问题     In the cause of equal rights, feminists(女权主义者)have had much to complain about. But one striking piece of inequality has been【C1】______: lifespan. In this area, women have the【C2】______hand. All round the world, they live longer than men. Why they should do so is not【C3】______obvious. But the same is true in many other【C4】______From lions to antelope and from sea lions to deer, males, for some reason, simply can’t go the distance.
    One theory is that males must【C5】______for female attention. Females are not subject to such pressure. If this theory is correct, the effect will be especially【C6】______in those varieties where males rival for the attention of lots of females. Conversely, it will be reduced or absent where they do not.

Most scholars of ageing agree that an animal’s【C7】______lifespan is set by how long it can reasonably expect to escape predation(捕食), disease, accident and damaging【C8】______by others of its kind. If it will be killed quickly anyway, there is not much reason for evolution to divert scarce resources into keeping the machine in excellent condition. Those resources should, instead, be【C9】______to reproduction. And the more【C10】______the outside world is, the shorter the lifespan should be.
A)overlooked F)threatening K)spontaneous
B)upper G)undoubtedly L)devoted
C)aggression H)species M)combine
D)immediately I)evident N)upright
E)clumsy J)compete O)maximum
【C3】
选项
答案D
解析 副词辨析题。空格处位于be动词和表语obvious之间，因此需填副词修饰obvious。该句意为“女性为什么能比男性寿命长，原因尚不能——确定。”由此推断，immediately“立即，马上”符合题意。
