When I was a junior high school student in 1980, God gave me a gift, and it was happiness.

    One weekend, I went to visit my grandparents in the countryside. On my way home a car ran over me and broke off my1because of its high speed.

    Several days later when I woke up at the hospital, I realized(意识) I had to spend the rest of my life2arms. How sad I felt at that time! I was full of fears.3slowly I knew I had to face the fact and got over it. I couldn't get my arms back even though I4 every day.

    5, it's easier said than done.6took me nearly half a year to get out of the sadness completely. I got so much from my past story. From then on, I could treat(对待)my life with a7mind. But in our daily life, I often see my classmates8about little things: They get a bad grade on a test; their bus comes9; they don't have a mobile phone but10do, and so on. But I only11life. I was lucky to realize from an accident that it is a waste(浪费) of our life to focus on(集中注意力)12you have lost. We13always think of what we have. So why are so many people unhappy? Someone may say, “My whole life would improve14I have a new car.” But when you get the car what happens? For a whole week you are walking on air. Then you go right back to being unhappy.

    Happiness depends on what we have! It's in our heart. It's a state of mind, even though you own the whole world, you may still feel15. Happiness comes from mastering the art of appreciating(感激) and taking pleasure in what you really have.

阅读【甲】【乙】两段选文，完成下面题目。
                                                                                                 【甲】活板
      庆历中，有布衣毕昇，又为活板。其法：用胶泥刻字，薄如钱唇，每字为一印，火烧令坚。先设一铁板，其上以松脂、蜡和纸灰之类冒之。欲印，则以一铁范置铁板上，乃密布字印，满铁范为一板，持就火炀之；药稍熔，则以一平板按其面，则字平如砥。若止印三二本，未为简易；若印数十百千本，则极为神速。常作二铁板，一板印刷，一板已自布字，此印者才毕，则第二板已具，更互用之，瞬息可就。每一字皆有数印，如“之”“也”等字，每字有二十余印，以备一板内有重复者。不用，则以纸帖之，每韵为一帖，木格贮之。有奇字素无备者，旋刻之，以草火烧，瞬息可成。不以木为之者，文理有疏密，沾水则高下不平，兼与药相粘，不可取；不若燔土，用讫再火令药熔，以手拂之，其印自落，殊不沾污

                                                                                               【乙】石油
       鄜、延①境内石油，旧说“高奴县出脂水”，即此也。生于水际②，沙石与泉水相杂，“惘惘”③而出，土人以雉尾挹④之，乃采入缶⑤中，颇似淳⑥漆，燃之如麻⑦，但烟甚浓，所沾帷幕皆黑。予疑其烟可用，试扫其煤以为墨，黑光如漆，松墨⑧不及也，遂大为之。其识文⑨为“延川石液”者是也。此物必大行于世，自予始为之。盖石油之多，生于地中无穷，不若松木有时而竭。
     【注】 ①鄜、延：鄜州、延州，在今陕西延安一带。②水际：水边。③惘惘：涌流缓慢的样子。④雉尾挹之：雉，野鸡；挹，原指舀水，此处指沾取。⑤缶：陶瓷罐子。⑥淳：同“纯”。⑦麻：此处指麻杆。⑧松墨：我国名墨之一，用松烟制成，故称“松烟墨”。⑨识文：标上名称。
