01 主题语篇 · Reading & Listening

Next semester, our school is going to introduce a new digital classroom program. Every student will get a tablet, and all textbooks will be replaced by e-books. Our headmaster announced the plan at the assembly yesterday. We are going to save a lot of paper, he said, and students will be able to study anywhere, anytime. Some parents are worried. They think children will spend too much time looking at screens. However, the teachers believe that the new devices will make learning more interactive. I am personally very excited. I am going to download a dictionary app tonight, and I will use it in my English class tomorrow. We will have a meeting next Friday to talk about the rules. I think we won't be allowed to play games during class. What do you think will happen?
下学期我们学校要推出一个新的数字课堂项目。每个学生都会拿到一台平板，所有课本将被电子书取代。校长昨天在集会上宣布了这个计划。我们将节省大量纸张，他说，学生将能随时随地学习。一些家长很担心。他们觉得孩子会花太多时间盯着屏幕。但老师们相信新设备会让学习更互动。我个人很兴奋。我今晚就要下载一个词典 App，明天英语课上就用。下周五我们要开个会讨论规则。我觉得课上不许玩游戏。你觉得会发生什么？

⚠ 易错陷阱

  • ① be going to 表计划： 已经计划好的事用 be going to（I am going to download），临时当场决定用 will（The phone is ringing — I will answer it.）。
  • ② will 后加原形： ✗ I will to download. → ✓ I will download（will 后不加 to）。
  • ③ there will be： ✗ There will have. → ✓ There will be a meeting next Friday.
  • 考试怎么考： 听力题问 What will the school do next semester? 抓 will + 动词。

M: Hey, are you going to the school fair this Saturday? W: I am not sure. I have a lot of homework this week. M: But the fair only happens once a year. There will be games, food, and a concert in the afternoon. W: Really? What time does it start? M: It starts at ten in the morning. The concert begins at three. W: How much is the ticket? M: It is five dollars for students, and eight for adults. Half price if you bring a food donation. W: That sounds like a good deal. I will ask my mom. Maybe I can finish my homework on Friday night. M: Great! Let me know. I will save you a ticket. W: Thanks. See you on Saturday, hopefully. M: See you!

13 小托福题型答题技巧（4 条）

📌 应试策略

  • 听力：听前先读选项，猜话题。听第二个人的回答，往往答案就在那里。
  • 语言形式：先找时间标志词（yesterday / every day / already），定时态再选变形。
  • 阅读：先读题，带着问题回原文定位。广告/通知类直接找数字和地点。
  • 时间管理：不会的题先跳过，做完有时间再回来。别在一道题上卡 5 分钟。
