7、 watch in two days.This watch can be repaired in two days.They should do it at once.It should be done at once.五、被動語態(tài)的用法（1）不知道或沒有必要說明動作的執(zhí)行者是誰。例如：Some new computers were stolen last night.一些新電腦在昨晚被盜了。（不知道電腦是誰偷的）This bridge was founded in 1981.這座橋竣工于1981年。（2）強調(diào)動作的承受者，而不強調(diào)動作的執(zhí)行者。例如：The glass was broken
