“I can’t concentrate.” “My mind wanders when I try to study.” Lack of concentration is one of the most common complaints heard at school. We all have the ability to concentrate. Think of the times when you were attracted to a super novel or the times when you were playing your guitar or piano. But at other times your mind races from one thing to another. Here are some tips. Rest from time to time. Remember to take short breaks. Lectures are usually 50 minutes long, and that’s about the length of time most people can direct their attention to one task. But that’s just an average. Your concentration time might be shorter (20-35 minutes) or longer (perhaps 90 minutes).When you take a break, you get more oxygen to your brain! When we sit for long periods, blood tends to be pooled in our lower body and legs. Get up and walk around the room for a couple of minutes. As a result, more oxygen is carried to the brain and you can concentrate better. _______________If you study one subject for a long time, you may find it hard to concentrate. Many students improve their concentration by changing one subject to another every one to two hours. In this way you can pay more attention to something that’s different. Reward yourself. Give yourself a reward when you’ve completed a task. The task might be small, such as staying with a difficult paper until you’ve finished. But giving yourself a reward can help you be more interested in doing other tasks. Increase your activity level. Your concentration wanders more easily if you just read an article straight through. Instead, take the heading for each part and turn it into a question. For this part, that would be, “How can I increase my activity level while studying?” Then study that part to answer that question. Do this routinely. The questions give us a focus for each part and increase our involvement(参与). 小题1:According to Paragraph 3, what’s the purpose of walking around? A．To help us stay fit. B．To benefit our lower body. C．To provide the brain with more oxygen. D．To increase our concentration time to 90 minutes. 小题2:What’s the best title for Paragraph 4? A．Study for one hour each time. B．Do something difficult. C．Study in different ways. D．Change subjects. 小题3:In the last paragraph, the writer suggests that______. A．we just read the heading of some articles B．we do our best to read an article straight through C．we ask ourselves questions about what we are reading D．we ask other people questions about the article we are reading 小题4:The writer wrote the passage to______. A．encourage us to try to concentrate B．teach us how to concentrate while studying C．give us the reasons for a lack of concentration D．list the benefits we can get from concentration
