我們的價格是經(jīng)過精密核算的。(譯為判斷句）

By early 1997, 19 out of 71 cases had been settled“out of court" , without going through the full panel process.

到1997年初為止,71個案子中已有19個通過“庭外和解”得以解決，沒有經(jīng)過全部的小組裁決過程。（譯為主動句）

通過以上例句我們可以看到，有些句子或是無從說出動作發(fā)出者，或是為了突出談話的中心，或是不知道或沒有必要說出動作執(zhí)行者足誰等情況。在英語中還有一些固定的被動結(jié)構(gòu)，譯為漢語時已成定式，例如：

It is stipulated that ...按照規(guī)定......

It is felt that...人們感到……

It has been proved that …業(yè)已證明……

It should he noted that...應當指出……

It is said that...                據(jù)說……

It is well-known that…眾所周知……

It is believed that...                人們認為……

It is expected that...                  人們希望……

It is reported that...               據(jù)報告……
