It is easier to learn a language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary.

But for many senior high students, music is an important part of life. This result was found following a teen magazine's summer survey on readers' attitudes to music. Nearly 10,300 readers replied to the survey.Over half, 52 percent, said that they listen to music whenever they are free. Just 0.5 percent of students said they never listen to music. Most listen to both English and Chinese songs.But, the survey showed that students have very different tastes and enjoy a wide variety of styles. About 32 percent of students listen to Pop music. Behind Pop came R&B, Country, Rock, Hip-hop and others.Parents have the least effect on students' tastes and do not enjoy the same music. Just three percent of students listen to music that their parents introduced them to.Questions1. What was found by the teen magazine's summer survey?2.

For the first 7 questions in each passage, choose the best answer from the four choices marked A, B, C and D. For the remaining 3 questions in the same passage, complete the sentences with the information given in the passage.Questions 1 to 10 are based on the same passage or dialog.Are You Reading as Many Books as You Would Like?Do you read as much as you'd like, or as many as you'd like of the books you're interested in? Are you aware that the time spent on today's reading prevents you from reading something else? Life is one of choices?make sure your choices take you in the direction you wish to go.My biggest recommendation (建议) to increase your reading rate is to attend a rapid reading course (sometimes called speed reading), but the single most important element is the on-going practice.If you want to try a few techniques on your own, here are a few key pointers, but you really need to attend a course to bepushed to significantly higher levels of competency, because only an external person can push you past the comfort zone of your eyes, your brain, and your current beliefs about your abilities.Some Rapid-reading Keys:Read with purpose. Don't read things you won't remember, and don't waste time reading things that won't further you in any way. However, many people read mindlessly, just because it's there! You should start with the end in mind.Have an expectation of success. See yourself reading at great speed.Fill your mind with a positive expectation of great deeds. Feel and imagine the power of the rapid flow of information into your mind. And hear the rapid flow of words just pouring into your brain.Preview and review the book. You can do it by scanning contents andother information at the front, as well as the back. Sit upright andhold the book at a comfortable position. Have good overhead light, fresh air, plenty of water, and a comfortable temperature.Use a visual guide. You may usually use your finger, or sometimes two fingers, which depends on the size of the print. This is where the training by an instructor is really useful (they won't let you get away with bad habits, and they push you beyond your comfort level). One ofthe key elements of rapid reading is to use our finger at a very fast rate, running it down the page. We don't need to read every word inorder to comprehend (理解) and keep the information. All weneed is a large amount of text, and the sense is gathered at lightening speed.Speed training. Go as fast as your hand can turn the pages, and don't worry that there seems to be practically no comprehension at this stage. The key is to extend the eye's capacity to absorb, and to strengthenyour mind's belief that it can be done. Two hands are needed. With one hand run a finger down the page as fast as you can. At first you'll notice an occasional word or phrase will jump out at you, but not much else. That's fine—comprehension is not the goal at this stage. With the other hand, turn the pages as fast as you can go.Set a daily target for yourself—it might be to race through a thick book that you're interested to read. It might be to practice for a specified amount of time.Practice, practice, and practice. Magazines and newspapers are great to practice on. The columns (栏目) are thin, which helps you go even faster.Comprehension. You may think you're not absorbing much, but try this test. Choose a book you want to read. Each time you pick it up to readin your old style, first do the rapid run described above. You'll notice when you come to read in your slow way that in fact you already know,and can remember having seen, most of the key concepts. We call this a conscious convincer. Your subconscious needs reassurance (安心) that nothing is being lost, and that you have absorbed the information you need. Coupled with the rapid "preview", if you do wish to read slower,do it with a highlighter in your hand. Your ability to keep thematerial will be greatly enhanced, for you will have visited the information several times.You may still wish to read at a slower speed for enjoyment, or because you need to really absorb every word of an author for study purposes,but if every day you practice this technique, suddenly you'll find you really are reading and absorbing at a much faster rate.1.
