復雜的形式主語和形式賓語的拆分和理解 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.

【結構分析】句子開頭加了個介詞短語From what is stated above做狀語，修飾整個句子，句子的主干是it is learned...，后面是兩個并列的主語從句，第一個主語從句是that the sun's heat can pass through the empty space between the sun and the atmosphere...，后面加上定語從句that surrounds the earth，修飾前面的名詞the atmosphere，第二個主語從句是that most of the heat is dispersed through the atmosphere and lost...，后面加上轉折句but what extent it is lost has not been found out。

【亮點回放】此句話的亮點在于考的是It is adj that...and that...，這種結構讓句子充滿生命力，其中第一個that里面有介詞短語，還有定語從句，難度很大，第二個that里面有轉折句和主語從句，難度也不小，很棒。

【核心詞匯】

pass through　穿越

empty space　空白區(qū)域

the atmosphere that surrounds the earth　大氣層

disperse　消耗

what extent it is lost　能量消耗的程度

【參考譯文】正如以上而言，據說太陽的熱量能夠穿越太陽和大氣層之間的空白區(qū)域，而且其大部分熱量在穿越大氣層的時候已經被消耗一部分，但是到底消耗多少說不清楚。
