There are always times in the day when you catch yourself clenching your teeth if you are trying to focus on something important or concentrating on something. Of course, if you are doing this in your sleep you won't be able to catch yourself and stop. The good news is that there are things you can do to help relieve the pain that is caused from bruxism and help keep your teeth healthy as well. If you wake up in the moming with sore jaws, pain in your neck and shoulders, or a persistent headache, you are more than likely to have bruxism. A lot of medical professionals think that a major aspect of bruxism is from stress. Everyday life can be filled with stressful situations and this stress gets released at night when you are sleeping. If you suffer from stress on a regular basis you can try a relaxation technique before you go to bed. The hope is that by relaxing your body and mind you will let go of the stress that will cause you to grind your teeth while you are sleeping. This routine has worked for millions of people and is a good thing to try first. While relaxation to relieve stress sounds pretty good, there are people that this technique doesn't work for. For these people, there are mouth guards that you can wear while you are sleeping that will help protect your teeth. These mouth guards will put a protective layer between your teeth in order to ease any issues that grinding your teeth may cause. If you want to get the best possible relief you should try both the relaxation techniques and a mouth guard. The mouth guard will keep your teeth from damage and the relaxation techniques will help ease the stress that your body might be feeling. Nothing can be better than relieving both pain and stress when you need it most, while you are sleeping. The reason people grind their teeth is that they _ . A) can't get a sound sleep B) are thinking of something hard to settle C) feel stressed in their daily life D) are suffering a persistent headache

School uniforms are becoming more and more popular across the U.S.A. That's no surprise,because they offer many benefits. They immediately end the powerful social sorting and labeling that come from clothing. If all students are dressed in the same way,they will not pay too much attention to their clothing,and some of them will not be laughed at for wearing the "wrong" clothes. Some people are against the strict rule of school uniforms,but they do not realize that students already accept a kind of rule -- wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers ; school uniforms tear those barriers down. As in other places,uniforms remind the wearers of their purposes and duties. For example,when a man or woman puts on a police uniform,he or she becomes,for a time,the symbol of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearer meets. People with different jobs wear uniforms of one kind or another. For students,the school uniform reminds them that their task for the six or seven hours they are in school is to get an education. Some parents are unhappy about uniforms,saying that school uniforms will affect their children's "creativity". First,as noted above,the clothes students choose to wear do not necessarily express their individuality . They just copy their classmates. Second,students have the rest of the day to be as creative as they like. While they're in school,their job is to master reading,writing,and maths; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way. Some people are against school uniforms because_. A) they fail to realize that students have accepted the uniforms B) they believe that uniforms will make students less creative C) they don't agree that uniforms can remove social barriers D) they think that school uniforms are too popular

Q: Once upon a time, there was a scholar who wanted to gain more knowledge each day even though he had already gained enough knowledge. One day, he came to visit a saint and wanted to be his student. The saint provided some tea. He slowly filled the scholar's cup: the cup was full, yet he kept pouring and pouring. The scholar burst out, "Stop! You can't add anything to something that's already full!" The saint set down the teapot and replied, "Exactly." Whether it's the silence between notes in music, or some open time in your schedule, you need space to act effectively. Yet most of us, myself included, tend to stuff as much as possible into whatever room is available-closets, schedules, budgets, relationships, and even the mind itself. However, some people know how to avoid overstuffing their life. For example, in Australia, it seemed that most people there operated at about 85% of their capacity ,unlike Americans pushing as close to 100% as possible. So when you run into Australians you know in the street, they have time to hang out and talk with you. Remember the cup: its value is in the space, the emptiness it holds. How to empty your "cup"? Be mindful of the element of space, openness , and emptiness in your life. This includes room in a drawer, the volume of air in a kitchen, and open-mindedness in a friend. Sometimes you're just stuck with a big bucket of tasks yet to do. But at least empty the bucket faster than you fill it with new tasks. Put some space between finishing one thing and staring another. For example, after sending one email, take a breath before replying to another one. Drop the stuff you can no longer afford to _ around. At sea level, you can run with a brick in your backpack, but if you're hiking on a mountain, that brick has got to go. What would be the best title for the passage? A) The art of life. B) Value every minute C) The art of drinking tea D) Empty your"cup"at times

Q: Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a _ . At first, Eijkman thought some kind of germ caused beri-beri. He raised some chickens. He didn't eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate -- refined white rice . When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery -- that some things in food could prevent disease. These things were named vitamins . The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person's food. Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don't, they can also take vitamin pills. We can learn from the passage that _ . A) beri-beri was caused by chickens B) Christian Eijkman's experiment was successful C) the Javanese didn't like vitamins D) the Javanese's disease was caused by a kind of germ
