新概念英语第二册中单词 work 前为什么不加定冠词

Question

Work on it had begun before my sister left. 这幢房子是在我姐姐离开前动工的。(23课)

By the end of next year, they will have finished work on the new stadium. 到明年年底他们将完成新体育场的工程。(37课)

为什么不是 the work，谢谢

Answer 1

作为动词时work是不用加the的,如:I wrok on my computer.
而作为形容词时,某些情况需要加定冠词the,这又涉及到the的用法.打个比方:
Hou interesting the work is !这里work是不可数名词,所以用the(当然,要是把work换成job的话也是用the)
联系the的用法的话,就是在上文提及或指特定事物的时候就会用到the.例如:

①He had found a piece of new work.The work was terrific.
②The work which he gived up was terrible.追问

我提问的两句中work都是名词啊，请教work作为名词时，不加the是什么原因，谢谢~

Answer 2

work后的地点状语中有the，所以work已经被限定了，不用再加冠词了。本回答被提问者采纳
