q1) …… 春天上海很漂亮 --- why not 《很漂亮了》 ? Answer) the expression still have a little inaccuracy，the correct expression is 上海春天很漂亮，the subject usually be used in the beginning of the sentence in Chinese, and 漂亮了 have a little implicit feelings like comparison, 你漂亮了means you’re more petty than before 2) ……可以去南边de海南游泳 --- which de: 《南边的》 or 《南边得》 ? Answer) 的 is used between two nouns 得 is used after verb and before adjective For example 蓝色的大海or 跑得快

了means something has happened, so u can't use 了 here. 的 is always used between adjectives and nouns.(example : colorful dream 彩色的梦） 得 is always used between verbs and Adjectives or Adverbs.（example : 干得漂亮！well-done 走得太快 walk too fast）
