shapewouldlastornot.地球开始变得激烈动荡，不知道这个固体形状是否会继续存在下去。这是一个主从复合句，so……that……“如此……以至于……”，that引导结果状语从句，在结果状语从句it中作形式主语,真正的主语是whether……ornot这个主语从句。Itisnotclear+从句意为“不知道……；不清楚……”n.固体

solid,liquid,gas

adj.固体的；实心的,无空隙的；结实的，坚固的

It是形式主语,真正的主语是thatwaterwastobefundamentaltothedevelopmentoflife.所以that引导的是一个主语从句。用It做形式主语是因为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.如:

Itisnowonderthathehaspassedtheexam.fundamentaladj.根本的；基本的；基础的Readingisafundamentalskillforastudent.拓展：befundamentalto是……的基础fundamentallyadv.根本上；完全地Freshairisfundamentaltogoodhealth.Thetwowaysarefundamentallydifferent.8.Whatmanyscientistsbelieveisthatthecontinuedpresenceofwaterallowedtheearthtodissolveharmfulgasesandacidsintotheoceansandseas.allowvt.允许、许可、容许allow+n./pron./doingallowsb.todobeallowedtodobeharmfulto
