Britain's sandwich business is expanding fast. Half the population buy sandwiches at least twice{{U}} (29) {{/U}}week, and they are spending more{{U}} (30) {{/U}}them. {{U}}(31) {{/U}}
sandwiches are made at home, while{{U}} (32) {{/U}}from shops are selling in growing numbers.
One reason is that packaging keeps sandwiches fresh for up to 48 hours, making{{U}} (33) {{/U}}
possible to mass-produce them centrally and distribute them widely.{{U}} (34) {{/U}} reason is that petrol stations, wanting to expand the range of{{U}} (35) {{/U}}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{{U}} (36) {{/U}}family meals at home, and{{U}} (37) {{/U}}choose the time and place to eat. Time has become more important than price,{{U}} (38) {{/U}} convenience is the most important reason{{U}} (39) {{/U}}all.

【正确答案】 B
【答案解析】[精析] twice a week为固定搭配，搭配方法为…times a(one)…，比如once a month：three times a year．故选B。
【正确答案】 A
【答案解析】[精析] 此题要区分spend on sth和sDend in doing sth；them为代词。故选A。
【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。
【正确答案】 A
【答案解析】[精析] make后要跟动词原形，即make do sth，此处亦为固定搭配。故选A。
