英语高手进/帮我看看这段话,有没有语法的错误?One day,Robert and Lucy want to take

one day 过去的某天,用过去式比较好
所以want改为wanted
are改为were
the Claire人名前面不用加the
the car of her mother's
of 本身就表示的了,所以mother's 改成mother
help sb to do sth 或者help sb with sth
they are with heavy bag.be动词后面不能直接这么用的,可以改成they were working with heavy bags.（两个人两个包)

纠正如下：
One day, Robert and Lucy want to take the school bus with heavy bags. But the school buses were all full. When they met Claire, she helped them take her mother's car.
注意时态一致、单复数
her mother人的所有格不用of
连词的用法

怎么像我以前教的新概念上的东西。
1 要用过去时，所有的句子。
2 句子后面要用句号，要不就加and。
3 claire 前不要the
4 helps不对，是让他们，用lets。

以下为补充：
我看了上面的回答，按我的来就ok
比如...

首先要统一时态，过去式或者现在时
