Question

5．May 19th is China's Tourism Day，and when it comes，tourists are allowedto visit （visit） some tourist attractions for free．

Answer 1

分析 5月19日是中國的旅游日，當那一天到來，游客們被允許免費參觀一些旅游景點．

解答 答案：to visit．結合句意are allowed這里是一般現在時的被動語態，表示允許某人做某事用allow sb to do sth，被動語態為sb be allowed to do sth，后加動詞不定式，所給單詞visit是動詞參觀，故答案是to visit．
