As is shown in the picture, there is a cobweb-like structure with separate compartments packed in it.
Alice works as happily as (she) plays (happily).
He was as handsome as his wife was beautiful.
老师,as是作主语,句子中是什么词性;packed in it是分词作定语吗?as..as的结构,多数单面是介词,后面的as是连词是吗?
As is shown in the picture, there is a cobweb-like structure with separate compartments packed in it.
这个句子中的as传统语法认为(准)关系代词,引导非限制性定语从句,as的先行词(其实这时该叫作“后行词”了)是主句内容,as具有比较意义,翻译为“正如..."。
packed in it是过去分词,在with复合结构中作宾补,不是定语。
Alice works as happily as (she) plays (happily).
第一个as是程度副词,第二个as为引导比较状语从句的从属关联词。从句常省略与主句相同的句子成分。这个句子中as在从句中作方式状语,因此不可再重复happily。重复为语法错误。
He was as handsome as his wife was beautiful.
本句的比较是在不同主语的不同性质之间作比较,两个主语各自在某个性质上达到相同的程度。即如果丈夫的”英俊“能打90分,妻子的”漂亮“也能打90分。第一个as是程度副词,第二个as是引导比较状语从句的从属关联词,as在从句中程度状语。as在引导比较状语从句时,必须在从句中作成分,因此严格讲,as不是连词(连词不作成分)。我给它起名叫比较代词或比较副词(没有其他人这么称呼,但我认为正式最准确的名称---引导比较分句,同时在从句中要作成分)。
