表示对现在或将来的被动动作,如“The work must be finished by tomorrow.”(这项工作必须在明天之前完成)。

时态错误问题
错误示例
The house has been built last year.
纠正方法
将has been built改为was built ,即The house was built last
year.
04
改错
The book sells well.(去掉is selling ,改为一般现在时)
06
改错
The house has been being built for two years.(将is being built改为has been being built,表示持续进行的动作)
答案及解析
一般过去时表示过去某一时间发生的动作。 • 去掉is selling,改为一般现在时。因为sell可用作及物动词,也可用作不及物动词。用作及物动词时表示卖的
具体动作,其主语是人;用作不及物动词时表示主语的特征或状态,其主语通常是物。此处表达的是书的特点 ,应该用一般现在时的主动语态。 • 将is being built改为has been being built。因为时间状语now for two years表示到目前为止已经持续了两 年的动作,所以应该用现在完成进行时的被动语态。

误用与避免方法探讨
常见误用类型分析
主谓不一致
在被动语态中,主语通常是动作的承受者,谓语应与主语保持一致。然而,有时会出现主 谓不一致的错误,如“The book was wrote by him.”(正确形式应为“The book was written by him.”)
如果不定式前面的名词是对句子的主语的特点进行的说明的时候,使用不定式的主 动语态表示被动含义。
在there be句型中,当动词不定式修饰名词作定语时,不定式用主动式作定语,重 点在人。
动名词作主语或宾语补足语时
动名词作主语时,谓语动词为单数,在动名词和不定式中,作为介词的宾语是动 名词,动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻 辑主语。

结构上的错误
总结词
结构上的错误是指句子中的结构不完整或结 构混乱,导致句子意义不清或语法错误。
详细描述
结构上的错误通常是由于句子中的结构不完 整或结构混乱所导致的。例如,“The book was written by him and published in 2019”这句话中,“and”连接了两个 并列的谓语动词“written”和 “published”,但是“and”前没有主语, 因此这个句子存在结构上的错误。
例如,在句子"The book was written by him."中,"was written"是被动语 态的形式,表示"书"是动作"写"的接 受者。
被动语态的分类
根据时态和语态的不同,被动语态可 以分为多种形式。
此外,还有被动语态的虚拟语气形式 等。
例如,现在进行时的被动语态形式为 "am/is/are being done",过去完成 时的被动语态形式为"had been done"。

一、主动语态和被动语态
动词的语态表示的是主语和谓语之间的关系。 英语的语态分主动语态和被动语态。 主动语态(Active Voice)表示主语是动作的执行者。 被动语态(Passive Voice)则表示主语是动作的承 受者。只有及物动词才有被动语态。
The construction of the new lab must be completed by the end of next month.
4、科技文章、新闻报道、书刊介绍等媒体中, 突出描述的客观性。如:
Over 13 people have been killed in this accident so far.
Calculator can't be used in the maths exam. Books and newspapers in the reading room mustn't be taken away.
3. 为了使语气委婉,避免提及自己或对方而使用 被动语态,或由于修饰的需要,使用被动语态, 使句子得以更好的安排。如:
3.一般将来时
地铁将在明年完成。
The subway w__il_l_b_e__f_in_i_s_h_e_d_ next year.
1. 河上将建一座桥。 2. 如果你违反法律,你就会受到惩罚。
1. A bridge _w_i_ll__b_e__b_u_i_lt_ over the river. 2. If you break the law, you _w_i_ll_b_e__p_u_n_i_sh_e_d.
-al….的------------physical (形容词) -en变得------------ widen(动词) -ful充满-----------spoonful(形容词)
Mis- -ful--------------mistrustful不信任的 Un- -able-------------unbearable不能容忍的
一般现在时 Simple Present
1. 他经常嘲笑我。 2. 我经常被他嘲笑。
1. He often laughs at me. 2. I a_m__ often _l_a_u_g_h_e_d_a_t__by him.
2.一般过去时 Simple Past
1. 警察抓到一个小偷。 2. 一个小偷被警察抓到了。
1. The police caught a thief. 2. A thief _w__a_s _c_a_u_g_h_t_ by the police.
2.一般过去时 Simple past
1. 狗咬了他。 2. 他被狗咬了。 1. A dog bit him. 2. He w__a_s_b_i_tt_e_n_by a dog.

三、使用被动语态时应注意的几个问题
1. 含有情态动词的被动语态: 动词原形变成be+done
情态动词+do
情态动词+be+过去分词
be going to do be to do be sure to do used to do have to do had better do
be going to be done be to be done be sure to be done used to be done have to be done had better be done
5.现在进行时的被动语态
1. A stranger is following the girl.
The girl __i_s__b_e_in_g___fo_l_l_owbeyda stranger.
二、何时使用被动语态
1. 动作谁做的不知道,说出谁做的没必要。 如:
Paper is made from wood. The house was built in 1950. He was wounded in the fight. 2. 需要强调动作承受者。 如:
Everybody likes him. He is liked by everybody. (动作接受者+be+done +by +动作发出者)
(二) 各种时态下的被动语态
结构:be+过去分词
时态变化主要体现在be的变化上,以 do 为例,列表如下:
一般现在时:
am / is 在完成时 Present Perfect
1. BP机已经被手机所取代。 2. 这件事已经被遗忘了。
1. Beepers h_a_v_e__b_e_e_n__r_ep__la_c_e_d_by mobile phones.

一、主动语态和被动语态
动词的语态表示的是主语和谓语之间的关系。 英语的语态分主动语态和被动语态。 主动语态(Active Voice)表示主语是动作的执行者。 被动语态(Passive Voice)则表示主语是动作的承 受者。只有及物动词才有被动语态。
The construction of the new lab must be completed by the end of next month.
4、科技文章、新闻报道、书刊介绍等媒体中, 突出描述的客观性。如:
Over 13 people have been killed in this accident so far.
Calculator can't be used in the maths exam. Books and newspapers in the reading room mustn't be taken away.
3. 为了使语气委婉,避免提及自己或对方而使用 被动语态,或由于修饰的需要,使用被动语态, 使句子得以更好的安排。如:
3.一般将来时
地铁将在明年完成。
The subway w__il_l_b_e__f_in_i_s_h_e_d_ next year.
1. 河上将建一座桥。 2. 如果你违反法律,你就会受到惩罚。
1. A bridge _w_i_ll__b_e__b_u_i_lt_ over the river. 2. If you break the law, you _w_i_ll_b_e__p_u_n_i_sh_e_d.
-al….的------------physical (形容词) -en变得------------ widen(动词) -ful充满-----------spoonful(形容词)
Mis- -ful--------------mistrustful不信任的 Un- -able-------------unbearable不能容忍的
一般现在时 Simple Present
1. 他经常嘲笑我。 2. 我经常被他嘲笑。
1. He often laughs at me. 2. I a_m__ often _l_a_u_g_h_e_d_a_t__by him.
2.一般过去时 Simple Past
1. 警察抓到一个小偷。 2. 一个小偷被警察抓到了。
1. The police caught a thief. 2. A thief _w__a_s _c_a_u_g_h_t_ by the police.

三、使用被动语态时应注意的几个问题
1. 含有情态动词的被动语态: 动词原形变成be+done
情态动词+do
情态动词+be+过去分词
be going to do be to do be sure to do used to do have to do had better do
be going to be done be to be done be sure to be done used to be done have to be done had better be done
5.现在进行时的被动语态
1. A stranger is following the girl.
The girl __i_s__b_e_in_g___fo_l_l_owbeyda stranger.
二、何时使用被动语态
1. 动作谁做的不知道,说出谁做的没必要。 如:
Paper is made from wood. The house was built in 1950. He was wounded in the fight. 2. 需要强调动作承受者。 如:
