People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.These two special days are celebrated in many different ways. On Mother’s Day people wear carnations (康乃馨). A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery (墓地). These days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is" the thought that counts". Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays. Which of the following is NOT the celebration of the two special days（）

The last two years of learning has been a hard test for me. By hard work I have managed to learn enough to use computers fairly well, and to work with people who know a great deal more than I. Since I have learned all this at such personal cost, I would like to share my know-ledge with others. More and more people want to know about computers, and want to know quickly.The best way to learn is to take a course. However, many people do not have the time for this. They will have to find some other ways to get some basic information. I hope to be able to help them by writing about some of the things I have learned by myself.I have a home computer on which I’ve learned in my own time. I have used it like a home study course. I have sat down with it day after day, night after night. I have forced it to give up some of its secrets. Now I can use it to do some of the work that I get paid for. And I can do this work in my own home, instead of in an office. Many people may soon be working in a computer at home, just as many now take in other people’s typing.Some things about computers are easier than you may fear. First, computers are logical. Things that at first seem difficult will make sense to you after you learn the rules. Second, it is really not hard to learn enough to use today’s machines. You do not need to be a great brain. But you do have to learn to think in new ways. And you do have to keep a good bit of information in your head. Finally, there are many people around who are really enthusiastic (热心的) about computers. These people are always happy to be of help. The purpose of the passage is to convince readers that, by studying computers at home, people can become（）
