Colorful lanterns are lighting up China's night sky, as activities begin across the country to celebrate Lantern Festival today.

    {#blank#}1{#/blank#} (date) back to the Western Han Dynasty (206 BC-AD 25), the Lantern Festival is held on the 15th day of the first lunar month {#blank#}2{#/blank#}(mark) the first full moon of the lunar new year.

    You Guoqing, {#blank#}3{#/blank#} folk custom expert in Tianjin, said the Lantern Festival was about going out for a colorful celebration rather than a family get-together. {#blank#}4{#/blank#}watching lanterns, {#blank#}5{#/blank#} is also a day to appreciate the full moon, solve lantern riddles, watch art {#blank#}6{#/blank#}(performance) and eat tang yuan.

    The festival was once also a time for romantic encounters. In feudal times, young women were not allowed to go out {#blank#}7{#/blank#}(free), but Lantern Festival was an exception, {#blank#}8{#/blank#} young men and women could meet up.

    Some aspects of the festival, such as its romantic atmosphere, {#blank#}9{#/blank#} (fade), but people {#blank#}10{#/blank#} see the Lantern Festival as a day to rejoice and a chance to wish for happiness.

    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.

    When foreigners negotiate, or register in certain areas of China, they may be {#blank#}1{#/blank#}(surprise) at Chinese's special fondness and preference for seals. To Chinese, seals are an art of deep cultural roots, {#blank#}2{#/blank#} combines the essence of both calligraphy(书法) and sculpture and inspires generations to study, to appreciate and to collect.

    It is believed that seals came out as early {#blank#}3{#/blank#} 8,000 years ago after our ancestors could make pottery wares(陶瓷)and had private property. They were assumed to make marks on {#blank#}4{#/blank#}(they) own possessions to prevent them from being stolen. When the first dynasty {#blank#}5{#/blank#}(found),the king began to use seals to empower(授权)and to show lordly credits. Only the king's special seal was then called "Xi", {#blank#}6{#/blank#}(represent) the highest authority. The first emperor of China, Qin Shi Huang, had his "Xi"{#blank#}7{#/blank#}(make) out of the invaluable and beautiful jade "Heshi Bi".

    Then the local governments also needed seals for {#blank#}8{#/blank#} same function. Meanwhile, private seals were carved in a variety of lucky {#blank#}9{#/blank#}(character)and vivid animal patterns.{#blank#}10{#/blank#}(gradual). the sphragistics (印章学) came into being.

    The Hong Kong-Zhuhai-Macao Bridge, the world's{#blank#}1{#/blank#}(long) cross-sea bridge, enters the history of human engineering and connection as a point of pride upon {#blank#}2{#/blank#}(it) opening to traffic at 9 am on Oct.24, 2018.

    One day after the opening was announced at a ceremony{#blank#}3{#/blank#}(hold) in Zhuhai, the bridge's ports in three different administrative regions started serving travelers around-the-clock , opening 24 hours a day, seven days a week.{#blank#}4{#/blank#} (ensure) faster boundary crossings for passengers, the Macao and Zhuhai ports jointly use a one-off immigration clearance model,{#blank#}5{#/blank#}allows travelers to queue up only once to finish both exit and entry procedures of the two cities in about 30{#blank#}6{#/blank#}(second).

    Apart{#blank#}7{#/blank#}private cars, taxis and goods vehicles, two types of public transportation -shuttle bus(班车)and cross-boundary coach --can also run on the HZMB.{#blank#}8{#/blank#}frequency of shuttle buses is about 5-10minutes during peak hours. Booking tickets for the shuttle bus online in advance{#blank#}9{#/blank#}（be）available since 9 am on Tuesday. With the bridge now in service, the traveling time between Zhuhai and Hong Kong International Airport will{#blank#}10{#/blank#}(shorten) from four hours to 45 minutes, and the time between Zhuhai and Hong Kong's Container Terminals will be cut from 3. 5 hours to 75 minutes.
