Small dogs generally live longer than big dogs so that small Yorkshire terrier (猎狐狗) next door could be around for a long time. But body size isn’t the only factor that【B1】______how long dogs survive. Personality influences life span, too, according to a new study that might help explain how animal【B2】______evolve.

Biologists have proposed that temperaments (性情) evolved along with life history.【B5】______, violent animals use a lot of energy fast in【B6】______short lives, the thinking goes, whereas calmer animals last longer, saving themselves to【B7】______ later in life.

"All these breed differences reflect an experiment on artificial selection," says Vincent.【B9】______—the ability to chase foxes into holes, or herd sheep, or sit attractively on a sofa.
But evolutionary physiologist Joseph Williams of Ohio State University in Columbus isn’t convinced that 【B10】______. "For me, it still remains to be seen.

选项
答案
researches
解析
语义推断题。此空被形容词evolutionary修饰,所以应填入名词。联系上下文可知,有关这些动物“性格”进化的研究很难操作,由此推测此处应该是说明操作或研究的形式。结合录音,不难填人researches。
