1. 主动语态即主语为动作的执行者；被 动语态即主语为动作的承受者。现在完 成时的被动语态同它的主动语态一样， 强调过去的动作对现在造成的影响或结 果，但主语为动作的承受者，表示
8 _t_o_ta_l_ly__ completely
9 _a_n_y_h_o_w__ anyway
10 _fi_n_a_n_c_e_ activity of managing money
plete the passage with the words below.
artificial technology intelligent applications explore Web reality logically
4. 一些特殊动词, 如borrow, finish, begin, buy, start, return, marry, open, join等构 成的现在完成时的被动语态不能与表示 一段时间的状语连用。若要表达相应的 意思， 则需改换动词或时态。如： My brother has had (不能用has bought) this bike for almost four years. How long has this book been bought? How long ago was this book bought?
believed. [正] Such a man has hardly been
believed.
2. 并不是所有动词都有被动语态 (1) happen, take place, break out, belong
to, cost, last等不及物动词或词组无被 动语态。如： [误] Great changes have been taken
(4) 双宾语动词变被动语态可将其中的一 个宾语变为主语， 另一个保留不动。 主动：I have given him the key. 被动：He has been given the key. 被动：The key has been given (to) him.
(5) 带复合宾语的动词变被动语态时, 只 能将宾语变为主语, 原来的宾补保留不动， 改称主语补足语。 主动：I have asked her to help you. 被动：She has been asked to help you.
主动语态变被动语态的方法
(1) 把主动语态的宾语变为被动语态的主 语。
(2) 把谓语变成被动结构 (be＋过去分词) (根据被动语态句子里的主语的人称和 数，以及原来主动语态句子中动词的 时态来决定be的形式)。
(3) 把主动语态中的主语放在介词by之 后作宾语, 将主格改为宾格。
All the people laughed at him. He was laughed at by all the people. They make the bikes in the factory. The bikes are made by them in the factory.

thinking, working, etc

the lake. Some trees have been planted around the lake. 2. My father has locked the door. The door has been locked. 3. Someone has turned off the light.
have / has + not + been + done Tom’s novel has not been published. 汤姆的小说还没有被出版。

注意:
