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.

    Sun Yat-sen,{#blank#}1{#/blank#} was the leader of the 1911 Revolution, first suggested the idea of a dam across the Yangtze River in 1919. Three quarters of China's energy {#blank#}2{#/blank#} (produce) by burning coal. In 1993, China used 1.2 billion tons of coal for heating and generating{#blank#}3{#/blank#}(electric).{#blank#}4{#/blank#} (fortunate), burning coal causes serious air pollution and increases global warming. The dam will generate electricity equal{#blank#}5{#/blank#} about 40 million tons of coal without causing so much air pollution.

    Many people may think the Forbidden city, or the Palace Museum as it's also called, is {#blank#}1{#/blank#} great, old-fashioned museum. {#blank#}2{#/blank#}, in recent years, the museum has been working hard {#blank#}3{#/blank#} (promote) Chinese cultural heritage among the young people.

    The museum s online store now offers special cultural and creative {#blank#}4{#/blank#} (product). For example, in 2014, it{#blank#}5{#/blank#} (begin) to sell earphones that look like the necklaces worn by ancient officials , which even brought in {#blank#}6{#/blank#} (rough) 1 billion yuan a year.

    Last year, a documentary {#blank#}7{#/blank#} (name) Masters in the Forbidden City became popular online. It is about the people {#blank#}8{#/blank#} job is to repair the relics in the museum. Many of these workers are very young and some are even {#blank#}9{#/blank#} their 20s.

    Some other museums across the country, such as the National Museum of China, {#blank#}10{#/blank#}(inspire) by the Palace Museum's efforts and are working on similar projects of their own.

    Few people I know seem to have much desire or time to cook. Making Chinese {#blank#}1{#/blank#}(dish) is seen as especially troublesome. Many westerners {#blank#}2{#/blank#} come to China cook much less than in their own countries once they realize how cheap {#blank#}3{#/blank#} can be to eat out. I still remember {#blank#}4{#/blank#} (visit) a friend who'd lived here for five years and I {#blank#}5{#/blank#}(shock) when I learned she hadn't cooked once in all that time.

    While regularly eating out seems to {#blank#}6{#/blank#}(become) common for many young people in recent years, it's not without a cost. The obvious one is money; eating out once or twice a week may be {#blank#}7{#/blank#}(afford) but doing this most days adds up. There could be an even {#blank#}8{#/blank#} (high) cost on your health. Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in{#blank#}9{#/blank#}(weigh) problems.

    If you are not going to suffer this problem, then I suggest that the next time you go to your mum's home {#blank#}10{#/blank#} dinner, get a few cooking tips from her. Cooking food can be fun. You might also begin to notice the effects not only on your health but in your pocket.

    A CCTV joumalist succeeded in arousing a heated discussion among citizens by asking people {#blank#}1{#/blank#} they were happy. The responses to the question were{#blank#}2{#/blank#}(variety), even some quite hinny ones included. Although people played jokes on the answers, it did not take long{#blank#}3{#/blank#} they began to figure out the true meanings of happiness.

    It is certain that people's views on happiness{#blank#}4{#/blank#}(affect) greatly by their own life experience. Unfortunately, too many people refer to being rich as happiness and there is no sign of{#blank#}5{#/blank#} decrease in the number of those who are voluntarily at the mercy of wealth. Some people whose intention is {#blank#}6{#/blank#}(make) big money appreciate being given any chance to multiply their income, believing that is{#blank#}7{#/blank#}their happiness lies. Some arc eager to inherit (继承) their parents' property, especially those who {#blank#}8{#/blank#} (be) known as silver-spoon kids (富二代).Even worse, some would rather break the law to satisfy their financial desire or seek their fortune {#blank#}9{#/blank#} (legal).

    In my opinion, happiness is not about pursuing wealth merely but about admiring the beautiful things in life. Therefore, live your life {#blank#}10{#/blank#} the fullest and be happy.
