??在做題的時候將做錯的，有疑惑的，正確答案比較奇特的按照幾類分一下，我的分法是：support/weaken/evaluate為一類，assumption/must be true/conclusion為一類，其他所有題型(如填空，flaw,etc。
??)為一類。(或將他們再細分，總之按照自己喜歡的方式都行)分類部不是簡單的將整道題目完全放上去，而是將有特點的選項放上去，那些一看就是錯的選項就可以直接無視(上面語法部分也是一樣，i。e。將那些自己已經明白的選項剔出)，然后反復讀，體會。重中之重是OG的解釋一定要細看，在GWD，prep上遇到有疑惑的題了一定要回到OG上找類似的題目，看解釋，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
這題我當初第一次做的時候選E,因為我覺得就是因為limited才能有市場上升的空間，后來找到了OG上一道有些神似的題將我的疑惑解開了：
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的解釋：This also weakens the hypothesis, because it states that there is no known evidence of a certain type that would support the hypothesis。
??)
從這個解釋可以推出OG認為No musical instrument that is known或者the current market for solar-power generators in the United States is very limited應該直接去理解而不是間接的去推測，就是說應該直接理解is very limited。
??所以美國太陽能那題E錯在起了weaken的作用。
