  Mother Nature Shows Her Strength
  Tornadoes（龙卷风）and heavy thunderstorms moved across the Great Lakes and into
  Trumbull County on Saturday evening.The storms were dramatic and dangerous.
  George Snyder was driving the fire truck down Route 88 when he first noticed that a
  funnel（漏斗状的）cloud was behind him. " I stopped the truck and watched the funnel
  cloud.It was about 1 00 feet off the ground and I saw it go up and down for a while.It was
  moving toward Bradley Road and then suddenly it disappeared,"Snyder said.
  Snyder only saw one of the funnel clouds that passed through northeastern Ohio on
  Saturday.In Trumbull County,a tornado turned trees onto their sides.Some trees fell onto
  houses and cars.Other trees fell into telephone and electrical wires as they went down.
  Amanda Symcheck was having a party when the storm began."I knew something was
  wrong , " she said."I saw the sky go green and pink（粉红色）.Then it sounded like a
  train rushing toward the house.I started crying and told everyone to go to the basement for
  protection."
  The tornado caused a lot of damage to cars and houses in the area.It will take a long
  time and much money to repair everything.There was also serious water damage from the
  thunderstorms.The heavy rains and high wind caused the power to go out in many homes.
  The storms caused serious flooding in areas near the river. More than four inches of
  rain fell in parts of Trumbull County.The river was so high that the water ran into streets
  and houses.Many streets had to be closed to cars and trucks because of the high water.
  This made it difficult for fire trucks,police cars,and other rescue vehicles to help people
  who were in trouble.
  Many people who live near the river had to leave their own safety.
  Some people reported five feet of water in their homes.Local and state officials opened
  emergency shelters for the people who were evacuated(撤走).The Red Cross served meals to them.
  "This was a really intense storm,"said Snyder."People were afraid.Mother Nature can be fierce.We were lucky this time.No one was killed."
  Rescue vehicles had a hard time getting to people.

  B:Wrong

  Credit Card Only Works When Spoken To
  A credit card that will not work unless it hears its owner's voice could become an
  important weapon in the fight against fraud（欺骗）.
  The card requires users to give a spoken password that it recognizes using a built-in
  voice-recognition chip.The idea is to prevent thieves using a stolen card or fraudsters using
  someone else's credit card details to buy goods online.
  A model built by engineers at Beepcard in Santa Monica,California,represents the
  first attempt to pack a microphone,a loudspeaker,a battery and a voice-recognition chip
  into a standard-sized credit card.
  They are not quite there yet:the card is the length and width of an ordinary credit card,
  but it is still about three times as thick.The company now plans to make it thinner.
  The voice card is based on an earlier Beepcard technology designed to prevent fraud in
  online transactions.This earlier card has no microphone,but has a built-in loudspeaker
  that it uses to " squawk"（发出叫声）a voice ID signal via a computer's microphone to an
  online server.
  By verifying（证实）that the signal matches the card details,the server can establish
  that the user is not simply keying in a credit card number but actually has the card to hand.
  The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.
  This prevents fraudsters recording the beeps, noting the card details and then playing
  back the audible ID when they key in the details later.But this earlier technology cannot
  prevent fraudulent use of stolen cards.The new one can.
  The new voice card also identifies itself by its ID squawk,but it will not do this until it
  has verified the legitimate（合法的）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（嵌入的）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（真实的）,it sends its ID
  squawk which the server then identifies,allowing the transaction to proceed.
  The voice credit card is an important invention because
  A:it can be made cost-effectively.
  B:it can leave voice messages.
  C:it makes online shopping easy.
  D:it makes fraud difficult.
