head 用作名词，意思是“首领”、“领导”、“头儿”，应根据相应的职务进行汉译。此时 head 前一般不用不定冠词，而用定冠词或不用冠词。例如：The original founder is still head of the organization. 原先的创立者现仍然是这个组织的领导。/ He is (the) head of the English Department. 他是英语系主任。/ He was the first non-Christian to be head of Chad. 他是第一位非基督教徒的乍得国家元首。/ Bill was appointed head of the Election committee when the government crisis was over. 政府危机结束后，比尔被任命为选举委员会主席。 (摘自《薄冰英语惯用法词典》)
