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.”

    Polar bears are suffering in a much {#blank#}1{#/blank#} (warm) world.

    Polar bears live in environments too cold for most animals. During much of the year, they live and hunt on the frozen Arctic sea ice. Nature has {#blank#}2{#/blank#} （prepare）them for the cold conditions. But nothing has prepared the bears for the danger {#blank#}3{#/blank#} threatens the only home they know.

    The polar bears' world is melting. Studies show that the amount of the polar ice {#blank#}4{#/blank#}（have）decreased by 9.8% every 10 years since 1978. Now about 20,000 to 25,000 polar bears live in the Arctic. Polar bears rely {#blank#}5{#/blank#} the sea ice for their survival. “The sea ice is more {#blank#}6{#/blank#} just this platform that the bears walk over,” says Andrew Derocher, {#blank#}7{#/blank#} scientist who studies North American polar bear populations. “{#blank#}8{#/blank#} it, they can't exist.”

    Some melting and refreezing of the polar ice is natural. But in a warmer world, these cycles speed up, and bears have less time {#blank#}9{#/blank#} (hunt). Normally, they have three months in the spring when they gain more weight. The extra fat is used later, when the bears are not {#blank#}10{#/blank#}(active) hunting.

    Does the age gap matter in a relationship?

    The love story of French President Emmanuel Macron and Brigitte Trogneux, 24 years his senior, has aroused heated discussion on age differences {#blank#}1{#/blank#} relationships. Does age matter or should love prevail(战胜) over all?

    I find {#blank#}2{#/blank#} a very heartwarming love story. Not just this couple,{#blank#}3{#/blank#}any couple - what does age difference matter after all? If they love each other,{#blank#}4{#/blank#} ( devote) to the relationship and work on making it strong, that is what{#blank#}5{#/blank#} (count).

    It is nearly impossible for Chinese women to accept Macron's relationship. It is  {#blank#}6{#/blank#} (common) for older men to marry younger women, but for an older woman to marry a younger man is often seen as {#blank#}7{#/blank#} (appropriate). If you get along well, go for it, it's your life and life is way too short{#blank#}8{#/blank#} (let) a potential soul mate get away because of what you think others would say. I think it really doesn't matter. It is involved in the {#blank#}9{#/blank#} (devote) of the people and how well they enjoy each other's company is important along with supporting each other {#blank#}10{#/blank#}(emotion), financially etc....

    Overweight children and teenagers aged between 5 and 18 in the China mainland {#blank#}1{#/blank#} (reach) 8.5 million in 2025, a number {#blank#}2{#/blank#} surpasses (超过) the population of Spain, a study said.

    According to the study, among the obese Chinese youth, millions of them {#blank#}3{#/blank#} (report) to suffer from all kinds of diseases. It also stated that in all there would be 268 million overweight school aged children worldwide by 2025, {#blank#}4{#/blank#}(include) 91 million obese children, if no effective {#blank#}5{#/blank#} (measure) could be taken to stop the existing trends. Inactivity and the consumption of junk food and soda drink contributed {#blank#}6{#/blank#} the growing number of overweight {#blank#}7{#/blank#} (young) in the world. {#blank#}8{#/blank#} (respond) to the increase of obese children in China, the State Council released a guideline this year. The guideline aimed to prevent more children from becoming obese and it urged that the local government in China {#blank#}9{#/blank#} (strength) the training of medical staff around children's health and promote knowledge of {#blank#}10{#/blank#} (balance) eating and drinking habits among their parents.

    I had hardly sat down on the train and opened a bar of chocolate {#blank#}1{#/blank#} a really old man with huge bags sat down across from me. I said hello {#blank#}2{#/blank#} him, smiling sweetly and then I suddenly thought, "Why not offer him a piece of chocolate？" So I did. He was quite {#blank#}3{#/blank#} (surprise), but accepted and thanked me. He said that people didn't usually do things like this for {#blank#}4{#/blank#} (strange) and at least that was what I understood, because he was speaking a really {#blank#}5{#/blank#} (usual) dialect.

    Then he opened one of his bags and gave me {#blank#}6{#/blank#} handful of freshly picked cherries, {#blank#}7{#/blank#} (explain) that he had just taken them from his orchard. The cherries were really lovely, better than those in the shops, and I enjoyed them very much. It had been just an impulse (冲动) to offer him a piece of chocolate, but if I {#blank#}8{#/blank#} (not do) so, I would never have tasted those lovely cherries, {#blank#}9{#/blank#} I didn't even know he had at the time. Life is about giving and taking, and it's {#blank#}10{#/blank#} (general) true that if you give, you will receive.
