【正确答案】：E
【题目解析】：在对话中，John表示对于周六去野餐的想法感到很棒，但随后他提出了一个问题（通过"But?"表达），而Mary则建议了Blue Mountain作为野餐地点。John认为这是一个好主意，并建议邀请Michael和他的女朋友一起。Mary同意了这个建议，并补充说“It would be great fun to have them with us.”（有他们和我们一起会很有趣）。 因此，第57题的答案应该是与Mary这句话相匹配的选项，即表达“很有趣”或“很愉快”的意思。在给出的选项中，E选项“be great fun”与Mary的表述相吻合，表示与他们一起会很有趣。 所以，正确答案是E。
