答案： 1. To see if wood can work in space/can cut down space pollution. 由第一段的 Scientists want to see if wood can work in space. If successful, wooden satellites could cut down space pollution. 可知，把木制卫星送入太空的目的是测试其是否能正常运行/是否能减少太空污染。
2. Because there's no water or air there. 由第二段的 In space, wood becomes stronger. There's no water to wet it or air to burn it. 可知，木材在太空中会变得更坚固，是因为它处于没有水、没有空气的环境中。
3. It is light, strong, and doesn't break easily. 由第三段的 They chose a special wood for the satellite. It is light, strong, and doesn't break easily. 可知，这种特殊的木材重量轻、强度高，而且不容易断裂。
4. Water and carbon dioxide/CO₂. 由最后一段的 But when wood burns, it only leaves water and carbon dioxide behind. 可知，木质卫星最后变成水和二氧化碳。
5. It's meaningful/helpful/important. Because it is cleaner.（答案不唯一，合乎情理即可）
