George tried to pull them out but didn’t succeed. When he got home, he put one of the burrs under his microscope and saw that it was covered in tiny hooks (钩) which made it so 2 to remove the burrs from his dog. This gave him the 3 , and soon Velcro TM strip was born. The potato chip was invented in 1853 by George Crum, a 4 who worked in a restaurant in America. One day, a customer in the restaurant sent back his plate of fried potatoes because they were cut too 5 . George was so angry that he cut a potato into very thin slices and fried them. Then he put lots of salt on them. He 6 that the customer would hate them, but the customer loved them and asked for more. The most 7 drink in the world, after water of course, is tea.

Its meaning comes from two important historical 1 in ancient China. During the Western Han Dynasty (202 BC–9 AD), Emperor Jingdi wanted to make the princes less powerful. This made seven princes very 2 . In 154 BC, they joined together to 3 the emperor. Their rebellion caused years of war, destroyed many cities, and left people’s lives in chaos. Although the emperor 4 won, the damage was huge. People later called this event “Luan Qi” (Chaotic Seven). Later, in the Jin Dynasty (266–420 AD), eight princes started fighting each other for power. This “Eight Princes’ Rebellion” 5 from 291 to 306 AD．The war burned villages, killed thousands of people, and made society fall apart. The word “Ba Zao” (Eight Troubles) became a 6 of long-lasting chaos. As time passed, people combined these two stories to 7 “Luan Qi Ba Zao”. They used it to talk about any situation that was as messy as these ancient wars. Today, we still use this phrase in daily life. For example: “My desk is a luan qi ba zao after studying all night!” This idiom shows how history can 8 language. By learning about “Luan Qi Ba Zao”, we not only understand a phrase but also remember the lessons from the past: fighting and chaos always bring suffering. For our junior students, learning idioms like “Luan Qi Ba Zao” is like opening a door to China’s rich history. When we understand their origins, we can discover more about history, appreciate our culture better, and 9 our language skills. In this way, idioms are like 10 between the past and the present. They help us feel proud of our cultural heritage while making learning interesting! 1．A．matters B．accident C．events D．activities 2．A．bored B．angry C．frightened D．embarrassed 3．A．fight for B．fight against C．protect from D．struggle against 4．A．eventually B．accidentally C．frequently D．suddenly 5．A．happened B．spread C．enlarged D．lasted 6．A．symbol B．review C．mark D．sign 7．A．invent B．discover C．create D．build 8．A．change B．choose C．decide D．influence 9．A．replace B．improve C．deepen D．renew 10．A．ways B．methods C．bridges D．paths In a small town in France, there was a farmer.

After he 4 it, he found that he wasn’t. He was very 5 and took the farmer to the judge (法官). The judge asked the farmer if he had any 6 to weigh the butter. The farmer replied. “I am so 7 that I do not have enough money to buy 8 to weigh it, but I have a kind of scale (天平).” The judge asked 9 , “Then how do you weigh the butter?” The farmer replied, “I will buy bread from the baker before he buys butter from me.

They were often the 1 of a room. And they were 2 programmed to do Maths problems. They were very important for businesses 3 they could work out very difficult problems again and again, without making mistakes. In the 1970s, there were 4 computers. People bought computers for their homes. The computers didn’t have a mouse, but the keyboard was used to 5 the computer what to do. When the 6 computer games were sold in the 1980s, people could use computers for 7 as well as for work. During the 1980s and 1990s, computers were sold with speakers and colour screens, and people could play more exciting 8 . In the 1990s, a revolution (大变革) in communication 9 . People could use computers to talk with family and friends, and businesses could sell products all over the world 10 and easily.

Many teachers are 1 of using PDAs in language learning. They say that students now have a lot more time for 2 in the classroom. 3 spending class time listening to texts or watching teaching videos, they can do these on their own and come to class prepared for discussion. The teachers also say that PDAs 4 students to learn without their teachers’ help. Some students might listen to a dialogue only once and understand it. Using PDAs is 5 helpful to students who are learning a language at their own speed. The students believe that using PDAs is a more 6 way to learn. The class has become much more interesting. By using PDAs, they can pay more attention to material and learn more. But many parents complain that technologies such as PDAs are 7 students. They worry that students might use them to cheat during exams. Some even argue (争论) that students may 8 old ways of learning and depend too much on technology. If a student spends more time watching video s on a PDA, he will have fewer 9 to have face-to-face communication with others. Education needs to make changes. We should look forward to a wonderful future when PDAs and other technologies can 10 a lot to the classroom. 1．A．providers B．officers C．characters D．supporters 2．A．discussion B．conversation C．advice D．homework 3．A．Because of B．Instead of C．With D．Through 4．A．advise B．allow C．manage D．ask 5．A．differently B．possibly C．especially D．recently 6．A．enjoyable B．classical C．smooth D．expensive 7．A．improving B．warning C．guiding D．harming 8．A．set up B．put up C．give up D．pick up 9．A．situations B．chances C．details D．purposes 10．A．organize B．see C．return D．add Unit 4单元话题 Many of the most useful things around us were invented by mistake, such as the Velcro TM strip (维可牢尼龙搭扣), potato chips and tea which were all accidents. The Velcro TM strip was 1 in Switzerland by a mountaineer called George de Mestral, and one day in 1948, when he took his dog for a walk, the dog picked up many burrs (芒). George tried to pull them out but didn’t succeed. When he got home, he put one of the burrs under his microscope and saw that it was covered in tiny hooks (钩) which made it so 2 to remove the burrs from his dog. This gave him the 3 , and soon Velcro TM strip was born. The potato chip was invented in 1853 by George Crum, a 4 who worked in a restaurant in America. One day, a customer in the restaurant sent back his plate of fried potatoes because they were cut too 5 . George was so angry that he cut a potato into very thin slices and fried them. Then he put lots of salt on them. He 6 that the customer would hate them, but the customer loved them and asked for more. The most 7 drink in the world, after water of course, is tea. It’s another common thing that was invented 8 . It was invented in China around 5,000 years ago by a Chinese emperor called Shen Nong. The emperor was boiling water to drink over an open fire when some leaves fell into the water from a nearby plant. The emperor 9 that the leaves in the water produced a pleasant smell. He tasted the hot water and found it was quite delicious. And this is the 10 that tea was invented. 1．A．used B．shared C．sold D．invented 2．A．nervous B．difficult C．dangerous D．boring 3．A．advice B．hope C．test D．idea 4．A．cook B．waiter C．cleaner D．manager 5．A．small B．big C．thick D．thin 6．A．thought B．regretted C．imagined D．explained 7．A．expensive B．popular C．interesting D．delicious 8．A．gradually B．directly C．accidentally D．suddenly 9．A．noticed B．ordered C．knew D．said 10．A．place B．plan C．time D．way Do you know the story of how Zhang Heng invented the Houfeng Seismograph? Let me tell you about it. Zhang Heng was a(n) 1 in the exploration of nature. He was 2 about nature from a young age. He also showed a great 3 for studying nature. In ancient China, earthquakes happened often. 4 , people didn’t know how to deal with the problem. When Zhang Heng saw that many people were hurt, he decided to 5 something to help people predict (预测) the disaster. He spent lots of time researching earthquakes. He carefully studied and 6 historical records of earthquake events, and finally he developed the Houfeng Seismograph. Although the seismograph wasn’t 7 at first, it brought great help to people’s lives. It helped people detect (发现) earthquakes early. The story of Zhang Heng not only shows the importance of creativity, but also has 8 many scientists to work hard for science. Zhang Heng’s deep respect for nature and truth in science was one of his important 9 . Today, if we visit the museum, we need to buy a 10 to see a copy of the Houfeng Seismograph and learn about this great invention and other inventions. Zhang Heng really left behind priceless inventions in Chinese history. 1．A．pioneer B．engineer C．musician D．artist 2．A．angry B．nervous C．happy D．curious 3．A．rule B．talent C．mistake D．secret 4．A．Again B．Instead C．However D．Besides 5．A．save B．create C．repeat D．realise 6．A．analyzed B．received C．carried D．connected 7．A．important B．delicious C．balanced D．perfect 8．A．introduced B．improved C．influenced D．described 9．A．qualities B．suggestions C．thoughts D．risks 10．A．book B．ticket C．stamp D．map Most people have dreams in life. A right 1 can make a person keep learning and improving. For me, I want to 2 a robot engineer. This has something to do with my father. He works in a food factory. Years ago, my father broke his left leg when he was working in the 3 . He needed to have an operation (手术) at once. Some doctors in my town told my family to take him to a city hospital, 4 the doctors in the town were not able to do the operation. The situation (情况) was 5 . We needed to be quick, or my father would 6 lose his leg. Finally, it took us an hour to reach the city hospital. Doctors there said my father was lucky to get there in time. After that, I 7 problems in health care in our country. I decided to become an engineer. I want to create a 8 that can act as a doctor. Even if it can’t do the difficult operation by itself, the doctors far away can guide it through the internet. Then it can finish the operation well. It may sound impossible, but I 9 robots can do this in the future. Like my town, many places don’t have doctors who can do difficult operations. So it’s 10 to improve the situation. I hope I can bring something helpful to our country. 1．A．dream B．promise C．reason D．experience 2．A．touch B．choose C．become D．focus 3．A．school B．factory C．library D．farm 4．A．because B．if C．but D．although 5．A．fresh B．lucky C．simple D．dangerous 6．A．quietly B．clearly C．probably D．finally 7．A．thought about B．brought out C．took up D．looked after 8．A．tool B．glove C．phone D．robot 9．A．wonder B．agree C．believe D．explain 10．A．similar B．necessary C．serious D．bright 学科网（北京）股份有限公司 $
