It is fine sand.这是细砂。

Are you feeling better now? (句末省略了than before ) 你现在感觉好些了吗?

Who is the youngest, your father, your mother, or your aunt? 在你爸、妈和姑姑三人中,谁最年轻?
值得注意的是,当句中出现三者或三者以上的比较对象时,也可以把其中的一个作为比较对象的一方,而其它的所有的比较对象作为另一方,用比较级形式进行比较。例如:
Tom is taller than Kate and Mary.(= Tom is the tallest of the three.) 汤姆是三个人中个子最高的。
