with , by 的用法问题
1. by表方式:
(1)表示以一般的方法或方式.如:
No one in those days could live by writing poems.
(2)表示传达、传递的方式或煤介.如:
How did you send the letter, by airmail or by ordinary mail?
(3)表示用交通工具、通讯工具后接名词单数,不加冠词.如:
He came by train, but his wife came by bus.
注意下面两句的区别:
Did you come by train?
Did you come in his car / on my bike?
“by +抽象名词”构成的词组有:by accident / by chance / by diligence / by effort / by force / by heart / by luck / by mistake / by hard work.
2. through表示“以;通过;经由”.如:
He succeeded through hard work.
3. with表示方式
(1)表示行为方式,意为“以;带着;用”.如:
We are well provided with food and clothing.
(2)表示使用具体的工具或手段.如:
He writes with a pen.
注意:在表示手段时,by, through, with有时也可换用,但with的意思更明确.如:
Through / By / With his efforts he succeeded in making so many useful inventions.
