Smiling is a universal language that everyone understands, no matter where they come from. Studies have shown that smiling has many benefits for our health. When you smile, your brain releases chemicals called endorphins. These are natural painkillers that also make you feel happier. Smiling can lower your stress levels and even boost your immune system. So smiling is not just good for your mind but also for your body. Smiling also helps you connect with others. When you smile at someone, they are likely to smile back. This creates a positive feedback loop that makes both of you feel better. In social situations, people who smile often appear more friendly and trustworthy. A simple smile can start a conversation or mend a broken relationship. However, some people find it hard to smile because they are going through difficult times. If you see someone who looks sad, offering a warm smile might be the first step to helping them feel better. Remember, you don't need a reason to smile. Sometimes the best time to smile is when you feel like you have nothing to smile about. 31．What happens when you smile according to the passage? A．Your brain releases chemicals that make you feel happier. B．Your stress levels increase. C．Your immune system becomes weaker. D．Your body feels more tired. 32．How does smiling help you connect with others? A．It makes you look more serious. B．It creates a positive feedback loop. C．It starts arguments. D．It makes people avoid you. 33．What is an endorphin? A．A type of disease. B．A natural painkiller released by the brain. C．A social skill. D．A kind of smile. 34．What should you do if you see someone who looks sad? A．Leave them alone. B．Offer them a warm smile. C．Tell them to cheer up. D．Ask them why they are sad. 35．What is the best title for this passage? A．How to Make Friends B．The Health Benefits of Exercise C．The Power of a Smile D．Ways to Reduce Stress 六、完形填空（每小题2分,满分12分） Do you often feel tired after staring at a screen for too long? You are not alone. Many students today spend hours each day on their phones, computers, or tablets. While technology brings us many 36 , it also has some negative effects on our health. One common problem is eye strain. When you look at a screen for a long time, your eyes have to work harder. This can cause headaches and dry eyes. To 37 this, doctors suggest the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Another issue is that too much screen time can affect your sleep. The blue light from screens can fool your brain into thinking it's still daytime. This makes it harder to fall 38 at night. Experts recommend turning off electronic devices at least one hour before bedtime. 39 , spending too much time online can also influence your mental health. Comparing yourself to others on social media might make you feel unhappy or lonely. It is important to remember that what people post online is not always the 40 picture of their lives. So what can we do? The key is to find a balance. Enjoy the benefits of technology, but don't forget to take breaks, go outside, and spend time with family and friends in the 41 world.

Digital maps have changed the way we travel and explore the world. Before smartphones, people used paper maps or asked strangers for directions. Now, with just a few taps on your phone, you can get step-by-step directions to almost anywhere. Digital maps are not just for driving. They can also help people who are walking, biking, or taking public transportation. Some map apps can even show you how crowded a bus or train is before you get on. This helps you save time and plan your trip better. Another great feature of digital maps is the real-time traffic information. If there is a traffic jam ahead, the app can suggest a faster route. This is very helpful for people who drive to work every day. Some apps can also tell you where to find the cheapest gas station nearby. However, digital maps have some disadvantages. They depend on the internet and GPS signals. If you are in a remote area with no signal, the map might not work. Also, sometimes the information on the map is not up to date. A new road might not appear, or a store might have moved. That is why it is still good to know how to read a paper map or ask for directions when needed. In the future, digital maps will become even smarter. They might use augmented reality (AR) to show directions directly on the real-world view through your phone's camera. Imagine seeing arrows on the street in front of you pointing the way! 42．How did people find directions before smartphones? _______________________________________________________________________________ 43．What can digital maps show about public transportation? _______________________________________________________________________________ 44．How do digital maps help drivers avoid traffic jams? _______________________________________________________________________________ 45．Why might digital maps fail to work in some places? _______________________________________________________________________________ 46．What technology might digital maps use in the future? _______________________________________________________________________________ 八、翻译（每小题2分,满分6分） 47．锻炼身体有助于保持健康。 _______________________________________________________________________________ 48．这个应用程序能提醒我按时吃药。 _______________________________________________________________________________ 49．我们应该把垃圾扔进垃圾桶里。 _______________________________________________________________________________ 九、书面表达（满分25分） 50．假设你是李华，你的学校上周举办了一场以“保护地球，从我做起”为主题的环保活动。你的笔友Mike对此很感兴趣。请你结合以下提示，用英语给他写一封信，介绍这次活动的内容以及你的感受。词数80左右。 注意事项： 1. 必须包含所提示的信息，可适当发挥，开头结尾已给出，不计入总词数； 2. 意思清楚，表达通顺，行文连贯，书写规范； 3. 请勿在文中使用真实的姓名、校名及地名。 提示： 1. 活动时间：上周六上午； 2. 活动地点：学校附近的公园； 3. 活动内容：清理垃圾、种植树木、制作环保海报； 4. 你的感受：……（至少两点） Dear Mike, I'm glad to hear that you are interested in the environmental activity in our school. _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ What do you think of this activity?

The activity was held last Saturday morning in the park near our school. All the students in my class took part in it. First, we picked up the rubbish on the grass and beside the roads. Then we planted some young trees. Finally, we made some beautiful posters about environmental protection and put them up in the park. I felt very proud because we did something good for the earth. I also realized that everyone can make a difference if we work together. It was a meaningful and unforgettable experience. What do you think of this activity? I'm looking forward to hearing from you.
