单选题Since then, Cash has focused her practice on video -game and Internet addiction, treating patients who use their electronic media so obsessively that they stop sleeping and eating properly, ruin relationships with loved ones, suffer repetitive use injuries such as eye strain and carpal tunnel syndrome, and develop depression and anxiety, among other things. Cash's private practice is located in Redmond, Wash. , the home of Microsoft--not an entirely surprising hub of compulsive Internet and video- game use, she says. Indeed, the Seattle--Tacoma area is the nation's 13th largest media market, and has the highest level of Internet use in the country; according to a recent study, more than 45% of adults in the area regularly play video games. "There 's nothing wrong with this technology," says Cash, who is careful to note that it's not the medium that is to blame, but rather, the lack of education about it. "It's all in how it's used" Which of the following is not a symptom of video - game and Internet addiction according to Cash?A. The stop of sleeping and eating properly.B. The suffer from repetitive use injuries.C. The ruin of relationships with loved ones.D. Insomnia and other health problems.

单选题 Look After Your Voice Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in you mouth. First gently bite the edges of your tongue with your teeth. Or press your entire tongue to the bottom of your mouth and hold it there until the saliva flow. Or you can imagine that you are slicing a big juicy lemon and sucking the juice. Before you begin your talk, be kind to your voice. Avoid milk or creamy drinks which coat your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice. If you sense that you are losing your voice, stop talking completely. Save your voice for your speech. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If you need to see a doctor, perhaps you can get some advice from a professional singer. In the meantime, do not even talk in a low voice. What about drinking alcohol to wet your throat? I advise you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking. Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a life-time. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said, "We learn to skate in the summer and swim in the winter. Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body."

单选题Eating Potatoes Gives Your Immune System a Boost Eating potatoes is not only good for bowel health, but also for the whole immune system, especially when they come in the form of a potato salad or eaten cold. In a study on an animal model, researchers in Spain found that pigs fed large quantities of raw potato starch (RPS) not only had a healthier bowel, but also decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation or disease, generally when the body is challenged. The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect, a generally more healthy body. The reduction in leucocyte levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation, but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising. In what was the longest study of its kind, pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. "The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch," said study leader Jose Francisco Perez at the Universitat Autonoma de Barcelona, Spain. Humans do not eat raw potatoes, but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10 percent of the starch eaten by human is resistant starch—starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS). Immunology expert Lena Ohman"s team previously found that the overall lymphocyte levels do not vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of IBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet of resistant starch may be worth trying in IBS patients. Ohman is currently at the Department of Internal Medicine, Goteborg University, Sweden. The study is published in the journal Chemistry and Industry, the magazine of the SCI.

单选题Dogs are social animals and without proper training, they will behave like wild animals. They will spoil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is that we learn to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting. One of the best things you can do for your dog and yourself is to obedience train (驯服) it. Obedience training doesn't solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of "come here, sit," it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the dog pack (群) by using extreme measures. You can teach your dog its subordinate (从属的) role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge. Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.
