1.(2011·福州模拟)When you study the local map,you’ll find this town is________.
the size of that one
as a large town as that
as larger as that one
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.(2009·辽宁卷)Peter’s jacket looked just the same as Jack’s,but it cost________his.
much twice as
as much as
as twice 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.(2009·四川卷)My uncle’s house in the downtown area is much smaller than ours,but it is twice________expensive.


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
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像的那么难。
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。
+形容词比较级+n.……
