分析:該句的骨干結(jié)構(gòu)為"It is realized that ...",it為形式主語,that引導(dǎo)主語從句以及并列的it is even possible to ...結(jié)構(gòu),其中,不定式作主語,the time ...是"expectation of life"的同位語,進(jìn)一步解釋其含義,而time后面的句子是它的定語從句。五個(gè)謂語結(jié)構(gòu)表達(dá)了四個(gè)層次的意義:A. 可是現(xiàn)在人們意識(shí)到;B. 其中有些礦物質(zhì)的蘊(yùn)藏量是有限的;C. 人們甚至還可以比較合理地估計(jì)出這些礦物質(zhì)"可望存在多少年";D. 將這些已知礦源和儲(chǔ)量將消耗殆盡的時(shí)間。
