By 1946, however, the battle over continental drift was in full swing.(然而，到1946年，對(duì)大陸漂移說(shuō)的戰(zhàn)斗進(jìn)行得如火如荼。)

Wegener proposed the continental drift theory.(魏格納提出了大陸漂移說(shuō))

The Theory of Continental Drift has had a long and turbulent history since it was first proposed by Alfred Wagener in 1910.(大陸漂移理論自阿爾弗雷德·魏格納在1910年首先提出之后，經(jīng)歷了一段漫長(zhǎng)和混亂的歷史。)

Seventy million years ago, India lay south of the Equator. It was headed north, though, and by continental-drift standards, it was moving fast.(七千萬(wàn)年前，印度大陸位于赤道之南，按照大陸漂移學(xué)說(shuō)的標(biāo)準(zhǔn)，印度大陸頭朝北快速移動(dòng)。)

Why this elaborate analogy with plate tectonics and continental drift?(為什么要煞費(fèi)苦心地拿板塊學(xué)說(shuō)和大陸漂移來(lái)進(jìn)行類比？)

Massive segments or plates of the crust move over the mantle in the process of continental drift.(大陸漂移雕塑了地殼的外觀，使現(xiàn)在大陸形成。)

Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes.(地球內(nèi)部因放射而產(chǎn)生的熱量為板塊運(yùn)動(dòng)、大陸漂移、造山運(yùn)動(dòng)和地震提供了能量。)

A few writers have suggested that perhaps continental drift causes polar wandering.(一些作家已經(jīng)提議也許大陸漂移引起兩極漫游。)

The scientists didn't accept the hypothesis of continental drift until almost identical fossils of animals were found both on Africa and South America.(直到在非洲和南美洲發(fā)現(xiàn)了幾乎完全同類的動(dòng)物化石，科學(xué)家們才接受了大陸漂移假說(shuō)。)

Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor.(例如，斯蒂芬·杰伊·古爾德認(rèn)為，大陸漂移理論之所以被否決，是因?yàn)樗鼪](méi)有解釋大陸是如何穿過(guò)明顯很堅(jiān)固的海底的。)
