34、 年、1987 年、1988 年和 1989年商店的增减情况。 2说明发生这些变化的原因及发展趋势。 B New Stores/B （分数：106.00）_正确答案：()解析：B New Stores/B From the graph above, we can see that the years 1984 and 1989 had the same number of new stores. In the next two years, the number of new stores increased. And the three years between 1985 and 1987

35、 had the greatest number of new stores opening. But the number of new stores decreased dramatically between 1986 and 1989. We can see that 1986 was the year in which the greatest number of new stores opened. Back to 1985, we know that the number of new stores is 24, four times higher than that in 19

36、84. And the number in 1986 increased by 6 compared with the number in 1985. When it comes to 1987, the number is 3 less than the number in 1986. Its not too much. But the next year is much fewer than the previous year. Worst of all, there are only 6 new stores opened in 1989. The number is only one

37、fifth of that in 1986. Accordingly it is likely that there will be fewer new stores opening in the next year. How does it happen? Probably, there are two reasons for the fall of the new stores opening. The first one might be that in the early years the stores of fruits were quite few, so more and mo

38、re new stores of fruits were opened. But everything is limited. The year 1986 reaches the highest. That is to say, the number is more than enough. And the second reason could be that there are some super markets opened nearby. Obviously, stores can not compete with the super markets, whether in vari

39、ety or in price. So these are probably the reasons for why fewer and fewer new stores of fruits were opened.二、BPart Reading (总题数：10，分数：70.00)2.The passage gives a general description of the organic agriculture in the U.S.（分数：7.00）填空项 1:_ （正确答案：Y）解析：本题为主旨大意题。从各小标题就可看出，本文较系统地阐述了有机食品的界定，历史，所含成分的标准、生产加工

40、过程的特殊性、在经济总量中所占比例、与传统农业的区别等信息，符合题干的意思。3.The term “organic farming“ first appeared in 2000.（分数：7.00）填空项 1:_ （正确答案：N）解析：本题相应信息在第三段的第句“The phrase.published in 1940”，主要干扰信息可能来自第二段的第句，因为这一句中出现了“term”这个词，但这句话的意思是：USDA 于 2000年给“organic”这个词制定了全国标准。其实，“term”和“phrase”是近义的。4.Organic agriculture accounts for th

41、e biggest proportion of the American agriculture.（分数：7.00）填空项 1:_ （正确答案：N）解析：从第四段第二句“Although12.000 nationwide”可知，有机农业(organic farming)还只是一个小规模的行业(a small industry)。从第五段第一句“The USDAs.farmland”中也可得知，在美国八亿二千八百万英亩耕地中，只有一百三十五万英亩采用有机生产。由此可见，美国有机农业在整个农业中所占份额并不大。5.Organic agriculture is quite different fro

42、m the traditional one.（分数：7.00）填空项 1:_ （正确答案：Y）解析：第四个小标题下的内容就是对有机农业和传统农业进行比较。从中可见，有机农业和传统农业是有很大区别的。6.The use of the seal “USDA Organic“ is not required.（分数：7.00）填空项 1:_ （正确答案：Y）解析：本题相应信息在第五小标题下第二段第二句“As its use is voluntary，companies may choose not to display the seal”句中 voluntary一词的意思是：自愿的；不要求的。这与题

43、干中的 not required相符。7.Organic food differs from conventional food only in the way it is grown.（分数：7.00）填空项 1:_ （正确答案：N）解析：第七个小标题下第一段第二句“Organic food differsprocessed”告诉我们，有机食品和传统食品不仅在种植方式，还在处理、加工等方面有区别。第六个小标题下的内容也可佐证这一论断。8.America is the leading country in organic agriculture.（分数：7.00）填空项 1:_ （正确答案：N

44、G）解析：文章中提到美国的有机农业近年来稳步地发展，依据在第二个小标题下第二段的最后一句“Although it is still.nationwide”(从业人数每年以 12%的速度递增)，但并没有提到美国是否是世界上最大的有机食品生产国。9.USDA in this passage stands for 1.（分数：7.00）填空项 1:_ （正确答案：the National Organic Standards Board of the U.S. Department of Agriculture）解析：相应信息在第二段第一句。10.The leading producer of org

45、anic fruits and vegetables in 1997 was 1.（分数：7.00）填空项 1:_ （正确答案：California）解析：第三个小标题下第三段第一句“While organic foodof total yield”。11.Those foods labeled simply “organic“ must have at least 1 organic ingredients.（分数：7.00）填空项 1:_ （正确答案：95%）解析：该题的相关信息见第五个小标题下的第一段第五句“These food labeled simplyand salt”。由此可知，在标有“有机”字样的食品中，有机成分至少占 95%。三、BPart Listenin(总题数：1，分数：56.00)Questions 11 to 18 are based on the conversation you have just heard.（分数：56.00）A.Both editions are the same price now. B.The paperback is on sale.C.The hardcover book is better quality; therefore, it costs more.D.T
