It is easier to make a plan than to carry it out. 序数词通常只修饰最高级。 Africa is the second largest continent. The Yellow River is the second longest river in China.This is the third most popular song of Michael Jackson.为避免重复，我们通常用that, those, one, ones代替前面出现的名词。that代替可数名词单数和不可数名词，those代替可数名词复数。one既可指人又可指物，只能代替可数名词。The weather in China is different from that in America.The book on the table is more interesting than that(或the one)on the desk.A box made of steel is stronger than one made of wood.误：In winter, the weather of Beijing is colder than it of Shanghai. 正：In winter, the weather of Beijing is colder than that of Shanghai. “否定词 + 比较级”相当于最高级。-Wait until we get a satisfactory reply, will you?-I couldnt agree more. The idea sounds great to me.Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing.比较级前一般不加冠词。但表示两者中较突出者，且比较级后又有名词或出现了of the two，这时比较级前一定要加the。 He is the taller of the two. Of the two jobs，he chose the harder. Which is the younger one, Lily or Lucy? 试比较：Which is larger, Canada or Australia? Which is the larger country, Canada or Australia? She is taller than her two sisters. She is the taller of the two sisters. 不含than 的比较级前可加不定冠词修饰，构成“a/an+比较级+单数可数名词”表示 “一个更的人/物”。Why dont you use a sharper knife? 你为什么不用一把更锋利的刀呢？比较级than 后应用人称代词的主格，但非正式语体中常用宾格。He is taller than I/me.为避免重复，比较级中同样的动词用助动词do, does, did替代。I spend less time doing homework than John does.She tells more funny jokes than we do.以下内容不是初中教学的重点，仅供拓展之用。形容词most前面没有the，不表示最高级的含义，只表示“非常”。 It is a most important problem. =It is a very important problem. 倍数表达法A is three(four, etc.)times the size(height, length etc.)of B.The new building is four times the size(the height)of the old one.这座新楼是那座旧楼的四倍大（高）/这座新楼比那座旧楼大（高）三倍。A is three(four, etc.)times as big(high, long, etc.)as B. Asia is four times as large as Europe. 亚洲是欧洲的四倍大/亚洲比欧洲大三倍。A is three (four, etc.)times bigger(higher, longer, etc.)than B.Your school is three times bigger than ours.你们的学校比我们的学校大三倍。用times表倍数通常用于三倍以上，两倍可以用twice或double.【教学反思】
