    单词用法

    语法解说
    ①“half+名词”或“half of+名词”作主语时,谓语动词的单、复数形式由所接名词的单、复数形式来决定,名词是中心词.例如Half(of)the oranges are bad.一半的桔子坏了Half(of)the car was damaged.那辆车有一半被损坏了=②“……个半……”可表达为“数词+名词+and a half”或“数词+and a half+名词(复数)”.例如三个半月three months and a half/three and a half months
    单词用法
    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。
    重要短语
    and a half了不起的;而且比这多得多
    in half分成两半
    one half一半
