shall
是情态助动词,即为主动词提供更多信息。
shall
往往涉及必然性(Certainty)、必要性(Necessities)、主动提议,在时态上指向未来。
有必要提下shall
的起源,以方便区分很多"古怪"的结论。
shall
最早起源于 17 世纪(英式英语)。
当时它被用来替换will
,当主语是第一人称(I
, We
)时。
这一直接对应转化在现代英语中已经很少见,可以认为已经过时。
反而,在现代英语中,特别是美式英语中,多用will
代替shall
,如涉及不那么正式、语气不特别强烈的必然性时。
当然,shall
依然有它的独自的使用场景:
1. 涉及语气强硬的必然性、必要性,如带保证、下决心、命令、警告、允诺、威胁。
2. 涉及内容正式的必然性、必要性,如规章、法令。
3. 由第一人称发起的带主动提议的疑问句。
当前Great|Wall
可数。
Should it rain tomorrow, we should have to put off the visit to the Great Wall.
这是一个简单句,可以扩展成分让它变得复杂。
句子类型是陈述句,其时态可以是一般过去时、一般过去将来时、一般现在时、一般将来时。
should
的特殊性有关。we
主语
should have {to do.}
谓语动词短语(复合结构)
to put off ••• Wall.
to do.
Should it rain tomorrow,
