In many countries of the world, people do what is called housesitting．It means that if owners of the house are going away, they wantsomeone to come into their home and look after the house and maybe pets whilethey are away．

        In Australia, many people travel．After peopleretire, they might buy a van and travel all over the country．{#blank#}1{#/blank#}．

        So if someone wants to travel or go away for some reason, theymight want someone in their home to care for it and keep the gardens tidy．House sittersmight have to care for pets．Also, quite afew people have swimming pools in their back yard and they need cleaning．{#blank#}2{#/blank#}． I feel it isa great way of seeing the country, because you go and stay in a new city, getto meet new people, and have time to go sightseeing in a new area．

{#blank#}3{#/blank#}．There arewebsites where you find the advertisements by people who want to travel, and byreplying to the advertisement, you can make arrangements to go and look aftertheir home．

        There are some requirements to be a house sitter．You must be atrusted person, so that the home owner knows you will not steal anything．You must beable to go when the house owner wants you to go, so you need lots of free time．{#blank#}4{#/blank#}．You need to begood with pets, able to care for cats and dogs, or other pets they may have．

        Some house sitting jobs are just for a few days or a couple ofweeks while the house owners have a short holiday．Sometimes itis for much longer．We have hadone house sit for six months, while the home owner travelled to Europe．

{#blank#}5{#/blank#} Then you can travel to many differentcountries and stay there．One of theimportant things to get is references from the home owners where you havestayed． A reference is a written letter to say that you are trustworthyand have looked after their home well．You can showthese letters to possible house sitting jobs and they know you will do a goodjob．

A．I have donehouse sitting many times．

B．Thousands ofpeople do this all the time．

C．It is alsopossible to do house sitting in other countries．

D．Generally youhave many opportunities to get a house sitting job．

E．You must takea little care over what your description says about you．

F．This is aninternational house sitting service for all city and country areas．

G．Youmust have a good car, so you can travel to different parts of the country．

    Travelling around the world with children is difficult enough, while attempting it without using motorized transport is even more of challenge．Even so, Dario Schworer a 42-year-old climatologist and mountain guide, and his 33-year-old wife Sabine are on a journey to do just that．

    The Swiss couple want to travel across the world's oceans and climb the highest mountain on every continent to promote Earth-friendly ways of life．

    "We are collecting good examples of dealing with climate change and living in harmony with nature and we want to spread such ideas．" Schworer said．"We want to help people affected by global warming and to inspire children for the future．"

    Recently after having spent three months teaching children in the Everest region, the couple want to show it is possible to travel through the world's climate zones using just human-power and forces of nature．

    In the 47 countries they have visited they have collected 22 tons of trash, taught people in Ecuador how the sun's rays can be used to clean water and inspired a person in Chile to build a house on water with recycled plastic bottles as a foundation．They have also collected trash in the mountains of Nepal with school children．

    So far they have communicated with 45,000 children from South America, Australia and Asia, giving presentations about the importance of recycling and using alternative energy like solar and wind power．

    When they began their adventure in 2003 they had no children of their own．But since then two has become five: daughter Sabine is now five years old, Andri was born in Chile and baby Neo was born in Australia．

    Initially the couple thought they would complete their travels in four years, but now, they believe it could take seven more．

    "Since our belief is the need to respect nature, we travel only when conditions are good," Schworer said．

Four apps for students to learn English

    Quizlet

    Quizlet is a learning app—a computer program you use on your mobile device. It can help users build and test their knowledge of English words and terms. Quizlet has word sets for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.

    Socrative

    In Socrative, teachers can create timed learning games. In class, students compete individually or as part of a team against classmates. One game students love is called space Race. In this game, if a team answers a question correctly, their rocket moves forward. This team whose rocket gets to the end first wins. Also, teachers can use Socrative as an “exit ticket, ”a question they can ask students about what they learned in that day's class. Students write their answers on their mobile devices. Then, the teacher can show the answers on a shared video screen.

    QR Codes

    AQRCodeisakindofsignthatasmartphonecanreadwithitscamera. When your phone camera reads a QR code, it takes you to a website, image, video or anything you want to share. For example, one will take you to the VOA Learning English website.

    Evernote

    Evernote lets users store and share notes, images and recordings in one place. Teachers can also use Evernote to give homework.

    After Mom died, I began visiting Dad every morning before I went to work. He was frail and moved slowly, but he always had a glass of freshly squeezed orange juice on the kitchen table for me, along with an unsigned note reading, "Drink your juice." Such a gesture, I knew, was as far as Dad had ever been able to go in expressing his love. In fact, I remember, as a kid I had questioned Mom "Why doesn't Dad love me?" Mom frowned, "Who said he doesn't love you?" "Well, he never tells me," I complained. "He never tells me either," she said, smiling. "But look how hard he works to take care of us, to buy us food and clothes, and to pay for this house. That's how your father tells us he loves us."

    I nodded slowly. I understood in my head, but not in my heart. I still wanted my father to put his arms around me and tell me he loved me. Dad owned and operated a small scrap (片) metal business, and after school I often hung around while he worked. Dad fed scrap steel into a machine which looked like a giant pair of scissors with blades thicker than my father's body. If he didn't feed those terrifying blades just right, he risked serious injury. "Why don't you hire someone to do that for you?" Mom asked Dad one night as she bent over him and rubbed his aching shoulders . "Why don't you hire a cook?" Dad asked, giving her one of his rare smiles.

    Many years later, during my first daily visit, after drinking the juice my father had squeezed for me, I walked over, hugged him and said, "I love you, Dad." From then on I did this every morning. My father never told me how he felt about my hugs, and there was never any expression on his face when I gave them.

    Chicago is considering firm measures to prevent the Asian carp, a giant fish native to the Far East, from coming into North America's Great Lakes in large numbers. Such a move could cost up to$18bn, a heavy economic burden to the city.

    This species, more than a metre in length, was originally introduced to southern US states three decades ago to control weeds in sewage (污水) treatment plants. But they escaped into the Mississippi River and increased in number quickly, making their way north towards the Great Lakes and threatening the native fish species along the way.

    "Dozens of them will often leap out of the water as boats approach." Michael Beecham, a local environmental expert, described how frightening the scene was. "I've gone down the river and seen these fish jump up and hit me in the face. It is a big problem for our native species." he said.

    A meeting has been organized to find a technological solution to the carp problem, one of which involves blocking parts of Chicago's canal system. Listening at the meeting was John Goss, who was worried about the effect that having barriers in the canal system would have on industry. "It would certainly increase the cost of transportation," he told. "It is currently very cheap and efficient to bring materials and finished goods down the Chicago ship canal.''

    Another cheaper option is to eat the fish out of existence. Dirk Fucik is selling carp burger(鲤鱼汉堡包) at his fish shop not far from downtown Chicago. He thinks the carps are a great resource. "To catch it and throw it away is a waste," he says. "Eating them helps solve the problem and also provides jobs." But the idea has not yet caught on. So far, he is the only person in Chicago selling carp burgers.

The weather in Texas may have cooled since the recent extreme heat, but the temperature will be high at the State Board of Education meeting in Austin this month as officials debate how climate change is taught in Texas schools.

Pat Hardy, who agrees with the views of the energy department, is resisting proposed changes to science standards for pre-teen pupils. These would emphasize the significance of human activity in recent climate change and encourage discussion of reduction measures.

Most scientists and experts sharply argue against Hardy's views. "They casually view the career work of scholars and scientists as just another misguided opinion," says Dan Quinn, senior communications strategist at the Texas Freedom Network, a non-profit group that monitors public education. Such debates reflect fierce discussions across the US and around the world, as researchers, policymakers, teachers and students step up demands for a greater focus on teaching about the facts of climate change in schools.

A study, looking at how state public schools across the country address climate change in science classes, gave barely half of US states a grade B+ or higher. Among the 10 worst performers were some of the most populous states, including Texas, which was given the lowest grade (F) and has a huge influence because its textbooks are widely sold elsewhere.

Glenn Branch, the center's deputy director, cautions that setting state-level science standards is only one limited norm in a country that decentralizes (使分权)decisions to local school boards. Even if a state is considered a high performer in its science standards, "that does not mean it will be taught", he says.

Branch points out that, even if a growing number of official guidelines and textbooks reflect scientific consensus (共识) on climate change, unofficial educational materials that convey more biased(带有偏见的) perspectives are being distributed to teachers. They include materials sponsored by libertarian think-tanks(智库) and energy industry associations.
