分析句子：They are good-natured,cooperative creatures,and they share their food readily.
They look cute.They are good-natured,cooperative creatures,and they share their food readily.第一句是什么结构.第二句they share their food readily 中readily做什么成分
答
第一句They look cute是主系表结构,look 为半系动词.第二句中,good-natured,cooperative是形容词,后面修饰creatures,所以是主谓宾结构.readily修饰动词share,在句中作状语.
