例154　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.

【结构分析】句子前半句是个让步状语从句Although perhaps only 1 percent of the life that has started somewhere will develop into highly complex and intelligent patterns，后面是so...that...引导的倒装句，so后面倒装，that后面不倒装，so vast是个表语，被倒装到了前面，后面是系动词is，后面是真正的主语the number of planets, that后面是后半句，用的是正常语序，intelligent life is bound to be a natural part of the universe。

【亮点回放】此句话的亮点so...that...引导的倒装句，so后面倒装，that后面不倒装，比如正常语序是she is so charming that everybody loves her.倒装为So charming is she that everybody loves her。

【核心词汇】

highly complex　高度复杂的

intelligent　智能的

vast　大量的

intelligent life　智能生命

be bound to　必然

【参考译文】虽然只有在某个地方起源的生物中只有百分之一能变成高度复杂和智能的生物，但是宇宙的行星如此众多，以致于智能生命必然是宇宙中正常的一部分。
