, while (32) from shops are selling in growing numbers.
One reason is that packaging keeps sandwiches fresh for up to 48 hours, making (33)
possible to mass-produce them centrally and distribute them widely. (34) reason is that petrol stations, wanting to expand the range of (35) they sell, have quickly become major outlets for sandwiches.
The increase in sandwich sales has also been helped by changing social trends. Many people have stopped (36) family meals at home, and (37) choose the time and place to eat. Time has become more important than price, (38) convenience is the most important reason (39) all.
Taken together, these changes are making the sandwich industry (40) into a very valuable business.

【正确答案】 C

【答案解析】[精析] 此题要通读全句才可得出答案，句中两个部分形成对比，“in growing number”说明商店的销售数量成增长趋势，相应的，家庭自制的数量在减少，所以fewer为最佳选择。故选C。

【正确答案】 C

【答案解析】[精析] 此题要注意指示代词的用法，these和those作指示代词，可代指前面提过的事物，此处these指代sandwiches。故选C。

【正确答案】 A

【答案解析】[精析] 此题意在考查指示宾语it的用法。形式主语和宾语的使用都是为了简化语句。之所以用it代替是为了避免头重脚轻。如I think it isinteresting to dance，真正的宾语是to do形式，it是形式宾语。此处真正的宾语是mass-produce them centrally and distribute them widely。故选A。

【正确答案】 A

【答案解析】[精析] 此题难度不大，与前面的one reason对应，陈述第二点时用another，但值得注意的是the other是用于两者之间，而another用于三者或三者以上。故选A。

【正确答案】 C

【答案解析】[精析] 此题考查的是以wh-疑问词来引导的名词性从句，the range of后面需跟名词，that，which都是引导关系从句，所以被排除。故选C。

【正确答案】 B

【答案解析】[精析] 此题又是考查固定搭配的一题。需要区分stop doing和stop to do，stop doing是指停止做某事，stop to do是指停下来去做某事。此题所在句的意思，人们不再在家中用餐，所以后面要跟doing。故答案为having。故选B。

【正确答案】 B

【答案解析】[精析] 此题要在充分理解此句的基础上来选择，在家用餐和在饭店用餐是两个取舍项，而A项also和c项alternatively都是含有兼而有之的意思，只有B项符合题意。故选B。

【正确答案】 C

【答案解析】[精析] 句中解决问题的关键点在两组词：more important，the most important，两者有转折递进的关系，故选although．故选C。

【正确答案】 A

【答案解析】[精析] 此题的着眼点在all，all实际为all reasons的缩略形式，所以句子的完整形式为the most important reason of all the reasons．of表示一种所属关系。故选A。
