问题    The bat is a marvel of evolutionary adaptation. Most of them roost during the day, and are active at night or twilight for they can avoid objects in the dark. I have seen this phenomenon at work. In my youth I used to explore old mining shafts in the Randsburg district. Sometimes my intrusion disturbed clans of bats that were hanging upside down in the dark caves.
   They would fly about to evident panic, but the panic was mine, not theirs. Some flew crazily out into the daylight but some merely returned to their perches. None ever touched me, much to my relief.
   They may exist but I have never seen a stuffed nylon bat. To children, bats may not be as lovable as koala bears. Perhaps manufacturers do not regard them as marketable. It is not so much their hideous faces and winged bodies that have caused us to get rid of bats, but rather the ancient myths in which dead humans, such as Count Dracula, leave their graves at night in the form of bats to suck blood from human victims, especially fragile young woman. As we know from some movies these vampires must return to their graves before daylight. Endangered young women can frustrate vampire by sleeping with a string of garlic around their necks.
   There are actually three species of bloodsucking bats. They are called vampire bats after the ancient legends, and their tactics are indeed frightful. Like Count Dracula, they feed at night. They make a small cut in their sleeping victim with sharp incisor teeth, usually not even awakening their prey. Then they suck the blood that sustains them.
   Should that discourage children from wanting them as pets?
   As Mitchell notes from the New Yorker ad, bats are clean and intelligent. Most of them are insect-eaters, and they serve nature by destroying crop-damaging insects. They also pollinate (传授花粉)  flowers and spreading seed.
   Bat Conservation International claims that without bats a host of insects/pests would multiply unchecked and many of our planet’s most valuable plants would go unpollinated.
   It is clear that the bat is our friend, and that, despite its appearance, it is here to serve humanity.
   I’d be the first to buy a stuffed nylon bat. Children’s hearts are big, and bats need love, too.
The toy companies are rarely interested in making a toy bat probably because ______.
选项 A、bats destroy crop-damaging insects
B、bats are the marvel of evolution adaptation
C、bats suck the blood of dying people
D、bats inspire disgust based on some traditional beliefs
答案D
解析 由第四段得知，生产商认为蝙蝠玩具不大会有市场，这主要倒不是因为蝙蝠吓人的脸和长翼的身躯，而是由于一些恐怖传说，比如，传说德拉库拉伯爵晚上就从坟墓中出来，化身成蝙蝠吸食人血，尤其是娇弱(fragile)的妇人的血。
