Every year it receives more than 750,000 visitors. People like to go to this place especially in June as they want to see the sun rising on the longest day of the year.For many years, historians believed Stonehenge was a temple where ancient leaders tried to communicate with the gods. However, historian Paul Stoker thinks this can’t be true because Stonehenge was built so many centuries ago. “The leaders arrived in England much later,” he points out.Another popular idea is that Stonehenge might be a kind of calendar. The large stones were put together in a certain way. On midsummer’s morning, the sun shines directly into the center of the stones. Other people believe the stones have a medical purpose. They think the stones can prevent illness and keep people healthy. “As you walk there, you can feel the energy from your feet moving up your body,” said one visitor. No one is sure what Stonehenge was used for, but most agree that the position of the stones must be for a special purpose. Some think it might be a burial place, or a place to honor ancestors. Others think it was built to celebrate a victory over an enemy.Stonehenge was built slowly over a long period of time. Most historians believe it must be almost 5,000 years old. One of the greatest mysteries is how it was built because the stones are so big and heavy. In2001, a group of English volunteers tried to build another Stonehenge, but th ey couldn’t. “We don’t really know who built Stonehenge,” says Paul Stoker. “And perhaps we might never know, but we do know they must have been hardworking ---- and great planners!”要点详解1.Why do you think the man is running?本句由“疑问词+do you think+其他”构成的特殊疑问句。

初中英语辅导材料
初中英语辅导材料Unit 1 - Greetings and IntroductionsLesson 1: Hello!In this lesson, we will learn basic greetings and introductions in English. Greetings are essential in daily conversations, as they help in establishing a friendly atmosphere. Let's start with the most common greeting, "Hello!" It is used to say hi or to start a conversation with someone. You can also use "Hi" or "Hey" as informal alternatives.Lesson 2: Introducing YourselfIn this lesson, we will focus on introducing ourselves. When meeting new people, it is important to be able to introduce yourself in English. You can start by saying your name, followed by a simple phrase like "Nice to meet you" or "Pleased to meet you." For example, "Hello, my name is Jane. Nice to meet you."Lesson 3: Asking and Answering QuestionsIn this lesson, we will learn how to ask and answer simple questions about personal information. You can ask questions like "What is your name?" or "How old are you?" When answering, remember to use complete sentences, such as "My name is John" or "I am thirteen years old."Lesson 4: Practice TimeNow it's time to practice what you have learned so far. Find a partner or use a mirror to have mock conversations. Take turns introducing yourselvesand asking each other questions. Remember to use proper greetings and responses, and try to incorporate the vocabulary from the previous lessons.Unit 2 - Daily ActivitiesLesson 1: Daily RoutinesIn this lesson, we will learn how to talk about daily activities. Daily routines include actions that we do every day, such as getting up, brushing our teeth, or going to school. You can use phrases like "I wake up at 7o'clock" or "I have breakfast at 8 o'clock" to describe your daily routine.Lesson 2: Time ExpressionsIn this lesson, we will focus on using time expressions to talk about daily activities. Time expressions help us specify when we do certain actions. Examples include "in the morning," "in the afternoon," "in the evening," "at night," and specific times like "at 7 o'clock" or "at noon."Lesson 3: Describing ActivitiesIn this lesson, we will learn how to describe activities using adverbs and adjectives. Adverbs describe how an action is done, such as "quickly," "carefully," or "happily." Adjectives, on the other hand, describe the quality or state of something, like "interesting," "boring," or "fun."Lesson 4: Practice TimeNow it's time to practice talking about daily activities. Think about your own routine and try to describe it using the vocabulary and expressions you have learned. You can also ask your friends about their daily activities and have a conversation discussing your schedules.Unit 3 - Free Time and HobbiesLesson 1: Leisure ActivitiesIn this lesson, we will explore leisure activities and hobbies. Free time is important for relaxation and pursuing our interests. Common leisure activities include reading books, playing sports, watching movies, or listening to music. Let's learn how to express our hobbies in English.Lesson 2: Expressing PreferencesIn this lesson, we will learn how to express our preferences for different activities. You can use phrases like "I like," "I love," or "I enjoy" followed by the name of the activity. For example, "I like playing basketball" or "I enjoy reading novels."Lesson 3: Talking about FrequencyIn this lesson, we will focus on expressing how often we do certain activities. You can use adverbs of frequency like "always," "often," "sometimes," "rarely," or "never" to describe the frequency of your hobbies. For example, "I often play video games" or "I rarely go swimming."Lesson 4: Sharing HobbiesNow it's time to share and discuss your hobbies with others. Practice having conversations about your favorite activities, and ask your friends about their hobbies as well. This will help you not only improve your English but also discover new hobbies and interests.Conclusion:These materials provide a comprehensive guide to assist middle school students in learning essential English language skills. Greetings, introductions, daily activities, and hobbies are crucial aspects of daily communication. By mastering these topics, students will have a solid foundation for further English language learning and be able to confidently engage in conversations. Regular practice and conversation with peers or teachers will greatly enhance their proficiency in English.。

So life today is easier than it was hundreds of years ago, but it has alsobrought new problems. One of the biggest is pollution. Pollution comes in many ways. We see it, smell it, drink it and even hear it.The more people, the more pollution. Years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world.Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our water. Noise pollution makes us become angry more easily. The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. We are sure if there are fewer people driving, there will be less air pollution.Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city. So the less pollution there is, the better life people will have.1. Why is the world becoming smaller?A. Because there are fewer people.B. Because of science development.C. Because the earth is polluted.D. Because of the rise of sea level.2. What was life like hundreds of years ago?A. It was harder than it is today.B. It was as easy as it is today.C. It was easier than it is today.D. It was as hard as it is today.3. There are kinds of pollution. The underlined(下划线的) word “it”in Paragraph One refersto_____pollution.A. noiseB. airC. waterD. light4. Why is air pollution the most serious kind of pollution?A. It makes much noise.B. It has made our rivers and lakes dirty.C. It’s bad to all living things in the world.D. It makes us hard to breathe.5. Which of the following is TRUE according to the passage?A. All countries are making rules to fight pollution.B. The pollution of the earth grows as fast as the world’s population does.C. The problem of pollution is not so serious because there are so many people.D. None of the above.BA kind of little cars may take the place of today’s big ones many years later. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will be less crowded.The little cars of the future will cost less. Driving will be safer, too, as these little cars can go only 65 kilometers an hour. The cars of the future will be fine for going around a city, but they’ll not be useful for a long way. Little cars will go 450 kilometers before they need to stop for more gasoline (汽油). If big cars are still used with the small ones, two kinds of roads will be needed in the future. Some roads will be needed for the big, faster cars and other roads will be needed for the small, slower ones.根据短文内容，选择正确的答案。
