You stand in a garden. A low noise reaches your ears. You see a small insect flying near your head. You turn to look, and it flies out of sight. There it is again! You move slowly. You can see yellow and black stripes on it.
Is it a bee? It lands on a flower, and you take a closer look.
Bees fold their wings onto their backs when they stop flying. But this insect's wings reach out like a fly's. That's because it is a fly—a flower fly.
Many flower flies look like bees. This helps keep them safe from animals that may want to eat them. Insects with yellow and black stripes usually have stings(刺). Insect eaters, such as some birds and frogs, need to get stung only once to know that stripes mean trouble. Flower flies can't sting, but insect eaters see the stripes and leave the flies alone.
Flower flies spend most of their time looking for food. Like bees, flower flies eat pollen(花粉)and nectar(花蜜). This makes them easy to find in a garden full of flowers. They are helpful garden insects just like bees. Adult flower flies move pollen from one flower to another, which helps some flowers grow into fruit.
Flower flies can stay in one place while flying. Most insects move forward when they fly. But flower flies can twist their wings, much like hummingbirds do. Twisting keeps them in one place, so they can remain over flowers, leaves, or even you!

答案：[语篇解读] 本文介绍了花蝇的外观特征、行为习性以及它们与蜜蜂的相似之处和不同之处,旨在向读者介绍有关花蝇的知识。
1. A 推理判断题。通读全文可知,本文主要介绍了花蝇的相关知识,应该在杂志的“自然”部分看到此文章。
2. D
3. C 词义猜测题。根据“Insect eaters, such as some birds and frogs, need to get stung only once to know that stripes mean trouble. Flower flies can't sting, but insect eaters see the stripes and leave the flies alone.”可知,带有黄色和黑色条纹的昆虫通常有刺,花蝇身上有黄黑条纹,虽然它身上没有刺,但是一些以昆虫为食的动物看到花蝇身上的条纹就会远离花蝇,故画线部分意为“远离花蝇”。
4. B 推理判断题。根据“Is it a bee? It lands on a flower, and you take a closer look.”及“Many flower flies look like bees.”可知,花蝇的外观和生活习性与蜜蜂有些相似,所以人们有时会把花蝇误认为蜜蜂。

解析：
【分析】本题为自然主题的英语阅读理解题，解题思路为：1. 通读全文，把握文章介绍花蝇的核心内容；2. 针对不同题型（推理判断、细节理解、词义猜测），定位原文对应信息，结合语境分析选项；3. 逐一验证选项，选出符合原文的答案。
【解析】1. 第1题：推理判断题。文章主要介绍花蝇的外观、习性等自然生物知识，这类内容通常出现在杂志的“自然”板块，故选A。
2. 第2题：细节理解题。根据原文“Bees fold their wings onto their backs when they stop flying. But this insect's wings reach out like a fly's.”可知，蜜蜂和花蝇停止飞行时翅膀的状态不同，故选D。
3. 第3题：词义猜测题。前文提到有黄黑条纹的昆虫通常有刺，天敌被蛰后会避开这类条纹昆虫；花蝇无刺但有黄黑条纹，天敌看到条纹就会远离它，故“leave the flies alone”意为“远离花蝇”，选C。
4. 第4题：推理判断题。文中提到“Is it a bee? It lands on a flower, and you take a closer look.”以及“Many flower flies look like bees.”，说明花蝇与蜜蜂外观相似，人们有时会将花蝇误认为蜜蜂，故选B。
【答案】1.A 2.D 3.C 4.B
【知识点】英语阅读理解、词义猜测、推理判断
【点评】本文是跨学科的自然生态类说明文，围绕花蝇的相关知识展开，题型涵盖细节理解、词义猜测、推理判断，考查学生的语篇理解和信息提取能力，难度适中，适合中等水平学生练习。
