以下三个句子求大神语法分析

语法分析：
1。Having a book publish 是主语,is是系动词谓语,a great achievement是表语；后段 success 主语,is系动词谓语,special表语。
2。Yuncheng主语,taught谓语,himself宾语,to write 是宾补（宾语发出的动作、宾语作的事）；When he was 17是时间状语从句,he wrote a letter 分别是主、谓、宾,后面describing his situation and his dreams of a better。是定语,修饰 a letter
3。book是主语,describes是谓语,what his life is like是宾语（从句）,后面的what his hopes and dreams are 以及and后面的how he overcomes the problems 是另外两个宾语（从句）,三个宾语从句是并列的,都给describes做宾语,最后部分he faces every day是一个定语从名,该从句修饰前一个名词problems。
希望以上分析对你解开疑问有所帮助。欢迎追问。
