四大条件句详解

条件句用于表示仅当一个特定条件(在if + 从句中)满足时,主句(不包含if的句子)中的动作才会发生。

通常有如下两种结构:

If + 从句+ , + 主句 + .
主句 + if + 从句 + .
  • If it doesn't rain, we'll go to the park.
  • We'll go to the park if it doesn't rain.
关于逗号
1. 如果if + 从句出现在整句开头,不要忘了在其后添加逗号( , )
2. 如果主句部分出现在整句开头,则无须使用逗号。
(添加逗号是为了避免在书面语中主从句划分异常引起歧义。而if + 从句后置时,if引导词本身就潜在划分功能,所以前面的逗号可以省略)
次序引起的强调
在书面语中,次序引起的强调效果不是特别明显。但在口语中,配合语气强弱,很容易起到强调作用
1. if + 从句在前,强调if + 从句,即强调条件
2. 主句在前,强调主句,即强调结果

英语中一共有四大类条件句,在接下来的小节中,让 Enpuz 为您逐个做详细介绍。

shall/should + do.

这是一个动词短语。

shall 与 should 有何区别

shall

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。

  • I shall be there on time. 我会准时到那。
  • You shall pass the exam. 你会通过考试。
  • Shall I close the door? 我需要把门关上吗?
起源

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。

  • I [shall/will] be there on time. 我会准时到那。

当然,shall依然有它的独自的使用场景:

1. 涉及语气强硬必然性、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。
