　　楼主的这个句子有误，正确表达应该是：This is my friend.

1. 否定句：This isn't my friend.

   含be动词的否定句是在be动词的具体形式后加not。又如：

   I am a student.---I am not a student.

   They are at school. ---They aren't at school.

2. 一般疑问句：Is this your friend?

   1) 含be动词的一般疑问句是将be动词的具体形式提前到句首。又如：

   Tom is in red.---Is Tom in red?

   His parents are teachers.---Are his parents teachers?

   2) 陈述句中的第一人称的代词，在疑问句中要改成对应的第二人称的代词。又如：

   I am a student.---Are you a student?

   It is mine.---Is it yours?

参考吧~~
