今天这篇教程汇总谷歌官方6大模板、加码真机实测、失败反转与彩蛋福利，复制即可用，保你5分钟产出第一张惊艳四座神图。
官方反复强调：Nano Banana 擅长读故事，而不是堆关键字。
我刚才第一次丢给 Banana 关键词，结果猫画的好假；但改用叙事句后，画出来的壁纸效果好多了，这波反差狠狠调动了我们团队的肾上腺素。
堆关键词：猫, 赛博朋克, 4K, 酷
读故事：在紫霾缭绕的赛博朋克小巷，一只装着机械义肢的黑猫蹲在反光路牌上，霓虹招牌映出蓝紫色光晕。

再送：五条大神级提示词秘技
一、拆步骤：先背景→再主体→最后光线；模型思路更清晰。
二、语义负词：与其说 “no cars”，不如说 “an empty cobblestone street at dawn”。
三、镜头术语：macro shot、low‑angle、tilt‑shift，掌控视角。
四、细节名词：visible linen weave 让布料不会糊。
五、对话迭代：Keep everything else, turn sunset warmer，精准修图。
