摘要:  ——ed分词(一)   内 容 提 要   -ED分词即我们平常所说的动词过去分词。它有两种形式:规则动词形式和不规则动词形式。规则动词形式由规则动词+-ED构成;不规则动词有其特殊的-ED分词。在语法功能上,它在句子中所能承担的成分基本与-ING分词相同,可以作表语,定语,状语,也可以用在复合结构中,不管它作什么成分,其最基本的含义是“被动”的。-ED分词在语法功能和意义上与-ING分词有一定的区别。   第一节 -ED分词的用法   一、-ED分词作表语   The glass is br

d bonds.

  [A] earn [B] earned [C] to earn[D] was earned

  2) On his return from his college, he found the house .

  [A] deserting[B] deserted[C] desert[D] to be deserted

  3) The age [A] of a geological sample can be estimated [B] from the ratio of radioactive to nonradioactive carbon present [C] in the object is examined [D] .

  三、用作状语的-ED分词

  这样的-ED分词通常来自及物动词。-ED分词用作状语时,跟-ING分词作状语时一样,修饰主句的谓语动词,意义上相当于状语从句,表示时间,条件,原因,伴随状况等。-ED分词结构作状语,前边往往可以加when,while,if,as if,though.这时,我们可以把-ED分词结构理解为一个省略句,即省去了“主语和be的变化形式”。一般说来,这种结构的逻辑主语必须与主句的主语一致。
