有错误!
固定句式：
There is sth doing /done
要用这个句式,可以改为：
There is nothing 【needing 】to be forgot unless you want to escape.
=There is nothing needing forgetting unless you want to escape.
=There is nothing 【which needs 】to be forgot unless you want to escape.
=There is nothing 【which needs 】 forgetting unless you want to escape.
也可以改为：
There is no need to forget anything unless you want to escape.
祝你开心如意!
