复杂的形式主语和形式宾语的拆分和理解 例202

例202　From what is stated above, it is learned that the sun's heat can pass through the empty space between the sun and the atmosphere that surrounds the earth, and that most of the heat is dispersed through the atmosphere and lost but what extent it is lost has not been found out.

【结构分析】句子开头加了个介词短语From what is stated above做状语，修饰整个句子，句子的主干是it is learned...，后面是两个并列的主语从句，第一个主语从句是that the sun's heat can pass through the empty space between the sun and the atmosphere...，后面加上定语从句that surrounds the earth，修饰前面的名词the atmosphere，第二个主语从句是that most of the heat is dispersed through the atmosphere and lost...，后面加上转折句but what extent it is lost has not been found out。

【亮点回放】此句话的亮点在于考的是It is adj that...and that...，这种结构让句子充满生命力，其中第一个that里面有介词短语，还有定语从句，难度很大，第二个that里面有转折句和主语从句，难度也不小，很棒。

【核心词汇】

pass through　穿越

empty space　空白区域

the atmosphere that surrounds the earth　大气层

disperse　消耗

what extent it is lost　能量消耗的程度

【参考译文】正如以上而言，据说太阳的热量能够穿越太阳和大气层之间的空白区域，而且其大部分热量在穿越大气层的时候已经被消耗一部分，但是到底消耗多少说不清楚。
