    AEIS寫作?虛擬語氣重點難點!

    發布時間:2021-08-19

      AEIS寫作是AEIS考試中的重難點之一,由于大部分學生都把注意力放在聽力與口語上,備考中難免有疏漏,今天我們就從文章結構、基礎語法等方面入手,為大家分析虛擬語氣重點難點!

      一、語氣

      1.陳述語氣:陳述一個事實或提出一種想法的語氣。I don’t know anything about the accident.

      2.疑問語氣:用來提出問題或詢問情況的語氣。Do you have a camera?

      3.祈使語氣:用來向對方提出請求,邀請,給予忠告,指示,警告,命令等的語氣。在祈使語氣中,直接用動詞原形,主語you一般省略。Come in and take a seat.

      4.虛擬語氣:表示一種假想或主觀愿望。If I were you , I would forgive Mary.

      二、虛擬語氣在條件句中的用法

      真實條件句

      這種條件句實現的可能性非常大,常用 If, unless, once, as/so long as, on condition that來引導。

      If I have time, I will go to America.

      Unless they invite me, I will not go to the party.

      虛擬條件句

      1.對現在情況的虛擬

      對現在情況的虛擬,條件句用一般過去時,主句謂語用“would/should/might/could+動詞原形”。

      If I were you, I would choose to work in a small town.

     ?。ㄊ聦嵤牵何也豢赡苁悄?,因此這只是一種假想)

      If the weather were fine now, we would have a picnic.

     ?。ㄊ聦嵤牵含F在天氣不好)

      If I had a map now, we could easily get out of the forest.

     ?。ㄊ聦嵤牵含F在沒有地圖)

      2.對過去情況的虛擬

      對過去情況的虛擬,條件句用過去完成時,主句謂語用“would/should/might/could+have+過去分詞”。

      If you had come yesterday, you would have met Tony.

     ?。ㄊ聦嵤牵耗阕蛱鞗]來)

      If it had not been for your help yesterday, I could not have caught the bus.

     ?。ㄊ聦嵤牵耗阕蛱鞄椭伊耍?/p>

      3.對將來情況的虛擬

      對將來情況的虛擬,條件句中謂語動詞可用should do, were to do或動詞的過去式三種形式,主句謂語用“would/should/might/could+動詞原形”。

      If I were to do the job, I would do it in a different way.

     ?。ㄊ聦嵤牵何液芸赡懿蝗プ鲞@項工作)

      If you should have any difficulty in getting the information, you could come directly to my office. (事實是:你可能沒有太大困難)

      If it snowed tomorrow, our plan would be postponed.

     ?。ㄊ聦嵤牵好魈旌芸赡懿粫卵?/p>


     


      4.錯綜虛擬語氣

      有時條件從句表示的動作和主句表示的動作發生的時間不一致,這類句子稱為錯綜虛擬語氣。此時主從句的形式應根據各自所表示的時間進行調整。

      If you had taken my advice then, you would not be in trouble now.

     ?。╥f條件句是對過去的虛擬,故用過去完成時,而主句是對現在的虛擬,故用would do 形式)

      If she were to leave , I would have heard about it.

     ?。╥f條件句是對將來的虛擬,用were to do形式,而主句是對過去的虛擬,故用would have done形式)

      5.含蓄虛擬語氣

      有時虛擬的條件并不是直接通過條件句來表示,而是用一些詞或短語如without, but for, otherwise等或上下文暗示來說明,這種句子叫含蓄虛擬語氣。

      Without electricity (=if there were no electricity), the world would be dark.

      But for your advice(=if it had not been for your advice), I would not have made such great progress.

      特別提示:

      虛擬條件句中有had, should, were時,可以把if去掉,然后把had, should, were提到主語前面,形成部分倒裝。

      If time were to go back/ Were time to go back, I would work harder.

      If I had worked hard/ Had I worked hard, I would have surely succeeded.

      If it should be fine tomorrow/Should it be fine tomorrow, we would go for an outing.
