1 The boy had a headache, he was shivering, his face was white and there were dark areas under his eyes.
2 Because the doctor knew the disease and left medicines for the boy.
3 The boy was worried because he thought he was going to die. The idea had bothered him since the doctor took the boy's temperature.
4 He was afraid that he would die.
5 The boy seemed very detached from what was going on.
6 It would've been natural, because children should trust their parents.
7 Yes, I like it. The boy's behaviour shows that he was a brave boy and he was worried about other people.
