在英語(yǔ)學(xué)習(xí)中,虛擬語(yǔ)氣通常是重點(diǎn)加難點(diǎn),考試從來(lái)不會(huì)少出,但又往往弄得同學(xué)們焦頭爛額,丟分不斷,滬江小編今天就來(lái)和大家一起學(xué)習(xí)一下什么是虛擬語(yǔ)氣。

英語(yǔ)的動(dòng)詞有三種語(yǔ)氣形式,即陳述語(yǔ)氣、祈使語(yǔ)氣和虛擬語(yǔ)氣,陳述語(yǔ)氣用來(lái)說(shuō)明事實(shí)或就事實(shí)提出詢(xún)問(wèn),祈使語(yǔ)氣用于表示請(qǐng)求、命令、建議或警告等,而虛擬語(yǔ)氣則是謂語(yǔ)動(dòng)詞的一種特殊形式,用來(lái)表達(dá)假設(shè)、猜測(cè)、可能或空想等虛擬情況,也可以表示主觀愿望或表達(dá)某種強(qiáng)烈的感情,通常出現(xiàn)在各類(lèi)從句中。
