用完形填空【语篇解读】舐犊之情，济危扶弱，勇敢和关爱，这些品质不只人类社会才有，自然界动物之间也是如此。21.B通读全文并结合下文三个实例可看出,面对某些情境，动物和人类并没有什么不同。22.Asituation＂情况，形势＂。文章最后一句中的＂ifacertainsituationoremergencypresentsitself＂是呼应.23。Dtakecareof＂照顾＂。此处表示一只母狮子照顾一只羚羊孤崽。24.C出于本性，这只母狮子远离了自己的族群,因为她知道其他狮子会轻易地杀死她这只不寻常的幼崽.nature＂本性＂。25.B参见上题解析。26。C根据下文的＂thelionesswasunabletomakeakill＂和＂shedidn'thaveanymilk＂可推知,此处表示他
