嗅觉可以帮助我们感知周围环境中的气味。它的来源是我们的嗅觉器官——鼻子。当气味分子进入我们的鼻子时,它们会激活嗅觉神经元,然后这些信息会被传输到大脑中央的嗅觉皮层。
一些英文例句和中文翻译如下:
"Our sense of smell helps us detect danger, such as the smell of smoke from a fire." (我们的嗅觉帮助我们感知危险,例如火灾的烟味。)
"A person's sense of smell can also help them identify and enjoy different aromas, such as the scent of flowers or the aroma of freshly baked bread." (一个人的嗅觉还可以帮助他们辨别和享受不同的香味,例如花的香气或新鲜烘焙的面包的香味。)
"Our sense of smell is closely tied to our memory and emotions, which is why certain scents can bring back powerful memories and feepngs." (我们的嗅觉与记忆和情绪密切相关,这就是为什么某些气味会带回强烈的记忆和感受。)
