一般過去時(shí)的被動(dòng)語態(tài)
Liu was encouraged at first to train for the high jump.
Liu Xiang’s ability in hurdling was noticed by Sun Haiping.
我們知道，被動(dòng)語態(tài)的動(dòng)詞形式為“be+動(dòng)詞的過去分詞”，其中be為助動(dòng)詞，根據(jù)不同的人稱和時(shí)態(tài)有形式的變化。因此，一般過去時(shí)的被動(dòng)語態(tài)肯定句的結(jié)構(gòu)為：
主語+was/were+動(dòng)詞過去分詞（+by+動(dòng)作執(zhí)行者）
一般過去時(shí)被動(dòng)語態(tài)的各類句式與一般現(xiàn)在時(shí)被動(dòng)語態(tài)的各類句式類似，你可以嘗試總結(jié)嗎？
否定句：主語+was/were+not+動(dòng)詞的過去分詞（+by+動(dòng)作執(zhí)行者）
e.g.The window was not broken by Tom.
一般疑問句：Was/Were+主語+動(dòng)詞的過去分詞（+by+動(dòng)作執(zhí)行者）
e.g. Was the room cleaned by Tom?
特殊疑問句：特殊疑問詞+was/were+主語+動(dòng)詞的過去分詞（+by+動(dòng)作執(zhí)行者）
e.g. When was the book published?
前面我們總結(jié)了一般過去時(shí)被動(dòng)語態(tài)的各類句式，那么encourage sb. to do sth, allow sb. to do sth.等不定式作賓語補(bǔ)足語的結(jié)構(gòu)在被動(dòng)語態(tài)中如何處理呢？我們來對(duì)比一下其主動(dòng)語態(tài)與被動(dòng)語態(tài)的形式：
The school encouraged Liu Xiang to train for the high jump.
Liu Xiang was encouraged (by the school) to train for the high jump.
可以看出，被動(dòng)語態(tài)的句子是把主動(dòng)語態(tài)中的賓語提到了主語的位置，賓語補(bǔ)足語的位置不變。應(yīng)該注意，這樣的句子往往不會(huì)提到動(dòng)作的執(zhí)行者。這正是被動(dòng)語態(tài)的特點(diǎn)：被動(dòng)語態(tài)強(qiáng)調(diào)動(dòng)作承受者，而不強(qiáng)調(diào)動(dòng)作執(zhí)行者。
