Expert writing Tips
Best practice
When using "has been fast", ensure the context clearly indicates what is being described as fast, providing specific details or examples to support the claim. For instance, instead of saying "Adoption has been fast", specify, "Adoption of the new software has been fast, with a 50% increase in user registrations this quarter."
Common error
Avoid using "has been fast" in isolation without providing context or supporting information. Without specific details, the statement can be vague and lack impact. For instance, saying "Growth has been fast" is less effective than saying "Growth in the renewable energy sector has been fast, driven by increasing consumer demand and government incentives."
