There are exceptions to the rule of male insects being smaller than the females, and some of these exceptions are intelligible. Size and strength would be an advantage to the males which fight for the possession of the females, and in these cases, as with the stag-beetle (Lucanus), the males are larger than the females. There are, however, other beetles which are not known to fight together, of which the males exceed the females in size, and the meaning of this fact is not known, but in some of these cases, as with the huge Dynastes and Megasoma, we can at least see that there would be no necessity for the males to be smaller than the females, in order to be matured before them, for these beetles are not short-lived, and there would be ample time for the pairing of the sexes.
The paragraph preceding this one probably ______.
选项
A、discusses a generalization about the size of animals
B、develops the idea that male insects do not live long after maturity
C、discusses male and female beetles
D、emphasizes that beetles are belligerent animals
答案
A
解析
该自然段之前的那个自然段很可能讨论动物大小的一般规律。可以这样推理:作者在本段第一句说,就雄性昆虫比雌性昆虫要小这一规律而言,存在一些例外。前面的自然段肯定在讨论这一规律。
