At 12:00,Wilbur flew it 852 feet in 59 seconds! Johnny Moore,one of the five men who 9 them that morning (in charge of dragging the plane across the sand for positioning),ran to the village of Kitty Hawk crying,“They’ve made it!” This was the 10 of aviation!

The discovery of 19 detailed circuit diagrams (电路图)of the computer was an unexpected surprise — the engineers had been depending on pictures to help them with the rebuilding.Now, there is more good news for the EDSAC team. When Robert Little read about the EDSAC project, lie realized he had a small part of this computer in his garage. Little had gained it in 1969 from Dr. Robert Clark — a scientist at Cambridge, Massachusetts, who was using the EDSAC rack (架子) as a bookshelf! Robert has given his EDSAC rack to the British team and they are trying to combine this original piece into their design.EDSAC was built by a team led by Sir Maurice Wilkes. Wilkes was inspired bythe theories of John von Neumann, an intelligent mathematician. In 1945, Neumann had suggested that the future of computing lay on computers that could store instructions (programs) and data.EDSAC first appeared in 1949. It was a little over 6 feet tall and. took up the space of 13 * 16 square feet room. It performed 650 instructions per second, while today’s computers like the Intel i7 can do 92 billion instructions per second!At the heart of computers are hundreds of millions of tiny electronic devices called transistors. Like your brain cells, these transistors control the computer’s operation. Each transistor can be in one of the two states — either ON or OFF, depending on what the program asks it to do. But before transistors came along, scientists had to use vacuum tubes to do the same — turn ON or OFF.Vacuum tubes are nothing but glass bulbs with air removed, creating a vacuum. Three plates inside this bulb control the flow of the current(气流)to put this bulb in ON or OFF slate. The EDSAC team is using them to rebuild the first computer.1. According to the Lex I, Robert Lillie ________.A. found 19 detailed circuit diagrams unexpectedlyB. played an important role in rebuilding EDSACC. used the EDSAC rack as a bookshelf himselfD. left the EDSAC rack alone in his garage2. We can infer that EDSAC ________.A. was the first computer for common useB. was specially designed for the purpose of the armyC. was able to calculate faster than modem computersD. was the firs I computer made in 19493. We can infer that Neumann ________.A. guided the process of building EDSACB. laid a basis for computers in theoryC. was the first scientist to store data in the computerD. took the lead in using computers to calculate4. What does the underlined word "them" refer to?A. The current flows.B. Electronic devices.C. The vacuum tubes.D. Transistors.5. Where can we most likely read the text?A. In a personal diary.B. In a travel journal.C. In a geography book.D. In a science magazine.三、语法填空阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

air quality in the city has improved over the past two months.It is shown in the report.五、阅读理解More than 2,000 years ago,when the last shovelful(一铲) of dirt fell on the Terracotta Warriors,it was thought that they would never see the sunlight again and would spend the rest of their “lives” guarding and protecting the first Chinese emperor,Qin Shi Huang,who died in 210 BC.But things got better off these clay (陶土的) soldiers.Ever since they were discovered in Xi’an in 1974,by a group of farmers;they’ve been able to see the bigger world—traveling from one museum to the next.They are now on display in New York at Discovery Times Square,reported The New York Times.However,the story doesn’t end here.The roughly 2,000 soldiers found so far are estimated(估计) to be only one quarter of the total number.Moreover,scientists haven’t yet dared to touch the central tomb,which is believed to contain the body of the emperor himself.“Partly it’s out of respect for the elders,” explained Kristin Romey,consultant(顾问) for the exhibition.“But they also realize that nobody in the world right now has the technology to properly go in and excavate(挖掘) it.”This is true.According to ancient writings,the emperor’s tomb is circled by rivers of liquid mercury(水银) which is highly poisonous but can keep the body in good condition.Studies of the soil around the tomb also found a large amount of mercury.This makes exploring the tomb very dangerous.The other reason that scientists have been hesitating is that they are afraid of the damage they might cause by opening the tomb.“When we began excavating ‘the soldiers’,the minute they were exposed to air and sunlight,the pigment(颜料) just flaked off (剥落),” Romey told the Fox News.But he believes that the solution will come when science advances.Perhaps a visual robot can be sent into the tomb first to investigate and help figure out the best way to protect it.In the end,scientists and historians must weigh their desire to know against the damage their digging might cause.“Archaeology,ultimately (最终),is a destructive science,” Romey said.“You have to destroy stuff in order to learn about it.”1.What is the point of the article?A.To tell about the mysteries of Qin Shi Huang’s tomb.B.To analyze why archaeology is a destructive science.C.To introduce the Terracotta Warriors exhibition in New York.D.To explain the risks of further excavating Qin Shi Huang’s tomb.,以及这其中的风险所在,所以答案为D项。
