本文介绍了自己动手制作彩虹的实验步骤。
1. B 细节理解题。由What you'll need下面的“A sunny day.”可知选B。
2. C 推理判断题。由Rainbows form in the sky when sunlight is refracted as it passes through raindrops可知，彩虹的形成需要具备的两个条件是阳光与水滴。
3. B 推理判断题。本文介绍制作彩虹的过程，由全文及常识可知，彩虹的形成涉及光的折射现象，这是物理知识，因此最有可能在物理课做这个实验。

【分析】
本题是围绕自制彩虹实验的应用文阅读理解题，需通过查找细节、结合原理推理来解答。第1题找实验所需天气，第2题提炼自然彩虹形成条件，第3题判断适合的课程。
【解析】
1. 细节理解题：根据材料“What you'll need”部分提到的“A sunny day”，可知做实验最好在晴天，故选B。
2. 推理判断题：根据材料中“Rainbows form in the sky when sunlight is refracted as it passes through raindrops”，可知自然彩虹形成需要阳光和水滴，故选C。
3. 推理判断题：实验涉及光的折射原理，属于物理知识，因此最可能在物理课上进行，故选B。

There are thousands of kinds of animals in the Amazon rainforest, each coloured differently. Most rainforest animals use their colours for survival.
Some animals use colours to protect themselves from their predators(猎食者). An example is the green iguana. Young iguanas are bright green and hide among the bright green leaves of the trees where they live. As they grow older, their colour becomes duller. Old iguanas live higher in the trees, where the colours all around are less bright.
Other animals are predators and use colours to hide from their prey. The boa constrictor(蟒蛇) is a good example. Some boas are grey or brown, and their colours help them hide in the trees. The emerald tree boa is green and white, so it can easily hide in the leaves. A boa hides in a tree and waits for a bird to fly by. When one does, the boa grabs the bird from the air and then squeezes it to death before eating it.
Colourful frogs can be orange, red, or green. Their bright colours let everybody know where they are. The bright colour warns other animals that the frog is poisonous, so they stay away. These tiny frogs are very poisonous! One frog has enough poison to kill 100 people.
The colours of the rainforest are beautiful to us, but to the animals they are very important. They help the animals survive.
()1. What colour is the adult iguana?
A. Bright green.
B. Dull green.
C. Grey or brown.
D. Green and white.
()2. What does the underlined word "prey" mean?
A. 祈祷
B. 捕食者
C. 猎物
D. 朋友
()3. 新考法·篇章结构 How is the passage organized? (P = Paragraph)

()4. In which part of a magazine may we read this text?
A. History.
B. Culture.
C. Arts.
D. Nature.

亚马孙雨林中有成千上万种动物，每种动物都有不同的颜色。大多数雨林动物利用它们的颜色来生存。一些动物利用颜色来保护自己免受捕食者的伤害，比如鬣鳞蜥。其他动物则利用颜色来隐藏自己，比如蟒蛇和翡翠蟒。还有一些动物如青蛙，它们的鲜艳颜色是为了警告其他动物它们有毒，让其他动物远离它们。雨林动物的颜色对它们的生存非常重要。
1. B 细节理解题。根据第二段中“Young iguanas are bright green and hide among the bright green leaves of the trees where they live. As they grow older, their colour becomes duller.”可知，成年鬣鳞蜥是暗绿色的。
2. C 词义猜测题。根据第三段中“A boa hides in a tree and waits for a bird to fly by. When one does, the boa grabs the bird from the air and then squeezes it to death before eating it.”可知，蟒蛇隐藏自身的颜色来捕鸟，再结合画线词所在句可知，prey意为“猎物”。
3. A 篇章结构题。通读全文可知，第一段说的是亚马孙雨林中有成千上万种动物，每种动物都有不同的颜色。大多数雨林动物利用它们的颜色来生存。第二、三、四段分别用具体的动物来举例说明颜色的作用。第五段总述雨林动物的颜色对它们的生存非常重要。故本文采用的是总分总的结构。
4. D 推理判断题。通读全文可知，本文说的是亚马孙雨林中有成千上万种动物，每种动物都有不同的颜色。所以我们可以在杂志的自然部分阅读此内容。

【分析】
这是一篇关于亚马孙雨林动物颜色作用的说明文阅读理解，共4道题，分别考查细节理解、词义猜测、篇章结构、推理判断。解题思路：1. 细节理解题：根据题干关键词定位原文对应段落，精准查找答案；2. 词义猜测题：结合上下文语境，分析画线词所在句的逻辑关系，推断词义；3. 篇章结构题：通读全文，梳理段落间的逻辑关系，判断文章结构；4. 推理判断题：根据文章主旨内容，判断文章所属的杂志板块。
【解析】
1. 细节理解题：根据题干关键词“adult iguana”定位到第二段，文中提到“Young iguanas are bright green... As they grow older, their colour becomes duller.”，可知成年鬣鳞蜥颜色更暗，对应选项B。
2. 词义猜测题：第三段讲蟒蛇是捕食者，会隐藏自己捕捉鸟类，画线词所在句“hide from their prey”意为隐藏自己避开猎物，结合语境可知prey是“猎物”，选C。
3. 篇章结构题：第一段总述雨林动物用颜色生存，第二、三、四段分别举例说明不同动物颜色的作用，第五段总结颜色对动物生存的重要性，是总分总结构，对应选项A。
4. 推理判断题：文章围绕亚马孙雨林动物的颜色展开，属于自然类内容，应在杂志的自然部分，选D。
