Precision: Choose words that accurately describe the degree of change (e.g., “sharp rise” for a significant increase, “slight increase” for a minor one).
Diversify your vocabulary: Avoid repeating words like “increase” or “decrease” too often. Use synonyms or alternatives such as “surge,” “decline,” “plummet,” “grow steadily,” etc.
Grammar accuracy:
- Use the past simple for charts describing past data.
- Use the present simple for static processes.
Select key information: You don’t need to list every single data point; focus on major trends or significant changes.
Combine vocabulary with complex structures:

Example: “While the number of international tourists increased sharply, domestic tourism showed a steady decline.”

Avoid overuse: While linking words are important, using too many will make your writing sound cluttered and unnatural.
