三、1. grandparents 2. cleaning the house 3. making a fruit cake
4. sister

【分析】
首先，我们需要明确题目要求是根据短文内容完成Betty家人活动的思维导图。解题思路如下：
1. 先通读短文，定位每个家人对应的活动描述，或者每个活动对应的家庭成员；
2. 逐个对应思维导图的空格：
第一个空格后是“are cooking”，在短文中找到对应描述，确定该家庭成员；
第二个空格是father对应的动作，从短文里提取爸爸正在做的事；
第三个空格是mother对应的动作，找到妈妈的活动描述；
第四个空格对应“making a card”的主体，从短文中找到执行该动作的家庭成员。
【解析】
1. 根据短文句子“Betty's grandparents are cooking.”，可知正在做饭的是grandparents，故第1空填grandparents；
2. 由短文“Her father is cleaning the house.”可知，爸爸正在打扫房子，故第2空填cleaning the house；
3. 根据短文“Her mother is making a fruit cake.”可知，妈妈正在做水果蛋糕，故第3空填making a fruit cake；
4. 从短文“Her sister is making a card by herself.”可知，制作卡片的是sister，故第4空填sister。
【答案】
1. grandparents
2. cleaning the house
3. making a fruit cake
4. sister
