There is no doubt that the Internet also has some bad points.I'm speaking about the harmful information,which may come up in the most unexpected paces.You can sometimes come across violence,presented to the public as a very normal way of expressing beliefs.An intelligent person will always be able to tell apart right and wrong, but what can we do to help the teenagers and children? This sort of information is a cause of many of the violent incidents in schools. There are few organization that monitor the Internet and the information on it.They cannot possibly get rid of all the bad things on the Internet. So should the Internet be censored for the protection of children? My belief is that parents are the ones who should be to blame for what their children ale doing on the Internet.

Article: New findings show that musical training affects the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity in the brain, offering an alternative tool in education, and treating a range of learning disabilities. Today's new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect. Even older adults who took music lessons as children but haven't actively played an instrument in decades have a faster brain response to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound. "Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements--from finger tapping to dancing -- and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time," said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music. "As today's findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition , and learning," he added.
Question: Why does the author mention "Even older adults ... a speech sound." in Para. 3?
Options: (A) To suggest how new roles for musical training work. (B) To prove early musical training affects the function of the brain. (C) To explain how the brain interprets sensory information. (D) To show how the brain areas communicate in music training.

Article: Writing a long book seemed to be too much for me. So, for a long time, I just wrote short articles. One day, inspiration for an article hit me and, as I started writing, paragraphs began flowing out fast. It turned out to be too long to be an article. I thought it would not hurt to try self-publishing a booklet . The first printing of this 32-page black and white booklet sold out within a week. Here is something that I have learned through my experience. 1.Start small. Don't try to have a 400-page work as your first publication. I suggest you publish a booklet under 50 pages to _ your career as an author. 2.Ask for advice. If you know some people who have published something, ask them for advice and help. You will gain useful information from them and save yourself many problems. 3. _ When you put your heart into something only to hear"We're not interested",you may get hurt. But you must remind yourself that this is quite common. Every"yes"you receive comes after at least five"noes",especially at the beginning. You need to revise your book many times to reduce the chances of being turned down. 4.The more you market, the more you sell. You can publish an excellent book. But if no people know about it, you cannot expect many buyers. Send out an e-mail to friends, family and business partners, telling them your book's publication date. Ask them to help sell your book. Do not be afraid to try novel ideas.
Question: What's the best title for Point 3?
Options: (A) No one will like what you wrote at first. (B) You will get hurt by what you wrote at first. (C) Prepare for a"yes"rather than a"no". (D) Be prepared to deal with"noes".
