倍数的表示方法

解答：

解题思路： 见下解题过程： 倍数表达3法：记住无论哪种，必须把相差的倍数或百分比放在前面。 一、As……as……表比较的句型： A……＋倍数/分数/百分比＋as＋adj/adv＋as＋B （A、B代表2个被比较的事物或人）关键是记住必须把相差的倍数或百分比放在as……as的前面。 例：This road is twice as long as that one. (2005湖北卷)What a table! I’ve never seen such a thing before. It is__it is long. A half not as wide as B wide not as half as C not half as wide as D as wide as not half （C） 但是，在实际表达和考题中，这个句型经常有变形。变形情况如下： 1、 A……＋倍数/分数/百分比＋as＋adj＋n＋as＋B （02上海春季卷）American eat ___ vegetables per person today as they did in 1910. A more than twice B as twice as many C twice as many as D more than twice as many (D) （04广西卷）It is reported that the United States uses ___ energy as the whole of Europe. A as twice B twice much C twice much Dtwice as much (D) 2、 A……＋倍数/分数/百分比＋as＋adj＋a（n）＋n＋as＋B During the season all the animals are sold at twice as high a price as usual. 在这个季节，所有的动物的售价都是平常的2倍。 (NMET2001)It is generally considered that teaching is _____ it is a science. A an art much as B much an art as C as an art much as D as much an art as （D） 3、 A……＋倍数/分数/百分比＋as＋adj＋n（省略第2个as） The USA has more than 14 times as many people(as Australia). 美国的人口数量是澳大利亚的14倍还多。 （03上海卷）The house rent is expensive. I’ve got about half the space I had at home and I’m paying ___ here. A as three times B as much three times C much as three times D three times as much (D) 这里房租很贵。在家里住的一半大小的面积在这里要付2倍的价钱。后面省略了as at home。 二、…… 比较级+than…… A……＋倍数/分数/百分比/具体数字＋adj/adv的比较级＋than＋B This road is twice longer than that one. 这条路比那条长2倍。 He is two years older than I. 他长我2岁。 三、 A……＋倍数/分数/百分比＋the＋n＋of＋B （05上海卷）At a rough estimate, Nigeria is ____ Great Britain. A three times the size as B the size three times of C three times as the size of D three times the size of (D) 这个句型也有很多变形： 1） A……＋倍数/分数/百分比＋the/物主代词＋n He is double my age. 2） A……＋倍数/分数/百分比＋what从句 If you offered me six times what you have just offered, I would still take my pound of flesh. 如对本题解答还有疑问，可在“继续讨论”中留言，我收到后会尽快给你答复。谢谢你的配合！匆忙中难免有疏漏，请多包涵哦。我是菁菁草老师，随时为你答疑解惑! 最终答案：略
