八年级英语语态转换练习题40题(答案解析)
1. The students clean the classroom every day. (改为被动语态)
A. The classroom is cleaned by the students every day
B. The classroom are cleaned by the students every day
C. The classroom cleans by the students every day
D. The classroom cleaned by the students every day
答案：A。

解析：一般现在时的被动语态结构是“be+过去分词”。

原句中主语是the students，谓语是clean，宾语是the classroom。

改为被动语态时，将宾语the classroom变成主语，因为classroom是单数，所以be动词用is，clean的过去分词是cleaned，“by the students”表示动作的执行者，所以答案是A。

主动语态强调动作的执行者，句子结构是“主语+谓语+宾语”；被动语态强调动作的承受者，结构是“主语（原宾语）+be+过去分词+（by+原主语）”。

2. My mother makes a delicious cake. (改为被动语态)
A. A delicious cake is made by my mother
B. A delicious cake are made by my mother
C. A delicious cake makes by my mother
D. A delicious cake made by my mother
答案：A。

解析：一般现在时主动语态改为被动语态，原句主语my mother，谓语makes，宾语a delicious cake。

变为被动语态时，宾语a delicious cake作主语，是单数，be动词用is，make的过去分词是made，动作执行者用by引出，所以是A。

主动语态中主语执行动
作，被动语态中主语承受动作。

3. Teachers often use computers in class. (改为被动语态)
A. Computers are often used by teachers in class
B. Computers is often used by teachers in class
C. Computers often used by teachers in class
D. Computers use by teachers in class
答案：A。

解析：一般现在时的被动语态形式。

原句主语teachers，谓语use，宾语computers。

改被动时，computers作主语是复数，be 动词用are，use的过去分词是used，“by teachers”表示动作执行者，所以答案为A。

主动语态描述主语的动作，被动语态描述主语被怎样对待。

4. The gardener waters the flowers every morning. (改为被动语态)
A. The flowers are watered by the gardener every morning
B. The flowers is watered by the gardener every morning
C. The flowers water by the gardener every morning
D. The flowers watered by the gardener every morning
答案：A。

解析：一般现在时被动语态构成。

原句中the gardener 是主语，waters是谓语，the flowers是宾语。

变为被动语态时，the flowers作主语，为复数，be动词用are，water的过去分词是watered，“by the gardener”表示动作执行者，故答案是A。

主动语态中动作执行者在句首，被动语态中动作承受者在句首。

5. My father reads newspapers every evening. (改为被动语态)
A. Newspapers are read by my father every evening
B. Newspapers is read by my father every evening

原句主语my father，谓语reads，宾语newspapers。

改成被动语态时，newspapers作主语是复数，be动词用are，read的过去分词是read，“by my father”表示动作执行者，所以答案为A。

主动语态强调施动者的动作，被动语态强调受动者的状态。

A. His clothes are washed by the boy on weekends
B. His clothes is washed by the boy on weekends
C. His clothes wash by the boy on weekends

答案：A。

解析：对于一般现在时主动改被动。

原句the boy是主语，washes是谓语，his clothes是宾语。

被动语态中，his clothes作主语是复数，be动词用are，wash的过去分词是washed，“by the boy”表示动作执行者，所以A正确。

主动语态中主语主动进行动作，被动语态中主语被动作影响。

A正确；选项B缺少be动词；选项C中“is”为一般现在时be动词，时态不对。
