根据材料内容选择最佳答案。 Kumar and his two friends built a robot and named it Athena. They would go for Battle of the Bots--the city's biggest robot competition, and it would start in two days. The winning team would get $5,000.
"How are we going to beat (打败) the Cougars?" asked Alex. The Cougars was the team that won the last two years' competitions.
Kumar said, "The Cougars always build a big and strong (强壮的) robot. But usually their robot isn't very fast."
"Our robot is fast," Alyssa said.
"Yes!" Kumar said. "Don't worry. I have a plan for how to do it." Kumar told the group his plan and they began to work.
Two days later, the competition began. Kumar said to his friends, "I' m sure the plan will work and Athena will win. Just wait and see."
Athena won all of her first battles (较量). The Cougars' big, strong robot, The Avenger, did well, too. By the end of the day, The Avenger and Athena were the only two robots left in the competition.
Soon the battle between Athena and the Avenger began. The Avenger lunged (猛扑) for Athena, but the small robot was too quick for him. Athena went behind The Avenger and, before the larger robot had time to turn, Athena hit (攻击) him from behind. The Avenger fell" down and couldn't move.
The three friends all jumped up excitedly. "Now it's time for the real question," said Alex“ ”
