The story happened in ancient times. A king was so clever that he thought of a good way to test{#blank#}1{#/blank#}his men were reliable.

    One day, he had a huge rock{#blank#}2{#/blank#}(place) on a roadway at night. Then he hid {#blank#}3{#/blank#} (him) nearby and watched carefully to see if anyone would remove the big rock. Some{#blank#}4{#/blank#}(wealth) businessmen and high officials came by, but they simply walked around it. Many of them even loudly blamed the king for not keeping the roads clear, but none of them would bother{#blank#}5{#/blank#}(get) the big stone out of the way.

    Then a villager came along carrying a load of vegetables. On {#blank#}6{#/blank#}(approach) the big rock, he stopped and laid down his burden, trying hard to move the stone to the side of the road. After much pushing, he{#blank#}7{#/blank#}(final) succeeded. As the villager picked up his load of vegetables, he noticed a purse lying in the road where the rock{#blank#}8{#/blank#}(be). The purse contained many gold coins and a note from the king, saying that the gold was for the person{#blank#}9{#/blank#} removed the huge rock from the road.

    The villager learned a valuable lesson that many others would never understand: Every obstacle presents{#blank#}10{#/blank#} opportunity to improve one's condition.

    Whether enveloped by the thick smog from factories or unseen poisons from vehicle waste gases, many cities around the world are losing the battle against air pollution．

    Somewhere, many people died from breathing in the smoke and harmful gases {#blank#}1{#/blank#} (pour) into the air．In China and India, the damage of this poisonous air is particularly alarming, {#blank#}2{#/blank#}(cause) three million deaths in those two countries．As a result, some out-of-breath citizens are turning to bottled air．

    Many companies are compressing fresh countryside air into bottles and {#blank#}3{#/blank#} (sell) it online．It sounds like a joke but the idea is to raise {#blank#}4{#/blank#}(aware) and it provided people {#blank#}5{#/blank#}fresh air at a price．One such company is Vitality, {#blank#}6{#/blank#} collects air from the Canadian Rockies and compresses it into container．Vitality started the business to sell the canned air as joke gifts at first．{#blank#}7{#/blank#} the products took off in a {#blank#}8{#/blank#} ( surprise) way then．So, the manager came up with the business idea {#blank#}9{#/blank#} they can sell fresh air over the world．The manager of the company  has  made {#blank#}10{#/blank#}clear that China, India and South Korea have become its main markets．

    What might life be like if you looked very different from others? Most of us are lucky to be born with "normal" faces.{#blank#}1{#/blank#}, the movie Wonder shows us that there is no such thing as being normal and that beauty is more than skin-deep.

    {#blank#}2{#/blank#} (base) on a bestselling novel, the movie is about a boy named Auggie. He has a facial deformity (畸形) and has spent most of his life being home schooled. But as he enters middle school, his parents decide to send him to a private school. There, Auggie must deal with judgmental classmates and learn to accept{#blank#}3{#/blank#} (he) as he is.

    In the US, most kids{#blank#}4{#/blank#} (teach) that it is OK to be different. Most people in the US celebrate being unique. But some kids have difficulty{#blank#}5{#/blank#} (accept) uniqueness. It's easy to pick on someone who's different, {#blank#}6{#/blank#}(especial) if you have your own problems to deal with. This is another{#blank#}7{#/blank#} (center) theme from the movie—even the kids {#blank#}8{#/blank#}pick on Auggie have their own personal struggles.

    As Auggie's classmates get to know him better, they come to find that he's a nice kid {#blank#}9{#/blank#}a great sense of humor. They start to change their attitude toward him. In real life, it may take longer to see such changes happen. But if we give people {#blank#}10{#/blank#}chance, their hearts and minds may change in the end.

    Moving silently through Alibaba Group Holding Ltd's "FlyZoo" hotel, black disc-shaped robots about a metre in height deliver food and drop off fresh towels.

    The robots are part of a set of high-tech tools that Alibaba {#blank#}1{#/blank#} (say) extremely cuts the hotel's cost of human labour and removes the need for guests to interact {#blank#}2{#/blank#} other people.

    Inside the hotel, softly-lit white panelled walls bring to mind {#blank#}3{#/blank#} insides of Hollywood spaceships. Guests check in at reception desks that scan {#blank#}4{#/blank#} (they) faces, as well as passports or other ID. {#blank#}5{#/blank#} (visit) with a Chinese national ID can scan their faces using their smartphones to check in ahead of time.

    At the hotel's restaurant, taller capsule-shaped robots deliver food that guests {#blank#}6{#/blank#} (order) via the FlyZoo app while at a separate bar, a large robotic arm can mix more than 20 different types of cocktails. Facial recognition cameras add charges to the room rate {#blank#}7{#/blank#} (automatic).

    The hotel does employ humans, {#blank#}8{#/blank#} Alibaba refused to tell how many. This includes chefs and cleaners as well as reception staff, {#blank#}9{#/blank#} will assist with conventional check-in procedures for guests unwilling to have their faces {#blank#}10{#/blank#} (scan) and want to use electronic key cards.

    As everyone know s, it is Jingdezhen in Jiangxi province {#blank#}1{#/blank#} the local porcelain (瓷器) is highly desirable that is the center of world porcelain. Last year, my school {#blank#}2{#/blank#} (hold) a two-day research activity, guided by the slogan, "Exploring ceramic(陶瓷的)culture, traveling through ancient and modern times". The aim was to build students' {#blank#}3{#/blank#} (aware) of traditional culture.

    On our way to Jingdezhen, our guide introduced us to the basics of porcelain production. Our first stop was the Museum of Chinese Ceramics, which has {#blank#}4{#/blank#} unique and exquisite collection of porcelain made from materials such as clay(陶土)and stone.

    The guide told us of the great achievements in ceramics from ancient times until today. I listened carefully to everything. {#blank#}5{#/blank#} (date) back to Neolithic(新石器时代)period, clay was used {#blank#}6{#/blank#} (make) pottery(陶器), which people used to carry water and food. Today, we still use porcelain but our pottery is far more beautiful than the products of those times.

    On the second day, the team leader took us to a small DI Y porcelain factory. Under the {#blank#}7{#/blank#} (guide) of the teacher, we {#blank#}8{#/blank#} (give) some clay and the chance to design a piece of pottery. Although our efforts were not as beautiful as the articles in the museum, they w ere our own work. The two-day activity was very {#blank#}9{#/blank#} (enjoy) and meaningful. I learned a lot about porcelain and made an item {#blank#}10{#/blank#} my own. It meant a lot to me.

The college entrance examination is just around the corner. {#blank#}1{#/blank#} (assign) and tests will keep many of you up late at night, and you may plan to make up for your{#blank#}2{#/blank#} (lose) sleep during the weekends. But is it useful?

A study shows that the habit of sleeping in{#blank#}3{#/blank#} weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}4{#/blank#} (bad), it may damage your health.

In the study, {#blank#}5{#/blank#} was conducted over 10 days, 36 healthy young men and women with different sleep requirements {#blank#}6{#/blank#} (divide) into three groups. The researchers found that people who lacked sleep ate more snacks and gained {#blank#}7{#/blank#} (weigh) quickly. That could be partially due to the shifting of the{#blank#}8{#/blank#} (biology) clock and changes to certain body hormones especially hunger hormones.

And {#blank#}9{#/blank#} they tried to sleep for as long as they wanted to on weekend, it was still insufficient(不够的) to meet standard sleep time because they found it difficult to fall asleep. Moreover, they were more likely{#blank#}10{#/blank#}(show) increased sensitivity (敏感性) to insulin(胰岛素) in both their muscles and their livers.
