B。
fully accepted
我选B,答案A
===================解答:我个人认为,这一题,可以选B,因为before 可以理解为连词,引导一个时间状语从句,且其从句主语等于主句主语new ideas,此时可以省略从句的主语和系动词。
----------至于答案给的A,则是把before当介词处理,后面跟动名词形式。
45。Even if_____harder,Mike still has trouble with the subject of maths。
A。working B。works
我觉得应该是even if he works或者Having worked
========================解答:even if从句可以虚拟也可以不虚拟,这里应该不是虚拟。
如同上一题,状语从句,从句主语同主句主语一致,可以省略从句“主语+系动词”,形成“even if + 分词”。
至于你所说的even if he works harder,可以。这就是解释为什么不能选B。
----不过主句用将来时更好。
至于Having worked-----Having worked harder,Mike still has trouble with the subject of maths。
---这个句子逻辑有问题,因为having worked 这里现在分词完成式,作状语,表原因或者时间,但主句意思却与之相悖:麦克一直很努力,他在数学上仍有问题。(差一个转折词)
