单选题 CHICAGO(AP) On Jan. 1, an order went into effect requiring that every checked bag at more than 400 of the nation"s commercial airports be screened for bombs and weapons.
Sunday was expected to be the heaviest travel day since Jan. 1. Yet spot checks on Sunday at several of the nation"s airports showed no major delays caused by the new security measures.
At the international terminal for Northwest Airlines at John F. Kennedy International Airport in New York, passengers waited up to 30 minutes longer than usual. Their bags were sent through giant screening machines and workers tore open taped boxes and searched through their contents before closing them up again.
Most travelers simply accepted stricter screening developed since the terrorist(恐怖分子的) attacks on Sept. 11, 2001, before which only 5 percent of the roughly 2 million bags checked each day were screened for bombs.
The U.S. government has put an additional 23,000 people into airports to carry out the new order.
Sonny Salgatar, a 23-year-old college student flying home to San Diego from Chicago, was told by an airport officer after the first pass that one of his bags was "hot", meaning there was something he couldn"t identify and he wanted to open the bag for an inspection.
The "hot" item turned out to be Salgatar"s clothing iron.
"Listen, anything they want to do for security is OK for me," Salgatar said.

单选题 The new measure was adopted to guard against ______.

【正确答案】 A

【答案解析】[解析] 文章开头就提到了这次行动命令的目的“On Jan. 1, an order went into effect requiring that every checked bag at more than 400 of the nation"s commercial airports be screened for bombs and weapons.”是为了检查包裹中的炸弹和武器。

单选题 The word "hot" (Para. 6) most probably means ______.

单选题 Which of the following is TRUE according to the passage?

【正确答案】 B

【答案解析】[解析] 本题可用排除法。A项“执行新的检查，引起了很多的航班延误”，而文中第二段内容“Yet spot checks on Sunday at several of the nation"s airports showed no major delays caused by the new security measures.”与此相反。C项“乘客们抱怨在机场耽搁的时间太长”，而文中第四段第一句“Most travelers simply accepted stricter screening developed since the terrorist attacks on Sept. 11, 2001”，可见大多数的乘客是接受这种检查而引起的时间上的耽搁，没有抱怨，所以不是答案。D项“更多更严格的检查措施将会推行”，文中没有涉及。所以选B项“大多数乘客认为新的检查措施是必要的”。

单选题 What was the attitude of Sonny Salgatar towards the security measure taken?

【正确答案】 B

【答案解析】[解析] 文中最后举例的这个大学生，因为携带电熨斗，要求被拆包检查，但是最后他表明态度“Listen, anything they want to do for security is OK for me”，可见他十分理解这种检查，没有反对。
