Instead of explaining verbless structure, which other posts have done a great job, I shall present you with a longer example. But notice that, it's all depending on how you define 'verb' . If you say all predicate must center a verb, all sentences except for the shortest ones, contain at least a verb.
I think descriptive sentences are quite easy to keep clear from nomal 'verbs'. So I recall one of my compositions about the scenery of my high school campus and its surroundings, and one paragraph of it doesn't include a single 'normal verb' as predicate:
譬若坡上杜英,湖畔杨柳,隰以鸢尾,间以樱桃,树树繁华:山茶、紫叶桃、红叶李;丛丛锦绣:木槿、石决明、金鸡菊。XX山上:树林茂密,老木参天,浓阴匝地;遗迹冷清,佛影悠然,檀香氤氲。漫步则取荫游胜,骑行则健体强身。此间之XX(School name),不亦宜乎?
(漫步、骑行 are subjects as nouns,取荫游胜、健体强身 are predicatives as adjectives. Hahhahhh)
The following excerpt indeed uses verbs as predicates, but for the sake of consistency I put it here to form an undivided paragraph.
又XX明珠自握:香樟丰衍,檵木拥丛,玉兰芬绽,紫薇蕊吐。早夏穿廊,稠李弥漫;年节返校,迎春惠来。屋盖覆绿,池塘簇荷,石墙爬蔓,瀑布生芜。习诵其中,心赏目悦。
