以下仅仅是我个人的看法，不对的地方还望高手指正：
1.D.主语是employees, 后面的except是否定的并列成分，所以谓语还是用复数，用被动语态是“被鼓舞”
2.这一题是不是考小提琴的知识：好的小提琴，琴盒本身的共鸣音色就如同D弦弹奏的音色。不好意思，我也不清楚。
3.B.过去分子直接作后置定语。分析几个选项也能分析出来：A.将要被烧。C.主动态不对。D.正在烧。题目中知道火灾发生在40年前。
4.while表示转折，“她认为是...,然而...”。其他的词都没有这个意思。while转折的语气比but轻。
5.All you need 你所需要的是，补充完全就是all things that you need 你所需要的所有东西就是..其他选项不通。这里我也有个疑问：如果把all换成what，是不是也可以？
6.主语是动作的承受者，所以用被动态。还要分析动作的时间。C选项时“即将被吸引”。如果D变成“having been attracted”也对。直接用一个过去分词作定于或状语在英文中比较常见。如第3题和这一题。要注意总结。
7.针对第二人称的祈使句的反意疑问句。就是用will you？否定Don't 就用won't you?

哪位高手能告知第2题的解答，第5题的疑问，还有其他我解释不周到的地方。谢谢。
