tofail6.Withoutthisprocess,Earthcouldnotsustainlife.※本句中的withoutthisprocess是介詞短語(yǔ)，相當(dāng)于條件狀語(yǔ)從句，without引起虛擬語(yǔ)氣。Withoutthisprocess＝Iftherewerenotthisprocess，是一個(gè)與現(xiàn)在事實(shí)相反的虛擬條件句。后面的句子使用了wouldbe表示與現(xiàn)在事實(shí)相反的結(jié)果。很多情況下表示虛擬的假設(shè)并不用條件從句表示出來，而是通過上下文，利用with,butfor,or,otherwise等介詞(短語(yǔ))或連詞來表示，這就是所謂的含蓄虛擬語(yǔ)氣。①
