Put on your 3D glasses and the dinosaur jumps off the screen. There are butterflies in the air around you. How does all this happen?
When you are seeing a 3D movie, it seems that a red ball is jumping right at you. But the ball isn't truly leaving the screen. What's happening is that your brain and eyes work together to work out the ball's size, colour, shape, and movement. It looks real, but it's an illusion! Our eyes are like video cameras. They notice every detail of the red ball and how it moves. At the same time, our brain guesses what will happen next. That's why we think the red ball is flying straight at us!
But how do 3D movies make objects seem like they're floating in the air? They trick our brain! Here's how 3D movies work: the movie is filmed using cameras with two lenses which are placed close to each other, just like our eyes. When the movie plays, these two pictures are shown on the screen at the same time. One picture is a bit different from the other because each camera lens catches its own view. The two pictures overlap, and that's why they look unclear without 3D glasses.
This is where the special glasses come in. A 3D movie uses two kinds of light: horizontal(side-to-side) light and vertical(up-and-down) light. The glasses help your left eye see the picture using horizontal light and your right eye see the picture using vertical light. Then, your brain mixes the two pictures into one. That's when the magic of 3D happens!
With 3D glasses, the experience can be fun and exciting. Just remember that it's all a clever trick to make you feel like you're right there in the movie!

本文主要介绍了 3D 电影的工作原理和观看体验。
1. C 行文方式题。根据第一段“Put on your 3D glasses and the dinosaur jumps off the screen. There are butterflies in the air around you. How does all this happen?”可知，作者通过描述一个场景开始这篇文章。
2. A 词义猜测题。根据第二段中“It looks real, but it’s an illusion!”并结合选项可知，此处 illusion 意为“不真实的东西”。
3. D 信息排序题。根据第三段中“the movie is filmed ... When the movie plays, these two pictures are shown on the screen at the same time ... The two pictures overlap, and that’s why they look unclear without 3D glasses.”和第四段中“The glasses help your left eye ... Then, your brain mixes the two pictures into one.”可知，本题答案为④②③⑤①。
4. D 推理判断题。文章主要介绍了 3D 电影是如何制作出来的。由此可知，本文最有可能出现在杂志的“电影的秘密”部分。

【分析】
1. 第1题（行文方式题）：需定位文章开头，分析开头的写作手法，判断作者如何开启文章。
2. 第2题（词义猜测题）：结合划线词所在句的上下文语境，通过转折逻辑推断词义。
3. 第3题（信息排序题）：梳理3D电影从拍摄到呈现的步骤，对应原文的先后顺序排列选项。
4. 第4题（推理判断题）：根据文章核心内容，推断其最可能出现在杂志的哪个板块。
【解析】
1. 第1题：根据文章第一段“Put on your 3D glasses and the dinosaur jumps off the screen. There are butterflies in the air around you.”可知，作者通过描述戴3D眼镜时的场景开启文章，故选C。
2. 第2题：划线词所在句为“It looks real, but it's an illusion!”，由转折连词but可知，illusion与“真实”语义相反，意为“不真实的东西”，故选A。
3. 第3题：根据原文步骤：①电影用双镜头相机拍摄（④）；②播放时两张图同时显示（②）；③两张图重叠导致无眼镜时模糊（③）；④3D眼镜处理水平和垂直光（⑤）；⑤大脑混合两张图成一张（①），正确顺序为④②③⑤①，故选D。
4. 第4题：文章主要介绍3D电影的工作原理，属于电影的秘密相关内容，故最可能出现在杂志的“Secrets of Movies”板块，故选D。
