There isn't any (?) in structure between the two machine.括号里填different还是difference还是differe

be different+<Adj> from =There be difference/different+<N> between A and B.

different 是形容词，difference 是名词
there are some differences between a and b
=a is different from b 应该是这样用

different
题干错了，应为：There are differences between different persons

difference
any+名词
different 形容词
differ动词
difference名词
“这两台机器在结构上没有任何不同”

填difference，因为any用在疑问句, 否定句, 条件从句中, 代替 some，表示“ 一些, 什么”。例如：I don't have any choice.我没什么选择。
