Detail 题
[1] Passive cooling architecture reduces indoor heat by relying on building design rather than heavy mechanical cooling. Features such as thick walls, shaded courtyards, and carefully placed openings can slow heat gain during the day. In some climates, these strategies make buildings more comfortable while lowering energy use.

[2] One widely used approach is to guide moving air through interior spaces. Ventilation towers, shaded passages, and high ceilings can direct breezes where they are most useful. Designers must also carefully channel air movement so that warm air leaves and cooler air enters at the right points.

[3] Although passive cooling depends on local climate and thoughtful planning, it is likely to become more important as cities search for lower-energy building strategies. For this reason, architects, engineers, and material specialists often work together when adapting traditional cooling ideas to modern construction.
Why are shaded courtyards and thick walls useful in passive cooling design?
  1. They help reduce indoor heat gain during the day.
  2. They eliminate the need for ventilation openings.
  3. They increase the amount of sunlight indoors at noon.
  4. They are useful only in cold climates.

Detail 题
Detail 题问的是文章中明确写出的信息。 正确答案在文中直接提到（而不是暗示），通常是一个具体的事实、数字或描述。
  • spellcheck Answer
    Answer: A

    (A) The correct answer is They help reduce indoor heat gain during the day. In the passage, "Features such as thick walls, shaded courtyards, and carefully placed openings can slow heat gain during the day." directly supports "They help reduce indoor heat gain during the day."

    (B) They eliminate the need for ventilation openings. is incorrect because it changes or distorts a detail from the passage; Features such as thick walls, shaded courtyards, and carefully placed openings can slow heat gain during the day.

    (C) They increase the amount of sunlight indoors at noon. is incorrect because the passage does not support that detail

    (D) They are useful only in cold climates. is incorrect because the passage does not support that detail

TOEFL 阅读题型 2：Gist Purpose（主旨目的题）

Gist Purpose 题问的是作者为什么写整篇文字。它主要出现在 Read in Daily Life 短文中，这类邮件或通知会在开头几句说明目的。对我们的学员来说，它是最容易的题型，正确率为 82.0%。陷阱是一个重复了文中某个真实细节、但并不是写这篇文字原因的选项。

Gist Purpose 题
[1] Fast radio bursts (FRBs) are extremely brief yet powerful flashes of radio energy that arrive without warning from distant reaches of the cosmos. Each signal lasts only a few milliseconds, so astronomers describe them as "ephemeral" events that fade almost as soon as they are noticed. Despite their fleeting nature, the bursts release more energy than the Sun does in days. Their dispersion patterns reveal that many originate billions of light-years away, implying that whatever produces them must be extraordinarily energetic and capable of sending signals across intergalactic space.

[2] Because FRBs travel through space for such vast stretches, they carry information about the material they traverse. By measuring slight delays at different frequencies, researchers can estimate the amount of ionized gas between galaxies. Leading theories about their origin include eruptions from magnetars, collisions between neutron stars, and the evaporation of primordial black holes. Magnetars attract particular attention because occasional X-ray flares from known examples coincide with weak FRB-like pulses, hinting at a physical connection.

[3] To unravel the mystery, astronomers are assembling networks of wide-field radio telescopes. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) already catalogs hundreds of bursts per year, while South Africa’s MeerKAT array pinpoints them to host galaxies. The forthcoming Square Kilometre Array (SKA) will boost sensitivity tenfold, enabling detection of weaker events and mapping the cosmic web with unprecedented detail. Paired with automated supercomputers, these facilities could transform FRBs from curiosities into routine tools for cosmology.
What is the purpose of the second paragraph?
  1. To describe the instruments used to detect FRBs
  2. To present major theories explaining FRB origins
  3. To compare FRBs with other cosmic explosions
  4. To summarize the history of radio astronomy

Gist Purpose 题
Gist Purpose 题问的是这篇文章（或其中一整部分）为什么而写。 正确答案表达的是作者的整体目的，而不是一个小细节。
  • spellcheck Answer
    Answer: B

    (B) The correct answer is to present major theories explaining FRB origins. Paragraph 2 lists “eruptions from magnetars, collisions between neutron stars, and the evaporation of primordial black holes,” clearly outlining leading hypotheses for where FRBs come from.

    (A) Discussion of detection instruments appears in paragraph 3, not paragraph 2, so this choice is inaccurate.

    (C) The paragraph does not compare FRBs with supernovae or gamma-ray bursts; it focuses solely on possible sources.

    (D) No historical overview of radio astronomy is provided; therefore this option is irrelevant.

TOEFL 阅读题型 3：Rhetorical Purpose（修辞目的题）

Rhetorical Purpose 题问的是作者为什么写进某个细节，而不是这个细节是否正确。你可以通过 "Why does the author mention..." 这样的措辞认出它。这个细节的作用通常在它前面的那句话里。我们的学员答对了 55.8% 的这类题，有 2 种题型比它难，7 种比它容易。

Rhetorical Purpose 题
[1] Mangrove forests grow along tropical and subtropical coastlines where saltwater and tides shape the landscape. Their roots trap sediment, stabilize shorelines, and create habitat for fish and invertebrates. These forests are especially valuable where coastal communities face regular storms and erosion.

[2] Mangroves can protect shorelines in several ways, including slowing incoming water, trapping debris, and buffering wave energy. For example, dense root systems can reduce the force of water moving toward land. In the same way a woven barrier spreads out pressure, tangled roots help weaken storm surges before they reach inland areas.

[3] Scientists study mangrove forests because they provide insight into how coastal ecosystems reduce environmental risk. Research on mangroves has improved shoreline models and helped scientists estimate how clearing these forests changes flooding patterns. These studies also help researchers distinguish the protective effects of vegetation from the effects of seawalls and other infrastructure.
Why does the author mention a woven barrier in the passage?
  1. To illustrate how mangrove roots can spread out and weaken wave force
  2. To suggest that coastal engineers copy mangrove roots exactly
  3. To compare storm surges with fishing equipment
  4. To show that woven barriers are better than forests in every case

Rhetorical Purpose 题
Rhetorical Purpose 题问的是作者为什么写进某个具体的细节、例子或短语。 答案不会直接写出来。你必须把题目提到的细节和这一段的主要观点联系起来。 你常常会看到这样的措辞：Why does the author mention ___?
  • spellcheck Answer
    Answer: A

    (A) The correct answer is To illustrate how mangrove roots can spread out and weaken wave force. In the passage, "In the same way a woven barrier spreads out pressure, tangled roots help weaken storm surges before they reach inland areas." shows why the author or speaker mentions that detail, so "To illustrate how mangrove roots can spread out and weaken wave force" is the best explanation of its function.

    (B) To suggest that coastal engineers copy mangrove roots exactly is incorrect because the author or speaker mentions the detail to support a different purpose, not this one

    (C) To compare storm surges with fishing equipment is incorrect because the author or speaker mentions the detail to support a different purpose, not this one

    (D) To show that woven barriers are better than forests in every case is incorrect because the author or speaker mentions the detail to support a different purpose, not this one

TOEFL 阅读题型 4：Vocabulary（词汇题）

Vocabulary 题问的是一个高亮单词在文章中的意思。你不需要事先认识这个单词，因为它周围的词几乎总会给出线索，比如 "or" 后面的重述、"but" 后面的对比，或下一句中的例子。我们的学员答对了 62.4% 的 Vocabulary 题，有 5 种题型比它难，4 种比它容易，所以只要你利用单词周围的线索，它们就能帮上忙。

[1] Some reef fish form partnerships in which small cleaner fish remove parasites and dead tissue from larger client fish. These interactions can improve the health of the clients and provide food for the cleaners. It was once assumed that such exchanges were merely routine, but researchers now recognize that they involve signals, repeated interactions, and choice.

[2] One well-known example involves cleaner wrasses and many different client species. When clients approach a cleaning station, they may slow down, hold still, or open their mouths and gill covers. These behaviors make it easier for cleaners to work efficiently while reducing the risk of injury.

[3] Researchers have also found that repeated encounters matter. Some clients return to cleaners that have treated them well in the past, while cleaners may adjust their behavior depending on who is waiting nearby. This pattern suggests that cooperation can be shaped by reputation and ongoing interaction. These findings continue to influence how scientists understand mutualism on coral reefs.

TOEFL 阅读题型 8：Select in Passage（选句题）

Select in Passage 题没有选项字母。你要在标出的段落中点击一个句子，而这个句子必须完整地回答问题。好几个句子都提到了这个话题，但只有一个给出了题目要的确切信息。我们的学员答对了 46.9% 的这类题，是全部十种题型中正确率最低的，所以做这类题时不要着急。

Select in Passage 题
[1] The theory of plate tectonics explains most of the Earth’s large-scale geological features, but it cannot fully account for the presence of isolated volcanic regions known as “hotspots.” These hotspots, such as those that created the Hawaiian Islands, appear in the middle of tectonic plates rather than along their boundaries. In 1963, geophysicist J. Tuzo Wilson proposed that plumes of unusually hot mantle material rise from deep within the Earth, partially melt near the surface, and generate chains of volcanoes as the overlying plate slowly drifts above them.

[2] For decades, the plume hypothesis was accepted with little reservation. However, improvements in seismic tomography have recently revealed that some supposed plume roots are shallower than originally assumed, lying only 200–300 kilometers beneath the crust instead of originating near the core-mantle boundary. In addition, geochemical analyses of hotspot lavas sometimes resemble mid-ocean-ridge basalts rather than the chemically distinct melts expected from deep mantle sources. These findings suggest that certain hotspots may instead form when lithospheric plates stretch and thin, allowing ordinary upper-mantle rock to melt more easily. Proponents of this “plate-driven” model point to the Iceland hotspot, where divergence along the Mid-Atlantic Ridge reduces pressure on the underlying mantle and promotes extensive volcanism without invoking a deep plume.

[3] Despite the debate, many geologists suspect that both mechanisms operate, with deep plumes explaining long, linear island chains and plate-driven melting accounting for broader volcanic provinces. Resolving the controversy matters because hotspot tracks are used to reconstruct past plate motions and to infer the thermal structure of the planet’s interior. New experiments that simulate mantle convection under realistic temperature and pressure conditions, combined with satellite measurements of surface deformation, may soon clarify whether the mantle behaves as a sluggish conveyor belt carrying discrete plumes or as a dynamic layer whose melting patterns primarily reflect stresses in the overlying plates.
Click on the sentence in paragraph 2 that describes the mechanism proposed by proponents of the 'plate-driven' model for hotspot formation.

  • spellcheck Answer
    Answer: “These findings suggest that certain hotspots may instead form when lithospheric plates stretch and thin, allowing ordinary upper-mantle rock to melt more easily.”

    (D) The correct answer is 'These findings suggest that certain hotspots may instead form when lithospheric plates stretch and thin, allowing ordinary upper-mantle rock to melt more easily.' This fourth sentence in paragraph 2 explicitly outlines the process suggested by proponents of the 'plate-driven' model, describing how plate stretching and thinning can allow for melting in the upper mantle, leading to hotspot formation.

    (A) The first sentence simply states that the plume hypothesis was accepted, not describing any alternative mechanisms.

    (B) The second sentence discusses new seismic tomography data about plume roots, not the plate-driven model's process.

    (C) The third sentence introduces geochemical findings, but it does not explain the mechanism by which plates could allow hotspot formation.

    (E) The sentence about the Iceland hotspot is incorrect because it gives an example supporting the model, not the general mechanism itself.

Insert a Sentence 题
[1] Spider silk is one of the most remarkable biological materials known to scientists. Different kinds of silk can be strong, flexible, lightweight, or sticky, depending on how a spider uses them. These fibers help spiders build webs, wrap prey, protect eggs, and move safely through their surroundings.

[2] One familiar type is dragline silk, which many spiders use as a structural thread in webs and as a safety line while climbing. Other silk strands are designed to capture prey by stretching easily and holding insects in place. Because spiders can produce several kinds of silk, they are able to use different fibers for different tasks.

[3] Researchers are studying spider silk proteins to develop new materials for medicine and engineering. [A] Some scientists hope to create fibers that mimic spider silk's combination of strength and flexibility for use in sutures, protective fabrics, and lightweight equipment. [B] Because natural spider silk is difficult to collect in large quantities, researchers are also testing ways to produce similar proteins in laboratories. [C] The study of spider silk not only improves our understanding of animal materials but also encourages practical innovation in many fields. [D]
