W:Mike,do you want to go to the hospital and see Sam this afternoon?
M:What has happened to him?Is he ill?
W:No.Haven't you heard about it?He was hit by a car while he was riding his motorbike to school this morning.
M:Oh,I'm so sorry to hear that.I really knew nothing about it.I hope it's not serious.
W:It was said that he went a few meters away before he stopped.Luckily,he was wearing his helmet,so his head was well﹣protected.
M:Have they had him fully examined?
W:I really have no idea.I hope he is not injured.So will you go?
M:Absolutely.
