am/is/are+done例如：Childrenlovethesesongs.(主動(dòng)語態(tài)）Thesesongsareloved

bychildren.(被動(dòng)語態(tài)）4.被動(dòng)語態(tài)的用法：(1)要表達(dá)“被……”、“受……”、“遭……”、“讓……”之類的語義。如：Teachersarewellrespected.(2)強(qiáng)調(diào)動(dòng)作接受者。例如：Heisknownfarandwide.(3)不知道或沒有必要指出動(dòng)作的執(zhí)行者。如：Theroomiscleanedeveryday.Myfatherwatertheflowerseveryday.Wesweeptheflooreveryday.Theyplantthetreeseveryyear.HeplaysthecomputergamesonSaturdays.5.Shesendsanemailonceaweek.寫出下列句子的被動(dòng)語態(tài)。Arecorder
