IELTS Academic Reading · Question-type lesson
Use column categories and row relationships to predict the missing information, then confirm a precise passage span within the word limit.
Short answer: Categorised comparison. Start from row label + column heading + passage detail, and control the main risk: reading the blank without its table context.

WeLearn method
Follow these steps until the sequence becomes automatic under time pressure.
Confirm whether answers come from the passage and record the limit.
Use row labels and column headings to define the missing category.
Find where the passage discusses that row or category.
Check meaning, grammar and word count in the complete row.
Worked contrast
Choose a nearby phrase because it appears in the same paragraph.
The row is “Design factor” and the column is “What to study”, so select the passage phrase that names the exact factor and fits the cell grammar.
Guided practice
Make a decision first. Then use the explanation to compare your reasoning with the evidence.
Reading passage
Public buildings in warm regions are increasingly being designed to reduce the need for mechanical air conditioning. Architects call these methods passive cooling because they lower indoor temperatures without relying mainly on powered machines. The approach is not new: older houses in many climates used courtyards, thick walls and shaded openings long before electric cooling became common.
One method is cross-ventilation. When windows or vents are placed on opposite sides of a room, moving air can carry heat away from occupants and surfaces. This works best when designers study the direction of prevailing winds before deciding where openings should go. If the openings face the wrong direction, the room may still feel still and humid.
Another method is thermal mass. Materials such as stone, concrete and brick can absorb heat during the day and release it slowly at night. In schools and libraries, this can make indoor temperatures more stable, especially where nights are cooler than afternoons. However, thermal mass is less useful if the building cannot release stored heat after sunset.
Shading is also important. Deep roof edges, external screens and trees can block direct sunlight before it reaches windows. External shade is usually more effective than curtains because it stops heat before it enters the glass. The best shading design depends on the sun's angle, which changes with season and time of day.
Passive cooling is not a complete replacement for all mechanical systems. Hospitals, laboratories and data rooms may still need precise temperature control. But in many public buildings, passive methods can reduce energy demand and make indoor spaces more comfortable during ordinary use.

Reading passage
Rain gardens are shallow planted areas designed to collect water after heavy rainfall. Instead of sending all runoff into drains at once, the garden holds water temporarily and lets it soak slowly into the soil. Schools are starting to install them because playgrounds and car parks often create large amounts of surface water during storms.
The first design decision is location. A rain garden should sit below the area it drains, but it must not be placed where water already remains for days. If the soil is permanently wet, plant roots may rot and the garden will not absorb new water effectively. Designers also keep rain gardens away from building foundations so that water does not increase damp problems.
Plant choice matters as much as shape. Deep-rooted native plants are often recommended because they tolerate both wet and dry periods and help open channels in the soil. Decorative annual flowers may look attractive, but they usually need more maintenance and may not survive sudden flooding.
Schools often use rain gardens as outdoor classrooms. Students can measure rainfall, observe insects and compare how quickly different surfaces dry after a storm. Maintenance remains important: leaves must be cleared from inlet points, and litter should be removed before it blocks the flow of water. A well-managed rain garden reduces runoff while making drainage visible to students.

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: Confirms completion tasks using words from the text or a supplied list and that any stated word limit is binding.
WeLearn practice blueprint: Defines coordinate-led search, held-back transfer, local persistence and the client-key security boundary.
Scope: these WeLearn exercises support academic-reading practice. They are not official IELTS questions and do not predict a band score by themselves.

Es un tipo oficial de IELTS Reading donde completas espacios en una tabla usando informacion del pasaje. La tabla organiza datos por filas y columnas, y las respuestas deben respetar el limite de palabras.
Note Completion organiza apuntes por encabezados o bullets. Table Completion exige comparar categorias en columnas y filas, por eso debes usar la estructura de la tabla para saber que tipo de dato falta.
Lee los titulos de columnas y filas antes del pasaje. Eso te dice si buscas material, fecha, funcion, causa, resultado o problema. Luego escanea la zona relevante y copia palabras exactas.
