　　2）The experiment was____ easier than we had expected.
　　A. more　　 B. much more　　 C. much 　　D. more much

　　A. the happiest time　　　　 B. a more happier time
　　C. much happiest time　　　　D. a much happier time
　　答案：D。

　　重点难点详解

　　 many more +可数名词复数

- elder/eldest 只用于兄弟姐妹旳长幼关系。
　　 - My elder brother is an engineer.
　　 - Mary is the eldest of the three sisters.
　　3) far 有两种比较级，farther，further. 在英语中两者都可指距离。
　　 在美语中，father 表达距离，further表达深入。 I have nothing further to say.
　（2）the + 最高级 + 比较范围
　　1) The Sahara is the biggest desert in the world.
　　 形容词最高级前一般必须用定冠词 the，副词最高级前可不用。
　　 形容词most前面没有the，不表达最高级旳含义，只表达“非常”。
　　 It is a most important problem. = It is a very important problem.
　　注意： 使用最高级要注意将主语包括在比较范围内。
　　- (错) Tom is the tallest of his three brothers.
　　- (对) Tom is the tallest of the three brothers.

by far, far, much, mostly, almost - This hat is nearly / almost the biggest.

　　a. very可修饰最高级，但位置与much不一样。
　　 - This is the very best.
　　 - This is much the best.
　　b. 序数词一般只修饰最高级。 - Africa is the second largest continent.
　　3) 句型转换：
　　 - Mike is the most intelligent in his class.
　　 - Mike is more intelligent than any other students in his class.
　　4) “否认词语+比较级”，“否认词语+ so… as”构造表达最高级含义。
　　 Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing.
　　（3）和more有关旳词组
　　1) the more… the more… 越……就越…The harder you work，the greater progress you'll make.
　　2) more B than A = less A than B 与其说A不如说B
　　 He is more lazy than slow at his work. = He is less slow than lazy at his work.
　　3) no more… than… 与…同样…，不比…多 The officials could see no more than the Emperor.
　　 no less… than… 与……同样…… He is no less diligent than you.
　　4) more than 不只是，非常 She is more than kind to us all.
