问题补充：

the hotel for the Ice and Snow Festival in Harbin has already begun.

A. Booked

B. Booking

C. Bought

D. Buying

答案：

A. Booked

(答案→)B. Booking

C. Bought

D. Buying

解析：考查动名词做主语及动词的词义辨析。Book预定；buy购买；本题中的动名词短语Booking the hotel for the Ice and Snow Festival in Harbin在句中做主语，表示经常性习惯性的行为。句意：哈尔滨冰雪节的宾馆预定已经开始了。要注意过去分词是不能在句中做主语的。Buy的语义和句子不搭配。故B正确。
