※ 引述《trtr112 (pk)》之铭言：
: 请教各位大大,
: It is said he will be staying here for 3 days. 如果我想把这句改为:
: He is said to 开头, 那正确写法是否为:
: He is said to be staying here for 3 days.
: 谢谢!
如果是:　
　　It is said that he will have been working for an hour by the time his boss
　　walks into the office.
　　那要如何用 "He is said to" 开头来改写呢?

你的句子意思怪异，基本上可视为错误(比如IELTS的essay这样子写是肯定是错误，因为不知所云)，因此用"He is said..."写也是意思怪异

He is said to have been…大概改写成这样
