2、e in the same school. 他们在同一所学校。The dogs are small. 那些狗很小。（2）歌谣：be动词多变化，am, is 还有are；变否定很简单，not放在be后面；变疑问往前提，句首大写莫迟疑；还有一点要注意，句末问号别忘记。注意：在含有be动词的句子，变否定句时在be动词后加not；变一般疑问句把be动词提前。Eg: (1)I am a good girl.- Im not a good girl.- Are you a good girl? 肯定回答：Yes, I am .否定回答：No, Im not.(2)He is from English.-
