中考網(wǎng)整理了關(guān)于2021年中考英語復(fù)習(xí)之主動(dòng)語態(tài)改被動(dòng)語態(tài)的方法，希望對(duì)同學(xué)們有所幫助，僅供參考。
主動(dòng)語態(tài)改被動(dòng)語態(tài)的方法
1）將主動(dòng)語態(tài)改為被動(dòng)語態(tài)應(yīng)注意以下三個(gè)方面：①將主動(dòng)語態(tài)的賓語改為被動(dòng)語態(tài)的主語；②將主動(dòng)語態(tài)的謂語動(dòng)詞改為“be＋過去分詞”結(jié)構(gòu)；③將主動(dòng)語態(tài)的主語改為介詞by之后的賓語，放在謂語動(dòng)詞之后（有時(shí)可省略）。
2）含直接賓語和間接賓語的主動(dòng)語態(tài)改為被動(dòng)語態(tài)時(shí)有兩種情況：①把間接賓語改為被動(dòng)語態(tài)的主語，直接賓語仍保留原位；②把直接賓語改為主動(dòng)語態(tài)的主語，此時(shí)，間接賓語前要加介詞to或 for。如：
He gave the boy an apple．→ The boy was given an apple．（或An apple was given to the boy．）
Her father bought her a present．→ She was bought a present by her father．（或A present was bought for her by her father．）
3）不帶to的動(dòng)詞不定式作賓語補(bǔ)足語的主動(dòng)語態(tài)，改為被動(dòng)語態(tài)時(shí)不定式前要加to。如：
They watched the children sing that morning．→ The children were watched to sing that morning．
4）帶復(fù)合賓語的動(dòng)詞在改為被動(dòng)語態(tài)時(shí)，一般把主動(dòng)語態(tài)的賓語改為主語，賓語補(bǔ)足語在被動(dòng)語態(tài)中作主語補(bǔ)足語。如：
We call him Xiao Wang．→ He is called Xiao Wang．
He cut his hair short．→ His hair was cut short．
They told him to help me．→ He was told to help me．
5）短語動(dòng)詞是不可分割的整體，改為被動(dòng)語態(tài)時(shí)要保持其完整性，介詞或副詞不可遺漏。如：
We must take good care of the young trees．→The young trees must be taken good care of．
6）含有賓語從句的主動(dòng)結(jié)構(gòu)變?yōu)楸粍?dòng)結(jié)構(gòu)時(shí)，通常用it作為被動(dòng)結(jié)構(gòu)的先行主語，從句放在句子后面；也可采用另一種形式。可以這樣轉(zhuǎn)換為被動(dòng)結(jié)構(gòu)的動(dòng)詞有know，say，believe，find，think，report等。如：
People believe that he is ill．→It is believed that he is ill．（或：He is believed to be ill．）
