Professional English does not require long sentences. A reader needs to understand the action, the person or system responsible and the time relationship between events.
Build a complete core sentence
Start with a subject and a verb, then add the object or result when needed. In “The worker retries the job,” the reader can identify the actor and action immediately. Sentence fragments may work as labels, but an explanation usually needs a complete thought. Check whether every added clause makes that thought easier to understand.
Choose a tense that matches the meaning
Use a tense that accurately describes the situation. A past project, a current responsibility and a general technical rule have different time meanings. You do not need to force every sentence into the same tense if the events occur at different times. Make changes in time deliberate and support them with clear context.
Replace vague references with specific nouns
Words such as it, this and they become unclear when several possible references appear nearby. “This reduced errors” is weaker when the previous paragraph describes three changes. Name the change and the measured result if you actually have evidence. Prefer a precise explanation over impressive vocabulary that leaves the meaning uncertain.
Worked example
Compare “It was done and then they checked it” with “I added a validation rule, and a teammate reviewed the change.” The second sentence gives the reader concrete actions and responsibility. It does not invent an outcome or claim that the review proved the software perfect.
Check your understanding
Try each question before opening its explanation. These are free practice prompts; they do not use game chances.
Must every sentence use active voice?
No. Passive voice can be useful when the actor is unknown or unimportant. Use it deliberately; avoid hiding responsibility when knowing who acted helps the reader understand the event.
Why can “this fixed it” be unclear?
The reader may not know which change or which problem you mean. Replace one or both references with the specific change and observed result.
Rewrite “The app have errors yesterday.”
A clear version is “The app had errors yesterday.” If you know the cause or scope, add that information separately rather than packing an uncertain explanation into the correction.
