3. 霧霾臉

smog face

請看例句：

Well-known Chinese otolaryngological expert and professor Zhang Quan'an alleged that "smog will make people look uglier year by year". Smog face sounds exaggerated but has theoretical support.
國內知名耳鼻喉專家張全安教授稱，霧霾會讓人逐年變丑。"霧霾臉"的說法聽起來夸張，但確有理論依據。

當兒童因霧霾中的有害顆粒物刺激鼻腔而患上鼻炎時(get coryza due to an irritation of the nose caused by harmful particles in smog)，其鼻腔堵塞，必須用嘴呼吸(their nose gets blocked and they have to use their mouths to breathe)。這不利于兒童的面部發育，會造成其上唇短厚翹起，牙齒排列不整齊(develop a short thick upturned upperlip and an irregular row of teeth)。

不僅如此，由于兒童的大腦仍在發育中，呼吸困難會導致其大腦發育遲緩(experience retarded development)。目前來說，兒童抵御霧霾天危害的最安全有效的途徑(the safest and most effective way)還是戴口罩(wear masks)。
