根据《山东省高速公路命名和编号规则》规定，青兰高速编号为“G22”；同三高速编号为“G15”，并改名为“沈海高速”；荣乌高速编号为“G18”，其中荣乌高速支线青岛段编号为“S24”，“截至去年底，我们已经对以上高速公路进行了更名，并更换了新的路标。
”市公路局相关工作人员表示。
同时，山东高速公路股份有限公司青岛分公司相关工作人员表示，目前济青高速公路很多地方已经悬挂上“G20”标识，但是具体路牌更换工作都是山东高速集团在做，而根据去年版的《国家高速公路网路线命名和编号规则》，济青高速属于青银高速的一部分，编号为G20。

青岛胶州湾跨海大桥和海底隧道
山东省青岛市郊洲湾跨海大桥长度41.52公里世界之最Jiaozhou Bay Cross-sea Bridge, Qingdao, Shandong. Length 41.52 km, World’s LongestJiaozhou Bay山东青岛胶州湾大桥Jiaozhou Bay Bridge, Qingdao, Shandong中新社青岛2011年6月30日电(修建华李英胡耀杰)世界最长跨海大桥—青岛胶州湾大桥30日上午10时8分在此间正式通车。
据悉，该桥全长41.58公里，东起青岛主城区，跨越胶州湾海域，西至黄岛，是中国国家高速公路网山东青岛到甘肃兰州高速公路的起点段。
该桥为双向六车道，设计车速为80公里/小时，桥梁宽度35米，设计基准期为100年。
大桥主体包括沧口、红岛和大沽河三座航道桥、海上非通航孔桥和路上引桥以及管理设施，总投资逾100亿元人民币。
据青岛胶州湾大桥总工程师邵新鹏介绍，该桥不仅是目前世界上最长的跨海大桥，同时也是中国北方首座冰冻海域特大型桥梁。
在大桥的建设过程中涵盖了目前世界上许多最先进的建桥工艺和技法，填补了中国桥梁史上多项空白，如作为该工程主体部分的红岛互通立交桥是中国首座海上立交桥，代表了中国海上桥梁建设的最先进水平，其移动滑移模架在国际业界属于首创。
据介绍，该桥所连接的青岛、黄岛、红岛三地不仅居于山东半岛的核心咽喉部位，而且处在山东的命脉胶济铁路城市带上。
该桥建成后，不仅终结了青岛与其所辖国家级经济技术开发区黄岛区“青黄不接”的历史，开启了青岛与其卫星城区同城化的新时代，同时将极大完善山东半岛交通网络，促进山东半岛城市经济一体化发展。
HongdaoQingdaoCity Huangdao、BEIJING -Thursday, 30 June 2011, China has opened the world's longest cross-sea bridge.The Jiaozhou Bay bridge is 26 miles (42 kilometers) long and links China's eastern port city of Qingdao to an offshore island, Huangdao.CCTV says the 110-foot (35-meter)-wide bridge is the longest of its kind and cost more than 10 billion yuan ($1.5 billion). CCTV also says the bridge passed construction appraisals on Monday and the bridge and an undersea tunnel opened to traffic on Thursday.It has taken four years to build the bridge, which is supported by more than 5,000 pillars.According to Guinness World Records, the previous record holder for a bridge over water is the Lake Pontchartrain Causeway in Louisiana. The Chinese bridge is more than 2.5 miles (4 kilometers) longer.This photo taken on Wed. June 29, 2011 shows the Jiaozhou Bay Bridge in Qingdao, east China's Shandong Province. On Thu. June 30, 2011, China opened the world's longest cross-sea bridge, which is 42 kilometers (26 miles) long and links China's eastern port city of Qingdao to an offshore island, Huangdao.

[Photo/Xinhua]Have you noticed how the landmark technologicalmarvels are shifting one by one to the rising SuperPower China?After longest rail lines and fastest rails it is now time for the longest bridge. This phenomenon is perhaps synonymous with a nations progress and development!The Lake Pontchartrain Causeway in Louisiana, which had the title until December 27 of the last year, for its longest span, has now been dwarfed by three miles, by the new bridge that has a massive 26.4 miles span–five miles more than the distance between Dover and Calais. Expressing in another way, the Qingdao Haiwan Bridge is 174 times longer than the famous London’s Tower Bridge over the river Thames.A band plays during the opening ceremony of the Qingdao Jiaozhou Bay Bridge in Qingdao, Shandong province Thursday June 30, 2011.集团公司董事长孙亮在通车典礼仪式上致辞2011年6月30日，电视记者在青岛胶州湾大桥红岛互通立交上现场报道。

We travelled all the way from California to Las Vegas. I noticed something funny about the way everyone spoke English. I was thinking, “This is the way they speak in films!”At the beginning of the holiday, one of my friends asked me if I wanted to order “French fries.” I couldn’t imagine what French fries were. What was fried and French?! Snails? Cheese? She was amazed that I had never tried them and she ordered a portion for us to share. When the waiter brought us some chips, I asked her where the French fries were. She pointed to the plate of chips! Later that week she said she was going to buy some “chips” from the supermarket. She came out with a packet of crisps!During that holiday we were also offered “biscuits and gravy” with our lunch. This was a very strange idea to me, because in England biscuits are sweet. Gravy is a salty, meat-based sauce. I later realized that “biscuits” in America are savoury snacks. What we call “biscuits,” they call “cookies.”One day, I saw an “eggplant” pizza on the menu in a restaurant! Eggs do not grow on plants, I thought. What on earth could an “eggplant” be? Something eggy and leafy? My dad ordered this pizza and it was covered in aubergines. I asked him where the “eggplant” was. He laughed and pointed to the aubergines. He told me, “They call this ‘eggplant’ in America!”Although the same “language” may be spoken in different countries, there are likely to be many differences, not just in vocabulary but also in spelling, grammar and pronunciation! I think part of the excitement of learning a language is discovering the differences in how it is spoken in different places.4．What can we learn from paragraph 2?A．Holiday is a good time to relax.B．French fries are popular worldwide.C．The waiter provided poor service.D．Chips and crisps are the same food. 5．Where does the author most probably come from?A．America.B．France.C．England.D．Italy.6．How did the author feel when seeing an “eggplant” pizza on the menu?A．Excited.B．Regretful.C．Anxious.D．Confused. 7．What is the text mainly about?A．Advantages of travelling.B．High-end restaurants.C．Food and tradition.D．Cross-cultural misunderstanding.In the west of the Greek capital Athens, the fish market of Keratsini is busy early in the morning, with trucks waiting nearby to be loaded with fishes. But on his fishing boat, Arapakis sorts out something different—bottles, boots, plastic pipes and fishing nets, all dragged from the bed of the Aegean Sea.“We are swimming in plastic,” said Arapakis, whose family has fished for five generations. “By 2050, there will be more plastic than fish in the sea,” he said, as recent reports noted.That morning’s plastic catch weighed “about 100 kilograms,” said the founder of Enaleia, a nonprofit that encourages fishermen to collect marine (海洋的) waste caught in their nets. Since its establishment in 2018, it has worked with more than 1,200 fishermen in Greece to raise concern over the degradation of the marine environment.Active in 42 ports throughout Greece, Enaleia provides fishermen with large bags for marine waste that they can put in garbage cans once back at port. For every kilogram of plastic they deliver, they receive a small amount of money, which is enough for a drink. Since October, fishing crews have dragged out 20 metric tons of plastic and old fishing equipment each month. Nearly 600 tons have been collected over the last five years. The collected plastic is transported to a recycling plant in the industrial area of Megara near Keratsini, to make new products such as socks, swimwear or furniture.Arapakis said he went about the cleanup project after a trip to Greece’s Cyclades islands, where he saw fishermen throwing the waste gathered by their nets back into the sea.Arapakis is convinced there has been a “mentality change” among Greece’s fishermen. “Previously we caught large quantities of plastic, but we only kept the fish. All waste wasthrown into the sea,” said Mokharam, team leader on the Arapakis family’s boat. “The project brings practical benefits for fishing boats. In the past, the anchor was often caught by waste, especially nets, and the engine would go out. But now things have changed,” he added. 8．What can we learn about Arapakis from the first 2 paragraphs?A．He was a successful fish trader.B．He collected waste from the sea.C．He liked swimming in the sea.D．He had a large family to support. 9．What does the underlined word “degradation” in paragraph 3 mean?A．Impact.B．Worsening.C．Improvement.D．Research. 10．What will most probably happen to the collected waste in the end?A．It will be sold at a high price.B．It will be exchanged for food.C．It will be thrown back into the sea.D．It will be well dealt with for reuse. 11．What can we infer from Mokharam’s words?A．Fishing is a tough job for fishermen.B．The sea in Greece is seriously polluted.C．He thinks highly of the cleanup project.D．He still feels ashamed for fishermen’s behavior.Anyone who’s lived through middle school knows those years can be particularly challenging. Some researches show youths across the U.S. are struggling with mental health. The physical health benefits of bike riding have been well-documented. Wilson, a researcher at Loma Linda University School of Medicine, and his co-authors carried out a new study to see if taking part in a cycling program could result in measurable changes in mind for teenagers.The study involved more than 1,200 students, ages 11 to 14. Students participated in a cycling class for at least three days a week, for a period of 6 weeks. They learned cycling safety and practicing skills outdoors while raising their heart rate and just having fun. The students completed standardized questionnaires before and after the program designed to measure their health.“We know cycling can benefit the body. Our research shows how it benefits the mind and social relationships as well. Bike riding can be an ideal activity for adolescents because of the benefits it offers,” said Wilson.“Cycling engages several parts of brain function. You are looking at your hearing, you’re balancing, you’re navigating and turning. Oftentimes, you’re doing it with someone else, sothere’s the positive effect of company or group activity,” said Allan Reiss, a professor at Stanford University School of Medicine.While exercise has powerful mental health benefits, it’s not universal. For example, previous research has shown that teenage girls are at higher risk of mental health problems like depression and anxiety than boys. The current study found that, while middle school girls reported increased well-being after participating in the cycling program, that increase “may just reach the kind of baseline level for male students,” Wilson said. And other aspects of healthy living are also important, noted Wilson. The study found that teenagers who didn’t limit screen time to a maximum of two hours a day, or who got less than the recommended 8.5 hours of sleep, saw less improvement in their well-being, he said.12．What does the new study mainly focus on?A．Challenges in middle school.B．Youths in America.C．Physical benefits of cycling.D．Mental effects of bike riding. 13．What did the students do in the program?A．Attend the cycling class for a week.B．Learn how to keep safe while cycling.C．Raise their heart rate by cycling indoors.D．Design questions to measure their health.14．What is Reiss’s attitude to the result of the study?A．Supportive.B．Doubtful.C．Unclear.D．Negative. 15．What is the last paragraph mainly about?A．Application of the research results.B．Doubts about the research methods.C．Further explanation of the research findings.D．Supporting evidence from previous research.二、七选五stronger our relationships are, the more likely we are to live better. So how do we deepen friendships in our lives?Shower them with affection. We often think of affection as love we show in romanticrelationships. But affection is more than holding hands and kissing. 17 There are many ways you can show love to your friends. Tell them how much they mean to you. Remind them you are grateful to know them. These simple acts provide security in the relationship.18 Being generous with your friends is an easy way to develop your friendships. If you’re a gym rat, you could help your friend train for a coming race they have. Or if your friend is applying for a university, you can use your research and analysis skills to put together a presentation for them.Share your joys, struggles and even guilt. Think about how good it feels to tell a friend you secretly like a boring TV show and hear them respond “me too!” 19 Many people hold the view that it can be scary to be open with our feelings. It can come with the risk of shame or rejection. But people are less likely to reject you for being weak than you think.Don’t hide your disagreements. It’s hard to deal with conflict in friendships. People often see them as something that should be fun and lighthearted, so they ignore problems when they arise. 20 It might be painful at first, but it shows you want to be honest with them, and that you want to make your relationship better.A．Tell them how much you value them.B．Value them with your skills and talents.C．It’s about communicating love and appreciation.D．In fact, it’s linked to our mental and physical health.E．It means they accept us for who we are, the good and the bad.F．People feel hurt when someone doesn’t keep their private information.G．But dealing with conflict in a healthy way can deepen your friendships.三、完形填空For the past four years I had been having up to 30 seizures (癫痫发作) a day. It made medown.One day, my friend Kerri asked if I wanted an assistance dog. I knew there were guide dogs for the 25 , but I wasn’t sure how a dog could help me.

Here is 21 schools and parents can help their children to develop their creativity.Drew worked for a company in 1925. At work he invented a kind of material strong enough to hold things together. But his boss told him 22 more about the idea. Drew didn’t stop and finally, using his own time, made a kind of tape, which now is used everywhere by many people. And his company learned from its 23 . Now the company asks its workers to spend 15 percent of their work time just 24 and developing new ideas.Creativity is not something one is just born with. A person with high intelligence does not mean that he uses it creatively. Creativity is the matter of 25 your intelligence to think of new ideas that are good for something.We know that many schools have tried to develop students creativity, but some teachers only want to develop students’ reading, writing and math skills, and have to 26 creativity for correct answers. Children from such schools can give correct answers, but they are unable to use 27 to work out problems.It is important to give children 28 . From the earliest age, children should learn to make decisions and understand their result. Even though it’s choosing between two kinds of food 29 lunch, decision-making helps thinking skills.

His most famous book, The Very Hungry Caterpillar, is popular all over the world. What most people don’t know is that Eric makes art for adults (成人), too. “ArtArt” is one of Eric’s works for adults.Like Eric’s children’s books, his “ArtArt” is full of colors. He says that he loves color so much because he missed it in the war (战争) in Germany. Eric was born in New York in 1929, but moved to Germany with his family when he was six. When he was 10, World War II started. Eric found people painted all the houses in his town gray, brown, or dark green. It seemed like there was no color anywhere. At the end of the war, “when color came back,” Eric said, “I just loved it so much. I keep saying that I wish our eyes could see more color. Color is very important in my work.”Anyone who has seen Eric’s books can see how important color is to the artist. He paints colors on a piece of paper (一张纸), cuts out shapes (形状), and then glues (粘贴) them onto another piece of paper. This is a special method. Eric used it in his “ArtArt”.“ArtArt” has paintings, photos and even clothes. In all these works, he uses different colors from purple to green to orange.36．What do we know about Eric’s The Very Hungry Caterpillar?A．It’s his first book.B．He wrote it in the war.C．He wrote it in New York.D．It’s his best-known book.37．When did Eric move to Germany?A．In 1929.B．In 1935.C．In 1939.D．In 1945. 38．What does the underlined word “it” refer to?A．Color.B．Work.C．The town.D．The house. 39．What does the underlined word “method” mean in Chinese?A．评论B．体验C．研究D．方法40．The writer mainly wants to tell us about ________.A．Eric’s dream B．Eric’s early lifeC．one of Eric’s works for adults D．one of Eric’s works for children阅读下列短文，从六个选项中选出五个最佳选项填入横线中。
