adj.形容词
half用作形容词的意思是“一半的”,表示“半个某物”时,英式英语多用half a…; 美式英语多用a half…。 half也可作“…点钟以后半小时”解。 half可直接修饰名词,但不可直接修饰代词。
n.名词
half用作名词的基本意思是“半”,指把一个整体分成不一定平等的两部分。引申可指“二分之一”,体育比赛的“半场”,公共汽车或火车上的“半票”,在口语中还可指啤酒等液体的“半品脱”。 half of后接名词或代词作主语时,动词的数应根据名词或代词而定。如果该名词或代词是复数形式,则其后的谓语动词用复数形式; 反之,则用单数形式。 half常接介词of,意为“…的一半”, of后可接除尺寸、数量以外的名词或代词。 half前一般不用定冠词,但在有形容词或相当于形容词的词确切地表示出所谈论的那一件事时,才可加定冠词。
adv.副词
half用作副词时的意思是“半”“部分地”,还可指同等程度的“一半…,一半…”。有时仅用来加强语气,无词意。
