be动词构成的一般疑问句
一调：找到句中的be动词（am , is ,are)，把be动调到主语前
This is his book. Is this his book
二改：句中的主语若含有I (my /we )等第一人称代词时，需将它们改为you (your /you ）
This is my pencil . Is this your pencil
三问号：将句末的句号改为问号
如何将含be动词的肯定句变为否定句
一般将含be动词am, is ,are 的肯定句转化为否定句时，直接在be动词am, is ,are 后加上“not”即可。其他部分不变。
e.g.1. This is a ruler .
变：This is not a ruler .
2. I am a student .
变：I am not a student.
3. Tim and I are good friends.
变：Tim and I are not good friends .
口诀
be 动词真伟大，
生出am is are .
表示否定很简单，
not加在be 后边。
若要变为疑问句，
be应移到主语前。
还有一点要注意，
句末问号别忘记。
be动词用法口诀
我(I)用am，你(you)用are，
is连着他(he)，她(she)，它(it)，
其余单数用(is)，复数就用are。
