解答：在“Would you like to do sth? ” 和“ Would you please” 表示“请求的句型中” 变为间接引语时，用动词不定式表示。

【1】 She said to me: ,“Would you like to help me with my English?” 

改为间接引语为下面句子

She asked me to help him with his English.

【2】The young woman said to me:,”Would you please do me the favor to carry the box upstairs?”

改为间接引语为下面句子

The young woman asked me to carry the box upstairs for her.

备注：在“不是表示请求的一般疑问句中”则使用连词if/whether变为宾从句

The teacher said, “Will you be back today?” 改为间接英语

The teacher asked (him) if/whether he would be back that day.

    如果直接引语是表示请求含义的 "would you please ..."这种疑问句，变为间接引语应该是ask sb to do sth，例如：

        "Would you please spare me a few minutes ?" He asked me to spare him a few minutes. (摘自赵俊英：《现代英语语法》p.1256)""

        所以，His wife said to me: "would you please step in and wait？" 中的 "would you please step in and wait？"是疑问句， 间接引语是：His wife asked me to step in and wait.
