C、However, Hughie...and making Alan Trevor felt that nobody helped him stop from lauging.
D、However, Hughie...and making Alan Trevor felt that Hughie was hopeless by way laughing.
【正确答案】：A
【题目解析】：此句关键在于理解helpless with laughter的含义。形容词helpless有“无助的，无自理能力的”之意，helpless with sth.—般指“无法抑制某事，情不自禁干某事”，因此可知，helpless with laughter是指“无法抑制地笑，情不自禁地笑”，也即选项A中的unable to stop laughing。答案为A。
