A more effective approach to convince others is to support the broad general statements with details. Students can begin by writing two to three sentences to support the stated generalization. Two more techniques can be introduced sometime during this stage for more effective writing. Choose some example sentences from the students' composition and ask them to discuss and suggest corrections. Use active verbs whenever possible.
Active verbs makes the sentence stronger and gives force to the writing.
On the other hand, passive voice constructions are less direct, less natural and less vigorous. Use the passive voice only when it is needed. Technical content in an English manuscript should be communicated in a simple and direct manner so that the readers can reach the author's intended meaning quickly. Use simple, direct and concrete words whenever possible. Avoid pompous words and words loaded with positive or negative emotions.
