几道BEC中级改错题,

我的改错非常不好,根本原因是语法不好,每次改错的12题,我得错一半.哎我也不知道该怎么办,从上中学开始,英语课都没听过,到高三的时候才开始猛背单词...语法真的是一塌糊涂.

关于这篇改错,我还有几个地方不懂,这些问题估计在别人看来都是再简单不过了吧...真是有点不好意思了

正确答案我有可我还有几个地方不明白

35.我觉得应该把havingalready该成havealready.可正确答案是这行没有错误...

37.为什么要把for去掉?usedforeachyear,我觉得也说得通啊

41.ifyouaresentan.这句子怎么解释?被动语态?如果是被动语态怎么翻译呐?难道是“如果你被发送了重要的邮件?、
