為什麽說機考SAT是降維版本的GRE/GMAT

首先在語法（官方叫Writing）的考察上不管是紙質版本的SAT，還是目前機考的SAT 都是比GMAT 的SC （同樣涉及語法）部分容易很多。

一個(ge) 直觀的比較是，SAT 的題目用一個(ge) 知識點就可以排除3個(ge) 選項的，但是GMAT 的SC 往往一個(ge) 題目裏考的不僅(jin) 僅(jin) 是一個(ge) 知識點。

比如

[Digital SAT] Formed in 1967 to foster political and economic stability within the Asia-Pacific region, the Association of Southeast Asian Nations was originally made up of five members: Thailand, the Philippines, Singapore, Malaysia, and Indonesia. By the end of the 1990s, the organization ______ its initial membership.

Which choice completes the text so that it conforms to the conventions of Standard English?

has doubled
had doubled
doubles
will double

就是考時態這一個(ge) 知識點，時間點（the end of the 1990s）的給出也是很直接

[GMAT] The results of the company's cost-cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.

which increased five percent during the first three months of this year after it fell
which had increased five percent during the first three months of this year after it had fallen
which have increased five percent during the first three months of this year after falling
with a five percent increase during the first three months of this year after falling
with a five percent increase during the first three months of this year after having fallen

找了一個(ge) 和第一個(ge) SAT 的題目考察點很接近的GMAT SC 的題目，也是考時態，隻是從(cong) 選項的複雜度上來說會(hui) 高一些，另外時間點的給出也沒有那麽(me) 直接，GMAT 的還是有一個(ge) after 的前後時間擾亂(luan) 。‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

當然兩(liang) 題都不是對應考試裏麵的難的題目，隻是從(cong) 以上同類型知識點的考察可以看出來兩(liang) 個(ge) 考試在能力要求上的不同。‍‍‍‍‍‍‍‍

在機考SAT 閱讀方麵也是‍‍‍‍‍‍‍‍‍‍

閱讀的填空GRE 有類似的考題，不管是詞匯量的考察還是句子的閱讀難度上，GRE 的填空都會(hui) 更難一些。

[Digital SAT] The author’s claim about the relationship between Neanderthals and Homo sapiens is ______, as it fails to account for several recent archaeological discoveries. To be convincing, his argument would need to address recent finds of additional hominid fossils, such as the latest Denisovan specimens and Homo longi.

Which choice completes the text with the most logical and precise word or phrase?

disorienting
tenuous
nuanced
unoriginal

[GRE] In one theory, as people learn things throughout the day, connections between neurons get strengthened, but during sleep then all synapses are weakened, tenuous connections are _____ and only the strongest bonds could remain.

reinforced
reproduced
replaced
stimulated
severed

在單空題目方麵，GRE 的空格重複會(hui) 更為(wei) 直截了當些，SAT 的語境會(hui) 更為(wei) 完整些，直觀來看，就是題目會(hui) 字數多些。從(cong) 目前官方給出的SAT 填空題目來看，雖然題目長，但陌生詞是比較少的，長出來的部分大多是在幫我們(men) 更好的理解題目內(nei) 容。‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

GRE 也有長題的填空，隻是這個(ge) 時候挖的空就會(hui) 多些‍‍‍

The power of laughter to affect the perceived funniness of television programming is (i) _______: most researchers have found that the inclusion of laughter on a program's soundtrack (ii) _______ the overall perception of humor, although it appears that it can (iii) _______ humor at specific points and thus boost the total comic appeal of the program.

cumulative measurable unclear
allows variations in tends to accentuate has little effect on
dampen enhance mask

另外機考SAT 的閱讀部分還有類似GRE/GMAT 邏輯部分的考題。

機考SAT 的證據題

[Digital SAT] Jan Gimsa, Robert Sleigh, and Ulrike Gimsa have hypothesized that the sail-like structure running down the back of the dinosaur Spinosaurus aegyptiacus improved the animal’s success in underwater pursuits of prey species capable of making quick, evasive movements. To evaluate their hypothesis, a second team of researchers constructed two battery-powered mechanical models of S. aegyptiacus, one with a sail and one without, and subjected the models to a series of identical tests in a water-filled tank.

Which finding from the model tests, if true, would most strongly support Gimsa and colleagues’ hypothesis?

The model with a sail took significantly longer to travel a specified distance while submerged than the model without a sail did.  
The model with a sail displaced significantly more water while submerged than the model without a sail did.  
The model with a sail had significantly less battery power remaining after completing the tests than the model without a sail did.  
The model with a sail took significantly less time to complete a sharp turn while submerged than the model without a sail did.

‍從(cong) 做題原則上來說，就是在題目裏麵有個(ge) 結論，然後需要我們(men) 在選項裏麵找個(ge) 證據能去支持文本裏的結論。所謂的“支持”，就是重複（比如上麵黃色highlight 部分的對應）。

GMAT 的邏輯題‍

[GMAT] In an experiment, psychologists tracked the eye movements of adults and of infants from four to twelve months old watching a video of a woman speaking. The adults and the infants younger than six months mainly watched the woman's eyes, but the infants older than six months switched their attention between her eyes and her mouth. The psychologists concluded that lip-reading plays a role in how most infants learn language.

Which of the following would, if true, most strengthen the support for the psychologists' conclusion?

Most infants start the process of learning language when they are about four months old.
Watching people's eyes and facial expressions also plays a substantial role in how most infants learn language.
Watching the woman's mouth did not help the adults or the youngest infants understand what she was saying.
While watching the woman's lips, the infants older than six months repeated the vocal sounds she made then more often than those she made at other times.
The infants generally paid closer attention to the video when the woman's mouth was concealed than when her eyes were concealed.

上麵GMAT 的這個(ge) 題目和前麵Digital SAT的題目在題幹和答案的製造上是比較像的：1. 都是加強 2. 都是答案提供了一個(ge) 更為(wei) 細節的內(nei) 容和題幹中的籠統觀點對應重複。

這個(ge) Evidence的題型，不管是Digital SAT 還是 GMAT 都有Weaken 類型的：就是在選項裏麵找個(ge) 證據去削弱題幹中的結論。

GMAT 和 Digital SAT 不同的地方是， GMAT 的考察的邏輯的豐(feng) 富度會(hui) 更高些（在選項的加強和削弱的表達上會(hui) 更為(wei) 複雜）；Digital SAT 在這個(ge) 題型上也有自己的特點，它會(hui) 考場詩歌和小說內(nei) 容的證據題，這是研究生考試沒有的，比如

“Ghosts of the Old Year” is an early 1900s poem by James Weldon Johnson. In the poem, the speaker describes experiencing an ongoing cycle of anticipation followed by regretful reflection: ______

Which quotation from “Ghosts of the Old Year” most effectively illustrates the claim?

“The snow has ceased its fluttering flight, / The wind sunk to a whisper light, / An ominous stillness fills the night, / A pause—a hush.”
“And so the years go swiftly by, / Each, coming, brings ambitions high, / And each, departing, leaves a sigh / Linked to the past.”
“What does this brazen tongue declare, / That falling on the midnight air / Brings to my heart a sense of care / Akin to fright?”
“It tells of many a squandered day, / Of slighted gems and treasured clay, / Of precious stores not laid away, / Of fields unreaped.”
