Each year {#blank#}1{#/blank#}(thousand) of tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people traveling to the ends of the Earth can have {#blank#}2{#/blank#}negative effect on fragile ecosystems. Should tourists {#blank#}3{#/blank#}(allow) to visit polar regions?

    About 40,000 tourists visit Antarctica each year. More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions {#blank#}4{#/blank#}(increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other {#blank#}5{#/blank#}(environment) damage. Because the places where wildlife is accessible {#blank#}6{#/blank#}(be) few in number, tourist traffic can become concentrated in specific areas, {#blank#}7{#/blank#} (put)Arctic vegetation at risk.

    Others say that access {#blank#}8{#/blank#}these very special parts of the world should not be restricted to only researchers and scientists. Polar tourism allows people to develop deep  {#blank#}9{#/blank#}（person） connections with polar regions. “Those {#blank#}10{#/blank#}travel to the Arctic or Antarctica often become cheerleaders for supporting those places.” Jim Sano, vice president for travel and conservation at World Wildlife Fund, told TFK.

    In only fifty years, English{#blank#}1{#/blank#}(develop) into the language which is most{#blank#}2{#/blank#}(wide) spoken and used in the world. English is the working language of most international organizations, international trade and tourism. Businessmen and tourists often come to China without being able to speak{#blank#}3{#/blank#}. Chinese businessmen, taxi drivers and students talk with them using English. English is also the language of{#blank#}4{#/blank#}(globe) culture, such as popular music and the Internet. You can listen to English songs{#blank#}5{#/blank#}the radio{#blank#}6{#/blank#}use English to communicate{#blank#}7{#/blank#}people around the world through the Internet. With so many people{#blank#}8{#/blank#}(communicate) in English every day, it will become{#blank#}9{#/blank#}(important) to have{#blank#}10{#/blank#}good knowledge of English.

    China has always been famous for being a “State of Etiquettes (礼仪)”. According to {#blank#}1{#/blank#} (history) documents, as early as 2,600 years ago, this nation has already established a thorough set {#blank#}2{#/blank#} dining etiquettes. A famous 19th century Russian writer, Anton Chekhov, once invited a Chinese man {#blank#}3{#/blank#} (have) a drink in a bar. Chekhov said, “Before drinking from his cup, he held {#blank#}4{#/blank#} with his hands and presented to me and the bar owner and bar tenders, {#blank#}5{#/blank#} (say) “qing (please).” This is the custom of China. They are not like us to finish it in one drink, {#blank#}6{#/blank#} prefer to drink by taking a small amount at a time. With every sip (一小口), he {#blank#}7{#/blank#} (eat) some food. Afterwards he handed me some Chinese coins to show {#blank#}8{#/blank#} (grateful). This is a rather interestingly polite nationality. This was the most valuable opinion of a Chinese person {#blank#}9{#/blank#} was given by a foreigner two centuries ago. Chinese traditional dinner procedures used to be long and dealt seriously with. The {#blank#}10{#/blank#} (important) the occasion, the more complex the procedures were.

    There is a wonderful story about Jimmy Durante, {#blank#}1{#/blank#}is one of the great singers in the twentieth century. One day, when {#blank#}2{#/blank#}(ask)to be part of a show for some old World War II soldiers, Jimmy said he could afford only a few minutes and {#blank#}3{#/blank#}he would come if they wouldn't mind his singing one short song and immediately leaving for his next appointment. Of course, the show's director agreed happily.

    But when Jimmy got on stage, something {#blank#}4{#/blank#}(surprise) happened. He went through the short song and then stayed. The applause grew louder and louder and he kept staying. Pretty soon, he had been on stage{#blank#}5{#/blank#}fifteen, twenty, and then thirty minutes. One of his assistants behind the stage stopped him and said, “I thought you had to go after a few minutes. What happened?” Jimmy answered, “I did have to go, but I can show you the reason{#blank#}6{#/blank#} I stayed. You can see for yourself if you look at the front row.” In the front row {#blank#}7{#/blank#}(be) two men, both of {#blank#}8{#/blank#}had lost an arm in the war. {#blank#}9{#/blank#}had lost his right arm and the other had lost his left. Together, they were able to clap, and that was exactly{#blank#}10{#/blank#} they were doing, loudly and cheerfully.

    "Living within 300 metres of green space {#blank#}1{#/blank#} (associate) with greater happiness, sense of worth and life satisfaction," says a new study. {#blank#}2{#/blank#} (use) data from UK government's Annual Population Survey (APS) of 25518 people, the researchers show that people {#blank#}3{#/blank#} live within 300 metres of green space have significantly better mental well-being. "A lot of research focuses {#blank#}4{#/blank#} poor mental health, or single aspect of well-being like life satisfaction. What makes our work different is the way we consider multi-dimensional mental well-being in terms of happiness, life satisfaction and worth," said Victoria Houlden from the University of Warwick.

    The study, {#blank#}5{#/blank#} (publish) in the journal Applied Geography, found that there is a very strong relationship between the amount of green space around a person's home {#blank#}6{#/blank#}  their feelings of life satisfaction, happiness, and self-worth. Green space within 300 metres of home made the greatest {#blank#}7{#/blank#} (differ) to mental well-being. The study found that access to green space was {#blank#}8{#/blank#} (important) than lifestyle factors such as employment, income and general health. "By {#blank#}9{#/blank#} (combine) advanced statistical and mapping methods, we've shown that the effect is real. {#blank#}10{#/blank#} (basical) we've proven what everyone has always assumed was true," said Scott Weich, Professor at the University of Sheffield.
