Last Sunday,Linda went to the park by bike at 11 am.The weather was nice.Some people were swimming in the river.While Linda was watching the people,a boy got out of the trees.He (rode) Linda's bicycle away after 10 minutes.But Linda didn't know.
It was time to have lunch.Linda wanted to ride her bicycle (to go) home.But she couldn't find (it).Then she (cried) while she was calling the police.
1.整篇为一般过去时,所以用ride的过去式rode；
2.get home为“到家”,不如go home“去/回家”更通顺；
3.cry动作发生在call the police动作期间,所以前者用一般过去时,而后者用过去进行时.
4.此文有些单词短语重复使用,比如her bicycle,所以有时候能换种说法（比如改成it）.
