預測一:虛擬語氣在 if 非真實條件句中的規(guī)則變化
非真實條件句表示的是假設的或實際可能性不大的情況,故采用虛擬語氣。
從句 | 主句 | |
與現(xiàn)在事實相反 | did/were | would (should/could/might) do |
與過去事實相反 | had done | would (should/could/might) have done |
與將來事實相反 | did/were; were to do; should do | would (should/could/might) do |
預測二:if 非真實條件句的倒裝
虛擬條件句的從句部分含有 were,should 或 had 時,可省略 if,再把 were,should 或 had
移到從句的句首進行倒裝。例如:
Were they here now, they could help us. = If they were here now, they could help us.
他們現(xiàn)在要是在的話,就會幫助我們了。
Had you come earlier, you would have met him. =If you had come earlier, you would have met
him. 你來得早一點,就碰到他了。
Should it rain, the crops would be saved. =Were it to rain, the crops would be saved.
假如下雨,莊稼就有救了。
預測三:錯綜時間條件句的虛擬語氣
有時,主句與從句的動作發(fā)生在不同的時間,主句從句謂語動詞的虛擬語氣形式因時間不
同而不同,這種條件句叫做錯綜時間條件句。例如:
If you had asked him yesterday, you would know what to do now. 如果你昨天問過他,今天就
知道做什么了。(從句與過去事實相反,主句與現(xiàn)在事實相反。)
If it had rained last night, it would be very cold today. 如果昨晚下過雨,今天就會很冷了。
預測四:含蓄條件句的虛擬語氣
有時為了表達的需要,在虛擬語氣中并不總是會出現(xiàn) if 引導的條件句,而是通過其他手段
來代替條件句。其主要表現(xiàn)形式如下:
用 with, without, but for, otherwise, or, under 等代替條件狀語從句。例如:Without water, there would be no life. 若是地球上無水,就無生命。
But for the meeting, I would have gone home at the time. 要不是開會,我早就回家了。
I was too busy at that time, otherwise, I would have called you. 我當時太忙,否則我就給你打電話了。
預測五:名詞性從句中的虛擬語氣
(1)It is demanded (requested/required/insisted/suggested/proposed...) /important (essential/
necessary/natural/imperative...) / a pity (a shame/no wonder...) + that... 等結構的主語從句,謂語動
詞用 should 加動詞原形,should 可省略。例如:
It is demanded that the president (should) make measures to end the economic recession.
人們要求總統(tǒng)應該采取措施阻止經(jīng)濟衰退。
It is necessary that he (should) go to see a doctor. 他應該去看醫(yī)生,這是必要的。
It is a pity that he (should) fail to come to the party. 他沒能參加這個聚會,真是遺憾。
(2)用于賓語從句中
在表示命令、建議、要求(如 demand, command, request, require, insist, suggest, propose,
order, recommend)等一類動詞后面的從句中,謂語動詞用 should 加動詞原形,should 可省略。
例如:I suggest that we (should) hold a meeting next week. 我建議下周召開個會議。
He insisted that he (should) be sent there. 他要求被派到那兒去。
注意:若 suggest,insist 用于其本意 “ 暗示、表明 ”“ 堅持認為 ” 時,賓語從句用陳述語氣。
例如:Your pale face suggests that you are ill./ I insisted that you were wrong.
(3) 在 demand/command/request/requirement/insistence/suggestion/advice/proposal/recom
mendation/idea/plan/order 等表示要求、建議和命令等名詞后面的表語從句、同位語從句中的動
詞要用虛擬語氣,即(should)+ 動詞原形。例如:
My idea is that we (should) get more people to attend the conference. 我的想法是讓更多的人來參加會議。
