欢迎你来某地玩儿怎么说？

望文生义版是这样儿的：You’re welcome to come to xx to play. xx指某地。

中英词汇没有一一对应关系。玩儿=play 有时候成立。比如说，The kids are playing.

但不是所有情况都成立。Play the guitar 就不是玩儿吉他而是弹吉他了。

精准掌握词汇要从英英释义入手。

Play: when children play, they do things that they enjoy, often with other people or with toys 这是play的一个意思。

欢迎你来某地玩儿能和这个词的意思相对应。

Visit: to go and spend time in a place or with someone, especially for pleasure or interest

欢迎你来某地玩儿，可以说Welcome to visit xx.

准确掌握词义，才不会用错。
