Your smartphone(智能手机) can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little device（设备）of yours – it might also spread disease.

    “People are just as likely to get sick from their phones as from handles of the bathroom,” Jeffrey Cain, the president of the American Academy of Family Physicians, told The Wall Street Journal.

    This may be hard to believe, but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms(大肠菌), a kind of bacteria found in excrement(粪便)，with about 2,700 to 4,200 units of the bacteria on each phone. In drinking water, the healthy limit is less than 1 unit per 100 ml of water. This bacteria can cause flu, pinkeye（红眼病）and diarrhea(腹泻).

    Although computers, keys and pens all carry germs(细菌), our smartphones get far dirtier. They touch a lot of stuff, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn't played Angry Birds of Fruit Ninja while sitting on the toilet?

    “Some things that we think are personal are actually more public than we imagine,” Cain said.

    What's even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don't think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease（油脂）, an environment that germs really like.

    Compared to traditional keypads（键盘）, touch screens transmit（传播）germs more easily to hands. According to Time magazine's website, an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.

    So how do you keep your smartphone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone's surface: wash your hands regularly.

    Imagine you are in a jumping contest. Animals and insects can also enter this contest. But they might just leave humans in the dust!

    The first event is the long jump. The human athlete is Mike Powell. In 1991, he jumped nearly 30 feet, which is the world record for the long jump. That is about five times his own height.

    His competitor in the long-jump contest is a frog named “Rosie the Ribbiter.” Rosie set the world record for frogs in 1986 by jumping more than 21 feet. Her record has never been broken by any other frog. Compared to Mike Powell, Rosie's jump is not that amazing. But wait! Rosie is only about 10 inches long when her legs are stretched to their full length. She can jump more than 25 times her size. Rosie, the frog, wins the long-jump event.

    The next event is the high jump. Javier Sotomayor, the world record holder, can jump a bar (横杆) 8 feet high. That is about as high as the ceiling in most homes.

    Looking around for someone to challenge his record, Javier might need a magnifying glass (放大镜). The next contestant is a tiny insect called the spittlebug (吹沫虫).

    The spittlebug can jump 28 inches into the air. It is only a quarter-inch long, less than the width of a pencil. If the spittlebug were the same size as Javier, it would be able to jump 600 feet into the air. That is like a human jumping over a building 55 stories high!

    Though the humans lose the “jumping contest,” their competitors would probably agree that Mike and Javier are still pretty excellent athletes. If only Rosie and the spittlebug could speak!

    Paparazzi, (狗仔队)or “paps”, are photographers who take pictures of famous people when they are not at the center of public attention. Paps are different from professional photographers or journalists because they never take ordinary photos.

    The goal for paparazzi is to get pictures that no one else will get and then sell the pictures to the buyer who offers the most money — normainly a small newspaper, magazine or website.

    There is no law against paparazzi taking pictures in public places. However, there are laws that protect certain individuals. For example, child protection laws stop improper pictures of anyone under 16 from being published.

    There is also no law that stops paparazzi from following celebrities（名人） and taking their pictures either. However, if paps are secretly following them and taking pictures of their faces, they could get into trouble.

    Most paparazzi hang out on streets and hot spots for celebrities, waiting for the opportunity to take a picture of a star. Many stay on the streets until the early hours of the morning when celebrities are leaving nightclubs and looking a little worse for wear. However, some have other ways to make sure they get pictures. Many paps are in contact with “informers” who know the locations of celebrities at any given time. They then pass the information on to paparazzi. An informer could be anyone — from a restaurant waiter to a salesman.

    Most of the time, paparazzi get a bad reputation for following celebrities. But sometimes stars or their managers will contact paps themselves and tell them exactly where and when they will go. What a love-hate relationship between paparazzi and celebrities!

    The Hawaii Volcanoes National Park

    The Hawaii Volcanoes National Park, on the island of Hawaii, has two active volcanoes: Mauna Loa, which last erupted (喷发) in 1984, is 13,677 feet (4.17 km) above sea level; Kilauea is next to Mauna Loa and it has been erupting since January 3rd, 1983. It is 4,190 feet (1.23 km) above sea level.

    When to visit

    The park is open 24 hours a day all year round. There are no plants or trees on the lava (火山岩) fields and no protection from the sun, so you must bring sunscreen (防晒霜).

    How to get there

    The best way to get to the park is to take Highway 11. From the airport at Hilo, Highway 11 will take you southward across the eastern part of the island.

    Things to see

    If you want to know more about the park, the Kilauea Visitor Center is surely a stop to make. It is a quarter of a mile (402 m) from the park entrance. There, you can see a great movie about real lava and learn about the island's natural and cultural history. The center is open from 7:45 a.m. to 5:00 p.m. There are also many guided walks and hikes around the park. You must check weather conditions and volcanic activity before hiking alone. If possible, you may drive down Chain of Craters Road to see lava flowing into the ocean.

    Tickets

    Entrance to the park is $10.00 for each vehicle, $5.00 for those who travel on foot or ride a bicycle. Children under the age of 15 are free.

    If you have the opportunity to visit some places in New Zealand, then the list below is our recommendation.

    Fiordland National Park

    This park is part of the South Westland World Heritage Area and is New Zealand's largest national park and one of the largest in the world. The scenery in Fiordland is nothing short of extremely beautiful, with steep mountains, wild waterfalls, and abundant rain forests. Being able to come back and forth in its deep bay attracts most of the visitors.

    The area has some of the world's greatest walks including the world famous Milford Track, which was described as the finest walk in the world in the early twentieth century.

    Abel Tasman National Park

    Abel Tasman may be New Zealand's smallest national park, but the attractions are huge. Located in one of New Zealand's sunniest spots, the area also has the best beaches in the country.

    The popular Abel Tasman Walk is a great way to see this park. It takes 3-5 days to complete. Sea taxis are also available and can drop you off at any number of beaches within the park.

    Rotorua

    Accessible from New Zealand's biggest city, Auckland, Rotorua is famous for its volcanic activities. Rotorua is also famous for its plentiful lakes which are great for swimming and fishing. The surrounding area contains plenty of native bushes and some famous walks.

    Rotorua is also the best area in the country to experience and learn about Maori culture.

    Mt Cook National Park

    Mt Cook as well as the surrounding area is an alpine( 高山的) park within the World Heritage listed in South Westland. The biggest peaks in all of Australasia are here. The park doesn't contain many trees or plants due to the altitude. Walks range from a two-hour walk to difficult tracks suitable for experienced mountaineers only.

    A helicopter or plane ride gives visitors excellent views of the mountains with the option of landing at the top of Tasman Glacier, a true permanent snow-covered alpine environment.
