这是一道介词填空题，解题思路是先理解每个句子的语境，再结合常用介词的固定搭配和语义用法选择合适的介词。需重点掌握常见介词的固定短语（如be made of、at the age of等），以及介词在不同语境中的含义（如with表“带有/和”、without表“没有”、by表“通过方式”等）。
【解析】
1. 固定搭配be made of表示“由……制成”，符合桌子由塑料制成的语境，故填of；

6. 固定结构too...for sb to do sth表示“对某人来说太……而不能做某事”，故填for；
7. 固定短语work on sth表示“致力于、从事于某事”，符合“致力于解决问题”的语境，故填on；
