2.

Don't take too much medicine.
3. However, if you take too much medicine, you may get into trouble. "Some people take medicine too much and their body is hurt or even some of them lose their lives," says Dr Marinov.

"A fever makes your metabolism(新陈代谢) faster. You need something more from food," says Dr Marinov. 4. Food lets you have more energy to get better when you have a fever.
Don't forget to drink water.

1.C 2.B 3.E 4.D 5.F

我们可以根据上下文逻辑逐一匹配选项：
1. 空前句提到发烧时有些不能做的事，后文开始逐条列举医生给出的注意事项，C选项“Here are some of them shared by doctors.”起到承上启下的作用，符合语境。
2. 空后内容核心是发烧时不要穿太多衣服，否则会加重发烧，B选项“Don’t wear too much.”和后文内容对应，也和其他“Don't...”的小标题格式统一。
3. 空后用However转折说明吃太多药会有危险，空处需要铺垫合理用药是有帮助的，E选项“Right medicine does help when you’re having a fever.”符合此处转折的逻辑。
4. 本段主题是发烧时不要饿着，空前说明发烧时代谢更快需要从食物获取更多，空后说明食物能提供恢复的能量，D选项“Being hungry will be bad for your body health.”衔接上下文，呼应“不要挨饿”的主题。
5. 空前提到发烧会加快呼吸频率造成水分流失，空后说明最终会导致严重脱水，F选项“What’s worse, people usually drink less water during a fever.”递进补充另一个会造成脱水的原因，逻辑连贯。
多余选项为A。
