在做题的时候将做错的，有疑惑的，正确答案比较奇特的按照几类分一下，我的分法是：support/weaken/evaluate为一类，assumption/must be true/conclusion为一类，其他所有题型(如填空，flaw,etc。
  )为一类。(或将他们再细分，总之按照自己喜欢的方式都行)分类部不是简单的将整道题目完全放上去，而是将有特点的选项放上去，那些一看就是错的选项就可以直接无视(上面语法部分也是一样，i。e。将那些自己已经明白的选项剔出)，然后反复读，体会。重中之重是OG的解释一定要细看，在GWD,prep上遇到有疑惑的题了一定要回到OG上找类似的题目，看解释，理解OG的思路，例如：

　　United States manufacturers currently produce most of the world's solar-power generators--most of which are exported to Europe。
  However, European manufacturers are emerging and probably will ultimately capture much of the European market。The United States government is funding initiatives intended to encourage use of solar power within the United States。
  If these initiatives succeed in increasing the demand for solar-power generators in the United States, United States manufacturers will probably maintain significant production levels, since __________。
  

　　(C) just as European manufacturers enjoy certain competitive advantages in Europe, so do United States manufacturers in the United States

　　(E) the current market for solar-power generators in the United States is very limited

　　这题我当初第一次做的时候选E,因为我觉得就是因为limited才能有市场上升的空间，后来找到了OG上一道有些神似的题将我的疑惑解开了：

　　The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance。
   Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians。
  

　　Which of the following, if true, most strongly supports the hypothesis?

　　(E) The cave-bear leg bone used to make the Neanderthal flute would have been long enough to make a flute capable of playing a complete diatonic scale。
  

　　(B) No musical instrument that is known to have used a diatonic scale is of an earlier date than the flute found at the Neanderthal campsite。
  (OG的解释：This also weakens the hypothesis, because it states that there is no known evidence of a certain type that would support the hypothesis。
  )

　　从这个解释可以推出OG认为No musical instrument that is known或者the current market for solar-power generators in the United States is very limited应该直接去理解而不是间接的去推测，就是说应该直接理解is very limited。
  所以美国太阳能那题E错在起了weaken的作用。

　　反复读很多遍以后会有一种感觉，这种感觉就是隐隐约约感觉出正确答案的方向。(这里我要强调一下方向两个字，虽然正确答案是一个，但任何题目的潜在正确答案都有很多个，例如support的方法包括例证，排除其它原因，加强premise-conclusion之间的联系等等，所以感觉的是方向而不是正确答案)在今天的考试中我几乎所有的逻辑题都不到一分钟就能解决。
  原意有两个，一个是已经看了寂静,另外一个就是有了那种有些模糊“预知”感觉。
