As引导的状语从句中的省略现象

Ellipsis in adverbial clauses leading with "as"

在英语中,为了使话说得简明扼要,英语句子中的某个、短语,甚至从句都可以省去。这种省去句子某些成分而保持句子原意不变的现象称为省略。在此文中仅对AS引导的状语从句中省略现象进行阐述。在由AS引导的时间、方式和比较状语从句中,如果(1)谓语中含有动词“be”,并且(2)从句中的主语和主句中的主语一样,(3)或者从句中的主语是“it”或者“they”,则主语或谓语中的部分(尤其是从句中的“be”)可以省去。

In English, in order to make a sentence brief and coherent, some words and phrases, sometimes even the main clause or the subordinate clause, can be omitted without changing the meaning of the sentence. This kind of omission is called ELLIPSIS. In adverbial clauses with time, adverbial clauses of manner, and adverbial clauses of comparison, the subjects or parts of the predicate (especially the verb 'be' of the subordinate clauses) can be omitted in the condition that (1) the verb 'be') is included in the predicate, (2) the subject of the subordinate clauses is the same as that of the main clauses, (3) or the subject of the main clauses is 'it' or 'they'.
