( )2. Sarah's mother likes dancing and reading.
( )3. Sarah and her grandfather have the same hobby.
( )4. Sam likes drawing, but he's not good at it.
( )5. There are four people in Sarah's family.

【解析】：本题是一个阅读理解判断题，需要根据给出的短文内容，判断每个句子是否与短文内容相符。
1. 第一个句子“Sarah's father is a bus driver.”与短文中“Her father is a doctor.”这一句相矛盾，所以判断为不相符。
2. 第二个句子“Sarah's mother likes dancing and reading.”与短文中“Her mother is a teacher. She likes dancing and shopping.”这一句不完全相符，因为短文中并未提及Sarah的母亲喜欢阅读，只提到了她喜欢跳舞和购物，所以判断为不相符。
3. 第三个句子“Sarah and her grandfather have the same hobby.”与短文中“Sarah's grandfather is a bus driver. He likes listening to Beijing opera(京剧)very much. But Sarah doesn't. She likes pop music(流行音乐).”这一句相矛盾，因为Sarah和她的祖父的爱好并不相同，所以判断为不相符。
4. 第四个句子“Sam likes drawing, but he's not good at it.”与短文中“He likes drawing pictures. But he can't draw well now.”这两句相符，所以判断为相符。
5. 第五个句子“There are four people in Sarah's family.”与短文内容不相符，因为短文中提到了Sarah的父亲、母亲、弟弟和祖父，再加上Sarah自己，至少有五个人，所以判断为不相符。
