Question

through和throughout有什么区别?
hard work right through the summer 持续了整个夏天的辛苦工作
trips for older people all through the year
A cup of coffee is not enough to keep me awake all throughout the day.一杯咖啡不足以让我一整天都保持清醒.
Many countries in Asia,for example China and Thailand,have a lot of tourists throughout the year.很多亚洲国家,比如中国、泰国,全年都会接待大量游客.
当它们两个表示时间的时候不是差不多一个意思吗,怎么看啊

Answer 1

这真的是一个很好的问题.
这两个在例句中都是介词用法.后者比前者多了个out.
through是一个动态介词,常与表示动态的位移动词或（名词）连用,如：walk through the forest.
在时间的数轴上,through表示从一段时间的起点至终点的这个过程.
多了个out的介词throughout ,重点在这个out上.
用汉语来翻译思考,all through the year 和 throughout the year 相当于全年和一年到头的区别吧.
感觉最后一个例句中的have不是位移动词,所以不能用though,
第三个例句,可以用through代替throughout,只是语气不同.
前两个例句不宜用throughout
这是我个人的判断.
最好还是去查一查词典,找出更多的例句.
