中心词
在句a中,表层结构中的visiting是深层结构中分词短语的中心词(head noun),作主语。但因visiting仍保留了及物动词可带宾语的特点,与relatives构成了动宾关系。

A head is the cephalic part of an organism, which usually comprises the eyes, ears, nose and mouth, each of which aid in various sensory functions, such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nerve tissues concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the interior region; these collectively form the head.
