Why use the passive vice?
1. The der is unknwn: 'Life will be fund.' (We dn't knw wh will find it.)2. The der is unimprtant: 'Statins will be built.' (Fcus n the statins.)3. We want t emphasize the actin/result, nt the persn.4. In science writing, passive vice sunds mre bjective and frmal.

Q: When d we use the passive vice?A: When the der is unknwn, unimprtant, r we want t emphasize the actin/result rather than the persn.In space explratin, we ften use passive vice because: The fcus is n WHAT will happen, nt WHO will d it. "Rckets will be launched." (Nt: "They will launch rckets.")
BIG Questin: "What des it take t explre space?"Passive vice helps us fcus n the achievements:"Satellites will be psitined. Life will be fund. Statins will be built."
