帮我改一个英文句子给25分请大家帮我改改大写，标点符号措辞，改完了吧正确的写出来

Please leave Shauna read Carl's Newsweek magazine since Carl has already wrote his report.

Please在句首，所以大写
Shauna Carl是人名 ，要大写
Newsweek 是杂志名，也要大写
这句话是说 只要卡尔写完他的报告，就让肖娜看卡尔的每周新闻。

Please leave shauna read carls newsweek magazine since carl has already wrote his report。
这是一个从句。
大概是说“当carl 写完他的报告，请留下 shauna read carls newsweek magazine

Please leave Shauna read Carl's Newsweek magazine since Carl has already wrote his report.
当卡尔已经写完了他的报告时,请留下莎娜看卡尔得<每周新闻>杂志.
那个LEAVE是不是写错了.是不是LET啊?这样写怪怪得..
