[单项选择]The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.
RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that
A. a new regulation for all airlines
B. the defects of electronic devices
C. a possible cause of aircraft crashes
D. effective safety measures for air flight

[单项选择] Nonverbal (非语言的) communication has to do with gestures, movements and closeness of two people when they are talking. The scientists say that those gestures, movements and so on have meaning which words do not carry. For example, the body distance between two speakers can be important. North Americans often complain that South Americans are unfriendly because they tend to stand close to the North American when speaking, while the South American often considers the North American to be "cold" or "distant" because he keeps a greater distance between himself and the person he is speaking to . The "eye contact" provides another example of what we are calling nonverbal communication. Scientists have observed that there is more eye contact between people who like each other than there is between people who don’’t like each other. The length of time that the person whom you are speaking to looks at your eyes indicates the amount of interest he has in the things you are talking about.
A. Less eye contact suggests distance in relation.
B. The longer one looks at you, the more interest he has in you.
C. There is more eye contact between people who like each other.
D. Shorter eye contact shows more interest in what one is talking about.
