Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent tooth grow in its place. But if a permanent tooth falls out, that's a problem. There isn't another one under the gum that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out-or need to be pulled-an older person might need dentures. Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth. Dentures can cause pains at first and take little time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked in denture solution when not in the mouth. Dentures are important for older folks because, without teeth, it's hard to smile, talk, and eat properly. But it can be a little _ if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won't have any teeth. Try not to make fun of the person because this could cause hurt feelings. People usually lose their permanent teeth due to periodontal disease, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren't strong and healthy, so teeth can get loose and fall out. Older people often have many cavities that have been filled over the years, and these fillings can weaken over time, leading to more tooth decay. If one of your baby teeth falls out, you_. A) should have a false tooth fixed in its place B) have to put it under your pillow at once C) will gain a permanent tooth in future D) can exchange it for some money

After years of hearing drivers complain about scratches on their cars, Japan's Nissan Motor Company has officially announced the next big thing---a paint that not only resists scratches and scrapes, but actually repairs itself within a few days. The new material, developed by Nippon Paint Company, contains an elastic rubbery-like resin that is able to heal minor marks caused by car wash equipment, parking lot encounters, road debris or even on-purpose destruction. The automaker admits its results vary depending on the temperature and the depth of the damage, but adds this is the only paint like it in the world, and tests prove it works. Minor scratches, the most common type, are said to slowly fade over about a week. And once they're gone, there is no trace that they were ever there. The special paint is said to last for at least three years after it is first applied, but there is no word yet on whether more can be added after that period. Nissan claims car washes are the worst offenders for this type of damage, accounting for at least 80 percent of all incidents. But the complete auto-healing won't come without scratching your wallet. The vehicle maker notes the special paint adds about $ 100 U.S. to the price of a car. It plans to use its new chemical mixture only on its X - Trail SUVs in Japan for now, as it looks for a more widespread presentation. And while plans to offer the feature overseas haven't been made yet, if it's a hit there, you can be almost sure market forces will drive it to these shores, as well. The paint used on cars can _ . A) last 3 years before it is re-applied again B) fade only in a few days C) help to protect cars from minor paint damage D) reduce car scrape incidents to 20 percent

The Chinese-born American architect Ieoh Ming Pei is one of the most creative architects of our times. He has incorporated both eastern and western ideas into his designs. Ieoh Ming Pei was born in Guangzhou, China on April 26, 1917. His father was a famous banker. In 1935, at the age of 17, he came to the United States to study architecture at Massachusetts Institute of Technology. In 1942, he entered the Harvard Graduate School of Design. In 1964, Jacqueline Kennedy selected Pei to design the Kennedy library. After that he became well-known all over the world. People named it one of the Ten Best Buildings in the United States. In 1968, Pei started work on the East Wing of the National Gallery of Art, in Washington D.C. Over one million people visited the building during its first 50 days in existence. Following the East Wing project Pei's fame has continued to grow widely. In 1983, French President commissioned Pei to help make the Louvre more modern. Ten years later, the completion of Pei's glass pyramid at the Louvre created a new historic landmark for Paris. Pei described it as, "the greatest challenge and greatest accomplishment of my career." At Fragrant Hill, a 300-room hotel in the Chinese capital, Pei has attempted to bring to his native China his often-quoted "third way of making buildings." Avoiding both a complete copying of traditional Chinese motifs as well as the modernism of the West, Pei has managed, at Fragrant Hill, to make one of his most eloquent statements. Pei has designed nearly 50 projects in the United States and abroad. About half of these projects have won major awards. Pei has been awarded the highest honors from nations over the world. In 1990, Pei was awarded the Medal of Freedom by President George Bush for his contributions to world peace and service to the US government. _ is an excellent building that shows both the traditional Chinese motifs and the modernism of the West. A) The East Wing of the National Gallery of Art B) Pei's glass pyramid at the Louvre C) Fragrant Hill D) Kennedy library
