half
1.关于half a...和a half...,参见a, an 33
2.one and a half feet和a foot and a half都可以说。
3.one and a half后面习惯接属于复数形式的名词和属于单数形式的动词。例如:One and a half apples is left on the table.
4.half of后面的名词或代词假使是单数形式,那动词也该是单数形式,名词或代词假使是复数形式,那动词也该是复数形式,如Half of it is good和Half of them are good。就理论讲,假使那个属于复数形式的名词或代词指两个东西,那动词该是单数形式。但未见过实例。在这种场合便不用half而用one了。
5.half (of) my time和half (of) the people里的of可有可无。half (of) what I have里的of用的多,不用的少。half (of) a mile, half (of) a cup等表达方式里的of通常不用。
6.half是“半”,但用作副词有两个不同的含意:“只有一半”或“竟有一半”,比较下面各句:
- The glass is half full of water. (一半)
- She spoke half aloud. (只有一半,不够)
- I am half inclined to agree. (竟有一半,相当)
- The bady is half asleep. (竟有一半,几乎)
- It would half kill him not to see you again. (竟有一半,几乎)
not half也有两个不同的含意:“不到一半”或“不止一半”。
比较下面各句:
- I don't half like it. (不到一半,一半也不到,极不)
- That's not half bad. (不到一半,一半也不到,极不)
- When I asked: 'Do you like chocolates?' he answered 'Oh, not half!'(不止一半,十分)
