2017职称英语考试模全真拟试题理工类B级第二套
The new voice card also identifies itself by-its ID squawk、but it will not do this until it has verified the legitimate user's spoken password.Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy.
The challenge for Beepcard has been to develop voice—recognition and audio circuitry that can be powered by a mini battery embedded in a credit card.To maximize battery life，the electronics are only switched on when the card is being used.Pressing a button on the card's surface prompts it to utter “Say your password” in female voice.If the voice-recognition software proves that the password is authentic， it sends its ID squawk which the server then identifies，allowing the transaction to proceed.

Agitated Sunspot Cause Trouble
If the lights in your house keep flickering， blame frequent sunspots.
A sunspot is actually charged particles flying at the speed of 3 million kilometers an hour out of the surface of the sun to form sun storms.
__1__.
The earth， which is directly energized by the sun， is influenced by sun storms in a number of ways.
__2__. Wireless short-wave communication， which depends on the wave's reflection against this layer of atmosphere， is likely to be jammed. It is said that mobile phone communication may be affected too.
__3__. According to a research conducted by the Russian scientists from 1957 to 1960， the frequency of earthquakes can be linked to the movement of the sunspots.
Though little research has been carried out about how exactly the sunspot will negatively harm the health of the people， a paper published by a North Korea observatory says that sun storms may cause an increase in the incidence of heart disease and skin disease. __4__.
Besides， the nervous system is also affected， and traffic accidents are more frequent when sunspots are active.
It is hard to say when the sunspots are most violent during their active year， but generally one active period is believed to last possibly eight days. Not long ago there were two violent sun storms breaking out， which seriously affected mobile phone communication， etc. in many parts of the world. __5__.
