What's your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to explore the world.So we visit travel agents, compare packages and prices, and pay our money.

    We know what our vacation costs us.But do we know what it might cost someone else?It's true that many poorer countries now depend on tourism for foreign income.Unfortunately,though.tourism often harms the local people more than it helps them

    It might cost their homes and lands.In Myanmar.5.200 people were forced to leave their homes among the pagodas(佛塔）in Bagan so that tourists could visit the pagodas.

    Tourism might also cost the local people their livelihood（生计）and dignity（尊严）.Local workers often find only jobs with slim salaries in the tourist industry.And most of the profits（利润）do not help the local economy. Instead,profits return to the tour operators in wealthier countries,When the Maasai people in Tanzania were driven（驱赶）from their lands,some moved to city slums.Others now make a little money selling souvenirs or posing(摆姿势）for photos.

    Problems like these were observed more than 20 years ago.But now some non-government organizations,tour operators and local governments are working together to begin correcting them.Tourists,too,are putting on the pressure.

    The result is responsible tourism,or ethical tourism.Ethical tourism has people at its heart.New international agreements and codes of conduct（行为准则）can help protect the people's lands homes,economies and cultures.The beginnings are small,though,and the problems are complex.

    But take heart. The good news is that everyone,including us,can play a part to help the local people in the places we visit Tour operators and companies can help by making sure that local people work in good conditions and earn reasonable wages.

    They can make it a point to use only locally owned hotel restaurants and guide services.They can share profits fairly to help the local economy And they can involve the local people in planning and managing tourism.

    What can tourists do? First, we can ask tour companies to provide information about the conditions of local citizens.We can then make our choices and tell them why. And while we're abroad, we can: Buy local foods and products, not imported ones.

    Pay a fair price for goods and services and not bargain for the cheapest price.

    Avoid flaunting wealth.

    Ask before talking photographs of people.They are not just part of the landscape!

    Let's enjoy our vacation and make sure others do,too.

    Food festivals around the world

    Stilton Cheese Rolling

    May Day is a traditional day for celebrations,but the 2,000 English villagers of Stilton must be the only people in the world who include cheese rolling in their annual plans.Teams of four,dressed in a variety of strange and funny clothes,roll a complete cheese along a 50-metre course.On the way,they must not lack or throw their cheese,or go into their competitors' lane.Competition is fierce and the chief prize is a complete Stilton cheese weighing about four kilos (disappointingly,but understandably the cheeses used in the race are wooden ones).All the competitors are served with beer or port wine,the traditional accompaniment for Stilton cheese.

    Fiery Foods Festival—The Hottest Festival on Earth

    Every year more than 10,000 people head for the city of Albuquerque,New Mexico.They come from as far away as Australia,the Caribbean and China,but they all share a common addiction—food that is not just spicy,but hot enough to make your mouth bum,your head spin and your eyes water.Their destination is the Fiery Food and BBQ Festival which is held over a period of three days every March.You might like to try a chocolate-covered habanero pepper—officially the hottest pepper in the world—or any one of the thousands of products that are on show.But one thing's for sure—if you don't like the feeling of a burning tongue,this festival isn't for you!

    La Tomatina—The World's Biggest Food Fight

    On the last Wednesday of every August,the Spanish town of Bunol hosts La Tomatina—the world's largest food fight.A week-long celebration leads up to an exciting tomato battle as the highlight of the week's events.The early morning sees the arrival of large trucks with tomatoes—official fight-starters get things going by casting tomatoes at the crowd.

    The battle lasts little more than half an hour,in which time around 50,000 kilograms of tomatoes have been thrown at anyone or anything that moves,runs,or fights back.Then everyone heads down to the river to make friends again—and fora much-needed wash!

    A day in the life of 18-year-old David Lanster is full if typical teenage stuff: school, baseball practice and homework. And then he starts cooking. “Some nights I'm up until 1:00 a.m. making pies, or even later if we're cooking beef,” said the student at Ransom Everglades High School in Florida, US.

    For the past year, Lanster and Kelly Moran, his classmate, have been hosting fancy dinner parties at Lanster's parents' home. Their meals have 17 courses and are all made by them. Their guests used to give them gifts to thank them until the pair decided to do something nice for charity（慈善）. “We got some really great Miami Heat tickets, a nice watch, and many kitchen gadgets（小器具）,” Lanster said. “But we wanted to make this something positive for people other than us.”

    Lanster and Moran focused on Common Threads, a charity that aims to teach kids in poor communities to cook and make healthy eating choices. The young cooks ask their guests to give however much they want as payment for their meals. It all goes to Common Threads because Lanster's parents cover their food costs. After their last 12-person event, Lanster and Moran gave $1,600 to the charity.

    Now, they're taking their show out of the kitchen and on the road. They have started to organize private dinner parties with a similar model: the host pays for the ingredients, and the guests make a donation to a charity of their choice.

    Without formal training, Lanster said he had been interested in cooking since he helped his mom in the kitchen when he was very young. He learned how to cook by reading cookbooks and watching TV programs. Outside the kitchen, the two are busy preparing their college applications. Neither of them is sure what they will do in the future, but they're promised their parents that they will leave professional cooking alone until they finish school.

    Flying insects are polluting new environments by eating microplastics in polluted waters and carrying them through the air, a new study has found.

    UK researchers found that microplastics -- pieces of plastic less than 5 millimeters in size -- remain in the bodies of mosquitoes and other waterborne insects even after they become flying adults.

    The findings mean that pollution from plastics being dumped into our oceans is being carried into the air, and raises concerns that birds and other creatures that eat the insects are also being polluted.

    The team from the University of Reading in England and Queen's University in Belfast, Northern Ireland, inserted two minuscule pieces of polystyrene, each weighing just over one gram per cubic centimeter, into young mosquitoes and observed the insects throughout their life cycles. They found that the particles did not disappear from the mosquitoes' systems after the insects moved between life stages and started to fly, and were present inside the fully formed insects. “When the microplastics become the adults, it represents a potential aerial pathway to pollution of new environments,” the authors wrote in the study.

    “Thus, any organism that feeds on terrestrial life phases of freshwater insects could be affected by MPs found in aquatic ecosystems ( 水生态系统),” they added, using an abbreviation for microplastics. Freshwater insects such as mosquitoes are eaten by birds, amphibians, insects and fish, according to the Environmental Protection Agency in the United States. More than 150 million tons of plastic are floating in the world's oceans, with an additional eight million tons entering every year, according to the World Economic Forum. Plastic can be eaten by fish, birds and marine mammals, and can damage marine ecosystems such as coral reefs.

    “This disturbing study raises real concerns about the spread of plastic pollution: it really is present everywhere, not just the marine environment,” said plastic pollution campaigner Emma Priestland from the charity Friends of the Earth.

    “Knowing that plastic can be moved from the larval stage to the adult mosquito, which then serves as food to a multitude of larger animals, highlights the urgency with which we need to.”

    A study from 2015 estimated that the total amount of floating plastic in the oceans could triple by 2025.

Teaching Poetry

    No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it.

    All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling "interpretation" of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting it.

    I have come to think, in fact, that time spent reading a poem aloud is much more important than "analysing" it, if there isn't time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is "a criticism of life", and "a heightening of lief". It is "an approach to the truth of feeling", and it "can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies.

    I am not saying that every English teacher must teach poetry. Those who don't like it should not be forced to communicate this to anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.

    I have a story about raising free-range (自由放养) kids. This past Columbus Day, my husband and I went fishing with some friends on their boat while our10 and 8-year-old kids were in school. We left the house all at the same time, about 7 a. m. My children walked to and from school every day and we knew they would be OK for a couple hours by themselves anyway. We told them to go home after school and we would be home around 4 p. m.

    We live on the Gulf Coast, and since it was a beautiful day, all of the adults decided to go fishing off-shore. At around 2 p. m. after a good harvest from the sea, we started back to the shore and unfortunately after some time, we ran out of gas. We were out of cellphone service, and what was even worse was that 911 wasn't working. We didn't have a radio either. Therefore, we were stuck waiting for someone to pass by. We were out there until 10 p. m. All the while my children were at home, expecting us to return shortly after they got home. At about 7 p. m. , when it was getting dark, my 10-year-old daughter thought something might be wrong so she walked to each house on the street until someone answered the door and asked the person what they should do. This was how we were finally found by the game warden (管理员) on the coast and "rescued".

    Talking with that neighbor the next day, I was never so proud of my children. This neighbour explained to me, "What calmness both of your children showed when explaining the situation and how impressed I was with your children seeking help, even though they didn't know me." I never doubted him for a minute, though next time we go fishing we'll monitor the gas more carefully.
