. Although perhaps only 1 percent of the life that has started somewhere will develop into highly complex and intelligent patterns，so vast is the number of planets that intelligent life is bound to be a natural part of the universe.

　　結(jié)構(gòu)分析:句子的框架是Although…，so vast is the number of planets that…。主句為so…that…結(jié)構(gòu)引導(dǎo)的結(jié)果狀語(yǔ)從句，因強(qiáng)調(diào)vast,so vast放在句首進(jìn)行倒裝,正常語(yǔ)序?yàn)閠he number of planets is so vast that…。although引導(dǎo)讓步狀語(yǔ)從句。此從句中套嵌一個(gè)關(guān)系代詞that引導(dǎo)的定語(yǔ)從句修飾life。be bound to意為“一定,必定”。

　　譯文: 雖然在某處已經(jīng)開始的生命中，可能僅有百分之一會(huì)發(fā)展成高度復(fù)雜、有智慧的形式，但是行星的數(shù)目如此之多,以致于有智慧的生命,一定是宇宙的一個(gè)天然組成部分。
