Grammar---嵌入式问句（embeddedquestions）

嵌入式问句（embedded questions）：将一个问句嵌入到 Can you tell me...? Do you know...? Did you...? 等类似句型里，该问句需要转换为陈述语序。嵌入规则主要有：

 1.如果问句的谓语动词是 be 动词，调换 be 动词和主语的位置。如：Where are you? → Can you tell me where you are?

2. 如果问句含有 do / did / has 等助动词，要删去该助动词，将谓语动词变为相应的时态形式。如：Where did he go? → Did you see where he went?

3. 如果疑问句中没有疑问词（where, what, who 等），要在问句前加 if 或 whether。如：Does he live here? → Do you know if he lives here?

A. Change the questions.

B. Complete the conversation with embedded questions,using the questions in brackets to help you.
