详析
1. A科学家把它叫做“机械螃蟹”,call意为“叫做,称呼”。
2. C由下文雄蟹必须依靠舞动自己的大螯来吸引雌蟹可知,此处的泥滩是他的“舞池”。
3. D 第二段第一句的“Male crabs attract passing females."给了我们提示,故选attract“吸引”。
4. C由下文的“if she likes the hole”可知,此处表示如果雌蟹爱上雄蟹,她就会钻进他的洞里。
5. A根据此处语境可知,雌蟹会留下来成为他的妻子。stay意为“留下”。
6. C雌蟹在两只都舞动大螯的螃蟹之间如何选择呢?between意为“在……之间”
7. B此处what引导宾语从句,并在从句中作looking for的宾语。
8. B此处由宾格them指代上文提到的the claws。
9. A雌蟹更喜欢螯较大的雄蟹。like sth. better意为“更喜欢
10. A对于一个雄蟹来说,要使自己在雌蟹面前更有吸引力,他最好选择跟软弱的朋友在一起消磨时间。
weak意为“虚 弱的,软弱的”,符合题意。
