The Amber Room {#blank#}1{#/blank#}to the great wonders of the world. It was originally {#blank#}2{#/blank#}(design) for the palace of Frederick Ⅰ. {#blank#}3{#/blank#}took the country's best artists about ten years to finish it. Everyone thought {#blank#}4{#/blank#}(high) of its style and design. Several tons of amber as well as gold and jewels were used to make it, so no wonder it is worth a lot of money. But later, the next King of Prussia decided to give it as a gift to Peter the Great, {#blank#}5{#/blank#} gave Prussia a troop of his best soldiers in {#blank#}6{#/blank#}. Unfortunately, during the Second World War, the Nazi Germany was at war with Russia. In 1941, Germany invaded (入侵)Russia, and the Russians had no time to {#blank#}7{#/blank#}anything from the Amber Room except some furniture and small art objects. When the Nazis saw the Amber Room, there was no {#blank#}8{#/blank#}that they liked it so much that they took it apart and in less than two days 100,000 pieces were put inside twenty-seven wooden boxes. The boxes were then put on a train for Konigsberg. Since then, the whole world has been in {#blank#}9{#/blank#} of the Amber Room. No one knows what {#blank#}10{#/blank#} (happen) to it and whether it still exists now. Maybe it will remain a mystery forever.

    Each year, thousands of people come to Shaanxi, China, to visit the Terracotta Army, which shows the life of Qin Shi Huang,{#blank#}1{#/blank#}country's first emperor.

    As one of the most famous tourist sights in the world, the Terracotta Army is a form of funerary (葬礼的) art{#blank#}2{#/blank#}(bury) with the First Emperor in 210 to 209 BC. It was designed{#blank#}3{#/blank#}(protect) the emperor in his afterlife.

Since their {#blank#}4{#/blank#}(discover), experts have questioned whether the life-size models of soldiers{#blank#}5{#/blank#}(base) on real warriors (勇士) or whether they came off a production line.

    In October a BBC documentary ( 纪录片) the Greatest Tomb on Earth: Secrets of Ancient China, suggested the inspiration for the Terracotta Warriors may have come{#blank#}6{#/blank#}Ancient Greece, about{#blank#}7{#/blank#}Archaeologist Li Xiuzhen said, "We now have evidence that close contact did exist between the First Emperor's China and the West."

    On the 41st International Museum Day, it was{#blank#}8{#/blank#}(official) announced that new technology has just made{#blank#}9{#/blank#}possible for visitors to be guided. Thanks to an interactive(交互式) 360-degree video, visitors can choose either to view the{#blank#}10{#/blank#}(figure) close-up or from a distance.

    A patent is an official document{#blank#}1{#/blank#}(give)to an inventor by a government. This document {#blank#}2{#/blank#}(general) gives inventors the right to stop anyone else from copying, using or selling the invention without their permission.

    Inventions are the result of hard work. It may only take a moment of inspiration to think of a good idea but it takes a lot of research and experimentation to turn it into a(n){#blank#}3{#/blank#} (use)and working invention. So, inventors deserve a reward for the amount of time they spend {#blank#}4{#/blank#}(develop)their ideas. They also need the {#blank#}5{#/blank#}(secure) of knowing that if they share the invention with {#blank#}6{#/blank#}rest of the world, nobody will steal it, use it or copy it without their permission.

    Patents also benefit the society {#blank#}7{#/blank#}return for patent protection. Inventors agree{#blank#}8{#/blank#}(show)all the technical information about their invention. This information is available to everyone and has enough details {#blank#}9{#/blank#}can be used by people with basic knowledge to produce the invention. In this way, patents help to spread new knowledge, which can in turn help people find {#blank#}10{#/blank#}(solve)to different problems or to make further advances in science and technology.

    Michael is {#blank#}1{#/blank#} American high school student. Like many schoolmates, Michael used {#blank#}2{#/blank#} (eat) breakfast while it was still dark. But that changed when his high school followed a new time schedule two years ago.

    The problem of school start time has become one of the most important issues {#blank#}3{#/blank#} are discussed in public. A growing number of sleep-related studies have pointed to high school students' need {#blank#}4{#/blank#} more sleep. More than half of the {#blank#}5{#/blank#} (child) between ages 15 and 17, as is shown by researches, sleep for 7 or {#blank#}6{#/blank#} (few) hours per night.

    Children like to stay up at night, usually going to bed late and waking up late in the morning. These habits may {#blank#}7{#/blank#} (cause) by the biology (生理), according to researchers. They think changing the sleep schedule of children {#blank#}8{#/blank#} (be) unable to work, "Only going to bed earlier will not {#blank#}9{#/blank#} (certain) make someone less tired in the early morning hours, "said a researcher. He also added, "Kids' lack (缺乏) of enough sleep is a growing public health problem in our nation. We need to work out ways to deal with {#blank#}10{#/blank#}. Putting off school start time may be helpful."

    When I left for the United States to study, I had butterflies in my stomach. I was nervous because I was going to {#blank#}1{#/blank#} new place with new people and new customs. I couldn't even understand {#blank#}2{#/blank#} (they) language. Everything was different {#blank#}3{#/blank#} my own country. There was nobody that I could talk to. I just had my husband, {#blank#}4{#/blank#} was a new person for me, too.

    It was a sad moment when I had to say goodbye to my family and friends. I didn't want {#blank#}5{#/blank#} (leave) my hometown because I grew up there and had wonderful {#blank#}6{#/blank#} (memory) of the place. So, {#blank#}7{#/blank#}(think) about all these changes made me nervous and I was {#blank#}8{#/blank#} (worry) about my new life. But studying abroad was a {#blank#}9{#/blank#}(decide) that I made myself. I had to continue and accept the challenge. I looked forward to {#blank#}10{#/blank#} (visit) my family in the summer vacation.

......I sat down on one of those chairs {#blank#}1{#/blank#} holes in it and waited. We had been in the hat shop for half an hour and my wife was still in front of the mirror.

"You {#blank#}2{#/blank#} buy things we don't need," I remarked suddenly. I {#blank#}3{#/blank#} saying it almost at once……
