when listening to the music.比较级的用法 :1.双方比较，表示一方超过另一方时，用 “比较级
+than”的结构表示。例如：
2.表示一方不及另一方时，用“less+原级adj./adv. +
than”的结构表示。例如：This book is better than that one.This room is less beautiful than that one.这本书比那本书好。这个房间不如那个房间漂亮。
Conclusion:
形容词比较等级的用法有哪些？
3.表示一个方面随另一个方面的程度而变化时，用
“the +比较级（+主语+谓语），the +比较级（+主
语+谓语）”的结构。
例如：
The harder he works, the happier he feels.The harder you study, the more knowledge you will get.他工作越努力，他觉得越快乐。你学习越刻苦，你学到的知识就越多。4.表示自身程度的改变“越来越……”时，用“比较
级+and+比较级”结构表示。例如：The weather is getting colder and colder. The little girl becomes more and more beautiful.天气变得越来越冷。这个小女孩变得越来越漂亮。“比较”出来的英语A friend is easier lost than found.Doing is better than saying.Two heads are better than one.Better to do well than to say well.Enough is as good as a feast.朋友易失不易得。会说不如会做。二人智慧胜一人。说得好不如做得好。知足常乐。就你不知道。Underline the comparative expressions and circle the adverbs used to give more information about the comparative expressions. 1.Come a bit closer.2.We need rather more than that.3.It weighs a little more than before.4.It’ll be a lot heavier than magnesium.5.Is it any heavier?6.We need a piece which is (very) much bigger than that. 比较级的修饰语：
在比较级的前面可以加上如下一些表示程度的状
语，但要注意其含义的差别。
a) any加比较级, 表示疑问程度，意为“……一些”，
“……一点”。例如：
b) no/not (any)加比较级, 表否定程度，意为“并不”。
例如：Are you feeling any better?Some grow no higher than your ankles.你感觉好些了吗？有一些长得并不比你的脚踝高。c) a bit, a little, slightly加比较级, 表示“稍微，一点
（些）”。例如：
d) much, a lot, greatly, (by) far, rather, a good (great)
deal等加比较级, 表示“……得多”。例如：May I stay here a little longer?
This problem is a bit more difficult than that one.The people here are a great deal richer now than before.我可以在这里多待一段时间吗？这个问题比那个要难点。现在这儿的人比以前富裕多了。【点津】
by far通常用于强调最高级。用于比较级时，一般放
在比较级的后面，如在前面，应在二者中间加“the”。
例如：He is taller by far than his brother./ He is by far the
taller of the two brothers.他比他的弟弟高得多。e) even, still加比较级, 表示强调，意为“甚至更/还要
……”。例如：
f) “数词+名词+比较级”表示确定的程度。例如：
He is five years older than I.
I got up an hour earlier than the others.
He gets even stronger.
Jack is tall, but Tom is still taller.他变得甚至更加强壮。杰克很高，但汤姆更高。他比我大五岁。我比其他人早起一个小时。The old woman is twenty times as

is 60 years old. We can say: 总结：倍数的表达
1.A+be+倍数+as+形容词原级+as+B
2.A+be+倍数+形容词比较级+than+B
3.A+be+倍数+the+性质名词+of+B性质名词：size，weight，width, depth，length 等注意：倍数要放在前面
【即学即练】 2.36m1.26mMongol is about twice as
tall as the superman. Mongol is about twice the

than the superman.At a rough estimate（估计），Nigeria is ＿＿Great
Britain.
A. three times the size as B. three times as the size of
C. three times the size of D. the size three times of
【解析】选C。本句考查倍数的表达。句意：据粗略估
计，尼日利亚面积是英国面积的三倍。依据倍数表达
的三种表达形式可知C 为正确答案。使用形容词、副词的比较级时要注意的几个问题：⑴在as…as 之间只能使用原级形容词（副词）。例如：
误：I have as less money as you do.
⑵切忌采用双重比较
比较级前可以用表示程度的修饰语来表示强调或程度，
但不可用more加比较级形式。例如：
误：His health is more worse than before.正：I have as little money as you do.正：His health is much worse than before.⑶应避免自我比较
使用比较级时，进行比较的双方必须是互相分离、
互不包含的独立概念或事物，否则比较就不合逻
辑。例如：
误：Bamboo probably has more uses than any
plant in the world.正：Bamboo probably has more uses than any
other plant in the world.【点津】比较的另一方如果是不定代词anyone,
anything, 前面不能加other, 而要在其后加else。但
是，若比较的双方不属于同一范围，句中则不加
other。例如：She runs faster than any boy in her class.She studies harder than anyone else in her class.她比班里其他人学习都刻苦。她比班里任何一个男生跑得都快。⑷ 表示“两者中较……”时，比较级前要加the。例如：(5) 连词than后使用代词 , 主格和宾格有时意义不同。
例如：The older of the two noblemen took a light and led
me into a back room.① I know you better than he.
我比他更了解你。
② I know you better than him.
我对你的了解比对他的了解更透彻些。这条河是那条河的三倍长。(倍数的表达）
2. 比较级+and+比较级
the+比较级，the+比较级 (1)This river is three times as long as that one. (2)This river is three times longer than that one. (3)This river is three times the length of that one.越来越……越……越……【解析】选D。句意：许多人已经捐献了那种血型的

度副词far修饰形容词比较级，放于比较级前。4. Mr. Stevenson is great to work for — I really
