命题点2 被动语态
在解答此类题目时,考生首先应判断题目是否考查被动语态,有两种方法:
①根据被动语态的基本结构来判断,若动作的承受者(动作的对象,多是名词或代词)在空前,实施者在空后(有时也省略),则用被动语态;②根据主语和谓语之间的逻辑关系来判断,若主语与谓语之间构成逻辑上的动宾关系,则用被动语态。
其次,根据语境、给出的时间状语或已经发生动作的时态来确定正确的时态。
最后,根据被动语态的结构,填写动词的正确形式。
1.被动语态的构成
(1)一般现在时
结构:am/is/are done
This machine is made in China.这台机器是中国制造的。
(2)一般过去时
结构:was/were done
The windows in our classroom were broken yesterday.
昨天我们教室的窗户被打碎了。
(3)一般将来时
结构:will/shall/be going to be done
I think the desks will be repaired soon.我想这些课桌很快要被修好了。
(4)含情态动词
结构:情态动词+be done
Where can the lost book be found?这本丢失的书能在哪里找到?
Waste paper shouldn't be thrown here.废纸不应该被扔在这儿。
2.主动语态变被动语态的方法
INCLUDEPICTURE"21AHRYY2.TIF" INCLUDEPICTURE "21AHRYY2.TIF" \* MERGEFORMAT
口诀:宾变主,主变宾,谓语动词用被动。
【命题专家点拨】
常见主动语态变被动语态的特殊情况
主动语态中有些感官动词(如hear,see,watch,notice等)和使役动词(如make,let等)后用不带to的不定式作宾语补足语,变为被动语态时,要把不定式符号to还原。例如:
hear/see sb. do sth.→sb. be heard/seen to do sth.make sb. do sth.→sb. be made to do sth.
3.使用被动语态的情况
(1)不知道动作的执行者是谁。
Rice is grown in the south of China. 中国南方种植水稻。
(2)没有必要指出动作的执行者。
Smoking isn't allowed in the gas station.加油站里不允许吸烟。
(3)需要强调和突出动作的承受者。
Your work must be finished today.你(们)的工作今天必须完成。
(4)句子的主语是物。
Many houses were washed away by the flood.许多房屋被洪水冲走了。
4.主动结构表被动意义的情况
(1)open, lock, write, read, sell, clean, watch, cut, burn, drive等作不及物动词时,当它们的主语为物时,可用主动结构表被动意义。
This kind of pen writes very smoothly.这种钢笔写起来很流畅。
(2)look, sound, taste, smell等感官动词用主动结构表被动意义。
Mooncakes taste very delicious.月饼尝起来很好吃。
(3)be worth doing用主动形式表被动意义。
This book is worth reading.这本书值得一读。
(4)want/need/require+doing相当于want/need/require+to be done。to be done为不定式的被动结构。
Your car needs washing.=Your car needs to be washed.你的汽车需要清洗了。
