Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends. My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him. He seemed unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard. On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical （挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around？ What had held him back before？ The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.

D In the 1960s, people asked about your astrological sign（星相). In the 1990s, they wanted to know your website （网址). These days, having a web address is almost as important as a street address. Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of free services and all it takes is some time and creativity. Think of your home page as the starting point of your website. Like the table of contents of a book or a magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it. While web pages vary greatly in their design and content, most use a traditional magazine layout （版面设计). At the top of the page is a banner（大标题) GRAPHIC. Next comes a greeting and a short description of the site. Pictures, texts, and links to other websites follow. Before you start building your site, do some planning. Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site. Draw a rough layout on a sheet of paper. While there are no rules you have to follow, there are a few things to keep in mind: Start simply If you are too ambitious （雄心勃勃的) at the beginning, you may never get the site off the ground. You can always add to your site. Less is better Most people don't like to read a lot of text online. Break it into small pieces. Smaller is better Most people connect to the Internet with a modem （调制解调器). Since it can take a long time to download large image files, keep the file sizes small. Have the rights Don't put any material on your site unless you are sure you can do it legally （合法地). Learn the Net's Copyright Article for more about this. Now it's time to roll up your sleeves and start building. Learning the Net Communities provides tools to help you build your site.
