I've celebrated Christmas many times, but this is the first time with family and relatives. My cousins from my mum's side invited us for Christmas celebration at their house this year. I don't see them often, as generally we're not that close to them. A bit history of them here. They were the children of my second uncle. He had two wives. The cousins I met there were from both. Four daughters and a son from the first, and two sons from the second. The rest were not around. The house we went to is in Tropicana, which was extremely large. I enjoyed the celebration we had yesterday. It's the usual stuff I've seen on TV, and heard from friends who celebrate them. Caroling (圣颂歌), having dinner, social talks, introduction of who is whose children etc., and not to miss, the food, delicious. I like the turkey sandwich. As usual, I looked and walked around after dinner, and to my surprise, two of my nephews, aged 22 and 25, look really beautiful, just like movie stars. The nieces were not bad at all. Some are very pretty, and the rest are all above average. We left about 11:30 pm. I sure hope to meet them again in the near future. Hopeful]y when rny cousin that I meet quite regularly, had her open house, also in Tropicana. | ||||||||||||

David's got a text message from his friend Sam. Can you understand it? 7,15 20,15 20,8,5 16,1,18,11 This message was in code (密码, 代码). How many letters are there in the English alphabet? Twenty-six. So can you read it now?
B instead of C, and so on. His message to Sam shown on the right was very short. Can you understand?
she felt puzzled. She couldn't read it at all. But David was very happy that his sister couldn't read his message! Lots of people use codes to send secret messages. In a war, secrets are very important so soldiers often send each other messages in code. Nowadays, we can use computers to make and break difficult codes. Even before computers, people invented other machines to do this. Here's a famous machine that Germans used in the Second World War (1941-1945). It's called the Enigma Machine. The machines were very big, heavy and expensive. Every day they changed the codes automatically, and this made it almost impossible for anyone to break the codes. The person sending a message had one machine, and the person receiving the message had another. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
