一、 肯定句改否定句的方法 一步法1、在 be 动词后力口 not如：is not ， are not ， am not， was not， were not；2、在 can，等后力口 not如：cannot3、 上述都没有的，在动词前加助动词否定形式do not, does not. （don' t/doesn' t）4、 some 改成 any二、 肯定句改一般疑问句的方法 三步法1、 把be动词放在句首，剩下的照抄，（some改成any，my改成your等）句点改成问号2、 把can，等放到句首，剩下的照抄，（some改成any，my改成your等）句点改成问号例如：陈述句：They are in the park.He can play the guitar..一般疑问句：Are they in the park?Can he play the guitar?把下列句子变成一般疑问句 am listening to music.is a student.can lean the classroom.are in the zoo.5. There are some flowers in the vase.6. This is my sister.7. We are sweeping the floor.3、上述都没有的，在句首请助动词Do/Does帮忙，剩下的照抄，（some改成any，my改 成your等）句点改成问号。
例如：陈述句：I like the ducks.He likes the dogs.一般疑问句：Do you like the ducks?Does he like the dogs?把下列句子改为一般疑问句n eed some masks. like maki ng the puppet. 3. Su Hai and Su Yang live in a new house.4.1 put a book on my head. 5. They sing "In the classroom” together.6. We play basketball on Su。
