职称英语卫生类假设句型语法考点

  If + Present Tense ……, S + will/shall + V ……

  结构︰If+现在式…,S+未来式…

  说明︰if 子句用现在式,表示须具备的条件,主句用未来式表示可能的结果,整句含意为“如果…,那么…”。will 用于所有的人称,在 I 和 we 之后可用 shall 代替 will.若主句的主词为 I 或 we 时,可以用 shall 代替 will.像 if necessary(如果需要),if possible(如果可能),if so(如果这样)等固定词组实际上是省略了的` if 子句。

  If + Present Tense ……, S + Modal Verb ……

  结构︰If + 现在式,主词+情态助动词

  说明︰本句型实为句型之变体。之所以用情态助动词,主要是因为说话者对可能的结果不是太肯定或者是想表达例如必要的意思。

  If it is fine tomorrow, we must go out. 如果明天天气好,我门必须出门。

  If I should ……, Imperative Sentence.

  结构︰If I+should ……+祈使语气

  说明︰代替,增加了条件的不确定性。本句型常用在想礼貌地提出要求或建议,或者想圆通地告诉他人该做什么事的场合。用 should 起始句子即可不用 if 而表示条件。这种用法比较正式,常用于诸如公函之中,而不用于日常会话。

  Should you see him, please give him my regards. 如果你见到他,请代我向他致意。

  If I should ……, I will ……

  结构︰If…should…,…would(will)/should(shall)等+原形动词

  说明︰这是表示与未来事实相反的假设,if 要用 should,译成“万一”。should可置于前,将 if 省略。的则视可能性做变化:若可能性低,则为过去式,若可能性高,则为现在式。should 可以提前,而将 if 省略。

  If he should come, I will tell him the truth. 万一他来,我一定会把真相告诉他。
