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 industry,has recommended that all airlines ban 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 many passengers want to work during flights.
The difficulty is predicting how electromagnetic fields might affect an aircraft's computers.Experts know that portable devices emit radiation which affects those wavelengths 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 to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment.As worrying,though,is the passenger who can't hear the instructions to turn off his radio because the music's too loud.
3.Few airlines want to impose a total ban on their passengers using electronic devices because _____
A.they have other effective safety measures to fall back on
B.most passengers refuse to take a plane which bans the use of radio and cassette players
C.they don't believe there is such a danger as radio interference
D.the harmful effect of electromagnetic interference is yet to be proved
4.Why is it difficult to predict the possible effects of electromagnetic fields on an airplane's computers?
A.Because it remains a mystery what wavelengths are liable to be interfered with.
B.Because it is extremely dangerous to conduct such research on an airplane.
C.Because experts lack adequate equipment to do such research.
D.Because research scientists have not been able to produce the same effects in labs.

英语翻译
The threat of commoditization poses a real challenge for service providers.While the end-to-end principle
is often paraphrased as "dumb network,smart end-systems",the original paper makes a more subtle argument
about appropriate distribution of functionality among endpoints and intermediate systems.Functions may be
implemented in the network for performance reasons,and when they offer value to a wide range of applications
without inhibiting the correct operation of applications that do not need these functions.In this context,we
describe a prototype platform for experimentation with novel,useful functions "inside" the network.This
programmable platform allows service providers to innovate quickly and to deploy new functions within the
network when it makes sense.By implementing the platform as an overlay,service providers can assist those
applications that benefit from added functions such as caching and streaming support,without interfering with
the correct and efficient operationof other applications that do not need them.Service providers can also leverage
their detailed topological knowledge and ability to control network resources,features that would be difficult for
conventional overlays.Programmability of the platform enables features to be extended or composed with other
pieces of software,by either the service providers or third parties.
