题目分析:
本题的意思是:自从人类有能力发生卫星,在地球的轨道周边就开始有越来越多的垃圾,经常是来自于某些有意丢掉的油箱什么的。
选项分析:
A选项:语法有误。最后一个词because是连词,其身后必须连接一个句子,不能是一个名词短语。
B选项:Correct. 本选项在语法和逻辑上均是正确的。
C选项:often resulting from the intentional discarding of lens caps, packing material, fuel tanks, and payload covers是一个现在分词短语。在语法上,句末出现的现在分词短语通常都是伴随状语。因此,result的主语只能是其所修饰的句子的主语orbits。在逻辑上,“轨道”不能是“有意丢掉油箱等废物”的结果。
D选项:there be句型的核心词是“有”。即,本句主干的意思是:
这里有很多垃圾。
在逻辑上,“有意丢掉油箱”结果应该是“地球轨道周围变得越来越脏”,而不是“这里有很多垃圾”。(只有地球周边会变得垃圾越来越多,因为故意丢弃的东西都是地球人弄出的东西)
E选项:本选项错误同(D)。
A because of B 表示B led to A, 可以理解为先发生了b,之后发生了a,这两件事是独立的,是不同的事情
可以说:more littering has occurred because of the lax enforcement of laws against littering.
不能说: more littering has occurred because people have been throwing bottles along the side of the road。人们在路边扔瓶子和垃圾越来越多是一件事情。
D,
这里有越来越多的轨道附近的垃圾和这些国际废弃物,比如……也是一件事情,不能用because of修饰
