五月的阳光下，一簇簇鲜花婀娜多姿。微风拂过，蔷薇醉人的香味芬芳扑鼻，茉莉花幽幽的香味沁人心脾。花香充斥着鼻腔，让人仿佛来到了仙境之中。我不禁疑惑起来，花儿为什么会如此之香呢，难道是从花蕊里散发出来的香味吗？原来呀，花的香气不是从花蕊散发出来的，而是从花瓣里散发出来的。因为花瓣里有一种油细胞，它会不断分泌出带有香味的芳香油，因为芳香油很容易挥发，所以当花开的时候，芳香油就会随着水分一起散发出来，这就是我们闻到的花香。看到答案之后，我恍然大悟，不禁感叹自然界的神奇。

妈妈喜欢百合花清新淡雅的气味，爸爸喜欢兰花浓郁香艳的气味，为什么不同的花会有不同的香味呢？是由于各种花卉所含的芳香油不同，所以散发出的香味也不一样，有的浓郁，有的淡雅。一般来说，天气晴朗的时候香味会更加浓郁。怪不得每次雨后天晴，出门的时候总是能闻到一股淡淡的幽香。我不禁遐想起来：我长大后，要发明一台可以发出花朵香味的仪器，那我们无论是在雨天，阴天或者晴天，无时无刻，随时随地都可以闻到花朵那美妙的香味，如果教室里装上了它，我听课都会认真三分；如果旅行时总能闻到它，我心情都会愉悦许多。也许你想问，这不就是香水吗？香水呀，主要用于个人，而我这种机器可以直接让整个环境都有淡淡的香味，而且香味像空调一样可大可小，可开可关。

但令人难过的是，现在的空气污染太严重了，相比于鲜花的香味，我们出去闻到的大多都是汽车的尾气，工厂的废气。让我们一起绿色出行、低碳生活，做新时代环保好少年吧！让空气更清新，让花香满世界！
