英语语法问题 All the tasks______ahead of time,they decided to go on holiday for a week.
A.having been fulfilled B.had been fulfilled 这个题选A,原因是A不是一个句子,我的疑问是:fulfilled不是动词吗?为什么All the tasks having been fulfilled ahead of time不是一个句子而All the tasks had been fulfilled ahead of time 是一个句子?
答非所问!谓语是由助动词+谓语动词组成的,缺一不可
