【正文】 uced. The first 3D printer was invented in 1986 by American, Charles Hull. But 3D printing has only bee cheap enough recently for most people to use. Designers now use 3D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a manmade ear. But like a lot of new technologies, if 3D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3D printing to produce ATM skimmers. These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals like them might one day use a 3D printer to print a gun. But for better or for worse, 3D printing has been put into use. In a few years, you39。ll probably be wondering how you could ever live without your 3D printer!（1）________ invented the first3D printer.

I hated her. She was such an embarrassment. She ran a small shop at a flea （跳蚤） market and collected old clothes and some other things to sell for the money we needed. Once during elementary school, it was field day, and my mom came. I was so embarrassed and wondered how she could do this to me? I threw her a hateful look and ran out. The next day at school, my schoolmates laughed at me, Your mom only has one eye! I was so angry with my mom. So I said to my mom, Why don39。t you have the other eye? My mom said nothing. I hated my oneeyed mom. I told myself that I would bee successful in the near future, so I studied very hard. Later, I got accepted by the Seoul University. I left my mom and came to Seoul to study. Then I got married there. Now I am living happily as a successful man. I enjoy the life in Seoul because it39。s a place that doesn39。t remind me of my mom and my past. This kind of happiness was getting bigger and bigger, until one day I saw my mom. She was still with her one eye. Even my daughter ran away, scared of my mom39。s eye. I screamed at her, Who are you? I don39。t know you! How dare you e to my house and scare my daughter? To this, my mom quietly answered, Oh, I39。m so sorry. I may have gotten the wrong address. Then she disappeared out of sight. One day, a letter about a school reunion （學(xué)校聚會(huì)） came. After the reunion, I went down to the old shack, which I used to call a house. There I found my mom fallen on the cold ground. Then a piece of paper in her hand came into my eyes. It was a letter to me.My son, I39。m so sorry that I only have one eye, and I was an embarrassment for you. When you were very little, you got into an accident and lost your eye. As a mom, I couldn39。t stand watching you having to grow up with only one eye. So I gave you mine. I was so proud of my son to see a whole new world for me with that eye. During the couple of times that you were angry with me, I thought to myself, it39。s because you love me. Don39。t cry for me because of my death. I love you so much.（1）Where did the writer39。s mom work?
