一道高二英语选择题（请进！请详细说明！谢谢!)

Question

John's father , along with his uncle , ________ in New York one more day.
A demands that he stays
B demands that he stay
C demand that he stays
D demand that he stay

Answer 1

B 因为along with his uncle 为插入语，所以用谓语动词demands ,而demand that 后面为虚拟语气，接（should +) 动词原形，所以是stay .
类似的动词还有：advise， suggest，insist 等。

Answer 2

选C。
后面的状态好确定，一般现在时第三人称；至于前面，我认为along with在此处相当于and,是一个并列成份。

Answer 3

这一句应该选B.
首先，along with只是一个插入语成分，并不构成并列关系，这个句子主干还是John's father demands that...；其次，demand that sb. do sth.是一个固定结构，C是不对的

Answer 4

B,along with his uncle 为插入语，所以用demands ,demand that 后面为虚拟语气，接动词原形，所以是stay

Answer 5

选B。along with his uncle相当于汉语中的宾语补足语，是个介词，所以这个句子的主语是John‘s father，它是第三人称。再者，demand后跟动词原形，所以用stay。
