This would be the  16  time that his classmates and teacher met his mother and he  17  lose his face because of her appearance. Although she was a  18  woman, there was a scar(疤痕) that covered nearly the whole right side of her face. The boy never wanted to  19  why or how she got the scar.
At the meeting, the people were   20  by the kindness and natural beauty of his mother even though she had the scar on her face, but the little boy was still embarrassed(尷尬) and hid himself from everyone.   21 , he happened to hear of a talk between his mother and his teacher.
The teacher asked  22 , “How did you get the scar on your face?”
The mother replied, “When my son was a baby, he was in a room that caught fire. 23 was too afraid to go in because the fire was  24 , so I went in.    25 I was running toward his bed, I saw a long piece of wood  26 and I placed myself over him trying to protect him. I was knocked senseless(失去知覺(jué)) but luckily, a fireman came in and saved both of us.” She  27 the burned side of her face. “This scar will be there forever, but to this day, I have never  28 what I did.”
At this point, the little boy came out running toward his mother with  29 in his eyes. He held her in his arms and felt a great sense of the sacrifice(犧牲) that his mother had made for him. He held her hand  30  for the rest of the day.

When are you an adult (成年人)？
When do you think you are an adult ? Maybe different __31_ have different ideas.
Now let’s see what some American teenagers(青少年)say .
Sam: In  32 idea ,you are an adult at the  33  of 18. That’s when you can vote(投票)。You can help to   34  who rules(統(tǒng)治)the whole country .That’s also a grown-up does! My grandfather couldn’ t vote   35 he was 21.They changed（改變） it to 18 in 1971.
Jenny：I don’t 36  it’s hard to say . I can drive a car at 16, can’t I ?When you have a driver’s licence , you can 37 it to people to tell them your age for all kinds of things .  38    sixteen must be the age when you change from a  39  person to an adult.Because you can tell others you are not a  40   any more .
Suzie : Well , I think there is  41   wrong with American laws for when young people can  42  things . I can vote at 18 and drive at 16. So you would think 18 is a grown-up,  43  16 isn’t .But then I can’t drink wine（酒）until I’m 21 ! If I’m 44   an adult at 18, how can people stop me from  45   a cup of beer in a bar ?
