3、The Theory ofcontinental drift has had a long and turbulent history since it was first proposed by Alfred Wagener in 1910.(大陆漂移理论自阿尔弗雷德·魏格纳在1910年首先提出之后,经历了一段漫长和混乱的历史。)
4、Seventy million years ago, India lay south of the Equator. It was headed north, though, and by continental-drift standards, it was moving fast.(七千万年前,印度大陆位于赤道之南,按照大陆漂移学说的标准,印度大陆头朝北快速移动。)
5、Why this elaborate analogy with plate tectonics andcontinental drift?(为什么要煞费苦心地拿板块学说和大陆漂移来进行类比?)
6、Massive segments or plates of the crust move over the mantle in the process ofcontinental drift.(大陆漂移雕塑了地壳的外观,使现在大陆形成。)
7、Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics andcontinental drift, mountain building, and earthquakes.(地球内部因放射而产生的热量为板块运动、大陆漂移、造山运动和地震提供了能量。)
8、A few writers have suggested that perhapscontinental drift causes polar wandering.(一些作家已经提议也许大陆漂移引起两极漫游。)
9、The scientists didn't accept the hypothesis ofcontinental drift until almost identical fossils of animals were found both on Africa and South America.(直到在非洲和南美洲发现了几乎完全同类的动物化石,科学家们才接受了大陆漂移假说。)
10、Stephen Jay Gould, for example, argues thatcontinental 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·古尔德认为,大陆漂移理论之所以被否决,是因为它没有解释大陆是如何穿过明显很坚固的海底的。)
11、In 1912, Alfred Wegener proposed, in a widely debated theory that came to be calledcontinental drift, that Earth's continents were mobile.(1912年,阿尔弗雷德·魏格纳在一个被称为“大陆漂移”的理论中提出,地球上的大陆是可移动的。) [hao86.com好工具]
