Final answer:
To convert "The results should be analysed" into the active voice, identify a subject that will perform the action, leading to "We should analyze the results." Active voice emphasizes the subject's role in performing an action and generally strengthens the clarity of writing.
Step-by-step explanation:
To rewrite the sentence "The results should be analysed" in the active voice, you need to choose a subject that performs the action of analyzing. In active-voice sentences, the subject performs the action of the verb, whereas in passive-voice sentences, the subject is acted upon. The active voice tends to make sentences stronger, clearer, and more concise. An example of rewriting the given sentence in the active voice could be: "We should analyze the results." Here, 'we' acts as the subject that will carry out the action of analyzing.
In scientific and technical writing, it is acceptable to use the passive voice in some parts of a text, particularly in methods and results sections where procedures and data are being reported without personal bias. However, for areas of writing that benefit from a clear and direct style, such as introductions and conclusions, the active voice is generally preferred.
