It was such a beautiful day that I drove to go for a look in the country. On the way back home, my car stopped. It was out of gas on a lonely road far from a town. I decided to walk until I found someone who could sell me gas. I had walked almost a mile before I finally found a house near the road. I was glad to see it, because it was getting dark. I knocked at the door and a little old lady with long white hair answered. She said, “I’ve been waiting for you for a long time. Come in. Tea is almost ready.” “But I only come for some gas,” I answered. I couldn’t imagine what she was talking about. “Oh, Alfred! Gas? You used to like tea.” I quickly explained that my car was out of gas, but she didn’t seem to hear me. She just kept calling me Alfred and talking about how long it had been since she had seen me. She was acting very strangely and I was anxious (急切的) to leave. As soon as she went to get tea, I went out of the house as fast as I could. Fortunately, there was another house down the road and I was able to buy the gas I needed. When I told the man about my experience, he said, “Oh, that’s Miss Emily./She lives by herself in that big house. She’s strange but she wouldn’t hurt anybody. She is still waiting for the man she was going to marry thirty years ago. The day before their Wedding he left home and never came back because of the war.” 36．What does the underlined word “it” in Paragraph 3 refer to in the passage? A. The road. B. The house. C.

Paper, sticks, glue and string are all you need. Put them together to build a kite. A kite connects you to the past. No one knows who flew the first kite. It was probably someone in China or perhaps Indonesia. Indonesian fishermen hung fishhooks on kites and sent them out to sea to catch fish. Starting 2,000 years ago, Chinese farmers flew kites to welcome the New Year and bring good luck to Earth. In China, people also used kites during wartime. One Chinese story tells how soldiers put noise makers on kites and flew them all night over the enemy camp. The enemies were frightened by the noise and ran away. About 1,300 years ago, Chinese travelers took kites to Japan. Soon kites filled the skies there. Kites reached Thailand about 700 years ago. During floods, Thai farmers flew kites over their fields. They hoped the kites would drive away the clouds and stop the rain. Over time, kites flew their way out of Asia. Today, kites are a passion all over the world. Kite fans meet at festivals in many parts of the world and have great fun. Over the years, Kites have also helped people understand the natural world. In 1749, for example, thermometers were tied to kites to measure temperatures. In 1906, cameras hanging from kites took pictures of San Francisco, California after an earthquake. The photos helped people plan what to do. Kites also helped inventors find out how to make airplanes. The Wight brothers studied how kites flew, which helped them make the first successful airplane. Since the ancient Chinese first set their kites into the air, people have loved flying kites. Kites give us ways to celebrate, relax and explore. So go fly a kite! Enjoy the feeling of wonder that kite flyers have felt for centuries. 41．According to the passage, in which countries were kites used to make good wishes? A. China and Japan. B. China and Thailand.

If you arrange the 26 English letters alphabetically (按字母表的顺序) and use numbers to represent (代表) each of them, for example, 1 for a, 2 for b, 3 for c..., you can change an English word into a number, so hard work becomes 8+1+18+4+23+15+ 18+11= “98,” meaning 98 is its mark; Knowledge: 11+14+15+23+12+5+4+7+5= “96,” while love: 12+15+22+5= “54,” and luck: 12+21+3+11= “47,” a small mark. None of these words can give one a full mark. What about money or prayer(祈祷)? They can’t, either. Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude(态度). Yes, attitude is the word. See for yourself: attitude: 1+20+20+9+20+21+4+5=100, a full mark. Different attitudes lead to different courses of life. Most times people hope for a better life. It is possible that one will have a change for the better after one has changed one’s attitude. When you change your manner and become friendly towards others, you’ll meet more smiling faces towards you. In the same way, if you take a positive attitude towards failure (失败), you’ll find it’s also rewarding (值得的) though it has caused you losses. 46．In the writer’s opinion, what is the most important thing in a person’s life? A. Hard work B. Knowledge C. Money D. Attitude 47．According to the passage, what’s the mark of the word “succeed”? A. 50 B. 60 C. 70 D. 80 48．What does the underlined word “positive” mean in the text? A. 正极 B. 负极 C. 积极的 D. 消极的 49．According to the passage, if you meet with problems, the best way out is to __________. A. change your attitude B. say your prayers to God C. ask for help from others D. try math-solving methods 50．From the passage we can learn that __________. A. Different attitudes come from different courses of life. B. Mathematics (代数) can solve every problem easily in our daily life. C. Failure sometimes can bring you good if you take a positive attitude. D. None of the English words except “attitude” equals to 100 or more. 第二节 阅读填空（共5小题；每小题1分，满分5分） 阅读短文及文后A～E选项，选出可以填入51～55各题空白处的最佳选项，并在答题卡上将该项涂黑。 When mobile phones first appeared in the early 1990s, they were symbols of wealth for business people. At that time, phones were heavy and expensive, and the signal (信号) was usually poor. 51 In many rich countries, the mobile phone became the teenagers’ favourite toy. In just 20 years, mobiles have changed the way people do business and socialize (交际) in rich countries. 52 In Africa, the arrival of inexpensive mobile phones has already helped many people to start small businesses. Before mobile phones, starting a business often meant renting(租用) a shop or an office, which was expensive. 53 Now business owners can write their mobile number on an advertisement, put it on a notice board and wait for customers to call them. As a result, thousands of people can find a market for their products or services. 54 A few calls on their mobile phones can tell them where their fish are needed most. Farmers, too, are using mobile phones. Around the world, new mobile services provide local weather information to help them plan their work. 55 As mobile phones make business easier, they improve living conditions for hundreds of thousands of people around the world. And as they spread and get more popular, it seems that they are changing the world in ways we can’t fully imagine. A. If customers came when the owner was out, business was lost. B. Over the next ten years, technology improved and prices fell greatly. C. Nowadays, mobile technology is having a great influence on poor countries too. D.

Digital life is a double-edged sword. On one hand, it brings incredible convenience. We can connect with friends and family worldwide instantly, access vast information for learning, and enjoy various forms of entertainment. On the other hand, over-reliance can be harmful. Too much screen time may lead to health issues like eye strain and sleep problems. It can also reduce face-to-face interaction and raise privacy concerns. In essence, digital life itself is neither entirely good nor bad. Its value depends on how we use it. The key is to find a healthy balance, leveraging its benefits while avoiding its pitfalls to enhance our real-life experiences. $
