One day ,Tom went to the park.He wanted to do some exercise.He was rope skipping beside the tree.Suddenly,the tree was broken off by the rope.Tom was very suprised,and he didn’t know how to do.Just then,he got a good idea.He used her rope to tie up the tree.After that,he sang a song and went back home happily.
第一，do some exercises. exercise是可数名词。
第二，rope skipping 是名词，所以应该是 skipping rope beside the tree.
第三，把tree 改成branch，因为是树枝被绳子打断了，而不是树被弄断了。
第四，是he didn't know what to do,意思是不知道该怎么办了（或是不知道该做些什么）。what作to do的宾语。
第五，he used his rope. he的宾格代词是his,she的宾格代词是her。
When he was rope skipping beside the tree,the tree was suddenly broke off by the rope. Tom was very suprised,and he didn’t know what to do.Then,he came up with a good idea.He used his rope to tie up the tree.After that,he sang a song and went back home happily.最后那句语法上没错，但是我估计和你想表达的意思不一样，你是不是想说他唱着歌回家了？要我说就是：He went back home singing a song happily.
He was skipping beside the tree. (注：skip单独就有跳绳的意思,不及物动词）
Suddenly,a branch was broken off by the rope.（树枝被折断,而不是树）
Tom was very suprised,and he didn’t know how to do it.（how是疑问副词,得加it.如果是what疑问代词就直接what to do.）
我翻译给您吧！倒是您看看有什么不通顺
