除了because还能用什么表达原因

  这种情况(贸易是主要支柱)从古至今都是如此,一部分原因是中东地区的地质环境——多为沙石和石灰岩,金属矿藏和其它有用材料很少。古代对黑曜石(一种火山岩,可以用来制作镜子和工具)的需求引发了(中东地区)与北方的亚美尼亚之间的贸易;用作切削工具的玉石从土耳其斯坦购买;而贵重的琉璃青金石是从阿富汗地区进口。

  Such anomalies are due to the relative abundance of the “isotopes” or varieties of each element.

  出现这种反常现象,主要是因为相对丰富的“同位素”或者各种元素的多样性。

  because

  Because there is no space in the periodic table between these two elements, Mendeleyev suggested that the atomic mass of indium be changed to a completely different value, where it would fill an empty space between cadmium and tin.

  但是因为在周期表中这两个元素之间没有缝隙,由此门捷列夫提出铟的原子质量变为截然不同的一个值,这样就可以将其置于镉和锡之间的空位。

  Also, because the molecular motion of a gas depends on temperature, at the low temperatures of the Jovian planets even the lightest gases are unlikely to acquire the speed needed to escape. [TPO 16-3-5]

  同时又因为气体分子运动取决于温度,所以在类木行星这样的低温环境下,即使是最轻的气体也无法达到所需要的逃逸速度。

  Pluto is not included in either category, because its great distance from Earth and its small size make this planet’s true nature a mystery. [TPO 16-3-2]

  冥王星不属于这两类中的任何一个,因为它距地球很远且体积较小,所以目前冥王星的真实形态仍然是个谜。

  because of

  The Jovian planets, because of their greater masses and thus higher surface gravities, have higher escape velocities (21-60 kilometers per second) than the terrestrial planets. [TPO 16-3-5]

  由于类木行星的质量较大并因此产生更高的表面引力,因此,类木行星的逃逸速度(21~60千米/秒)要比类地行星高得多。

  be responsible for

  Variations in the composition of the planets are largely responsible for the density differences. [TPO 16-3-4]

  行星的构成成分不同很大程度上是因为密度差异。

  account for

  Of the various hypotheses attempting to account for the late Cretaceous extinctions, the one that has attracted the most attention in recent years is the asteroid-impact hypothesis first suggested by Luis and Walter Alvarez. [TPO 15-2-5]

  各种假说都试图对白垩纪时期后期物种灭绝做出解释,近年来Luis 和Walter Alvarez最先提出的小行星撞击假说备受人们关注。

  Of the various reasons attempting to account for X, the one that has attracted the most attention is A.

  which explain why

  The disadvantage of using waterpower is that streams do not necessarily flow in places that are the most suitable for factories, which explains why so many water-powered grain and textile mills were located in undesirable places. [6-1-1]
