帮忙翻译一下这张请假条，非常感谢！！

because the Gastric ulcer, she want to ask for leave and staying home for a rest, If the sick turn bright, She will joy the class.

1楼通篇语法错误

准确的如下：
Because she gets the gastric ulcer, she needs to stay home for a rest. Hardly will she go to school, when she gets well.

She asks for a sick leave because of the gastric ulcer. She needs to take a rest for a period of time at home before going to class.

有一位朋友说我译的这句话错误严重，让人不明白。请教一下：哪些地方错了？什么让人不明白？

He has got gastric ulcer,she needs take a rest at home for a while,she will back to school after recovering from illness.

仅供参考！

She asks for a sick leave because of the gastric ulcer. She needs to take a rest for a period of time at home before going to class.
这个是 错误的，别的都还行，严重的叫人看不明白

Because she had gastric ulcer, and will therefore take some time to rest at home to go to class.
