In the past few decades, remarkable findings have been made in ethology, the study of animal social behavior. Earlier scientists had【C1】______ that nonhuman social life was almost totally instinctive or fixed by genetics. Much more careful observation has shown that【C2】______ variation occurs among the social ties of most species, showing that learning is a part of social life. That is, the statuses are not solely fixed by the genes.【C3】______ , the learning that occurs is often at an early age in a process that is called imprinting. Imprinting is clearly not instinctive, but it is not quite like the learning of humans; it is something in between the two. An illustration best【C4】______ the nature of imprinting. Once, biologists thought that ducklings followed the mother duck because of instincts. Now we know that, shortly after they hatch, ducklings fix【C5】______ any object about the size of a duck and will henceforth follow it. So ducklings may follow a basketball or a briefcase if these are【C6】______ for the mother duck at the time when imprinting occurs. Thus, social ties can be considerably【C7】______ , even ones that have a considerable base【C8】______ by genetics.
Even among the social insects something like imprinting must influence social behavior. For example, biologists once thought bees communicated with others purely【C9】______ instinct. But, in examining a "dance" that bees do to indicate the distance and direction of a pollen source, observers found that bees raised in isolation could not communicate effectively. At a higher level, the genetic base seems to be much more for an all-purpose learning rather than the more specific responses of imprinting. Chimpanzees, for instance, generally【C10】______ very good mother but Jane Goodall reports that some chimps carry the infant upside down or otherwise fail to nurture the young.
【C1】
选项
A、assumed
B、adopted
C、believed
D、surmised
答案
A
解析
assume意为“假定,设想”,多用于未证实的假定,根据题意,“早期的科学家,假定非人类动物的社会生活几乎完全是天生的,或是由遗传决定的”,所以A项为正确答案。B项adopt意为“采用,接受”;C项believe意为“相信”;D项surmise意为“猜测,推测”,相当于“guess”。如:She surmised as such.(她如此猜测。)
