Recently I met a former student Jeanie, for lunch. She had been one of my sixth grade students. Before she had moved away, I had been asked to speak as someone who had been a motivator. I spoke telling the crowd gathered that she was a blessing and encouragement to me. She was a child that had come from a family with some problems. When we finally met, she told me that the thing that made me her favorite teacher was the speech I gave every year. I tell my students that when they wake each morning and come to school, they spend more time with me than they spend with their parents. They may be in the same house, but that does not mean that they spend time with them. I told them that my job was to teach them, comfort them, encourage them, and discipline them as needed. However, my most important job was to love them so that they could put away all other thoughts and prepare to learn. I have no losers in my class. They should therefore consider me their mom away from home.

Over lunch, Jeanie asked if she could have the honor of calling me “Mom”, because over the years I have always been a second mom to her.

Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help.

Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.

The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet.

The company also hopes to include other information on the chip, such as medical records, building security codes (密码) and passwords, making life even easier.

But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake (假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.

And if you wanted to get rid of your chip, you would need an operation to remove it.

1.The Verichip is ________.

A．the identity number B．the security code

C．a tiny microchip D．a radio reader

2.Which is true of the Verichip?

A．Your information on it will always be safe.

B．Medical records have already been included.

C．You can easily reach for your wallet using it.

D．An operation has to be performed to remove it.
