as简单之至的一个单词,用法却非常复杂.我会陆续分类收集整理,如果能对大家有所裨益,我将颇感欣慰.
as用法一.两种事物的同种属性进行比较,as中间是形容词或副词,结构如下:
事物A+谓语+as/so+adj(形容词)/adv(副词)+as+事物B
注:肯定句用as,否定句用as/so均可. 它们是adv(副词)用来修饰其后的adj(形容词)/adv(副词),as是连词用来连接事物B.
例句分析:
1.She is as beautiful as her sister. 她和她姐姐一样漂亮.
造句步骤1.先写句子 她漂亮 She is beautiful.肯定句在形容词前加as,所以句子为:She is as beautiful.
步骤2.找比较对象她姐姐 her sister,并在其前加as,所以为:as her sister
步骤3.将1和2连起来完整句子为 She is as beautiful as her sister.
2.She doesn't study as/so hard as her sister.她不如她姐姐学习用功.
造句步骤1.先写句子 她学习不用功 She doesn't study hard. 否定句在副词前加as/so,所以句子为:She doesn't study as/so hard.
步骤2.找比较对象她姐姐 her sister,并在其前加as,所以为:as her sister
步骤3.将1和2连起来完整句子为
She doesn't study as/so hard as her sister.
