As we can see in the pairs f sentences，the bject（主语） in an active sentence becmes the subject（宾语） in a passive sentence. Bth sentence types cnvey a similar meaning，but they are slightly different. Fr example，in an active sentence，the subject is ding an actin t an bject，while in a passive sentence，the subject is having smething dne t it，and the der f that actin is nt necessarily mentined. Active sentences are used ften，as they are mre direct. Passive sentences are ften used when the der f an actin is unknwn，nt imprtant，r preferred nt named.
Read the pem. Then think f yur wn situatin and write a similar pem.
