5. 虚拟语气

虚拟语气,又称假设语气,用以表示所述内容并非事实, 而只是一种假设、愿望、建议而已。一般有以下几种情况:

5.1 虚拟语气在非真实条件句中的应用

在非真实条件从句中的动词虚拟语气可分为三类:(1) were 型(表示与现在事实相反); (2) should be 型(表示与将来事实相反);(3) had been 型(表示与过去事实相反)。如果将这类条件从句中的w ere、should、had 提前置于句首,则可将连词 if 省略而成为不完全省略句。

要是病人能听从医生的劝告,早就应该复原了。

5.2 were 型虚拟语气可用于wish 后接的宾语从句中表示动作不可能实现或实现可能性不大;也可用于 as if、as though 引起的方式状语从句,表示并非真实情况。

但愿我年轻些。

5.3 should be 型虚拟语气在其他从句中的应用

should be 型虚拟语气可用在主语从句中,常见的句型有:It is necessary that,It is recommended that,表示“建议”、“要求”、“必须”做的事。从句中的 should 有时可省略。

6. what 引起的名词性从句

what 常可用来引起主语从句、宾语从句和表语从句。但应注意what 引起这几种从句时有两种情况。

(1) what 用作疑问代词性的连接代词,what 表示的是一个问题,应汉译为“什么”、“什么样的”,有时也可不译出。

(2) what 用作关系代词性的连接代词,意义相当于 that which (those which) 或the thing which、the man (men) who,可以译为“所……的(事物)。”

7. It 作形式主语的句型当动词不定式、动名词或从句作主语时,通常把它们放在谓语之后,而用一个引导词 it 放在句首,作形式主语。此处的 it 没有实际意义,可以省略不译。

“too + 形容词或副词 + 动词不定式”这种句型是“太……以至不能……”的意思。如果“too…to…”结构中有否定词或 but、only 时,句中不定式所表示的就是肯定意义,but too、only too 可译为“非常”。
