4.“tap-dancing to work”：“跳著踢踏舞工作”。tap原意是“叩擊、輕敲”；tap dance是“踢踏舞”。這里實際意思是“(手指)輕輕敲擊鍵盤的工作”。
5.PC(personal computer)：個人計算機
6.But for all the cool things that a person can do with a PC，there are lots of other ways we can put our creativity and in telligence to work to improve our world.要不是每個人利用個人電腦創造出如此多的美好事物，那我們也會有許許多多的其他方法將我們的創造性和智慧投入到工作中去改善我們的世界。本句中but for的意思是“要不是；若非”；com是美國俚語(=great;excellent)，意為“美妙的；很好的”，現在我國有人直接將其音譯為“酷”。
7.go unmet：得不到滿足。在這里go是系動詞，unmet是過去分詞作表語。
8.commit(oneself)to do sth..:致力于……
9.no less…than：和……一樣，不亞于….”
10.and that it doesnt take much to make an immense difference in these childrens lives：而且要將這些兒童的生命分出個三、六、九等來也是沒有什么意義的。本句中take，的意思是“獲得”，doesnt take much就是“得不到什么”的意思。此處it是形式主語，真正的主語是不定式短語 to make an immense difference in these childrens lives.
