A young man was getting ready to graduate from college. For many months he had admired a beautiful sports car in a dealer's showroom, and knowing his father could well afford it, he told him that was all he wanted.

As Graduation Day approached, the young man awaited signs that his father had purchased the car. Finally, on the morning of his graduation, his father called him into his private study. His father told him how proud he was to have such a fine son, and told him how much he loved him. He handed his son a beautiful wrapped gift box. Curious, but somewhat disappointed, the young man opened the box and found a lovely, leather-bound Bible, with the young man's name embossed in gold. Angrily, he raised his voice to his father and said, "With all your money you give me a Bible?" He then stormed out of the house, leaving the Bible.

Many years passed and the young man was very successful in business. He had a beautiful home and a wonderful family, but realizing his father was very old, he thought perhaps he should go to see him. He had not seen him since that graduation day. Before he could make the arrangements, he received a telegram telling him his father had passed away, and willed all of his possessions to his son. He needed to come home immediately and take care of things.

When he arrived at his father's house, sudden sadness and regret filled his heart. He began to search through his father's important papers and saw the still new Bible, just as he had left it years ago. With tears, he opened the Bible and began to turn the pages. As he was reading, a car key dropped from the back of the Bible. It had a tag with the dealer's name, the same dealer who had the sports car he had desired. On the tag was the date of his graduation, and the words. "PAID IN FULL".

How many times do we miss blessings because they are not packaged as we expected? Do not spoil what you have by desiring what you have not; but remember that what you now have was once among the things you only hoped for.

Sometimes we don't realize the good fortune we have or we could have because we expect "the packaging" to be different. What may appear as bad fortune may in fact be the door that is just waiting to be opened.

①在走向茫茫宇宙的过程中，神通广大的航天器是人类征服宇宙的最有力的武器。航天器可分为无人和载人两种。无人航天器包括人造地球卫星、空间探测器和空间平台等；载人航天器包括栽人飞船、空间站、航天飞机、空天飞机等。其中，正在研究的“空天飞机”，有人将其誉为21世纪的“全能超级明星”。空天飞机是美国国家航天委员会正在设计的一种最新型的航天交通工具，它的全称是“国家航天航空飞机”。在理论上，它结合了航空、航天两大领域的技术精华，既有水平起飞、水平降落和可重复使用的航空技术的优点，又具有高速、高空等航天技术优点，是集航空、航天一体化的高技术密集的航空交通工具，具有极为诱人的发展前景。
②目前，英、法、德、日等国家已经各自推出了自己的开发计划，在空天飞机的研究上展开了激烈的竞争，从而在全球掀起了一股“空天飞机热”，引起了世界的普遍关注。专家认为，空天飞机的投入使用，将给未来的空间计划带来更加光明的前景，将使人们的空间旅行和航空观念发生革命性的变化。
③空天飞机可以水平起飞，采用航空喷气发动机和火箭发动机两种推进系统，可谓是“空”和“天”的完美结合。它具有异乎寻常的性能。最高时速达3万千米，这是第一宇宙速度。绕地飞行高度从零高度直达200千米以上的绕地轨道高度。起降方便，不受“发射窗口”天气和起降地带的限制。一机多用，既可作为太空作业平台，又可从事太空和常规军事活动。最重要的是，空天飞机较之现今的航天飞机发射有效栽荷入轨的费用要低90%，而且不需要规模庞大、设备复杂的航天发射场。至于在太空中完成航天飞机能完成的发射、回收、维修卫星和飞船等航天器的任务，就更加简便易行了。
④空天飞机将是人类在21世纪最引人注目的研究课题。在繁星点点的夜里，当我们仰望黑漆漆的夜空，看到划过的一道流光，或许就是人类乘坐空天飞机在太空飞行的轨迹。
