练习：
A A strange pattern 360 feet (110 metres) in diameter was discovered earlier this month in a wheat field in Oxfordshire，England.
B Others call them hoaxes.
C No one knew how or by whom they were made.
D The design’s discovery immediately generated a new tide of public interest in this mysterious phenomenon.
E Farmers often make crop circles for fun.
F But rather than discovering the truth，people saw increasingly complicated circles appear worldwide.
答案与题解：
1. B 选项B是：Others call them hoaxes.其他人把他们叫做骗局。前面一句话是：Many people believe that they are made by aliens.许多人相信它们是外星人搞的。many和others有一定的关联性。因此选B。
2. A 紧随其后的句子是：It’s believed to be the world’s first three-dimensional crop circle.它被认为是世界上第一个三维的作物圈。代词在这里是一个照应词，它从前面的先行词获得它的指称意义。这个先行词是哪个呢?看一看提供的几个选项，只有Astrange pattern 360 feet(110 metres)in diameter是合适的。因此A是正确的。
3. D 上文是：The giant crop circle gives an impression of looking down on Skyscrapers fromabove.这个巨大的作物圈给人以一种从上向下看摩天大楼的印象。这是在讲作物圈的造型或设计。因此填入D是最合适的。D说的是：The design’s discovery immediately generated a new tide of public interest in this mysterious phenomenon.这一设计的发现即刻生成了一个大家关注这一神秘现象的新浪潮。
4. C 上文是：They were huge(at least tens of metres in diameters)and popped up over-night.它们巨大(直径至少有几十米)并且是一夜之间突然冒出来的。这个句子实际上已经蕴涵着不知道是谁弄的以及是怎么制造出来的。因此C是合适的。C是这么说的：No one knew how or by whom they were made.没有人知道它们是如何制造出来的，也不知道是谁弄的。
5. F 上文是：Various scientific and pseudo-scientific explanations were put forward to explain the phenomenon.Some hold that they were left by alien spaceships.Others say that they are simply an elaborate prank.各种各样的科学的和伪科学解释都提了出来解释这一现象。有的说是外星人的太空飞船留下的。有的说它们只是些精美的骗局。从主题的发展来说，还可以继续争论下去，当然也可以把争论搁置起来。选项F表达的是搁置争论。从主题发展来说也是连贯的。
