　　水会对于生命的发展起关键作用，这一点在当时并不明显。

　　本句是名词性从句在句中作主语，虽然是以it开头，但是it只起到形式主语的作用，真正的主语是that water was to be fundamental to the development of life。用it作形式主语是因为that引导的从句较长，如果按照正常语序来安排的话就显得头重脚轻了。类似的还有：

　　It is no wonder that he has passed the exam.

　　他顺利通过了考试 ，这一点不奇怪。

　　2．Others, called amphibians, were able to live on land as well as in the water.

　　Some students are reading books and others(＝other students) are writing their compositions.

　　3．Why they suddenly disappeared still remains at mystery.

　　他们为什么会突然灭绝至今还是个谜。

　　●用法拓展

　　(1)本句中why they suddenly disappeared是名词性从句在句中作主语，引导词是关系副词why，在从句中作原因状语。能够引导名词性从句的关系副词还有：when，where，how等，在从句中都是作状语。如：

　　Please remind me when he is going.I will see him off.

　　请提醒我他什么时候出发，我去给他送行。
