一语法题
he offered us a gift when he was leaving the office,but our work______,we declined the offer. a.not being finished b.not having finished c.had not been finished d.was not finished 请讲明原因 谢谢!!
我选 a.but是一个连词,连接了两个句子:第一句是he offered us a gift when he was leaving the office;后面的句子是:our work not being finished,we declined the offer.后面的句子有点复杂.其中our work not being finished是动词的ing结构,作原因状语,主句是we declined the offer.因为主语不一致,故not being finished前面的our work是动作的逻辑主语.它们是被动关系.
我选a,这里是个插入与的成分故要用非谓语的结构,而our work 要用到被动,综合可得答案应该是a.
在表达否定意思的时候,not是放在所有其他单词前的. 所以c,d排除. but 引导的句子是以our work 为主语,所以工作被完成要用被动,而b中就是主动的.
答:1.a 本句意思是"既然我不会读写,我怎么能得到一份工作呢?",when表示明显的,已是事实的原因,等于since/ cause表示的是直接的强烈的原因. W...详情>>
