VOA慢速英语:Taking Action Against Child Labor

still的用法：

still强调过去发生的事情及存在的状况目前还在延续。在现在完成时的否定句中，still表示吃惊或不耐烦的语气；但在现在进行时中，still

只表示动作正在持续，不带有感情色彩。例如：

My neighbour hit my car last week and he still hasn't apologised.
我的邻居上周撞了我的车，可他到现在还没有道歉呢。
 
He's still living with his mother.
他仍与母亲住在一起。

still还可以用来修饰比较级，相当于even，可译为“更”、“还要”、“甚”。例句：

(1) We must study still harder. 我们必须更加努力地学习。

(2) It was cold yesterday, but today it is still colder. 昨天天气很冷，可今天却更冷。

(3) Her sister is still taller. 她妹妹个子还要高。

(4) They came still earlier. 他们来得更早。
