概括下面一段材料的主要内容。（不超过48字）

　　钛合金强度大，重量轻，耐热性能好，适用于船只、汽车、航空航天工业，被人们视为未来材料。新型波音777客机采用了约9%的钛合金材料。然而，钛合金的加工难度极大，如加工一个钛合金船用涡轮压缩机轮需要50个小时，而加工一个铝合金的同样部件仅需5个小时。德国布伦瑞克大学的科学家采用了一种专门热处理方法，将氢原子渗入材料，掺氢的钛合金相对软化。对软化的钛合金进行切削加工，加工设备所承受的机械和热负载明显降低，切削力仅需过去的50%，大大降低了加工成本。加工完毕后，再经专门的热处理工序，材料的特性则回到原先状态。科学家称，该方法非常适用于大批量的钛合金铸件加工。

When my son, Mark, was in the third grade, he saved all his pocket money for over three months to buy holiday presents for those he loved. He had 1 twenty dollars.      The third Saturday in December, Mark said he had 2 his list and had his money in his 3 . I drove him to a 4 supermarket. Mark picked up a hand basket and went off on his own 5 I waited 6 reading a book at the front of the store. It 7 Mark over 45 minutes to choose his presents. When he came up to the checkout(结账台), the smile on his face was truly 8 . The clerk rang up his purchase(在收款机 输入金额)as I politely looked at the other way. Mark kept 9 his budget and 10 into his pocket for his money. 11 was not there! There was a hole in his pocket, but no money. Mark stood 12 the store holding his basket, tears rolling down his cheeks. His whole body was 13 with his sobs. Then a(n) 14 thing happened. A 15 shopping in the store came up to Mark. She knelt down and took him 16 her arms. "You would do me the favor if you let me 17 your money," said the woman. "It would be the most wonderful present you could ever give me. I only ask you could 18 . One day, when you grow up, I would like you to find someone you can help. I know you feel as good about it 19 I do now when you do help other people." Mark took the money, tried to dry his 20 and ran to the checkout as fast as he could go.
