Parse the instruction
Distinguish words-only instructions from words-and/or-a-number instructions.
IELTS Academic Reading · Skill lesson
Parse the instruction, predict the missing grammar, locate the exact passage span and remove every unnecessary word before submitting.
Short answer: Treat the word limit as part of the question. A factually correct phrase still loses the mark if it exceeds the stated maximum or fails to complete the sentence grammatically.
What this skill changes
A useful reading skill changes what you notice, what you ignore and how you prove an answer.
Distinguish words-only instructions from words-and/or-a-number instructions.
Use the words before and after the gap to decide whether you need a noun, phrase, number or modifier.
Take the shortest exact span that preserves meaning and completes the sentence naturally.
WeLearn method
Follow these steps until the sequence becomes automatic under time pressure.
Record the allowed number of words before looking for an answer.
Combine the frame before and after the blank to predict grammar and meaning.
Find the matching passage sentence and select only the required words.
Read the completed sentence aloud, remove duplication and count the final response.
Worked contrast
Frame: ‘during ___’; passage: ‘during long summer afternoons’; answer: ‘long summer afternoons’ under a two-word limit.
Answer ‘summer afternoons’: it keeps the required time meaning, fits after during and stays within two words.
Guided practice
Make a decision first. Then use the explanation to compare your reasoning with the evidence.
Read the instruction, predict the grammar and copy only the missing passage words.
Passage
A city does not heat evenly. Dark roofs, roads and other developed surfaces absorb and hold more solar energy than many rural surfaces. Buildings can also slow the release of heat after sunset. The result is a temperature difference both between city and countryside and between neighbourhoods inside the same city.
Trees and other vegetation cool streets in two connected ways. Their leaves shade walls and pavements, so those surfaces receive less direct sunlight. Plants also release water through evapotranspiration, a process that uses heat from the surrounding air. The benefit therefore comes from both shade and evaporation, not from greenery as decoration.
Where planting space is scarce, a building owner can change the roof surface. A cool roof reflects more sunlight and releases absorbed heat more effectively than a conventional roof. This can reduce roof and indoor temperatures without rebuilding the entire property, although the result depends on climate, insulation and roof design.
Before spending money, planners need to know where heat exposure and missing shade overlap. A canopy survey can show which streets lack trees, while surface and building data reveal where a roof programme may have the greatest effect. A citywide average is less useful than a map that identifies blocks with different needs.
No single measure fits every block. Young trees need water and long-term care; green roofs can cost more to install; reflective roofs work differently across climates and building types. A practical heat plan therefore combines methods according to local space, budget and maintenance capacity, then checks whether the intended neighbourhoods actually benefit.
Evidence: “Buildings can also slow the release of heat after sunset.”
Evidence: “Their leaves shade walls and pavements”
Evidence: “releases absorbed heat more effectively than a conventional roof”

Passage
Mangrove decline was already a concern in parts of Puerto Rico, but consecutive hurricanes made the risk impossible to ignore. Damaged forests left coastal communities with less natural protection and weakened habitat. The storms did not create every problem; they transformed a gradual loss into an urgent restoration programme.
A healthy mangrove forest does more than occupy the shoreline. Dense roots interrupt moving water and reduce wave energy, while branches and leaves help break the force of wind. The forest is therefore a flexible natural barrier that can lessen erosion, flooding and storm damage for areas behind it.
Planting seedlings is not always the first useful step. Roads, debris or altered channels may prevent tides from reaching damaged ground in the right pattern. Restoration teams can begin by reopening water routes and improving site conditions. New trees then have a better chance to establish rather than being placed into a system that still cannot support them.
The project also depends on people who live near the restoration area. Local labourers and volunteers can clear channels, plant trees and monitor recovery. When young participants receive training and paid experience, environmental work becomes a route into employment as well as a way to rebuild the coast.
Storm protection is only one reason to recover a mangrove forest. The habitat can support fish and birds, store coastal carbon and contribute to recreation and tourism. Evaluation should therefore examine ecological and community outcomes over time, rather than treating the shoreline as a single-purpose defence structure.

Two focused drills lead into four full passage sets. Drafts, time, scores and error patterns stay on this device.
Copy only the words missing from the frame; do not repeat articles, connectors or modifiers already supplied.
Passage extract
Sleep looks passive from the outside, yet the sleeping brain remains busy. It cycles through different states and continues to process information gathered while a person was awake. Researchers therefore treat sleep as part of learning itself, not simply as an empty interval between two periods of study.
Passage extract
A large volunteer group is useful only if observations can be compared. Projects therefore provide instructions, examples and fixed reporting categories. Researchers may repeat checks, compare several classifications or flag unusual entries for review. The shared method reduces variation without pretending that every observation will be perfect.
Passage extract
Tests sometimes show that too few seeds in a sample will still grow. Curators then plant part of the remaining stock under controlled conditions and collect a fresh generation of seed. This regeneration must be managed carefully so that the renewed sample continues to represent the original material.

Even when the tracks connect, the sales journey may not. A trip involving several operators can be difficult to compare or buy as one itinerary, and separate tickets may complicate information and passenger protection when disruption occurs. Better booking connections are therefore part of the rail project, not a minor addition after trains begin to run.

Review and sources
This material was reviewed in August 2026 to keep the official IELTS Reading format separate from the WeLearn learning strategy used on this page.
Official IELTS Academic Reading format: Used to verify that task instructions and word limits are binding.
WeLearn original practice sets: Used to train minimal grammatical answers without reproducing official questions.
Scope: these WeLearn exercises support academic-reading practice. They are not official IELTS questions and do not predict a band score by themselves.
