单选题 What is true about North Sun Airlines?
A. It offers worldwide flights
B. It is based in the United States
C. It holds a sale every summer
D. It sells cheap round-trip tickets
【正确答案】 C
【答案解析】[解析] 通过第一段第1和2句中的annual和as usual可以知道，此活动为年度例行活动，在每年的夏天举行，故选C。
单选题 How much do the majority of one way sales fights probably cost?
A. Less than $44
B. Between $44 and $64
C. Around $100
D. More than $100
【正确答案】 C
【答案解析】[解析] 注意题干中的表达the majority of。此题没有对所有机票的价格进行提问，而是对全体中占大部分的机票价格进行了提问。从第三段中的价格表来看，10种机票中有6种机票的价格位于94美元到104美元之间。因此占全体机票大多数机票价格的平均值。
单选题 Which of the following is NOT a condition of the sale?
A. Flights must begin after May 21st
B. Flights must fall between May 1st and October 1st
C. Flights must end by October 1st
D. Flights must be paid for by May 1st
【正确答案】 B
【答案解析】[解析] 第三段指出活动只适用于5月21日到10月1日之间的航班，因此B不适用于此次活动。
单选题 The word "select" in paragraph 1, line 2 is closest in meaning to ______.
A. specific B. favorite C. excellent D. common
【正确答案】 A
【答案解析】[解析] select作为动词时，意为选择，这个大部分人都知道，但却不知它还可以做形容词表示“精选的”。原句指在众多地区中只局限于美国和加拿大等特定地区的活动，因此意为“特定的”。
