alive, living, lively

alive是表语形容词，意为“活着的”，“在世的”，它既可以修饰人也可以修饰物。作定语时，应将其放在被修饰的名词后面。例如： They were alive. 他们都还活着。

living作形容词意为“活着的”，主要用作定语，常置于名词之前，有时也可置于名词之后。the living表示“活着的人”；作名词意为“生计”。例如：

Every living person has a name.每一个活着的人都有一个名字。

lively意为“生动的”，“活泼的”，“充满生气的”，用作表语或定语，可以用来修饰人或物。例如：

how long是“多久（时间）”的意思，用于对时间段提问，询问某一动作进行多长时间了。例如：
