I am good a student I am a good student 哪个对 理由 I am a good student 英语短文《I am a good student》 I am a student.对还是I am student. I am a good student ,_____I?完成反意疑问句 I am a good student.改为复数形式 am,a,i,good,student,school,at连词组句 I am a very good student.有没有错? 反意疑问句如果主句从句都是第一人称对哪个提问?比如说I think I am a good student.______ I am a student. I am a good student.中a good student 这个词组是表语,还是只有student是表语? i am being a student.
