I'm 14, a year younger than most of my classmates. A week ago one of my classmates, Nitin, asked me for help with math homework. We ended up talking about computers and file-sharing . As we talked I found that he was more experienced and could teach me about file-sharing and networking. We went to his room and watched a movie about robots that he'd downloaded. The math homework was forgotten. The next day he came again for homework help "What do you do on weekends?" he asked. The truth is, when I have work to do, I do it. I have no special time to with friends. I was embarrassed about this. I expected him to think I was boring and said, "Get a life!" He said, "OK. You're having trouble getting along with people I can show you. I'm old than you." Later, he checked my computer. He even connected me to an Internet chess server .He was becoming like a big brother. But when I thought about it, I didn't really want Nitin's help" His big-brother idea began to bore me. "I'll get you some cool computer programs ". "I'll teach you how to talk to girls." He meant what he was saying, but I don't know why it didn't make me feel good. Since then he's hardly talked to me; we seem to have forgotten each other. I don't think he can "teach" me much, and I don't think much of him. But I could be wrong* Can you use a word to describe the writer? A) Unfriendly. B) Boring. C) Independent. D) Lazy.

Many college students have given up taking class notes by hand. Instead, they type on computers. But scientists say that method is less helpful. If you need to remember something, write it. Writing notes by hand is much better for long-term memory of idea. So, turn off your computer if you want to remember something. Students who type notes on a keyboard often write down what the teacher says word-for-word. They may write without really thinking about what they are writing. These electronic notes contained more words. But scientists say it leads to " _ ." Transcription means to write down something exactly as you hear it. However, students taking notes by writing them, need to first process the information they hear. Then they record just the main parts. They use fewer words. This is because people usually write slower than they type. This kind of process leads to a deeper understanding. The scientists did a research. In the research, students listened to a teacher and then took a test. Some took notes by typing on a computer. The others took notes by writing them down. Both groups performed about the same in remembering facts. But students who typed their notes did much worse on conceptual questions. These questions required them to understand an idea. Also, scientists found that those who wrote their notes remembered conceptual information better a week later. Scientists believe that the students who took notes by writing them had a deeper understanding of ideas. Scientists know that students probably will still use their computers in class. But they suggest to take notes by hand on screens. They say this might be a good way between different schools. According to the research, college students usually use few words to take notes by hand in class because they _ . A) are very lazy B) want to write fast C) are all clever D) dislike to take notes
