Section 2：Structural Reading Method

2.1 Map the Structure, Not Every Detail（抓結構，不摳細節）

GRE RC 的核心策略是 結構式閱讀 (Structural Reading)。你不需要記住每一個細節，只需要理解文章的邏輯骨架。

三步驟方法：

步驟	動作	時間
Step 1	讀首段首句和末句	5 秒
Step 2	讀每段的首句，標記功能（主張、證據、反駁、結論）	20 秒
Step 3	形成心智地圖 (mental map)：主題 → 結構 → 作者態度	10 秒

心智地圖範例：

Topic: 海洋酸化
Structure: 現象 → 原因 → 後果 → 解決方案
Attitude: 擔憂但謹慎樂觀

2.2 段落功能標記法

閱讀時用符號標記每段功能：

符號	功能	範例
C	Claim / 主張	”This paper argues that…”
E	Evidence / 證據	”Studies show…” / “Data indicate…”
R	Rebuttal / 反駁	”However, this view overlooks…”

Section 4：GRE-Style Passages

GRE Passage 1：Phenomenon — Ocean Acidification

The world’s oceans have absorbed approximately 30 percent of the carbon dioxide (CO2) released by human activities since the Industrial Revolution. While this absorption has helped mitigate the effects of climate change on atmospheric temperatures, it has come at a significant cost: the chemistry of the oceans is changing. When CO2 dissolves in seawater, it forms carbonic acid, lowering the water’s pH. Since the late 18th century, the average pH of ocean surface waters has decreased by approximately 0.1 units — a change that, because the pH scale is logarithmic, represents roughly a 26 percent increase in acidity.

The consequences of ocean acidification are particularly alarming for organisms that build shells or skeletons from calcium carbonate, including corals, oysters, clams, and certain species of plankton. As acidity increases, the concentration of carbonate ions in the water decreases, making it more difficult for these organisms to construct and maintain their protective structures. Laboratory experiments have shown that under projected acidity levels for the year 2100, some shellfish will be unable to form shells at all.

Some researchers have questioned the severity of these predictions, noting that certain marine organisms have shown a remarkable capacity to adapt to changing conditions. Deep-sea corals, for example, have survived periods of high atmospheric CO2 in the geological past. However, the current rate of acidification is unprecedented in at least 300 million years, and adaptation typically requires many generations — a luxury that many species may not have.

Structural Analysis:

P1: Phenomenon (ocean acidification) — description and scale
P2: Consequence — impact on shell-building organisms
P3: Counterargument + Rebuttal — adaptation possible but rate too fast
Author's Attitude: concerned, scientifically cautious

Questions:

1. The primary purpose of the passage is to ___. (A) argue that ocean acidification is the most serious environmental problem (B) describe the phenomenon of ocean acidification and evaluate its potential consequences (C) compare different methods of measuring ocean acidity (D) challenge the theory that CO2 affects ocean chemistry

2. The author mentions “a 26 percent increase in acidity” primarily in order to ___. (A) illustrate that a seemingly small pH change represents a significant chemical shift (B) show that the pH scale is easy to understand (C) prove that scientists have been measuring acidity correctly (D) suggest that 26 percent is an acceptable level of change

3. The author’s response to researchers who question the severity of ocean acidification is that ___. (A) their research is methodologically flawed (B) past episodes of high CO2 were less severe than the current one (C) the current rate of change may be too rapid for adaptation (D) deep-sea corals are not relevant to the discussion

GRE Passage 2：Multiple Viewpoints — Nature vs. Nurture

The debate over whether intelligence is determined primarily by genetics (nature) or by environment (nurture) has persisted for over a century. In the early 20th century, the nature perspective dominated, fueled by the eugenics movement and studies of identical twins raised apart. These studies appeared to show that twins raised in different environments still exhibited remarkably similar cognitive abilities, suggesting a strong genetic basis for intelligence.

In the 1960s and 1970s, the nurture perspective gained prominence. Psychologists such as Richard Lewontin argued that environmental factors — including nutrition, education, and socioeconomic status — played a far larger role than genetics in determining cognitive outcomes. Lewontin pointed out that most twin studies involved twins raised in relatively similar environments, even when separated, because adoption agencies typically placed children in families of comparable socioeconomic backgrounds. This placement bias, he contended, inflated the apparent influence of genetics.

Modern researchers have largely moved beyond the nature-versus-nurture dichotomy, recognizing that intelligence arises from a complex interaction between genetic predispositions and environmental influences. Studies now suggest that heritability of intelligence increases with age — a counterintuitive finding known as the “Wilson Effect.” One explanation is that as people grow older, they increasingly select environments that match their genetic predispositions, amplifying the apparent role of genes.

Structural Analysis:

P1: Viewpoint A (nature) — early 20th century, twin studies
P2: Viewpoint B (nurture) — 1960s-70s, Lewontin's criticism
P3: Synthesis (interaction) — modern view, Wilson Effect
Author's Attitude: objective, synthesizing

Questions:

1. The passage suggests that Lewontin would agree with which of the following? (A) Twin studies provide strong evidence for genetic determinism. (B) Adoption agencies in the mid-20th century were well-managed. (C) Twin studies overestimated the role of genetics due to placement bias. (D) Identical twins always have identical intelligence.

2. The “Wilson Effect” described in the passage refers to the finding that ___. (A) environmental factors become less important over time (B) the heritability of intelligence increases with age (C) twins raised apart are always different (D) genetic factors are irrelevant to intelligence

3. The passage is organized by ___. (A) presenting two opposing views and then a synthesis (B) describing a single experiment in detail (C) arguing strongly for the nature position (D) listing statistical data chronologically

GRE Passage 3：Book Review — Rewriting History

In her controversial book The Myth of the Andalusian Paradise (2016), historian Darío Fernández-Morera challenges the widely held belief that medieval Muslim-ruled Spain (al-Andalus) was a model of interfaith harmony and cultural flourishing. According to the conventional narrative, Muslims, Christians, and Jews coexisted peacefully in al-Andalus, producing remarkable advances in science, philosophy, and the arts. Fernández-Morera argues that this narrative is largely a romanticized fiction.

Drawing on primary sources in Arabic, Latin, and Spanish, Fernández-Morera contends that life for non-Muslims in al-Andalus was characterized by systematic discrimination, periodic violence, and the constant threat of persecution. She points to historical records showing that Christians and Jews were required to pay special taxes, were prohibited from building new places of worship, and were subject to sumptuary laws that restricted their clothing and public behavior.

Several scholars have criticized Fernández-Morera’s work for what they see as an overly negative portrayal that replaces one simplified narrative with another. Historian Brian Catlos, while acknowledging the value of Fernández-Morera’s archival research, argues that her account understates the genuine moments of cultural exchange and cooperation that did occur. The reality, Catlos suggests, was neither a paradise nor a nightmare but a complex society in which tolerance and intolerance coexisted uneasily.

Structural Analysis:

P1: Book's thesis — challenges conventional narrative
P2: Book's evidence — discrimination records
P3: Criticism — oversimplification in the other direction
Author's Attitude: balanced, presenting the debate without taking sides

Questions:

1. The primary purpose of the passage is to ___. (A) praise Fernández-Morera’s groundbreaking research (B) describe a scholarly debate about the nature of medieval Spain (C) prove that al-Andalus was a violent society (D) compare Muslim and Christian civilizations

2. According to the passage, Catlos’s main criticism of Fernández-Morera is that ___. (A) her archival research is unreliable (B) she cannot read Arabic sources (C) her account replaces one oversimplification with another (D) she focuses too much on cultural achievements

3. The author of the passage would most likely characterize the conventional narrative about al-Andalus as ___. (A) completely accurate (B) entirely false (C) an oversimplification that contains some truth (D) irrelevant to modern scholarship

GRE Passage 4：Argument — Universal Basic Income

The concept of Universal Basic Income (UBI) — a regular, unconditional cash payment to every citizen — has gained significant traction in recent years. Proponents argue that UBI would eliminate poverty, reduce bureaucracy, and provide workers with greater bargaining power in the labor market. A landmark experiment in Finland from 2017 to 2018, in which 2,000 unemployed citizens received a basic monthly payment, appeared to support these claims: recipients reported improved well-being, reduced stress, and slightly higher employment rates compared to the control group.

Critics, however, raise several objections. First, they question whether UBI is financially sustainable at a national scale. Providing every American adult with $12,000peryear,forexample,wouldcostapproximately$3 trillion annually — roughly 75 percent of current federal revenue. Second, they argue that UBI could discourage work, particularly among low-wage workers who might choose to live on the basic income rather than accept undesirable jobs. Third, critics contend that UBI, by distributing money universally rather than targeting those most in need, is an inefficient use of limited resources.

The debate is further complicated by the question of whether UBI should replace or supplement existing welfare programs. Some advocates propose UBI as a complete substitute for all other social benefits, arguing that the simplicity of a single universal payment would reduce administrative costs and eliminate the stigma associated with means-tested programs. Others worry that eliminating targeted programs could leave vulnerable populations — such as the disabled or those with high medical costs — worse off than before.

Structural Analysis:

P1: Argument for UBI — with Finland evidence
P2: Arguments against — cost, work disincentive, inefficiency
P3: Additional complexity — replace vs. supplement existing programs
Author's Attitude: neutral, presenting balanced analysis

Questions:

1. According to the passage, the Finland experiment showed that UBI recipients ___. (A) stopped looking for work entirely (B) experienced improved well-being and slightly higher employment (C) spent all the money on unnecessary items (D) were no different from the control group

2. The author mentions the cost of “$3 trillion annually” primarily to ___. (A) suggest that UBI is affordable (B) illustrate the financial challenge of implementing UBI nationally (C) argue for higher taxes (D) compare the U.S. economy to Finland’s

3. It can be inferred that the author views the UBI debate as ___. (A) settled in favor of UBI (B) settled against UBI (C) complex and unresolved, with valid arguments on both sides (D) irrelevant to modern policy

GRE Passage 5：Phenomenon — The Placebo Effect

The placebo effect — the phenomenon in which patients experience real improvements after receiving an inert treatment — has long fascinated and frustrated medical researchers. In clinical trials, placebos are used as a baseline to measure the effectiveness of new drugs. Yet the placebo effect itself is surprisingly powerful: studies have shown that placebos can alleviate pain, reduce symptoms of depression, and even affect measurable physiological indicators such as blood pressure and heart rate.

Traditionally, the placebo effect was attributed to patients’ beliefs and expectations. If a patient believed that a pill would help, the theory went, the brain would initiate healing responses that produced genuine relief. However, recent research has revealed a more complex picture. In a striking 2010 study, researcher Ted Kaptchuk found that patients with irritable bowel syndrome experienced significant improvement even when they were explicitly told that they were receiving a placebo. This “open-label placebo” effect suggests that the therapeutic benefits of placebos cannot be explained entirely by patient belief.

Several mechanisms have been proposed to account for the placebo effect. Classical conditioning may play a role: patients who have previously experienced relief from medication may unconsciously associate the act of taking a pill with healing, triggering the same physiological responses even when the pill is inert. The patient-practitioner relationship also appears to be important: patients who feel cared for and listened to tend to show stronger placebo responses, suggesting that the social and emotional context of treatment matters as much as the treatment itself.

Structural Analysis:

P1: Phenomenon — description of the placebo effect
P2: Challenge to traditional theory — open-label placebo study
P3: Proposed mechanisms — conditioning and patient-practitioner relationship
Author's Attitude: intellectually engaged, presenting evolving understanding

Questions:

1. The passage suggests that the traditional explanation for the placebo effect is ___. (A) completely wrong (B) sufficient to explain all placebo responses (C) incomplete and needing revision (D) unrelated to modern medicine

2. The Kaptchuk study is significant because it shows that ___. (A) placebos never work (B) patients must be deceived for placebos to work (C) placebos can work even when patients know they are receiving them (D) irritable bowel syndrome cannot be treated

3. According to the passage, which of the following may contribute to the placebo effect? (A) The color of the pills (B) Classical conditioning and the patient-practitioner relationship (C) The cost of the medication (D) The patient’s knowledge of pharmacology
