sound可以用作名词、动词和形容词。下面分述其用法要点及考点。
1.sound用作名词,指“声音,响声”。比如:
There was a strange inhuman sound.有一种不像人发出的奇怪声音。Sound travels more slowly than light.声比光传播得慢。
2.sound用作动词时,可以是及物动词或不及物动词。
做及物动词时,指“使发声”。比如:
Would you please not sound your trumpet so early in the morning?请您早晨不要这么早吹喇叭好吗?
用做不及物动词时表示“响,发声”,比如:When we were about to sleep, the trumpet sounded.我们正要入睡时,喇叭声响起来了。
sound用做不及物动词时的另外一个意思是“听起来”。比如:
She sounded a bit worried.她听起来有点焦虑不安。Tom sounds like a child.汤姆听起来像个孩子。They heard what sounded like a huge explosion.他们听见了一种像是巨大爆炸的声音。
3.sound 用作形容词,一般有下面两个意思。
sound指“健全的,完好的”。比如:
When we bought the house, it was structurally sound.当我们买下这房子时,其结构完好无损。A sound mind lives in a sound body.有健康的体魄,才有健全的心智。
sound的第二个意思是“正当的,合理的”。比如:
He gave me some very sound advice.他给了我一些非常合理的忠告。
4.考点
1)sound后面常接形容词而不是副词,它的用法和look、smell、seem等动词相似。比如:Do I sound envious? I pity them, actually.我听起来像是羡慕吗?其实,我可怜他们。
2)sound like 结构,表示“听起来像,看起来是”。比如:
He didn't sound like his usual happy self.他听起来不像平常那个乐天派了。That sounds like a good idea.这看起来是个好主意。
3)常考sound、noise及voice的区别。sound统指声音。noise的意思“噪音”,指可以听到的任何令人不快的声音。voice指人说话或唱歌的声音,有时也可以指鸟鸣,但一般不指动物的叫声。
5.要点
sound和healthy均作形容词,可以指“健全的”。它们的区别是sound中性词,也就是说指没有疾病或缺陷,和形容词well表示的意思基本相同。healthy常指人体或心智状态正常或者良好,含有褒义。
