E.g.: A lot of fresh water is wasted . Many natural resources are consumed intensively. Du verwendest das Passiv, wenn die Aktion/Tätigkeit wichtiger ist als die Person, die diese ausführt. This is how it works: The object of an active sentence becomes the subject of the passive sentence. Wenn wir das Passiv verwenden, wird das Objekt im aktiven Satz zum Subjekt im passiven Satz. Active: We waste a lot of fresh water . Passive: A lot of fresh water is wasted. Here it is not important WHO wastes it. Sometimes it can be important. Look at this sentence: Active: Jack wastes a lot of fresh water. Passive: A lot of fresh water is wasted by Jack . This can mean e.g. not by his sister. In this case you add this information with by . We form the passive by putting the verb “to be ” into whatever tense we need and then adding the past participle (= last form of the verb). Das Passiv wird mit der jeweiligen Form von „to be“ gebildet. D. h. du musst auf die Zeitform achten und zusätzlich das „past participle“ verwenden. Form: tense and form of be + past participle (= last form of the verb) (+ by with further information) The condition of our planet Air travel The issue of climate change Too much food Some places A new railroad line has been affected mainly must be reduced . was spread all over the world is wrapped in plastic. will be visited more often in the future. is going to be planned for next year. by our food choices. by Greta Thunberg.
