Develop a
real paragraph.
By Adam Frick · Illustrated draftWhy does a paragraph about species selection discuss street geometry?
The handout below opens with a promise about choosing tree species. The explanation then ranges across canopy, water, street geometry and access. All that material concerns urban heat, but which part actually develops the promised point? I want you to notice the mismatch before admiring the academic vocabulary. A convincing paragraph needs an opening that represents the explanation the reader actually receives.

The pseudo-good version has plausible academic content and a topic sentence. The problem is the mismatch between that opening and the explanation that follows. The stronger version makes the opening represent the actual content, then develops each named condition.
A plausible opening promises the wrong discussion.
Selecting appropriate tree species is an important consideration in the design of urban greening programmes. Residents in densely populated neighbourhoods may have limited access to shaded public spaces, particularly where existing parks are concentrated in areas that are already comparatively well served by environmental amenities and where the routes connecting residential streets to those parks offer little protection from direct sunlight. Municipal planting targets are often expressed as numbers of trees, although the amount of shade provided by individual trees varies considerably with their size and stage of development. Water availability affects transpiration and may create a need for irrigation during prolonged periods of drought. The width and orientation of streets influence the distribution of shade at different times of day, making the location of planting a significant factor in the experience of pedestrians. Public consultation can help planners identify locations that residents consider priorities, but participation requires time and resources that are not equally available across the population. Evaluations conducted shortly after planting may provide an incomplete account of the eventual benefits because young trees have yet to develop substantial canopies. Maintenance budgets must cover watering and the replacement of trees that fail to establish, while assessments of programme success should consider whether residents who face the greatest heat exposure can use the spaces in which investment has occurred.
The opening names the ideas that the paragraph develops.
Urban tree planting can reduce heat exposure, but the effectiveness of planting depends on canopy coverage, water availability, street geometry and equitable access. Canopy coverage influences this effectiveness by determining how much shade trees provide over pedestrian routes and public spaces. Canopy coverage alone cannot establish the cooling benefits of a planting programme. The cooling benefits also depend on water availability, which supports the transpiration that contributes to cooling. Where water availability is limited, maintaining this cooling function may require irrigation during periods of prolonged drought. Alongside these biological constraints, street geometry influences where trees can be planted and how the shade reaches pedestrians. This geometry needs consideration when planners estimate the heat protection offered by additional canopy coverage. Effective heat protection also requires equitable access because cooling public spaces offers limited benefit to residents who cannot readily reach those spaces. Such access should inform planting priorities alongside canopy coverage, water availability and street geometry.
Look past the polished surface.
Check the promise.
Constructed teaching exampleSpecies selection is the promised focus.
The explanation actually covers canopy, water, street geometry and access.
Map the supporting ideas.
Constructed teaching exampleCanopy → Shade · Water → Cooling
Street geometry → Shade placement · Access → Who benefits
Test the ending.
Constructed teaching exampleThe opening identifies conditions for effective heat protection.
The ending brings those conditions back into planting priorities.
Give the paragraph one job worth completing.
A useful paragraph moves an explanation forward. In relation to the point you want to make, choose support that explains, demonstrates or qualifies that point. Then show how the support changes what the reader can reasonably conclude. A shared topic alone does not create a developed argument.
After checking the paragraph’s job, test the opening against the explanation that follows. My topic sentence essay isolates that promise through a shorter worked comparison. Beyond the paragraph itself, the forward and backward referencing essay shows how the ending can prepare a new paragraph and how the next opening can pick up an established point. Through those connections, the reader follows the argument across the blank line.
The paragraph needs development, not padding.
I ask for at least three sentences because I want the writer to develop a point instead of merely announce one. Monash’s guidance allows occasional short paragraphs, so my minimum goes beyond that guidance as a teaching rule. A one-sentence transition may do a perfectly useful job in another kind of writing. In the handout, the important gain comes from matching the opening to the support, not from reaching a magic sentence count.

The Monash guidance on paragraph structure[1] describes the roles of topic sentences, supporting material and an optional concluding link. That guidance supports the need for development while allowing occasional short paragraphs. My three-sentence minimum goes further as a deliberate teaching rule. I want the writer to do the explanatory work before asking the reader to accept the point.
2. Advertising shows the attraction of the shortcut.
Because you’re worth it.Read the original brand page. ↗[2]
The L’Oréal line addresses the reader personally and attaches a purchase to a claim about self-worth. As a clause beginning with “because”, the line leaves the main proposition to the surrounding advertising context. The full stop gives the clause the appearance of a finished statement without supplying that missing proposition. The slogan may serve the brand’s persuasive purpose, but the slogan alone offers no developed explanation of a product’s value.

The Apple headings repeat a comparative structure and give each adjective phrase a full stop. The wording invites the reader to expect improvement without making either phrase a complete sentence. The extract alone supplies no explanation of what has become more delightful or how durability has improved. Apple provides supporting information elsewhere on the page, so my criticism concerns the headline technique rather than an absence of product information. In an explanatory paragraph, I want the writing to name the improvement and develop the reason the improvement matters.
