14、 freely Important and difficult points: The usages of The Present Perfect Passive Voice The Present Perfect Passive Voice 现在完成时被动语态由”has/have + been + 及物动词的过去分词”构成。使用现在完成时 被动语态要注意以下几点： 1. 只带有一个宾语的动词变为被动语态时，将主动语态的宾语变为被动语态的主 语。例如： We have built many houses in the past ten years. Many houses have been
15、built in the past ten years. 2. 带有双宾语的动词，如 give, send, bring, take, teach, show, tell, make, sing, write, read, sell, buy, tell, pay, lend, pass, promise 等，变为被动语态时，可将其中一个宾语变为 主语，另一个保留不动。例如： We have given him the book. He has been given the book. The book has been given to him. 3. 带有复合宾语的动词变为被动语态时，只能
16、将宾语变为主语，原来的宾补改为 主语补足语。原来省略 to 的不定式作宾补的，被动语态中要用带 to 的不定式。例如： I have told them to help you.They have been told to help you. I have made her work hard.She has been made to work hard. 4. 短语动词变为被动语态时，要注意保持短语的完整性，动词后原有的介词或副 词不可遗漏。例如： They have referred to the books.The books have been referred to (by them

19、ll the preparations for the task _, and we are ready to start.(NMET2000 春招) A. completed B. complete C. had been completed D. have been completed 解析本句的意思是：这项工作的一切准备工作已经就绪,我们只等开始了。前半句主 语和谓语有被动关系，后半句暗示说话是从现在着眼，所以用现在完成时态的被动语 态。答案 D。 练习: 单项填空 1.
