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.

    Humans like to live and work in groups. Language is the “cement”(胶合剂){#blank#}1{#/blank#}holds these groups together. Language is part of culture. Culture, in this sense{#blank#}2{#/blank#}(mean)all those customs, skills, and attitudes that are part of the behavior of a {#blank#}3{#/blank#}(particularly) group. What you think {#blank#}4{#/blank#}what you want in life are all affected by the culture of the group in which you{#blank#}5{#/blank#} (raise). Groups of people live in different ways. They may have different skills, organizations, and art forms. Their family life may be completely different from yours.

    Human beings are inventive animals. They can decide to change their cultures in order to meet various{#blank#}6{#/blank#}(situation). Of all living things, human beings are the  {#blank#}7{#/blank#}(clever). They can choose {#blank#}8{#/blank#}(live)in many environments and in a wide variety of ways. Only human beings can choose where and how they want to live and then improve the physical environment to help{#blank#}9{#/blank#} (they)realize these choices. Acquiring the wisdom to make wise choices {#blank#}10{#/blank#}(be) the lasting challenge of being human.

Over the past years Starbucks coffee{#blank#}1{#/blank#}(become) a coffee chain store. The cafes don't sell coffee; they sell{#blank#}2{#/blank#}very atmosphere. They offer customers the perfect atmosphere{#blank#}3{#/blank#} which to take time out and relax. Every single store throughout the world is furnished in a romantic style and {#blank#}4{#/blank#}(special) meant to be cozy, private and quiet: earth-toned (褐色调) space, fancy wall paper, lovely paintings,{#blank#}5{#/blank#} (amaze) background and irresistible coffee smell……The most fantastic decoration style about Starbucks {#blank#}6{#/blank#}(design) with oversized chairs and tables outside the store. When{#blank#}7{#/blank#}comes to a sunny afternoon, I love to take a seat outside,{#blank#}8{#/blank#} (bath) in the afternoon sunshine, and listening to the lovely music{#blank#}9{#/blank#}tasting the most terrific Cappuccino. This is exactly what I love in here —-the Starbucks ! This is the café I love not merely because of the café itself, but also because of the {#blank#}10{#/blank#}(feel) it brings me.

    Saint Patrick's Day is a major holiday in Ireland, but the rest of the world has influenced its celebration as much as the Irish{#blank#}1{#/blank#} (they). Most Americans think of Saint Patrick's Day as a big party{#blank#}2{#/blank#}(center) around drinking alcohol. But its {#blank#}3{#/blank#} (origin) in Ireland were religious, says Mike Cronin, a professor of Irish history with Boston College of Massachusetts.

    Saint Patrick lived in Ireland more than 2,000 years ago. He is{#blank#}4{#/blank#} (wide) considered to have established Christianity in the country. The Church decided to honor him with a holy day. March 17, the date of his death{#blank#}5{#/blank#} (choose) in the 17lh century.

    St. Patrick is believed{#blank#}6{#/blank#}(serve) in Ireland as a Catholic Bishop (主教). The average Irish person honored March 17 quietly{#blank#}7{#/blank#}(attend) church services was the main activity. In fact, most businesses that served alcohol would close in honor {#blank#}8{#/blank#} the day. In the early 1900s, Ireland's government made St. Patrick's Day{#blank#}9{#/blank#} official holiday. By the 1960s, towns across Ireland started celebrating the holiday with parades and music.

    In Ireland today, St. Patrick's Day is a four-day public celebration {#blank#}10{#/blank#} includes parades, music, food, and games.

    Several days ago, a letter attracted a lot of attention on the Internet. It was written to NASA by 9-year-old Jack Davis {#blank#}1{#/blank#}(ask) to be considered for a job working with astronauts. He wrote to apply {#blank#}2{#/blank#} a planetary protection officer position at NASA. Despite his young age, he thought he would be fit for the job {#blank#}3{#/blank#} (perfect).

    With a pencil, he wrote: “I may be nine, but I think I would be {#blank#}4{#/blank#} good fit. My sister says I am an alien. Also, I.{#blank#}5{#/blank#} (see) all the space and alien movies in the past years.” Jack ended the letter stating the other {#blank#}6{#/blank#} (factor) that would make him perfect for the position, such as his great video game skills and his youth,{#blank#}7{#/blank#} would make it easy to learn to think like an alien. He then signed the letter, “Jack, Guardian of the Galaxy.”

    The position of planetary protection officer is well-paid every year. The job, however, is more about science and biology and {#blank#}8{#/blank#} (little) about fighting aliens. The officer must make sure that no new species or plants {#blank#}9{#/blank#} (bring) to other planets, and doesn't return from trips to space with anything that might harm Earth. The recent announcement of the position created in the 1960s has caused a lot of {#blank#}10{#/blank#} (excite) in the public, according to a NASA's statement.

    China has once again proved its {#blank#}1{#/blank#} (able)to change the world with the “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping.

    They're related to China's high-tech innovation(创新),{#blank#}2{#/blank#} has improved the quality of people's lives, according to a survey{#blank#}3{#/blank#}(make)by the Belt and Road Research Institute of Beijing Foreign Studies University.

    “My wallet is no longer in use. I can buy and eat whatever I want simply with a fingertip on my phone,” said{#blank#}4{#/blank#} university student, adding that “even pancake sellers are using mobile payment.”

    The bikes {#blank#}5{#/blank#}(them)are not new, but the operating model of bike-sharing {#blank#}6{#/blank#}(base)on satellite navigation system, mobile payment, big data and other high technologies.

    China has entered a new innovative era, thanks to the large amounts of capital China has invested in {#blank#}7{#/blank#}(encourage)innovation, said Bernhard Schwartlander, WHO Representative in China.

    {#blank#}8{#/blank#}is increasingly clear that China is innovating and no longer copying western ideas. This is {#blank#}9{#/blank#}(especial)true in mobile, where China is leading in many ways such as…social messaging app WeChat, she said. This is partly because China skipped over the PC era and went directly to mobile. China has the {#blank#}10{#/blank#}(large)mobile use in the world.
