復(fù)雜的定語從句的拆分和理解 例41

例41　Unlike most of the world's volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth's surface; on the contrary, many of them lie deep in the interior of a plate.

【結(jié)構(gòu)分析】Unlike most of the world's volcanoes是個(gè)介詞短語做狀語，主謂賓是they are not always found，介詞短語at the boundaries of the great drifting plates做狀語修飾前面句子，定語從句that make up the earth's surface修飾前面的名詞，on the contrary表示轉(zhuǎn)折句，后面是簡(jiǎn)單句many of them lie deep in the interior of a plate.

【亮點(diǎn)回放】此句話的亮點(diǎn)在于兩個(gè)介詞短語很好的使用，unlike一個(gè)介詞短語在前面，一個(gè)at介詞短語在后面，at這個(gè)介詞短語加上定語從句非常奇妙，后面轉(zhuǎn)折詞匯用的不是but，而是很閃光的高分作文轉(zhuǎn)折詞匯on the contrary。

【核心詞匯】

volcanoes　多數(shù)火山

at the boundaries of　邊界上出現(xiàn)

the great drifting plates　巨大漂流板塊

make up the earth's surface　構(gòu)成地球表面

on the contrary　相反

deep in the interior of a plate　一個(gè)板塊較縱深的內(nèi)部

【參考譯文】跟世界上的大多數(shù)火山不同的是，它們（熱點(diǎn)）并不總是在由構(gòu)成地球表面巨大漂流板塊之間的邊界上出現(xiàn)；相反，它們中有許多位于一個(gè)板塊較縱深的內(nèi)部。
