10．Americans 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 解析：　四个选项中，只有D项符合“倍数＋as many(或much)＋名词＋as...”这一结构，故应选D。 答案：　D 11．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：　句意为：我叔叔在闹市区的房子比我们(不在闹市)的房子要小的多，但是它的价格却是我们的房子价格的两倍：考生要从句子结构和意思上看出本句所省略了的部分内容，因此使用了表达倍数的as...as...的结构。 答案：　A 12．You’re driving too fast.Can you drive ________？ A．more slowly a bit B．slowly a bit more C．a bit more slowly D．slowly more a bit 解析：　考查副词的比较级。slowly的比较级是在其前加more，a bit修饰比较级放于前面，A、B、D三项在排列顺序上均有误，故应选C项。解决此类题时，首先根据句意确定所填内容意思，而后分析各词的关系和顺序。 答案：　C 13．________you consider，________you will feel. A．The many；the worried B．Much；much worried C．The more；the more worried D．Many；more worried 解析：　此处考查的是“the＋比较级，the＋比较级”这一句式结构。句意为“你考虑的越多，你就会越担心”。 答案：　C 14．—Are you feeling________better today? —No，I’m feeling________worse. A．by far；quite B．more；very C．fairly；rather D．any；even 解析：　疑问句中any修饰比较级，第二空用even修饰比较级，意为“感觉甚至更糟了。” 答案：　D 15．With time going by，he became________in the summer training. A．more and relaxed B．more and more relaxed C．more and relaxing D．more and more relaxing 解析：　句意为：随着时间的推移，他在这次夏季培训中越来越轻松。A项和C项这两种表达方式在英语中不存在，故排除；relaxing令人感到轻松的，通常用于修饰物；而此处表示人感到轻松，故选B项。 答案：　B * Section Ⅱ　Grammar 形容词和副词的比较级和最高级 用形容词和副词表示比较级和最高级的几个重要句型： 1．“比较级形式＋than”意为“比……更” That’s easier said than done.说比做容易。 It is much cheaper to post a long report than to fax it. 邮寄一份长篇报告比发传真便宜得多。 2．“...as＋原级＋as...”意为“和……一样” The building is as high as the tower. 这幢建筑和那座塔一样高。 This picture is as beautiful as that one. 这幅画和那幅一样漂亮。 What I did was as good as that of a normal person. 我所做的和一个正常人做的一样好。 3．“...not as/so＋原级＋as...”意为“不及……” Luckily the weather was not so/as wet as it is today. 幸运的是，那天天气没有今天潮湿。 My dictionary is not as/so useful as yours. 我的词典不如你的有用。 4．表示倍数的三个句型 (1)表示A是B的几倍时，主要有下面几种表达方式： ①倍数＋形容词(或副词)的比较级＋than ②倍数＋as＋形容词(或much)原级或副词原级＋as ③倍
