Ⅲ. 物理课程 Amy 在周五参与了一节特别的物理课，老师带领学生来到了学校操场旁的滑梯。老师要告诉学生什么呢？
跨学科 物理 Slides are simple but always fun. All you need to do is to climb up to the top and slide down. But do you know that there is science behind this simple playground equipment?
Isaac Newton said what goes up must come down. He was talking about gravity. Gravity is an invisible force(看不见的力量) that pulls everything down. Slides work because of gravity， that is not all.
You climb up the slide sit down. You are ready to go. Are you sliding down? No， not yet. Things stay still unless something makes them move. It is Newton's first law， you have to give yourself a push to start the journey down.
Now you are sliding down. Do you feel you are slowing down a bit? When two things rub(摩擦) against each other， they cause friction. It is a force that works against the movement.
Without friction， you would slide down faster and faster to the bottom of the slide. It would be dangerous， that might be more fun.
At the bottom of the slide， you come to a full stop. Your feet touch the ground and add extra friction. Newton's first law also says moving objects keep moving unless something stops them. So if you do not use your feet， you will fly off the slide and hurt yourself.
新考法 创新设问 Which of the following can be put into NO. 1 and NO. 2?
1. A. How fun a slide is! B. How does science make a slide work?
C. How dangerous to slide down with a toy! D. How fast can you slide down a slide?
2. A. jumping down from the high B. walking on the ground
C. flying in the sky D. throwing a basketball into a basket
3. Which of the following is the RIGHT order of the missing linking words(缺失的连词)?
A. ①but ②and ③although ④so B. ①and ②but ③although ④so
C. ①but ②and ③so ④although D. ①and ②but ③so ④although
4. What can you infer from the passage?
A. Only heavy things that are lifted can come down from the slide.
B. Things stay still until something makes them move.
C. The water on the leaves will fall because of the friction.
D. According to Newton's first law， a moving bike can't stop until the rider presses the brake.
Questions: 1. 新考法 开放性试题 What fun class did you or will you have at your school? What's it about?
2. What can you learn from it?

答案
1.B 2.B 3.C 4.D
【语篇解读】本文主要介绍了滑梯工作的科学原理。
1. B 解析:主旨大意题。根据“But do you know that there is science behind this simple playground equipment?”及表格的内容可知,本文是介绍滑梯工作的科学原理。故选B。
2. B 解析:推理判断题。根据“When two things rub against each other, they cause friction.”可知,当两种东西相互摩擦时,它们会产生摩擦力。B选项“在地面上行走”可以产生摩擦。故选B。
3. C 解析:细节理解题。根据“Slides work because of gravity, ... that is not all.”可知,滑梯因为重力而工作,但不是全部,前后句是转折关系,用but;根据“You climb up the slide ... sit down.”可知,climb up the slide与sit down两者是并列关系,用and;根据“It is Newton's first law, ... you have to give yourself a push to start the journey down.”可知,这是牛顿的第一定律,所以你必须给自己一个推力,才能开始这段旅程。后句是前句的结果,用so连接;根据“It would be dangerous, ... that might be more fun.”可知,这很危险,虽然可能更有趣,前后句是让步关系,用although引导让步状语从句。因此正确的顺序是①but ②and ③so ④although。故选C。
4. D 解析:推理判断题。根据“Newton's first law also says moving objects keep moving unless something stops them.”可知,牛顿第一定律还说,运动中的物体会继续运动,除非有外力使其停止,因此可推知在骑行者按下刹车之前,移动的自行车无法停止。故选D。
Questions:
1. I will have a music class. The students will sing and act together in a music play.(答案不唯一,言之有理即可)
2. I can learn how to work with others to make the play better.(答案不唯一,言之有理即可)

【分析】
本题是跨学科英语阅读理解题，包含4道选择题和2道开放性试题。解题思路如下：
1. 第1题为主旨大意题，需通读全文，抓住核心内容——介绍滑梯背后的科学原理，排除偏离主旨的选项；
2. 第2题为推理判断题，结合摩擦力的定义（两物体相互摩擦产生），分析选项中符合摩擦现象的内容；
3. 第3题为连词填空题，分析每个空格前后句子的逻辑关系（转折、并列、因果、让步），匹配对应连词；
4. 第4题为推理判断题，结合牛顿第一定律的内容，逐一验证选项合理性；
5. 开放性试题结合自身经历作答，言之有理即可。
【解析】
1. 第1题：根据文中“But do you know that there is science behind this simple playground equipment?”及表格内容，可知本文主旨是介绍滑梯工作的科学原理，A、C、D均偏离主旨，故选B。
2. 第2题：摩擦力产生于两物体相互摩擦，A、C、D无摩擦现象，B（在地面行走）是脚与地面摩擦，符合要求，故选B。
3. 第3题：①处前后为转折关系，用but；②处前后为并列动作，用and；③处前后为因果关系，用so；④处前后为让步关系，用although，对应选项C，故选C。
4. 第4题：A选项错误（重力对所有物体适用）；B选项是原文直接表述，非推断；D选项符合牛顿第一定律（运动物体除非受外力停止，故骑行者按刹车前自行车不会停），故选D。
开放性试题答案示例：
1. I will have a music class. The students will sing and act together in a music play.（答案不唯一，言之有理即可）
