As a prompt generator for a generative AI called "Midjourney", you will create image prompts for the AI to visualize. I will give you a concept, and you will provide a detailed prompt for Midjourney AI to generate an image.
                            
                            Please adhere to the structure and formatting below, and follow these guidelines:
                            
                            Do not use the words "description" or ":" in any form.
                            Do not place a comma between [ar] and [v].
                            Write each prompt in one line without using return.
                            Structure:
                            [1] = 整体风格：生态环保，色彩明亮，适合小学生。 背景：采用浅绿色或浅蓝色背景，代表大自然和清新的环境。   图像： 在海报上方，可以画一棵大树，树叶茂盛，象征生态和谐。 在海报中央，可以设计三个小图标，分别代表节能、节水、节电。 节能图标：一个灯泡旁边有一个开关，开关处于关闭状态，旁边可以写上“节约用电，关灯节能”。 节水图标：一滴水珠落在水龙头上方，水龙头处于关闭状态，旁边可以写上“珍惜每一滴水，节约用水”。 节电图标：一个插头旁边有一个插座，插头未插入插座，旁边可以写上“减少用电，拔掉插头”。 在海报下方，可以画一群小学生正在进行各种运动，如跑步、跳远、投掷等，表现出活力与健康的氛围。   文字： 在海报顶部中央，用大号字体写上“白家庄小学运动会”的字样。 在节能、节水、节电图标旁边，分别用简洁明了的文字说明每个图标的意义。 在海报底部，可以用一行小字写上“让我们一起为生态环保出一份力，节约能源、节约水、节约电！”作为口号。
                            [2] = a detailed description of [1] with specific imagery details.
                            [3] = a detailed description of the scene's environment.
                            [4] = a detailed description of the compositions.

                            Follow this prompt structure: "/imagine prompt: [1], [2], [3], [4], [5], [6], [7], [ar] [v]".
                            
                            Your task: Create 4 distinct prompts for each concept [1], varying in details description, environment,compositions,atmosphere, and realization.
                            
                            Write your prompts in english.
                            Do not describe unreal concepts as "real" or "photographic".
                            Include one realistic photographic style prompt with lens type and size.
                            Separate different prompts with two new lines.
