One day a rich man took his son on a trip to the country so he could have his son see how poor country people were.

    They stayed one day and one night in the farm-house of {#blank#}1{#/blank#} very poor farm. {#blank#}2{#/blank#} the way back home at the end of the trip the father asked the son, “{#blank#}3{#/blank#} did you think of the trip?”

    The son  {#blank#}4{#/blank#} (reply), “Very nice, Dad.”

    The father then asked, “Did you notice how poor they were?”

    The son said, “Yes, I guess so.”

    The father then added, “What did you learn?”

    To {#blank#}5{#/blank#} question, the son thought for a moment and answered {#blank#}6{#/blank#} (slow), “I learned that we have one dog and they have four. We have a fountain in the garden and they have a small river{#blank#}7{#/blank#} has no end. We have brightly colored {#blank#}8{#/blank#} (lantern) in our garden, while they have the stars. Our garden {#blank#}9{#/blank#} (go) to the edge of our yard, but for their back yard they have the whole horizon.”

    At the son's reply, the rich father was speechless (无语的). His son then said, “Thanks, Dad, for{#blank#}10{#/blank#} (show) me how poor we really are.”

    In recent years many TV shows have become extremely popular among Chinese audience. Those programs, ranging from talent or dating shows to reality shows {#blank#}1{#/blank#}(receive) both commercial success and public attention.

    Their popularity is {#blank#}2{#/blank#}(main) based on simple facts. First, they care {#blank#}3{#/blank#} social concerns. Second, without exception, they explore {#blank#}4{#/blank#} perfect balance between the international forms and Chinese expressions.

    Despite apparent highlights, much room {#blank#}5{#/blank#}(leave) for improvement. Above all, commercial interests often outweigh educational purposes, causing many {#blank#}6{#/blank#}(complaint) about the {#blank#}7{#/blank#}(bearable) advertisements. In addition, some sharp remarks, {#blank#}8{#/blank#} they are eye-catching, may have misleading effects on the youth.

    In my opinion, such shows should shoulder more responsibility instead of merely {#blank#}9{#/blank#}(entertain) the public. {#blank#}10{#/blank#} is expected, these programs should be positive in their forms as well as functions. Meanwhile, the media should also safeguard the values of our society.

    The Chinese language is one of the{#blank#}1{#/blank#}（old）written languages in the world. It {#blank#}2{#/blank#}（speak）by the Han majority and many other ethnic groups in China. Nearly 1.3 billion people speak some form of Chinese as their first language.

    The{#blank#}3{#/blank#}（vary）of Chinese are usually described by native speakers as dialects of a single Chinese language，but linguists（语言学家）note that they are as diverse as a language family. There are between 7 and 13 main regional groups of Chinese, of{#blank#}4{#/blank#}the most spoken by far is Mandarin（普通话），{#blank#}5{#/blank#}（follow）by Wu, Min, Yue, etc. Standard Chinese is a standardized form of spoken Chinese based on the Beijing dialect of Mandarin. It is{#blank#}6{#/blank#}official language of China, and also one of the six official languages of the United Nations.

    {#blank#}7{#/blank#}many Chinese dialects exist，the written language is still a very common form of communication. If we go to{#blank#}8{#/blank#}（differ）provinces, we may not be able {#blank#}9{#/blank#}（communicate）with the local people orally. However, we can understand each other in writing. The written language can be further divided{#blank#}10{#/blank#}different forms, like simplified Chinese and traditional Chinese. There is also a form called "pinyin", which is the Chinese language with a Roman spelling.

    For some US college students, a break from school is a time to volunteer {#blank#}1{#/blank#} (help) communities in need. They take part in activities {#blank#}2{#/blank#} (organize) by school to do voluntary work.

    This spring break, I had the opportunity to go on one of these trips, and it was the {#blank#}3{#/blank#} (good) week of my entire life. I went with twelve other students and two adults down to Rocky Mount, North Carolina in the US. We worked on three houses, {#blank#}4{#/blank#} (build) roofs, painting, and decorating.

    It was very rewarding to see how much we {#blank#}5{#/blank#} (appreciate) by the people living in that town. Every time we went out somewhere for dinner, people came up to us to express {#blank#}6{#/blank#} (they) appreciation. This made us foul really good and {#blank#}7{#/blank#} (encourage) us to get more done each day.

    The trip wasn't all about work, however. We had {#blank#}8{#/blank#} amazing group of people who enjoyed one another's company, Wu created our own fun, {#blank#}9{#/blank#} helped us get to know each other well. At the end of the trip, I came home {#blank#}10{#/blank#} not only a great sense of success but also fourteen really good new friends.

    The heat wave that broke high temperature records in five European countries a week ago is now over Greenland, {#blank#}1{#/blank#} (cause) the surface of the islands vast ice sheet to melt at near-record levels and a huge {#blank#}2{#/blank#} (lose) of ice in the Arctic. On Wednesday alone, more than 10 billion tons of ice was lost to the oceans by surface melt, which is equal {#blank#}3{#/blank#} about 4,000,000 Olympic-sized swimming pools, said Ruth Mottram, a climate scientist with the Danish Meteorological Institute.

    Melting {#blank#}4{#/blank#} (increase) in recent decades because of climate change and has been decreasing accumulation from snow. Previously, during the 1970s and the 1980s, Greenland lost {#blank#}5{#/blank#} average of 50 billion tons of ice each year. From 2010 to 2018, that figure shot up to 290 billion tons {#blank#}6{#/blank#} (annual). This summer, the extent of the melt could surpass (超过) the record set in 2012, {#blank#}7{#/blank#} about 97% of the ice sheets surface began to melt. NASA-JPL Caltech reported at the time.

Greenland, the worlds largest island, {#blank#}8{#/blank#} (lie) between the Atlantic and Arctic oceans, with 82 per cent of its surface {#blank#}9{#/blank#} (cover) in ice. A June 2019 study by scientists in the U. S. and Denmark said melting ice in Greenland alone will add between 5 and 33 centimeters to the rising {#blank#}10{#/blank#} (globe) sea levels by the year 2100. If all the ice in Greenland melted, which would take centuries, the world's oceans would rise by 7.2 meters.

    China's research icebreaker Xuelong, {#blank#}1{#/blank#}126 crew members aboard on the 35th Antarctic research mission, on Thursday local time left the Zhongshan Station on {#blank#}2{#/blank#} (it) way back to China.

    Snow Eagle 601, China's first fixed-wing aircraft for polar flight, on Thursday night also departed from the Antarctic after {#blank#}3{#/blank#}(complete)all assignments.

    Xuelong, {#blank#}4{#/blank#} arrived near Zhongshan on Feb 9, supplied the station with fuel oil, and then picked up summer expedition team members at the Kunlun, Taishan and Zhongshan stations, as well as {#blank#}5{#/blank#}(member)of the fixed-wing aircraft project.

    Sixteen members of the Kunlun team {#blank#}6{#/blank#}(previous) completed all scientific expeditions at Dome Argus (Dome A), the South Pole's highest icecap. They, together with 21 members of the Taishan team, {#blank#}7{#/blank#}(return) to Zhongshan on Feb 8.

    The Zhongshan team completed tasks including installation of and tests for LiDAR, drilling of ice bed rock, atmospheric sounding {#blank#}8{#/blank#}(observe), surveys of birds and aerial exploration carried out by the fixed-wing aircraft.

    As the summer expedition team at Zhongshan left, 19 members would stay for winter expeditions.

    Also {#blank#}9{#/blank#}(know)as the Snow Dragon, the icebreaker carrying a research team set sail from Shanghai on Nov 2 last year, beginning {#blank#}10{#/blank#}country's 35th Antarctic expedition. It is expected to arrive in Shanghai in mid-March.
