1、译林版八年级上册Unit1导学案1、 比较级和最高级知识点回顾1. 比较级： （1）把一个人或物同另外一个人或物比较时，一方程度超过另一方，就需要用到形容词比较级。其结构是： A + be + 形容词比较级 + than + B. e.g. Jackie is taller than Alex, but Alex is heavier than Jackie. （2） 两者进行比较时，双方必须是同类的人或事，或者前后比较对象的性质要相同。 e.g. In winter, the weather in Guangzhou is warmer than Beijing.(判断正误，并修改)(注意：
2、双方进行比较时，为避免重复，后面的比较对象用that 或those代替，可以指人，也可指物。) e.g. It is more convenient to go there by bike than .(坐公交车) e.g. It took me more time to walk there than .(坐汽车)（3） 形容词的比较级前常可以用一些名词、数词、副词等修饰，反过来，在我们看到这些单词和短语时，其后的形容词则多用比较级。想想：这样的单词和短语有哪些呢？ e.g. Eddies English is much better than before. /The weather is
3、 getting warmer.（4） 表示“越来越”，说明本身程度的改变时，用“ ”或“ ”结构。 e.g. Our city is becoming more and more beautiful. /These years, he grows taller and taller.（5） 表示“越，（就）越”，说明一方随另一方的程度而变化时， 用 “ ”结构。 e.g. The busier my mother is , the happier she feels.（6） 并不是所有形容词的比较级后面都用than，当表示“是两者中较、更的一个”时，用“ ”结构。 e.g. This coa
4、t is more expensive of the two. (判断正误，并修改)（7） “more + 比较级”结构绝对是错误的！(比较下面两句话，判断正误) e.g. This computer is more older than that one. This computer is much older than that one. （8） 用比较级代替最高级，用“比较级thanany other可数名词单数”或“比较级thanthe other可数名词复数”或者“比较级+ than + anyone else”句型。 e.g. Max is taller than any othe
5、r boy in his class. =Max is taller than the other boys in his class. (注意：这里比较的范围都是in his class，想一想如果是不同范围的比较还可以用以上三种结构吗？)（9）不同范围的比较时，用“比较级thanany可数名词单数”结构。(判断下面两句话正误，并修改) e.g. Millie is taller than any boys in her class. Max in Class One is taller than any other boy in Class Two.2. 最高级：（1）三者或者三者以上的人
6、或物进行比较时，需要使用形容词的最高级。其结构是： A + be + the + 形容词最高级 + of / in /among+ 比较范围. (Note: 形容词最高级前面要加定冠词the) e.g. Jackie is the tallest in our class. （主语和比较范围不是同一属性） Jackie is the tallest of/ among all the students. （主语和比较范围是同一属性）（2）表示“A是最的一个”，用“A + 系动词 + one of 最高级名词复数 + 范围”结构。 e.g. China is one of the most ol
7、dest countries in the world. （3） 表示“在范围内，A是第几的”，用“A + 系动词 + the +序数词 +最高级 +名词单数 +范围”结构。 e.g. The Yangtze River is the first longest river in our country.（4） 表示“A、B or C，哪个/谁最？”用“Which /Who + 系动词 + the + 最高级，A，B or C？”结构。 e.g. Who is the heaviest, Kate, Lucy or Anna?
