试题解析
录音中提到“Although elephants can live for up to 60-70 years, with the threat from ivory poaching few mature elephants with good ivory reach this age.”(尽管大象可以生活长达60-70年,但是由于象牙偷猎活动的威胁有良好象牙的成年大象很少达到这一年龄),所以C项正确,但是由此不能推断出通常大象都在60-70岁时死去,故A项错误。根据录音可知,雄性和雌性非洲象都有象牙,但是只有雄性的亚洲象有象牙,由此可知,雌性亚洲象没有象牙,所以B项正确。根据“Elephants are also being killed for their meat”可知,D项也正确。
