还有,这五个选项为什么选这个答案,要分别解析一下,

1.-听!Nancy在隔壁房间唱歌.
-不可能是Nancy.她在老师的办公室.
这个首先根据上下文,可以知道是否定意思.所以可以排除C,D两项.mustn't否定意思表示禁止,不符合原句意思.所以选A
2.表示肯定的猜测.用must.I think she must be ill.选C
3.-Peter,这是谁的书?
-这是Danny的书.
it指的是书,所以与Danny是所属关系.应该用belong to表示属于.选D
4.water是不可数名词,much可以修饰.too在此作"太"讲.用于形容词或者副词之前.选A
5.反义疑问句.
陈述部分肯定式+疑问部分否定式.选D
不知道我解释的你能不能明白!
