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.
Study on animals from ants to apes has found that different【B3】______have different personalities. Some are timid, others【B4】______. 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. But it’s hard to run evolutionary【B8】______on these personalities in anything longer lived than a fruit fly. So evolutionary biologist Vincent from Canada came up with an idea about dogs. "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.

解析
语义推断题。此空所在宾语从句的谓语动词为evolve,故空格处应填入复数名词。前文提到Personality influences life span,后文则表明新的研究可能有助于解释这一现象。本文重点讨论动物的性格是如何影响寿命的,可推测这一现象应该与动物的性格有关,所填名词应该与前面的Personality是同义词。结合录音,不难填入characters。
