appear是指根據(jù)事物的外表表象做出判斷的,但實(shí)質(zhì)上并不一定如此;seem是表示說(shuō)話人主觀上的判斷,暗含有一定的根據(jù),往往接近事實(shí)的判斷;look是根據(jù)視覺(jué)印象而得出的判斷,實(shí)質(zhì)上也可能如此。Sheisfiftybutsheappearsyoung.她五十歲了,但看起來(lái)很年輕。(其實(shí)并非如此)Sheseemsyoung.她看起來(lái)很年輕。(根據(jù)個(gè)人的主觀判斷而推斷出)Shelooksyoung.她很年輕。(從她外表可以感覺(jué)出)7.Itwasnotimmediatelyobviousthatwaterwastobefundamentaltothedevelopmentoflife.水會(huì)對(duì)于生命的發(fā)展起關(guān)鍵作用,這一點(diǎn)在當(dāng)時(shí)并不太明顯。

本句體現(xiàn)的是名詞性從句在句中作主語(yǔ)的作用,雖然是以It開頭,可是It只起到形式主語(yǔ)的作用,真正的主語(yǔ)是thatwaterwastobefundamentaltothedevelopmentoflife。用It做形式主語(yǔ)是因?yàn)閠hat引導(dǎo)的從句較長(zhǎng),如果按照正常語(yǔ)序來(lái)安排的話就顯得頭重腳輕了。如:Itisnowonderthathehaspassedtheexam.ItisquitenecessaryforustolearnEnglishwell.8.Thisproducedachainreaction,whichmadeitpossibleforlifetodevelop.Chainreaction連鎖反應(yīng)Makeitpossibleforlifetodevelop.
