About impersonal passive:

• When a sentence is changed into passive voice, the subject becomes passive/ inactive.
• The object and the action done take importance.
• In impersonal passive voice, the subject must be omitted even if it is present in active voice.
• Instead a dummy will be used to replace the subject in impersonal passive voice. The dummy is "It is said that''. The impersonal sentence will begin with this phrase.
• This will be followed by the action without any change.
• Thus the answers will be as follows:
• 31. It is said that Welders normally prefer a V-shaped weld.
• 32. It is said that the tribal people use tiny bamboo shoots as food.
• 33. It is said that we should reduce the emission of greenhouse gases to save the environment.​
