In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about half a dozen becomes the strong, circling winds of 75 miles per hour or more that are called hurricanes, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people. The great storms that hit the coast start as soft circling wind hundreds -- even thousands -- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the southeast winds. When conditions are just right, warm, moist air flows in at the bottom of such a wind, moves upward through it and comes out at the top. In the process , the moisture in this warm air produces rain, and with it the heat is changed to energy in the form of strong winds. As the heat increases, the young hurricane begins to move in a counter-clockwise motion . The life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours, causing sudden floods. Worst of all is the powerful movement of the sea -- the mountains of water moving toward the hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore. Here the word "downpour" means _ . A) heavy rainfall B) dangerous waves C) the progress of water to the hurricane center D) the increasing heat

Q: 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. A person wearing dentures_. A) should brush them with a special denture brush every few days B) will take a very long time to adjust himself or herself to them C) will experience unpleasant feelings at the beginning of fixing them D) should use denture solution to soak them in his or her mouth

*Question*
If you want to avoid making impulse and unnecessary purchases,then just keep your hands away from tempting products. According to new research,individuals who touch possible items in stores are more likely to have an increased desire to purchase them than those who keep their hands off the products. Suzanne Shu and Joann Peck,marketing professors at the University of Wisconsin's business school conducted studies on the connection between touch and feelings of ownership and the effect of perceived ownership on the value placed on an object. For one of the experiments,the experts placed two products,a Slinky toy and a coffee mug in front of the volunteers who were undergraduate students. About half of the participants were allowed to touch the products,while the other half were asked not to touch them. The volunteers then were asked to express their sense of ownership of the products and to report how much money they were willing to pay for each. The results showed that those students who were allowed to touch the objects,reported significant increased levels of perceived ownership. They also expressed a desire to pay more money to obtain the products. The investigators also discovered that a sense of very pleasant feelings when touching products,determined how much money consumers were willing to pay. However,if the object did not feel pleasant to the touch,it significantly decreased the amount the buyers were willing to pay. Researchers said that many stores have already followed the right path. But what can be done while shopping online,when touching of an item is not possible? In this case,the experts say,just picturing in mind that they are touching it and then owning it,will cause greater feelings of ownership,and thus the consumers will be more likely to make a purchase. When you touch an object,you immediately feel some kind of a connection to it,according to the researchers. That connection stirs up an emotional reaction. And that emotion can make people buy something they would never even... The author develops the text mainly by _ .
