我的DOS之路正是从这本书开始的，昨天看的。
1995年，还不知是96年开始学电脑（高中），当然第一次看到并接触到电脑，以前甚至没听说过电脑（好像，记不太清了）！当时（高中三年）总共学过大概20小时的电脑。是DOS操作系统，什么版本，记不得了。学过之后，几乎不知道电脑干什么用的，除了用键盘打字，在电脑屏幕上显示字。（接受事物迟钝还是怎么回事？累加起来学大概20小时呢！）
大学四年，第一年（1998年9月）学电脑基础，上机练习的时候，一开始使用也是DOS（好像也装了win98）（我们的电脑基础课的教材好像没提到win9x操作系统，后来补发了一本win95的使用手册。仍然对电脑不懂，不知是个什么东西。倒是看到同学从高年级同学那边学会了怎么找到超级玛丽玩。由于我害怕向别人请教，结果没会玩，上机的时候就瞎捣鼓。
大二学VF（那个时候学校机房普遍使用windows9x系统了，了解了一点点win98的使用。），学完后只认识桌面上的快捷图标，不知用这个干什么，怎么用。（当时学习这个很不认真，或者自己大脑迟钝 呵呵）这年开始上网，渐渐使用电脑多起来了。周围有几个同学买了电脑。就在大学的前两年里，我也偶尔努力去多学点电脑的，还买了一本dos教材。看不下去，不知怎么回事。不过总的使用电脑的时间平均每三天使用1小时。
大三，上网之后，几乎淡忘了dos。会用电脑的word写作业，拿到文印室打印出来。浏览网页、上网聊天，下载书籍阅读、bbs发帖子等等。除此之外，看到电脑很恐惧。到此，我学过了跟电脑有关的另两门课，《管理信息系统分析与设计》、《电子商务》。
大四，上网更频繁，但使用没有超出以前的能力，最多更娴熟一点。说不出电脑的abc。大概这年或更前些时间，有个在中学做会计的亲戚家买了电脑，向我问一些word、excel等的问题，茫茫然答不出。这年接触电脑的时间大概是以前的总和。在这段时间脑子里偶尔也朦胧意识到以前学的还有点印象的dos操作系统命令（比如dir、copy）的用处。
工作以后，在03年买了电脑。稍微主动的了解电脑，看了些电脑的科普书。对电脑的构成和工作原理有了大学一年级的电脑基础课要求我们理解的程度。也学会使用好些应用软件。
有了自己的电脑，立刻电脑的问题多了，特别是装操作系统的问题。在没有任何人的指导下，在装过操作系统的电脑上，我已经装过三次操作系统（一次win2k，两次winxp）。正是昨天，萌发要更娴熟的装操作系统的念头，在网上找到几篇指导装操作系统的文章，提到了dos，就又找dos的文章，结果找到了洪恩在线的这本教材。重新练习练习基本的命令，很有趣。
从今天起，更多的学习使用dos。学习万岁！
My journey with DOS started right from this book, which I read yesterday.
In 1995, or maybe starting in 1996, I began to learn about computers (during high school). Of course, it was the first time I saw and came into contact with a computer; before that, I had never even heard of a computer (well, that seems to be the case, I can't remember clearly)! At that time (during the three years of high school), I had learned about 20 hours of computer in total. It was the DOS operating system, but I can't remember what version it was. After learning, I almost didn't know what the computer was used for, except for typing on the keyboard and displaying words on the computer screen. (Was I slow to accept things or something? Adding up, I learned about 20 hours!)
During the four years of college, in the first year (September 1998), I studied computer basics. When practicing on the computer, I started using DOS first (and it seemed that win98 was also installed). (The textbook for our computer basics course didn't seem to mention the win9x operating system, and later a manual for using win95 was issued. I still didn't understand the computer, didn't know what it was. Instead, I saw that classmates learned from senior students how to find Super Mario to play. Because I was afraid to ask others for help, I didn't learn to play it, and during the computer practice, I just fiddled around randomly.
In the second year of college, I studied VF. At that time, the computer labs in the school generally used the windows9x system, and I learned a little about the use of win98. After learning, I only recognized the shortcut icons on the desktop, but didn't know what to do with this and how to use it. (I was very not serious when learning this at that time, or maybe my brain was slow. Hehe) This year I started to surf the Internet, and gradually used the computer more. There were a few classmates around who bought computers. Just in the first two years of college, I also occasionally tried to learn more about computers, and I also bought a DOS textbook. I couldn't read it down, didn't know why. However, the average time I used the computer was 1 hour every three days.
In the third year of college, after surfing the Internet, I almost forgot about DOS. I could use the word in the computer to do homework and take it to the printing room to print it out. I browsed web pages, chatted on the Internet, downloaded books to read, posted on BBS and so on. Besides that, I was afraid of the computer. Up to this point, I had taken two other courses related to computers, "Analysis and Design of Management Information Systems" and "Electronic Commerce".
In the fourth year of college, I surfed the Internet more frequently, but my use didn't exceed the previous ability, at most I became more proficient. I couldn't even say the ABCs of the computer. Probably in this year or a little earlier, a relative's family who worked as an accountant in a middle school bought a computer and asked me some questions about word, excel and so on, and I was at a loss and couldn't answer. In this period, the time I contacted the computer was probably the sum of the previous times. In this period, occasionally in my mind I vaguely realized that there were some uses of the DOS operating system commands I had learned before, such as dir, copy.
After working, in 2003, I bought a computer. I took the initiative to understand the computer a little more and read some popular science books about computers. I had the understanding of the composition and working principle of the computer that was required for the computer basics course in the first year of college. I also learned to use many application software.
After having my own computer, immediately there were more problems with the computer, especially the problem of installing the operating system. Without any guidance from anyone, on the computer where the operating system had been installed, I had already installed the operating system three times (once win2k, twice winxp). It was exactly yesterday that the idea of being more proficient in installing the operating system came to me. I found several articles guiding the installation of the operating system on the Internet, and it mentioned DOS, so I looked for articles about DOS again, and as a result, I found this textbook from Hong En Online. I practiced the basic commands again, and it was very interesting.
From today on, I will learn to use DOS more. Long live learning!
