1. Unlike most of the worlds volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earths surface; on the contrary, many of them lie deep in the interior of a plate.

　　跟世界上的大多數(shù)火山不同的是，它們并不總是在由構(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。

　　2. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of the plates with respect to another cannot readily be translated into motion with respect to the earths interior.

　　攜帶這些大陸板塊的相對(duì)運(yùn)動(dòng)已經(jīng)能夠被詳細(xì)地表述出來(lái)，但是這些板塊相對(duì)于另一些板塊的運(yùn)動(dòng)還不能輕易地解釋為它們相對(duì)于地球內(nèi)部的運(yùn)動(dòng)。

　　希望考生能夠認(rèn)認(rèn)真真準(zhǔn)備，爭(zhēng)取能夠順利通過(guò)考試。
