 Ally: You haven’t read the news about Las Vegus shooting on October 1st,   31.    ?
 Ivan: No. I was busy preparing for the exam. What’s about the news?
Ally: It happened during a country music festival in Las Veuas . The news said that at least 58 people died and more than 500 got hurt in this attack. The shooting is the most serious one in modern US history.
Ivan: Oh, no. I can’t believe it. That’s terrible. Who did it?
Ally: The Las Vegus Police didn’t know the shooter’s name before the shooting, and they believed he acted alone. He bought   32.   many firearms legally in the past. The police found at least 23 weapons inside his hotel room.
 Ivan: How did he kill so many people?
 Ally: The police said the shooter fired on the crowd of about 22,000 people from the 32nd floor of the hotel for   33.     nine to 11 minutes. At that time, people didn’t know where this gunfire was coming from. They were just scared   34.   and running for safety.
 Ivan: Hearing the news is scary to   35.    me. I feel it strange that Americans can have guns. They use guns not only to protect themselves but also to kill others. Maybe it’s time for them to think carefully about the gun control.
Ally: You’re right. There are two sides to every question.
Ivan: That’s a wise saying, I agree. And, my father always says “Experience is the best teacher.” I hope people around the world can learn a lot from it.
Ally: Water is a boon in the desert, but a drowning man curses it. One more saying to share with you. After all, to use guns or not, this is really a problem.
