问题 What part does the female sea horse play in having babies?
What can be learned from the passage about giving birth to baby sea horses?

选项 A、It is dangerous for the female.
B、It happens once a year.
C、It is hard work for the male.
D、It occurs in the deep sea.

答案C

解析 本题可用排除法来做。A、B和D三项文中均未提到。本文通篇在讲述雄性海马保护卵子及孵化幼仔的辛苦过程。尤其是第五段指出有时候要用两天时间才能孵化出所有幼仔,可见雄性海马非常辛苦。
