TOEFL Reading Explained: 2026 Format & Task Types
TOEFL Reading at a Glance
The Three Reading Task Types
1. Complete the Words
You read a short academic paragraph in which some words are only partly written. Your job is to type the missing letters and finish each word. To find the right word, you rely on your vocabulary and on the grammar and meaning of the sentence around each blank.
Complete the Words
Fill in the missing letters in the paragraph.
Archaeologists often study the distribution of ancient pottery to map forgotten trade routes. By examining the broken , experts trace where domestic . When matching artifacts appear in geographic regions, historians understand that complex linked those populations. Such widespread exchanges suggest that early societies were highly interdependent rather than entirely isolated. Consequently, a simple clay jar provides crucial evidence about historical economic relationships and cultural interactions.

Look at the archaeology passage above. Most blanks sit where the sentence needs a noun, a verb, or an adjective. A blank right after a or the is usually a noun, a blank right after the subject is usually a verb, and a blank in front of a noun is often an adjective. Use the letters you can see to narrow your choices to two or three words. Then choose the one that fits the meaning of the sentence.
Paragraphs often repeat an idea, so a word you have already read can be the answer one sentence later. Check the spelling once more before you move on, because a single wrong letter can cost you the point.
2. Read in Daily Life
Not every reading task comes from a textbook. Here you read short everyday texts such as a notice, an email, a menu, or a social media post, and each text usually comes with two or three questions.

- Update regarding your washing machine repair
Dear Mr. Henderson, our technician completed the initial inspection of your washing machine this morning. While the motor is now functioning properly, a leak was discovered in the drainage hose during the final testing phase. We must order a specific replacement seal before we can successfully finalize the repair. Please contact our office to schedule a brief follow-up visit once the part arrives this Wednesday.
Q1What is the main purpose of the email?
Correct.
Not quite. The answer is (B).
The email informs the customer that a leak was found and that a follow-up visit is needed ("Please contact our office to schedule a brief follow-up visit") because the repair is not yet finished.
Q2According to the email, why is the company unable to finish the repair immediately?
Correct.
Not quite. The answer is (C).
The email states, "We must order a specific replacement seal before we can successfully finalize the repair," which indicates that the part is not currently on hand.
Choose an answer for each question, then select See answers.
As in the email above, a purpose question often comes with a question about one specific detail. Look for the purpose in the opening line and the final request, and for details in the sentence that contains the key words of the question. Some daily-life questions also ask what the writer suggests without saying it directly.
3. Read an Academic Passage
This task is closest to what many students expect from the TOEFL. You read a passage similar to something from a university course, on a subject such as biology or history. By university standards it is short, usually around 200 words.
Most questions focus on the main idea and supporting details. Others ask about the meaning of an important word or how one idea connects to another.

Vibrational Signaling in Treehoppers
Many small insects communicate not by sound carried through the air but by vibrations sent through the surfaces they stand on. Treehoppers, a group of plant-feeding insects related to cicadas, rely almost entirely on this kind of substrate-borne signaling. Each species produces a distinctive pattern of pulses by rocking its abdomen, and these vibrations travel along stems and leaves to nearby companions.
The mechanism depends on the host plant rather than on the insect alone. When a male treehopper rocks its body, the muscle contractions push tiny pulses into the stem, which then conducts the signal much like a tuning fork transferring sound through wood. Females walking on the same shrub feel these arriving waves through specialized leg sensors and can identify a suitable mate without ever seeing him. In one well-studied species, Umbonia crassicornis, the male's call elicits a precisely timed female response that allows the pair to locate each other on a dense bush within seconds.
Yet this private channel comes with constraints. Vibrations weaken sharply across thicker stems and barely cross from one plant to the next, which sets a hard ceiling on signaling range. Some predatory insects, including assassin bugs, have evolved sensitivity to the same frequencies and use overheard treehopper calls to find their prey. Stiff or wilted host plants distort the original pulse pattern, garbling the message and sometimes leading females to ignore otherwise compatible males.
1 / 5
Q1How do treehoppers transmit their communication signals to nearby companions?
Correct.
Not quite. The answer is (B).
Paragraph 1 introduces "substrate-borne signaling" via "rocking its abdomen," and paragraph 2 explains how the muscle contractions push pulses into the stem; B paraphrases both. A invents an airborne-sound mechanism the passage explicitly contrasts away from. C borrows the assassin-bug detail from paragraph 3 and recasts it as the signaling channel itself. D treats the rocking motion as a visual display, which the passage never claims.
Q2The word "elicits" in paragraph 2 is closest in meaning to
Correct.
Not quite. The answer is (A).
The male's call "elicits a precisely timed female response," meaning it causes or evokes the response. "Draws out" matches that sense. "Interrupts" inverts the relationship, "amplifies" wrongly suggests sound enhancement, and "precedes" captures only sequencing without the causal pull.
Q3How does a female treehopper identify a suitable mate on the same plant?
Correct.
Not quite. The answer is (C).
Paragraph 2 states females "feel these arriving waves through specialized leg sensors and can identify a suitable mate without ever seeing him"; C paraphrases this directly. A reverses the role of vision, since the passage explicitly says identification occurs without sight. B invents a mutual-approach protocol that is not described. D borrows assassin bugs from paragraph 3 and falsely casts their signals as the cue females respond to.
Q4What can be inferred about treehoppers attempting to communicate on a wilted host plant?
Correct.
Not quite. The answer is (A).
Paragraph 3 states wilted plants "distort the original pulse pattern, garbling the message and sometimes leading females to ignore otherwise compatible males," which supports the inference in A. B contradicts the passage, which says vibrations weaken across thick or unsuitable stems. C invents a switch to airborne sound; the passage frames vibrations as the only channel. D speculates about predator detection, which the passage does not tie to plant condition.
Q5Look at the four letters (A, B, C, and D) in the passage that indicate where the following sentence could be added. Where would the sentence best fit?
Each pattern travels with little distortion along a fresh, rigid stem.
You can also select a letter in the passage.
Correct.
Not quite. The answer is (B).
Slot B sits between the tuning-fork mechanism description and the sentence about female detection. The left context establishes that the stem conducts the pulses "much like a tuning fork transferring sound through wood," and the inserted sentence supplies the missing link -- that the pattern arrives intact on a healthy stem -- which then justifies the next claim that females can identify a mate from those waves. Slot A breaks the flow before the mechanism has been described, so "Each pattern" lacks a referent. Slot C interrupts the move from general detection to the Umbonia example. Slot D ends the paragraph on a generic transmission claim that pre-empts the limitations introduced in paragraph 3.

How Adaptive Reading Works
The Reading section has two stages. Everyone begins with the same first stage of about 18 to 21 minutes. Based on how you perform there, the test sends you to a second stage of about 9 minutes that is either easier or more challenging.
The test does not change difficulty after every question. It adjusts once, between the two stages. In official ETS documents, the first stage is called the router and the second stage is the lower or upper module.
Once you move on to the second stage, you can't go back to the first. Your score also takes into account the difficulty of the questions you answered, so students who get different second stages are scored fairly.
Two Common Misconceptions
"I need background knowledge about the academic topic." You don't. ETS states that all the information you need is in the text, and no prior knowledge of the topic is required. The text also stays on screen while you answer, so you can always check it again.
"Shorter texts mean an easier test." The texts are shorter, but the difficulty range is wide, running from beginner level up to the most advanced level. A strong first stage leads to harder questions in the second stage. With short texts, each sentence is important, so careful reading matters more than reading speed.
