Module2EnvironmentalproblemsUnit3Theenvironment第2課時(shí)Reading·下冊(cè)·要點(diǎn)精講Withoutit,theEarthwouldbethesameastheMoon—coldandlifeless.沒(méi)有它，地球?qū)?huì)像月球一樣冷冰冰的，毫無(wú)生命跡象。本句是虛擬語(yǔ)氣。虛擬語(yǔ)氣是說(shuō)話者用來(lái)表示假設(shè)或難以實(shí)現(xiàn)的情況，而非客觀存在的事實(shí)。它所陳述的是一個(gè)條件，不一定是事實(shí)，甚至可能與事實(shí)完全相反。使用虛擬語(yǔ)氣時(shí)，若表示與現(xiàn)在事實(shí)相反，則從句要用一般過(guò)去時(shí)(be用were而不用was)，主句用would/should/could/might+動(dòng)詞原形。句中的without…相當(dāng)于ifthereweren't…。如：Iftherewerenoairorwater，therewouldbenolivingthingsonEarth.如果沒(méi)有空氣或者水，地球上就不會(huì)有生物。(事實(shí):地球上既有空氣也有水)WithouttheSun,nothingwouldgrow.沒(méi)有太陽(yáng)，什么東西都不會(huì)生長(zhǎng)。.(
