Question

Once the plan was approved,the department ____ on the project.
a) began work
b) are worked
c) have worked
d) had been working
为什麼答案是 a begin 后面不是接不定式或动名词吗?因为这点,我才选

Answer 1

答案只能是A!
原文的意思是：一旦计划通过,部门职能就是执行计划!
首先我们确定该句的整体都是过去式,直接排除BC!
如果用D的话,原文的意思就解释不通了,刚获准通过,怎么就可以说是一直在执行呢?
你的问题是WORK应该用WORKING?
其实WORK在这里是名词,BEGAN WORK ON THE.
就是开始做什么工作.
不知道你明白了没?
