He thumbed the red button at the top of the gun, and pulled the trigger again. Same thing.Then he pushed the white button. It gave a bright flash of light that illuminated a wide area, but not as intensely.The gun was quite cold when the button was pressed.The red button makes it like a laser-- but it is not a laser, Dap had said-- while the white button makes it a lamp.Neither will be much help when it comes to maneuvering.So everything depends on how you push off, the course you set when you start. It means we're going to have toget very good at controlling our launches and rebounds or we're all going to end up floating around in the middleof nowhere. Ender looked around the room. A few of the boys were drifting close to walls now, flailing theirarms to catch a handhold. Most were bumping into each other and laughing; some were holding hands and goingaround in circles. Only a few, like Ender, were calmly holding onto the walls and watching.One of them, he saw, was Alai. He had ended up on another wall not too far from Ender. On impulse, Enderpushed off and moved quickly toward Alai. Once in the air, he wondered what he would say. Alai was Bernard'sfriend. What did Ender have to say to him?Still, there was no changing course now. So he watched straight ahead, and practiced making tiny leg and handmovements to control which way he was facing as he drifted. Too late, he realized that he had aimed too well. Hewas not going to land near Alai-- he was going to hit him."Here, snag my hand!" Alai called.Ender held out his hand. Alai took the shock of impact and helped Ender make a fairly gentle landing againstthe wall."That's good," Ender said. "We ought to practice that kind of thing."第 64 页 共 340 页http://www.en8848.com.cn/ 原 版 英 语 阅 读 网
