People travel for a lot of reasons.Some travelers go to see battlefields or religious shrines.Others are looking for culture,or simply want to have their photos taken in front of famous places.But most Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it.Residents of cities like London,Copenhagen,and Amsterdam spend a lot of their winter in the dark because the days are so short and much of the rest of the year is in the rain.Every summer,more than 25 million people travel to Mediterranean resorts and beaches for their vacation.They all come for the same reason: sun. The huge crowds mean lots of money for the economies of Mediterranean countries.Italy's 30,000 hotels are booked every summer.And 13 million people camp out on French Beaches,parks,and roadsides.Spain's long sandy coastline attracts more people than anywhere else.37 million tourists visit yearly,or one tourist for every person living in Spain. But there are signs that the area is getting more tourism than it can handle.The Mediterranean is already one of the most polluted seas on earth.And with increased tourism,it's getting worse.The French can't figure out what to do with all the garbage left by campers around St.Tropez.And in many places,swimming is dangerous because of pollution. None of this,however,is damaging anyone's fun.The Mediterranean gets more popular every year with tourists.Obviously,they don't go there for clean water.They stand traffic jams and seem to like crowded beaches.They don't even mind the pollution.No matter how dirty the water is,the coastline still looks beautiful.And as long as the sun shines,it's still better than sitting in the cold rain in Berlin,London,or else. Which of the following will damage the tourists' fun at Mediterranean resorts and beaches? A) Polluted water. B) Crowded buses. C) Traffic jams. D) Rainy weather

Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life. Blue/Purple Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight. A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer. Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc. Green We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer. Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene . Diets high in those above are associated with lowered blood pressure." Foods that contain the green color are: broccoli, cabbage, cucumbers, etc. Red Lycopene in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks. Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce." Foods that contain red color are: Tomatoes and tomato products, watermelon,... All the colors mentioned in the passage have the function of _ . A) lowering blood pressure B) improving eyesight C) preventing cancer D) reducing the risk of heart disease

Q: LG Electronics, the world's fourth largest cell phone producer, has added another feature to the mobile phone-reading books for the visually impaired . The company started marketing the model, the LF1300 on Sep.18.No other people but the blind and visually-impaired with a certificate can buy the talking phone at sales shops of LG Electronics. "The LF1300 is the world's first mobile phone that is capable of reading books for the print-disabled, who otherwise could not enjoy them.This is not about making money but about continuing to put froth efforts to reduce the digital difference for the disabled," LG Vice President said. Its users can download about 300 audio books from the Internet site of LG Sangam Library to their phones for free in two ways. One is to access the digital library's Website on a computer designed for the blind to get the audio books and transfer them to cell phones. The other is to download the digital books directly with cell phones through the wireless net work by touching a hot key on the LF1300 phone. On top of its unique feature of reading books, the LF1300 is no worse than the pupular top-line phones in both outlooks and frnctionalities . The phone is armed with an MP3 player and a Bluetooth headset, enabling users to listen to the music or talk without a cord. The user interface of the LF1300 is also designed for the blind,enabling phone users to control it through a voice guidance system. However, because the phone's internal mimory of 17MB is small even for a single audio book file, which takes up 80MB on average, a high-volume external memory is a must for the talking book services. The users can enjoy reading books on LF1300 by _ . A) talking to the microphone B) touching any key C) touching its screen D) touching the hot key

Astronomers have captured the first direct image of a planet being born. Adam Kraus, of the University of Hawaii's Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth. The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago. Called LkCa 15b, it's the youngest planet ever observed. The previous record holder was about five times older. Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA's Goddard Space Flight Center in Maryland. Observing planets while they're forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away. Planets can change orbits after forming, so it's difficult to answer such questions by studying older planets. "These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now," Kraus said. Scientists hadn't been able to see such young planets before because the stars they're circling around outshine them. Kraus and Ireland used two techniques to overcome this problem.[:++] One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion created by the Earth's atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star. The star LkCa 15--the planet is named after its star--was the team's second target. They immediately knew they were seeing something new,... Which of the following would be the best title for the text? A) Youngest planet seen as it's forming. B) Planet 450 light years away discovered. C) World's first direct image of a planet taken. D) New technique helps discover young planets.
