Brianna sighed. I could tell she didn’t want to sacrifice precious minutes of her own recess to do what I was asking of her, but I also knew her heart. She often thought of others before herself - a rare character for anyone, much less a kid.
Knowing this choice was hard for her, I pulled out a D-buck, our class currency. Though bribery (行贿) was not the ideal way to handle this situation, I needed her cooperation.
“Here, I’ll pay you for your time.”
She offered an insincere smile, grasped the green paper, and headed down the hill. As the rest of the children screamed and laughed, my eyes locked on Brianna as she neared the picnic table. Molly could be difficult, and I wouldn’t have been surprised if she sent Brianna hack alone, refusing her invitation. When she encouraged herself to a standing position, I sighed with relief.
A minute later, I felt a lap on my shoulder. “Here, Mrs. D.” She handed me the D-buck. “Why?” I asked.
“I shouldn’t keep this.” Her eyes fell to her feet, guilt radiating from her quiet voice. “I don’t want Molly to think I only went to get her so I could earn a D-buck. She’s my friend.”
A moment later, they were all laughing again, and who should I see among them, laughing for the first lime that week? Molly. 28. How was Molly in the author’s eyes? A. She often made fun of others. B. She got on well with other kids. C. She was eager to be accepted.

Astronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.
Tethers Unlimited Inc., an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.

it into 3D filament (长丝).
The filament will e used in a 3D printer on the ISS-called the Refabricator-to make tools, spare parts and satellite components.
The waste will come from packaging materials, food containers, trays and eating utensils (器具) used on the ISS. Astronaut currently use disposable wet wipes to clean their food containers and utensils. The used wipes are stored as trash (垃圾), and replacement wipes must be sent up to the ISS on cargo missions.
By recycling old food containers and utensils, astronauts will reduce the amount of trash they produce. To get rid of trash from the ISS, astronaut load it into empty cargo capsules (航天舱) and release it into space. The capsules burn up when they enter Earth’s atmosphere.
Turning trash into useful new items will also help NASA save money because astronauts will need fewer supplies. It costs about $ 6,000 for every kilogram launched into orbit. These benefits will be even more important for longer missions in the future-such as the two-year journey to Mars. Astronauts will be able to recycle old waste materials into new tools and parts as they need them.
Tethers have successfully tested the systems in its laboratory. They will test it on the ISS in late 2018. The company is also developing a version of the system for use here on Earth. 32. What material are the forks and knives for astronauts made of? A. Gold.
