5) B为正确答案。
6) C错。应改为比较级cheaper。比较级后并不一定跟接连词than，有时在其间有名词或名词短语(被形容词所修饰)，介词短语，不定式或其他成分隔开。
7) A为正确答案。“She”作为单个不能跟全组比(C和D不对)，也不能跟全组所有相比，因为“她”也是其中一员，自然“她”不能跟自己相比。这里“She”比较的是“这组中的任何一个”，所以A对。
8) B错。应改为比较级later，因此处实为与1905年相比晚15年，故应使用比较级。 9) D为正确答案。 10) A为正确答案。
11) D错。 改为his master’s。 12) A错。 改为most。
13) C错。改为the， significant是多音节形容词，在此处应用最高级形式(在前面加 the most)，注意句中的“of all… ”。
14) C为正确答案。本句空白处缺状语，A和B全为名词短语，不符合条件；D为句子，和空白后面的句子没有任何联系，故亦应排除。只有C正确，和后面的最高级the most familiar前后呼应。 第四节 形容词和副词的特殊表达法
一、形容词与副词的同级比较： 由“as(so)…as”引出，其否定式为“not so…”或“not as…as”,考生还应注意下列含有“as”结构或短语的句子 1. as such：表示上文所指明的事或人
He is a child,and must be treated as such. 他是个孩子，必须被当作孩子对待。
2. as much：表示“与…同量”
Take as much as you like. 拿多少都行。
I would gladly have paid twice as much for it. 就是价格再贵一倍，我也会愿意把它买下的。
He as much as admitted the whole story. 他几乎全部承认了。 3. as many：表示“与…一样多”
I found six mistakes in as many lines. 我在六行中发现了六个错。 二、表示“几倍于”的比较级：用twice (两倍)，four times (四倍)，ten times (十倍)加上as … as 结构
This one is four times as big as that one. 这个是那个的四倍大。(这个比那个大三倍。) / Our campus is three times as large as yours. 我们的校园比你们的大两倍。 / He has books twice as many as she does. 他的书比她多一倍。

free的意思是\免费\；freely 的意思是\无限制地\

形容词使用顺序巧记忆
当两个以上形容词修饰一个名词，形容词该如何排列? 为什么不能说a black new pen，而要说成a new black pen? 这里面有无规则可循?
如果你记住Opshacom这个为帮助记忆而杜撰的词，就能掌握英语中形容词排列的顺序。
Opshacom中op代表opinion，指表示人们观点的形容词，如beautiful，horrible，lovely，nice等；
sh代表shape，指表示形状的形容词，如long，short，round, narrow等；
a代表age，指表示年龄、时代的形容词，如old，new， young等； c代表colour，指表示颜色的形容词，如red,black, orange等； o代表origin，指表示国籍、地区的形容词，如British，Canadian，German等；
m代表material，指表示材料的形容词，如plastic，metal，aluminium等。
英语中这六类形容词连用时就按上述先后顺序排列，如a nice long new black British plastic pen当然，实际语言使用中不可能出现这么多形容词连用的情况。
