Part 3　Grammar for Writing 一、形容词和副词的同级比较 在上一单元中,我们学习了形容词的比较级和最高级,同时还了解到一些形容词是没有比较等级的。如果想运用极限形容词比较两者可以怎么做呢?这就是本单元我们要重点学习的内容:形容词和副词的同级比较。其主要结构是:as+形容词或副词原级+as…。 请阅读下面关于形容词和副词的同级比较的用法,注意其结构变化和所表达的意义,然后整理成思维导图。 建议用时:10～15分钟　　　实际用时:　　分钟 句型结构 意义 例句 as+形容词或副词原级+as　 表示前者与后者一样 •My handwriting is as beautiful as yours. •I can write as beautifully as you (do). as+形容词原级+名词+as　 表示前者与后者一样 •He is as naughty a boy as John. •He has as many friends as you (do). not as/so+形容词或副词原级+as 表示前者不如后者 •My mum felt not so happy as I did. •He did not come as/so early as Wang Lin. 倍数/分数/百分数+as+形容词或副词原级+as　 表示前者是后者的几倍/几分之几/百分之几 •My bedroom is twice as big as theirs. •The population of this city is two thirds as large as that of our city. as…as+含有数量的词组 表示强调其数量多 •Some of the stones weighed as much as fifteen tons. •He had played on computer for as long as three hours. as…as possible / as you can / as you like 表示尽可能……/ 尽你所爱 •Can you say it as loudly as possible? •You can take water as much as you like. as…as ever / usual / before 表示与往常一样 •My English teacher is as young as ever. •She worked as hard as before. 二、含有形容词和副词的级但不表示比较意义的情况 1.注意以下同级短语还具有特殊含义。 •as good as 几乎,实际上,无异。如:A miss is as good as a mile.失之毫厘,差之千里。 •as well as 除……之外(也)。如:She knows a little German as well as speaking English well.她英语讲得好,还懂得一点德语。 •as long as 只要。如:As long as I live,the bridge lives.只要我人在,桥就在。 •as far as 据……,就……而言。如:As far as I can see,you’ve done nothing wrong.依我看,你没有做错任何事。 2.注意以下比较级短语的实际含义。 •sooner or later 迟早,早晚有一天。如:If you drive like that, sooner or later you’ll have an accident.你如果那样开车,迟早会出事的。 •much less 更不用说,何况。如:The baby can’t even walk,much less run.这婴儿连走都不会,更不用说跑了。 •none other than(强调出人意料的人或事)竟然,正是。如:His first customer was none other than the President.他的第一位顾客竟然是总统。 •no more than只是,至多,只不过。如:It’s true we were acquainted,but no more than that.我们的确认识,但仅此而已。 •no more / no longer 不再,已不。如:He could stand no more and left.他无法再忍受,便走了。　　She could no longer afford to keep him at school.她已无法再供他读书了。 3.请比较下面两
