Wish there was some place we could swim.
1 这是Wish开头的祈使句吗?wish后面是省略that的宾语从句吗?Wish (that) there was some place we could swim.
2 some place (that) we could swim,we could swim是定语从句修饰some place吗?that是关系副词,相当于where吗?
你的分析基本是对的,只是句子开头的 Wish 并非是祈使句,而是省略了主语 I 省略句。
Wish there was some place we could swim.
=I wish there was some place we could swim.
