英语介词的of与from

1.介系词of, from 与be made连用,皆可表示,of用以说明质料,多接wood等物质名词;from用以说明所指质料从外观上已看不出原来样子。The table is made of marble.这桌子是大理石做的。That is butter. It is made from milk.那是奶油,是用奶做的。The liquor is made from wheat.这酒是用小麦酿制的。2.Of, from可以与动词hear连用,但意义不同。Hear of 听说…。可以是听别人说起,也可以是从书籍报刊上读到过的事或了解的情况。Hear from 收到…来信,收到…消息。它不是指具体接到信件,而是指得到音信、信息。I haven't heard from you for ages.我很久没有你的消息了。Butter? I have never heard of this name.奶油?我从没听说过这个名字。
