探究案
语法专项:
一.大数的表达与朗读:1000以上的基数词的表达法:先从右至左数,每三位数加一个逗点(即以此把数目分为若干段)。第一个逗点前的数为thousand(千),第二个逗点前的数为million(百万),第三个逗点前的数为billion(十亿)。
注:1. 英语没有“万”这个单位,要表示“万”需借用thousand,如“一万”用“十个千”表示(ten thousand),“十万”用“百个千”表示(one hundred thousand)。
2. 在thousand后通常加上连词and。若读数中没有hundred,则在thousand后加and。
【教材典句】1. 大约960万平方千米 about 9,600,000 square kilometers in size
2. 1025米深 1,025 meters deep 3. 6671千米长 6,671 kilometers long
4. 8848.43米高 8,848.43 meters high 5. 重5000千克 weigh 5,000 kilos
二.形容词和副词的比较级和最高级
(一)概说:英语中的形容词和副词有三个等级,即原级、比较级和最高级。比较级主要用于两者比较,最高级主要用于三者或三者以上进行比较。
(二)比较等级的构成:1. 通过加后缀-er和-est构成。①单音节和部分双音节词通过加后缀-er和-est构成比较级和最高级:tall-taller-tallest fast-faster-fastest ②若原级以字母e结尾,则只加-r和-st:fine-finer-finest ③若原级以“辅音字母 +y”结尾,则应将y改为i,再加-er和-est构成比较级和最高级:dry-drier-driest ④若原级以重读闭音节结尾,且末尾只有一个辅音字母,则双写这个辅音字母后加-er和-est构成比较级和最高级:big-bigger-biggest
2. 通过在其前加more和most构成:多音节和部分双音节词通过在其前加more和most构成比较级和最高级:difficult-more difficult-most difficult popular-more popular-most popular
助记:比较级的变化规则:比较等级要变化,一般词尾加-er;词尾若有哑音e,直接加r就可以;一辅重读闭音节,辅音字母要双写;辅音字母加y结尾,要把y改i加-er。
(三)形容词与副词比较等级的不规则变化:常见不规则形容词与副词的比较等级变化:
good/ well-better-best bad/ badly/ ill-worse-worst many/ much-more-most little-less-least
far-farther/ further-farthest/ furthest old-older/ elder-oldest/ eldest
(四)使用比较等级应注意的几点:
1. 使用比较等级的基本原则:不作比较用原级,两者比较用比较级,多者比较用最高级。
2. 在形容词的最高级前通常用the,在副词的最高级前可用the,也可省略。
3. 比较级前常用的修饰词语有far, even, a lot, a bit, much等。

1. 世界上最高的山是什么? What’s the highest mountain in the world?
2. 登上是世界上最危险的运动之一。One of the world’s most dangerous sports is mountain climbing.
3. 这头大象比这只大熊猫重许多倍。This elephant weighs many times more than this panda.
