A.twice the size of that one B.twice as a large town as that C.twice as larger as that one D.twice as larger a town as that 解析：句意为：当你研究当地的地图时，你会发现这座城镇是那个的两倍大。倍数的表达方式：A is +倍数+the+名词(如size/length)+of B;B项中不定冠词位置错误;C、D项中as后应用形容词原级。 答案： A 2. Peter’s jacket looked just the same as Jack’s, but it cost ________ his. A.as much twice as B.twice as much as C.much as twice as D.as twice much as 解析： 倍数表达法是形容词比较等级中一种很常用的比较级结构。不管用哪种比较级结构来表示比较，表示倍数的词总是放在比较级结构的最前面。 答案： B 3. My uncle’s house in the downtown area is much smaller than ours，but it is twice_ _______expensive. A.as B.so C.too D.very 解析： 考查倍数表达法。这里的倍数是“twice”，由expensive这一原级可知，这里使用了“as...as...”这一比较结构，在具体的语境中，后面的一个as以及后面的成分可以承前省略，即这里expensive后面省略了as ours。 答案： A
【考点二】形容词、副词的比较级和最高级1.“as+形容词+(a/an)+名词+as”表示同级比较，注意中间的形容词和名词并列时各自所在的位置。 It is generally believed that teaching is as much an art as it is a science. 人们普遍认为，教学是一门科学，同时也是一门艺术。 2.“as+形容词/副词的原级+as”与“not as/so+形容词/副词的原级+as”表示同级比较，即两个或两部分人或物在性质上或程度上相同(不同)。 The work is not as/so difficult as you imagine. 这项工作不是像你想象的那么难。 3.“the+比较级+of the two +名词”表示“两者中较……的那个”。 The taller of the two boys is my brother. 两个男孩中较高的那位是我哥哥。 4.a+形容词比较级+n.…… After two years’ research，we have a far better understanding of the disease. 研究两年之后，现在我们对这种病有更好的理解。 We went to the USA in search of a better life. 为了寻找更美好的生活我们去了美国。 5.比较级的修饰语常见的有：rather，much，still，even，far，any(用于否定句或疑问句)，a lot，a little，a great deal，by far，a bit 等。 The students study even harder than before. 学生们学习比以前更努力了。 A car runs a great deal faster than a bike. 汽车比自行车跑得快得多。 6.最高级 (1)最高级的修饰语常见的有：序数词，by far，nearly，almost，by no means，not really，not quite，nothing like。 The bridge being built now is by far the longest across the Yellow River. 目前正在建的那座桥是横跨黄河之上的桥当中最长的桥。 I’d like to buy the second most expensive camera. 我想买仅次于最贵的照相机。 (2)否定词+比较级=最高级。 There is no greater love than that of a man who lays down his life for his friends. 为朋友而放弃生命的人的爱是最伟大的爱。 —Are you satisfied with what he said at the meeting? ——你对他在会议上说的满意吗? —No. It couldn’t have been worse. ——不，不能再差了。 【经典考题】1.

A.a way as good B.as a good way C.as a way good D.as good a way 解析： 考查固定短语。as...as表示“和……一样”，固定表达方式有“as+adj./adv.+as”“as+adj.+a/an+n.+as”等。 答案： D 2. —Do you think that the 11th Chinese National Games were a success? —Yes，________!It couldn’t be ________. A.relatively;better B.approximately;worse C.absolutely;better D.fortunately;worse 解析： 本题考查副词和形容词在语境中的运用。relatively 相对地，比较地;approximately 大约;absolutely 当然是，绝对正确;fortunately 幸运地。根据语境知，第十一届全运会绝对是一个成功的盛会，没有比它更好的了，故C项正确。 答案： C 3.
