閱讀下列短文，從各題所給的A、B、C、D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。

　　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 past 15 years, pilots have reported well over 100 incidents that have been caused by electromagnetic interference (電磁干擾). The source of this interference remains unconfirmed, but increasingly, experts point the blame at portable computers, radios 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 - oft and landing. Some experts have gone further, calling for a total ban during the flight. Currently, rules on using these devices are left up to individual airlines. And although some airlines forbid passengers from using such equipment during take - off and landing, most are reluctant (勉強(qiáng)) to enforce a total ban, given that many passengers want to work during the flight.

　　The difficulty is predicating how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices give out radiation, which affects wave lengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.

　　The fact that aircraft may be vulnerable (易受損的) to interference raises the risk that terrorists may use a radio system in order to damage navigation equipment.

1．The passage above mainly talks about ________.

[　　]

A．a(chǎn) new rule for airlines

B．the disadvantages of electronic devices

C．a(chǎn) possible cause of aircraft crashes

D．safety measures for air flight

2．Over 100 air- crash incidents have taken place during the past fifteen years, the reason is probably that ________.

[　　]

A．they may have been caused by the damage to the radio system

B．they may have taken place during the take - off and landing

C．they were proved to have been caused by the passengers' portable computers

D．the pilots are not expert at electromagnetics

3．Few airlines wish to entirely forbid passengers to use electric devices because ________.

[　　]

A．they don't believe in such a danger as radio interference

B．the harmful effect of them is yet to be proved

C．most passengers don't want to take a plane which doesn't allow the use of radios or cassette players

D．they will take other safety measures

4．It can be inferred from the passage that the writer ________.

[　　]

A．is in favor of forbidding passenger's use of electronic devices completely

B．hasn't formed his own opinion on the problem

C．regards it as unreasonable to forbid using electric devices during the flight completely

D．strongly believe that air incidents are caused by electromagnetic interference

閱讀理解

　　Three years ago, five parrots were set free in a wild place of Arizona, thousands of miles from the Channel IsIands in Jersey sher they had been looked after by zookeepers．No evolutionary strategies informed them how to behave in this new Iandscape of mountainous pine forest unoccupied by their king for 50 years．To the researchers’ surprise, they failed to make comtact with a group of wild parrots imported from Mexico and set free at the same time．Within 24 hours the reintroducing ended in failure, and the poor birds were back in cages, on their way to the safety of the Arizona reintroduction programme．

　　Ever since then, the programme has enjoyed great success, mainly because the birds now being set free are Mexican birds illegally caught in the wild, confiscated(沒收)on arrival north of the border, and raised by their parents in the safety of the programme．The experience shows how little we know about the behaviour and psychology(心理)of parrots, as Peter Bennett, a bird researcher, points out：“Reintroducing species of high intelligence like parrots is a lot more difficult．People like parrots, always treating them as nothing more than pers or valuable ‘collectables’．”

　　Now that manty species of parrot are in immediate danger of dying out, biologists are working together to study the natural history and the behaviour of this family of birds．Last year was an important turning point：conservationists founded the World Parrot Trust, based at Hayle in Cornwall, to support research into both wild and caged birds．

　　Research on parrots is vital for two reasons．Forst, as the Arizona programme showed, when reintroducing parrots to the wild, we need to be aware of what the birds must know if they are to survive in their natural home．We also need to learn more about the needs oft parrots keot as pets, particularly as the Trust’s campaign does not attempt to discourage the practice, but rather urges people who buy parrots as pets to choose birds raised by humans．
