I understand how you feel, as I once had similar experiences. Here are some suggestions that might help you. First, try to be more confident. When you meet new people, smile and make eye contact. People are usually attracted to those who appear friendly and confident. Don’t be afraid to start a conversation. You can begin with simple topics like school, hobbies, or recent movies. Second, join clubs or activities that interest you. This is a great way to meet people who share your interests. Whether it’s a sports team, a music club, or a reading group, you’ll have something in common with others right away. Shared interests make conversations easier and friendships develop more naturally. Third, be a good listener. Show genuine interest in what others say. Ask questions about their experiences and opinions. People appreciate when others listen to them attentively. Remembering details about their lives and following up in later conversations shows that you care. Finally, be patient. Making good friends takes time. Don’t expect to become best friends with someone immediately. Start with small steps and let friendships develop naturally. Be yourself, because true friends will like you for who you are. I hope these suggestions are helpful. Remember, many people feel lonely at times, but with a little effort, you can build meaningful friendships. I believe you’ll soon find good friends who appreciate you. Please keep me updated on your progress.

Friends are people who share our joys and sorrows, help us when we are in trouble, and make our lives more 21______. But what makes a good friend? I think a good friend should be honest. Honesty is the most important quality in a friendship. A true friend will tell you the truth even when it’s 22______ to hear. They won’t lie to you or talk about you behind your back. A good friend should also be 23______. They should care about your feelings and be there when you need them. If you have a problem, a caring friend will listen to you and try to 24______ you. It’s also important for friends to have similar interests. When you enjoy doing the same things, you can have more fun together. For example, if you both like sports, you can play basketball or go swimming together. If you both enjoy reading, you can 25______ books and discuss them. However, good friends don’t have to be exactly the same. In fact, sometimes it’s 26______ to have friends who are different from you. They can help you see things from a different perspective and 27______ you new things. Of course, friendship is a two-way street. To have good friends, you need to 28______ a good friend too. You should be honest, caring, and willing to help when your friends need you. Making and keeping friends takes time and effort, but it’s 29______ it. Good friends make our lives richer and happier.

Making friends seems harder than ever before, especially for teenagers who spend much of their time online. However, making real friends is important for our happiness and mental health. Here are some tips on how to make friends. First, be yourself. Don’t try to be someone you’re not just to impress others. True friends will like you for who you are. If you pretend to be different, you’ll always worry about being found out, and that’s not a good basis for friendship. Second, show interest in others. When you meet someone new, ask them questions about themselves. People like to talk about their interests and experiences. Listen carefully to what they say, and remember important details about them. This shows that you care. Third, join clubs or activities that interest you. This is a great way to meet people who share your interests. Whether it’s a sports team, a book club, or a volunteer group, you’ll automatically have something in common with the people there. Fourth, be a good listener. When your friends talk to you, give them your full attention. Don’t just wait for your turn to speak. Show that you understand how they feel by nodding and making appropriate comments. Fifth, be reliable. If you make plans with friends, keep them. If you promise to do something, do it. People trust friends who are dependable. Finally, be patient. Good friendships take time to develop. Don’t expect to become best friends with someone immediately. Start with small steps – say hello, have a short conversation, then maybe sit together at lunch. Making friends might seem challenging, but it’s a skill that can be learned. By following these tips and being open to new people, you can build meaningful friendships that will enrich your life. （ ）31、Why does the author think making friends is especially hard for teenagers today?

While it offers new opportunities for connection, it also presents challenges for developing deep, meaningful friendships. On the positive side, the Internet makes it easier to meet people who share our interests. Through social media, online games, and forums, we can connect with people from all over the world who like the same things we do. For people who are shy or have difficulty making friends in person, online friendships can be a comfortable starting point. The Internet also helps us stay in touch with friends who move away. With video calls and messaging apps, distance is no longer a barrier to maintaining friendships. However, there are drawbacks to online friendships. First, it’s easier for people to pretend to be someone they’re not online. Without face-to-face interaction, we might not know if someone is being honest about who they are. Second, online communication often lacks the depth of in-person conversations. We might share surface-level information but not have the deep, meaningful talks that build strong friendships. Third, spending too much time online can actually make us feel more lonely. Virtual connections cannot fully replace the warmth of a real hug or the shared laughter of being together in person. The healthiest approach is to balance online and offline friendships. Use the Internet to meet people and stay connected, but make sure to spend quality time with friends in person too. Plan activities together, have meals, or simply hang out. These face-to-face interactions help build trust and create shared memories that form the foundation of lasting friendships. Remember, whether online or offline, the principles of good friendship remain the same: honesty, trust, care, and mutual respect. A true friend is someone who supports you, understands you, and is there for you through good times and bad. （ ）36、According to the passage, what is one advantage of making friends online? A. Online friends are always honest. B. It’s easier to meet people with similar interests. C. Online friendships are deeper than offline ones. D. You don’t need to spend time with online friends. （ ）37、Why might online friendships be a good starting point for shy people? A. Because they can pretend to be someone else. B. Because online communication is more comfortable for them. C. Because they don’t need to talk to people face-to-face. D. Because online friends are usually kinder. （ ）38、What is one disadvantage of online friendships mentioned in the passage? A. Online friends live too far away. B. It’s difficult to find people with similar interests online. C. Making online friends takes too much time. D. Online communication often lacks depth. （ ）39、What does the author suggest for maintaining healthy friendships? A. Only make friends online. B. Only make friends offline. C. Never use the Internet to make friends. D. Balance online and offline friendships. （ ）40、What is the main idea of the passage? A. The Internet is bad for making friends. B. Online friendships are better than offline friendships. C. The Internet has both advantages and disadvantages for friendships. D. Making friends was easier before the Internet. C School trips are an important part of education. They provide students with opportunities to learn outside the classroom, experience new things, and develop social skills. However, planning a successful school trip requires careful preparation. First, teachers need to choose an appropriate destination. The place should be educational and related to what students are learning in class. For example, if students are studying history, a museum or historical site would be a good choice. If they’re learning about science, a science center or zoo might be more suitable. The destination should also be safe and age-appropriate. Second, permission is essential. Teachers must get permission from the school administration and parents. Parents need to sign permission forms and provide emergency contact information. Teachers should also inform parents about the trip details, including the destination, schedule, transportation, and what students need to bring. Third, safety is the top priority. There should be enough adult supervisors for the number of students. Teachers need to establish clear rules and make sure students understand them. Students should know what to do in case of an emergency. It’s also important to have a first aid kit and know the location of the nearest hospital. Fourth, preparation is key. Before the trip, teachers should prepare students by discussing what they will see and do. Students can research the destination and prepare questions. This makes the trip more meaningful and educational. During the trip, teachers should encourage students to observe carefully, ask questions, and take notes. After the trip, follow-up activities are important. Students can write reports, give presentations, or create projects based on what they learned. A well-planned school trip can be a memorable learning experience. It can make lessons come alive and inspire students’ interest in learning. While planning a school trip takes time and effort, the educational benefits make it worthwhile. （ ）41、What is the main purpose of school trips according to the passage? A. To give teachers a break from teaching. B. To provide opportunities for learning outside the classroom. C. To allow students to have fun without studying. D. To visit interesting places for entertainment. （ ）42、What should teachers consider when choosing a destination for a school trip? A. Whether it is the most expensive place. B. Whether it is related to what students are learning. C. Whether it is far away from the school. D. Whether it has good food options. （ ）43、Why is it important to get permission from parents for a school trip? A. Because parents need to pay for the trip. B. Because parents might want to join the trip. C. Because parents need to provide emergency contact information. D. Because parents decide what students will learn on the trip. （ ）44、What should teachers do before the trip to make it more meaningful? A. Prepare students by discussing what they will see and do. B. Tell students they don’t need to study for tests during the trip. C. Promise students they will have a lot of free time. D. Allow students to choose any destination they want. （ ）45、What is the passage mainly about? A. The history of school trips. B. How to plan a successful school trip. C.
