✿GMAT-Reading 解題秘訣要領(tips) : 
Tip 1: 審視題幹 (scrutinize statements of questions) --- 審慎閱讀問題之陳述, 理解題目所要求之目的。
Tip 2: 搜索關鍵字詞 (search for key words) --- 掌握題幹中所提示之訊息, 並搜索題目之關鍵核心字詞(key words/ phrases)。
Tip 3: 定位 (positioning / locating) --- 回溯關鍵詞所在之原文進行定位。
Tip 4: 判讀與分析(Judgment / Analysis) --- 慎思與通透明瞭句中之論述, 並善用字裡行間之訊息傳遞, 俾以判斷並比對與選項之吻合度。
***老師以以下篇章示範解題技巧 : 

Perhaps the least controversial assertion about the pterosaurs is that they were reptiles.  Their skulls, pelvises, and hind feet are reptilian.  The anatomy of their wings suggests that they did not evolve into the class of birds.  In pterosaurs a greatly elongated fourth finger of each forelimb supported a wing-like membrane.  The other fingers were short and reptilian, with sharp claws.  In birds the second finger is the principal strut of the wing, which consists primarily of feathers.  If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping.

1. It can be inferred from the passage that scientists now generally agree that the
(A) enormous wingspan of the pterosaurs enabled them to fly great distances
(B) structure of the skeleton of the pterosaurs suggests a close evolutionary relationship to bats
(C) fossil remains of the pterosaurs reveal how they solved theproblem of powered flight
(D) pterosaurs were reptiles
(E) pterosaurs walked on all fours

解題步驟 :
1. 搜索關鍵核心字詞 (key words) → scientists generally agree
2. 定位 (positioning / locating)→ the least controversial assertion
3. 判讀訊息: Perhaps the least controversial assertion about the pterosaurs is that they were reptiles.
4. 對應選項 (correlation) →正確答案 D .

***同義字詞補充 : 
1. pterosaur  (翼龍)   pelvis   (骨盆)   anatomy  (解剖)   reptile (爬蟲類)
2. agree (同意) = consent = assent = accede = acquiesce
3. assert (斷言) = asseverate = affirm = aver

The pterosaurs resembled both birds and bats in their overall structure and proportions.  This is not surprising because the design of any flying vertebrate is subject to aerodynamic constraints.  Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight.  In the birds, however, these bones are reinforced more massively by internal struts.

2. According to the passage, the skeleton of a pterosaur can be distinguished from that of a bird by the
(A) size of its wingspan
(B) presence of hollow spaces in its bones
(C) anatomic origin of its wing strut
(D) presence of hooklike projections on its hind feet
(E) location of the shoulder joint joining the wing to its body

***解題步驟 :
1. 搜索關鍵核心字詞 (key words)→ skeleton  / distinguished  / pterosaurs / birds
2. 定位 (positioning / locating)→ Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced  more massively by internal struts.
skeleton = bone
3. 判讀訊息: distinguish (區別): 分析差異性 ;  前敘述為both 兩者共通特質; however 文意轉折: 即為pterosaurs / birds 差異處.
4. 對應選項 (correlation) :  internal strut = wing strut . → 正確答案C.

***同義字詞補充 : 
1. strut  (支柱/支撐)  
2. distinguish (區別/ 分辨) = differentiate = discern = discriminate = tell
3. reinforce  (強化) = strengthen = fortify = enhance = intensify = boost
4. massive  (巨大的) = huge = immense = enormous = tremendous = colossal = gigantic = titanic = vast = mammoth = prodigious
