有許多同學在自修時，常不了解 GMAT 認可的規則要怎麼從題目判斷? 在這裡我們正好也有 FB 的同學詢問，我們就在此做個簡單介紹。

FB 原文: https://goo.gl/DRdPra

我們在此對 OG 本題直接截圖如下: 

雖然有時 GMAT 的慣用法並不是非常明確，但 OG 解釋的規則可以說是最接近 GMAT 出題的規則。在這裡 OG 指出，estimated 必須接 to be，而不能接 as。所以答案選 (D)

而同學問題如下:  

----------------------------------------------------------------------------------------

With surface temperatures estimated at minus 230 degrees Fahrenheit, Jupiter's moon Europa has long been considered far too cold to support life, and with 60 square miles of water thought to be frozen from top to bottom.

1. Europa has long been considered far too cold to support life, and with
2. Europa has long been considered far too cold to support life, its
3. Europa has long been considered as far too cold to support life and has
4. Europa, long considered as far too cold to support life, and its
5. Europa, long considered to be far too cold to support life, and to have        
                                                                                                     Answer: B

----------------------------------------------------------------------------------------

在沒有畫線的部分，用了 estimated at。這是否代表 estimated 也能使用 at? 
在這裡，必須要先跟同學說，GMAC 如果在 OG 說過的規則，在答案選項會錯的機率不高 (請看清楚，是不高，但不是絕對)

但在某些情形，GMAT 在出題時，是相對不會關注的規則用法，我們就拿 "in that" 來當我們的例子好了

GMAT 認為如果 in that 當連接詞，已經是不適用的用法了。然而，我們可以在下面兩個地方看到: 

1. 未畫線的部分: 

----------------------------------------------------------------------------------------

Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).

1. acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate
2. acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating
3. act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating
4. they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates
5. they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate

                                                                                                          Answer: A

----------------------------------------------------------------------------------------

在未畫線的部分中，其實我們常看到 GMAT 出題並不是非常仔細，常會出現一些官方解釋中不偏好的使用方法。如此題的 in that，出現在沒有畫線部分當中當連接詞。

2. 出現在所有答案選項當中

----------------------------------------------------------------------------------------

A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would fail if the density of the timber wolf population in that region is more numerous than one wolf for every 39 square miles.

1. would fail if the density of the timber wolf population in that region is more numerous
2. would fail provided the density of the timber wolf population in that region is more
3. should fail if the timber wolf density in that region was greater
4. will fail if the density of the timber wolf population in that region is greater
5. will fail if the timber wolf density in that region were more numerous                  

                                                                                                                  Answer: D

----------------------------------------------------------------------------------------

在此題當中，我們發現五個答案選項都有 in that 當連接詞的用法。

如果在 GMAT 題目當中，都會放入不正確的使用方式，我們應該怎麼去抓出正確答案的使用方式呢? 

我們在此也提供兩項建議: 

1. 以正確答案選項及畫線部分的使用方式為主

有同學常注意未畫線的使用方式，基本上未畫線的部分，出題者只是提供線索來讓同學解出正確答案，也因此相對來說，會比較不去避免使用不偏好的文法使用方式。因此，我們會建議，專注在正確答案、且是畫線部分所使用的用法。

2. 專注在正確答案與錯誤選項的差別

GMAT 出題時，也許可能已經將考點先設計好，將不偏好、或錯誤的使用方式放在錯誤答案，正確答案盡量避免。不過，在一開始沒預期到的考點當中，可能正確答案就會放入不偏好的使用方式。

所以我們有時會看到，在正確答案出現 GMAT 所不接受的規則。但通常不會發生 "只有正確答案有不接受的規則" 的情形。

在此提供同學作研究 SC 規則統整的一個參考。
