【分析】
本题考查宾语从句中that、if、whether的用法区别，解题思路为：先明确三者在宾语从句中的功能：that无实义、不充当从句成分，用于陈述事实的宾语从句；if和whether表“是否”，用于不确定的情况，其中有特殊规则：介词后、or not前、不定式前只能用whether，动词wonder、be worried about、be sure等后接表“是否”时，结合规则选择。逐题分析：1. wonder后表不确定，if/whether均可；2. 介词about后，只能用whether；3. guess后是陈述事实，用that；4. 有or not，用whether；5. says后陈述内容，用that；6. 有or not，用whether；7. tells后陈述要求，用that；8. Could you tell me后表不确定，if/whether均可；9. finds后陈述事实，用that；10. wonder后表不确定，if/whether均可。
【解析】
1. 动词wonder后接表“是否”的宾语从句，if和whether均可，故填if/whether；
2. 介词about后的宾语从句表“是否”，只能用whether，故填whether；
3. 动词guess后的宾语从句为陈述语气，用that（无实义，可省略），故填that；
4. 宾语从句后有or not，表“是否”时只能用whether，故填whether；
5. 动词says后的宾语从句陈述内容，用that，故填that；
6. 宾语从句后有or not，表“是否”时只能用whether，故填whether；
7. 动词tells后的宾语从句陈述要求，用that，故填that；
8. Could you tell me后接表“是否”的宾语从句，if和whether均可，故填if/whether；
9. 动词finds后的宾语从句陈述事实，用that，故填that；
10. 动词wonder后接表“是否”的宾语从句，if和whether均可，故填if/whether。

【分析】
本题要求将一般疑问句转换为宾语从句，解题思路如下：① 若原直接引语是一般疑问句，宾语从句的连接词用if或whether；② 宾语从句需使用陈述语序；③ 时态需与主句呼应：主句为一般现在时，从句时态可保持原时态；主句为一般过去时，从句需变为相应的过去时态（客观真理除外）；④ 从句人称需根据语境调整。
【解析】
1. 原句是一般疑问句，主句为一般现在时，连接词用if/whether，从句时态保持现在完成时，故填if/whether; has finished。
2. 原句是一般疑问句，主句为一般过去时，连接词用if/whether，从句一般现在时变为一般过去时，故填if/whether; had。
3. 原句是一般疑问句，主句为一般过去时，连接词用if，从句主语由you变为I，情态动词can变为could，故填I could。
4. 原句是客观真理，连接词用that，时态保持一般现在时，故填that; travels。
5. 原句是一般疑问句，主句为一般现在时，连接词用if/whether，从句时态保持一般现在时，故填if/whether; lives。
