Quanti tipi di domande ci sono nel TOEFL Reading?

Nel TOEFL Reading ci sono dieci tipi di domande. Nove sono domande a scelta multipla o domande in cui clicchi nel testo, su un testo di Read in Daily Life o su un testo accademico. Il decimo, Complete the Words (completa le parole), è un testo a sé con parole da completare. La tabella mostra quanto spesso i nostri studenti rispondono bene a ogni tipo durante la pratica, dal più difficile al più facile.

I quattro tipi più difficili per i nostri studenti sono Select in Passage, Insert a Sentence, Rhetorical Purpose e Negative Factual Information. Select in Passage non ha lettere di risposta e ti chiede di cliccare una frase; Insert a Sentence non ha lettere di risposta e ti chiede di inserire una frase; Rhetorical Purpose chiede perché l'autore ha inserito un dettaglio; Negative Factual Information chiede l'unica scelta che nel testo non c'è. I due tipi più facili sono Gist Purpose, con l'82.0% di risposte corrette, e Detail, con il 74.7%, e compaiono entrambi nei testi di Read in Daily Life. Alcuni tipi sono anche diventati più facili quando i testi sono diventati più brevi, a gennaio 2026. Il cambiamento più grande è stato quello di Inference, che è salito dal 47.4% al 71.7% di risposte corrette. Nella nostra guida al Reading trovi le domande di TOEFL Reading vecchie e nuove a confronto.

Tipo di domanda TOEFL Reading 1: Detail

Una domanda Detail (dettaglio) del TOEFL Reading ti chiede un fatto che il testo dice chiaramente. Trovi la frase che contiene il fatto e scegli la risposta che dice la stessa cosa con altre parole. Le domande Detail compaiono sia nei testi di Read in Daily Life sia nei testi accademici, e i nostri studenti rispondono bene al 74.7% delle domande Detail durante la pratica: 8 tipi sono più difficili e 1 è più facile. Per questo è uno dei posti migliori dove guadagnare punti.

Domanda Detail
[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.

Domanda Detail
Le domande Detail chiedono un'informazione che il testo dice in modo chiaro. La risposta corretta è scritta nel testo (non solo suggerita), spesso come un fatto, un numero o una descrizione precisa.
  • 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

Tipo di domanda TOEFL Reading 2: Gist Purpose

Una domanda Gist Purpose (scopo generale) ti chiede perché l'autore ha scritto tutto il testo. Compare soprattutto con i testi di Read in Daily Life, dove un'email o un avviso dice il suo scopo nelle prime frasi. Per i nostri studenti è il tipo più facile, con l'82.0% di risposte corrette. La trappola è una scelta che ripete un dettaglio vero del testo, ma che non è il motivo per cui il testo è stato scritto.

Domanda Gist Purpose
[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

Domanda Gist Purpose
Le domande Gist Purpose chiedono perché è stato scritto il testo (o una sua parte intera). La risposta corretta esprime l'obiettivo generale dell'autore, non un piccolo dettaglio.
  • 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.

Tipo di domanda TOEFL Reading 3: Rhetorical Purpose

Una domanda Rhetorical Purpose (scopo retorico) ti chiede perché l'autore ha inserito un dettaglio, non se il dettaglio è vero. La riconosci da parole come "Why does the author mention...". Di solito la funzione del dettaglio si capisce dalla frase che viene prima. I nostri studenti rispondono bene al 55.8% di queste domande: 2 tipi sono più difficili e 7 sono più facili.

Domanda Rhetorical Purpose
[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

Domanda Rhetorical Purpose
Le domande Rhetorical Purpose chiedono perché l'autore ha inserito un dettaglio, un esempio o un'espressione. La risposta non è scritta in modo diretto. Devi collegare il dettaglio all'idea principale del paragrafo. Spesso vedrai parole come: 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

Tipo di domanda TOEFL Reading 4: Vocabulary

Una domanda Vocabulary (lessico) ti chiede il significato di una parola evidenziata, così come il testo la usa. Non devi conoscere già la parola, perché le parole intorno danno quasi sempre un indizio. Per esempio, una spiegazione dopo "or", un contrasto dopo "but" o un esempio nella frase dopo. I nostri studenti rispondono bene al 62.4% delle domande Vocabulary: 5 tipi sono più difficili e 4 sono più facili, quindi gli indizi intorno alla parola funzionano quando li usi.

Domanda Vocabulary
[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.
The word “routine” in the passage is closest in meaning to
  1. automatic
  2. distant
  3. rare
  4. costly

  3. Partnerships can involve repeated encounters.
  4. Client fish always remain with one cleaner for life.

Domanda Negative Factual Information
Riconosci una domanda Negative Factual Information dalla parola NOT o EXCEPT. La risposta corretta è la scelta che il paragrafo non conferma.
  • spellcheck Answer
    Answer: D

    (D) The correct answer is Client fish always remain with one cleaner for life. This question asks for the choice that is NOT mentioned or supported. The passage gives support for Client fish may hold still during cleaning.; Cleaner fish can feed on parasites and dead tissue.; Partnerships can involve repeated encounters., but it does not support "Client fish always remain with one cleaner for life."

Diverse frasi parlano dell'argomento, ma solo una dà l'informazione esatta che la domanda chiede. I nostri studenti rispondono bene al 46.9% di queste domande, il risultato più basso di tutti e dieci i tipi, quindi prenditi il tuo tempo con questo tipo.

Domanda Select in Passage
[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.

Domanda Select in Passage
In una domanda Select in Passage clicchi la frase del testo che risponde alla domanda. La frase corretta deve confermare in modo diretto l'idea richiesta, non solo parlare dello stesso argomento.
  • 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.

Domanda Insert a Sentence
[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]
