28　Spend time beating on a wall, hoping to change it into a door.
的否定祈使句.说的是,有的人也时间花在不停地拍打一堵墙上,希望这样能将它变成一扇门.当然这是不可能的,是在浪费时间.
这一题最大的干扰项是D.不定式作目的状语不行吗?
如果用不定式作目的状语,则1.置后不用逗号.2.　去掉hope,直接说　to change it ...
我们说：为了改变而做某事,不说：为了希望去改变而做,但可以说：在做的同时,心里想着,希望着要将墙壁变成门.理解这个,需要一定的逻辑思维能力.不多说了,记住,这种情况,用hoping ..., 不用to hope...
29. A man can fail many times, but he isn’t a failure he begins to blame somebody else.
A. even B. until C. in case D. once
答案B
译：一个人可以失败很多次,但是他不是一个失败者,直到他开始责怪别人.
析：考查从属连词,考逻辑.代进去翻译一下,就可以知道,B最佳.not ...until...
如果用D,则为：He is a failure once he ..., 他一旦.,就是一个失败者.
你最好有自己的选择,这样讲更有针对性.谁知道你的水平如何,能排除几个呢?总不能个个都讲吧?
31. Mere words cannot match the depths of our sorrow, our wounded hearts.
A. nor they can heal B. so they can heal C. nor can they heal D. so can they heal
答案C
答：否定的情况适用于后者,用Nor/Neither+助动词+主语（倒装）,排除CD
A没有倒装,排除.
译：语言不能表达我们的悲伤,也不能医治我们受伤的心.
32. you look into your heart that your vision will become clear.
A. It is only when B. Only when C. When it is only D. Only when it is
答案A
答：这是强调句.去掉强调结构词,it is . that, 原句为：your vision will become clear only when you look into your heart.
值得注意的是,如果only +状语（从句）放句首,主句要部分倒装：
Only when you look into your heart will your vision become clear.
