Swedish businessman Nile Bergqvist is delighted with his new hotel, the world's first igloo(冰屋) hotel.

    {#blank#}1{#/blank#} (build) in a small town, it has been attracting lots of visitors but soon the fun will be over. In two weeks' time，Bergqvst's ice creation {#blank#}2{#/blank#} (be) nothing more than a pool of water. “We don't see it as a big problem,” he says. “We just look forward to {#blank#}3{#/blank#} (replace) it.”

    Bergqvist built his first igloo in 1991 for an art exhibition. It was {#blank#}4{#/blank#} successful that he designed the present one, {#blank#}5{#/blank#} measures roughly 200 square meters. Six workmen spent more than eight weeks —piling 1,000 tons of snow onto a wooden base；when the snow froze, the base {#blank#}6{#/blank#} (remove).

After their stay, all visitors receive a survival certificate recording their success. {#blank#}7{#/blank#} no windows, nowhere to hang clothes and temperatures below 0℃, it may seem more like a survival test {#blank#}8{#/blank#} a relaxing hotel break. “It's great fun,” Bergqvist explains, “as {#blank#}9{#/blank#} as a good start in survival training.''

    The {#blank#}10{#/blank#} (popular)of the igloo is beyond doubt：it is now attracting tourists from all over the world. At least 800 people have stayed at the igloo this season even though there are only 10 rooms.

    Many Chinese believe{#blank#}1{#/blank#}(eat) pig brains will increase their intelligence and some Americans regularly eat{#blank#}2{#/blank#} (cook) eggs to keep their minds sharp.  {#blank#}3{#/blank#} doctors don't recommend eating{#blank#}4{#/blank#} raw eggs or animal brains. Then, what food is good for your brain? Scientists have found a relationship  {#blank#}5{#/blank#} diet and a healthy brain. Generally speaking, fish is {#blank#}6{#/blank#}brain food. Besides fish, you should introduce lots of dark green leafy vegetables and colorful fruits into your diet,{#blank#}7{#/blank#} most people lack the special vitamins{#blank#}8{#/blank#} these brain food provide. If you eat brain foods{#blank#}9{#/blank#}(regular), they can increase brain power — help you pay attention, keep you motivated, improve your memory and {#blank#}10{#/blank#}(less) stress from studies. Then you can do much better in your test.

    The Great Wall of China{#blank#}1{#/blank#}(list) in the World Cultural Heritage(世界文化遗产) by UNESCO in 1987. Just{#blank#}2{#/blank#} a huge dragon, it winds up and down across deserts grasslands and mountains, covering{#blank#}3{#/blank#} (approximate)6, 700 kilometers from the east to the west of China.

    In ancient China, many people built walls around their states to protect their land. It was Emperor Qing Shihuang who had the walls{#blank#}4{#/blank#}(join) up. The project cost much money and hundreds of thousands of people worked on{#blank#}5{#/blank#} wall. On top of it, it is wide enough for five horses or ten men{#blank#}6{#/blank#} (walk) side by side. Along the wall are watchtowers, {#blank#}7{#/blank#}soldiers used to keep watch. With a history of more than 2000 years, some of the sections of the Great Wall are now in ruins or even disappeared. However, it is still one of the most{#blank#}8{#/blank#} (attract) spots around the world because of its wonderful buildings and historical{#blank#}9{#/blank#}(important). Many of the tourists have come to know the famous Chinese saying— "He who does not reach the Great Wall {#blank#}10{#/blank#} (be) not a true man.”
