 　　Seahorse Fathers

　　It’s true that male seahorses never play catch with their children or help them with their homework. But they do outdo human dads on one count. (1)The trait is unique in these strange and fascinating fish that inhabit tropical and temperate coastal waters worldwide. Seahorses, which range from less than an inch to a foot in length, have evolved a series of unusual adaptations. (2)The male seahorse has a pouch(育儿袋)on its stomach in which to carry babies as many as 2000 at a time. A pregnancy lasts from 10 to 25 days depending on the species. (3) Eventually they engage in a true courtship dance, which can last as long as eight hours. It ends with the female depositing her eggs in the male's pouch.

　　The eggs hatch in the pouch. (4) When the tiny seahorses are ready to be born the male undergoes muscular contractions to expel the young known as “fly” from the pouch.

　　While seahorse dads go the extra mile to give birth the parents do not provide their tiny offspring with any care or protection after they are born. Infant seahorses are susceptible to death from predators(食肉动物)and being swept into ocean currents where they drift away from feeding grounds rich in microscopic organism. (5)

　　A.The father cares for the young as they grow regulating the water salinity(盐分) in the pouch to prepare them for life in the sea.

　　B. They are such an unusual looking fish that people sometimes don't realize they're real fish.

　　C. Male seahorses undergo pregnancy and give birth to their sons and daughters.

　　D. In spite of all our scientific research, we are only just beginning to understand how the seahorse fathers bear children.

　　E. The reproductive process begins when a male and a female seahorse do daily predawn dances their tails swimming together.

　　F. Fewer than five infant seahorses in every 1000 survive to adulthood which helps explain why the litters are so large.

　　正确答案:CBEAF

　　解析:1.C 上一句话说，海马爸爸确实胜过人类的爸爸。那么接下来应该说明具体在哪方面胜过人类的爸爸，所以C“雄海马承担了怀孕直至到儿女出生这项任务”是正确的选项。

　　2.B 上一句话说，它们已经进化出一系列不同寻常的适应性特征。所以本句应该继续进行在特征上的表述，即B“它们是外貌如此奇特的鱼类，以至于人们往往没有意识到它们是鱼类。”是正确的选项。

　　3.E 这一句说的是“繁殖过程开始时，雌雄海马像往常一样在黎明前跳舞，将尾巴交织在一起游泳。”下一句正好继续说明它们接下来做什么，“最后，它们开始了真正的求婚舞蹈，这一过程可持续长达8个小时”所以E是正确的选项。

　　4.A 前一句说的是受精卵在育儿袋中孵化。接下来应该讲的是孵化过程中的事情，所以A“父亲照料小海马的生长发育，为了让小海马适应海水中的生活而调节育儿袋中水的盐分。”是正确的选项。

　　5.F 这一段主要讲的是小海马出生之后的事情，即，海马父母对于孩子疏于照顾而导致好多小海马早年夭折或者失踪。从海马爸爸生孩子和这些小海马的存活率之间的联系来看，最后一句应该对小海马的存活数量加以具体说明并做出总结，点明主题，即“1000只小海马中只有不到5只能够长大成熟，这也可以解释为什么海马一次繁殖的数目这么大。”
