男士说他只有随身携带的行李(carry-on luggage)和一台手提电脑(laptop)，所以没有需要托运的行李(D)。选项(A)、选项(B)、选项(C)均不正确。

【正确答案】 C

【答案解析】女士说“The flight will begin boarding at 7:00...(七点开始登机)”，所以选项(C)正确。选项(A)中的three指登机口的号码。选项(B)中的five和选项(D)中的eight均末在对话中出现。

【正确答案】 D

【答案解析】选项(D)是唯一不正确的陈述，因为对话中未提及飞机是否延误(delayed)。从The flight will begin boarding...from gate E-3可以判断选项(B)为正确的陈述，从Traveling business class...可以判断选项(C)为正确的陈述，从on an overnight flight like this可以判断选项(A)为正确的陈述。
