Most Americans have at least one credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad. And they also make many banking services available. For many of us the "cashless society’.’ is already here.

Most people would agree that it would be wonderful if humans could regenerate limbs. These who have lost their arms or legs would be complete again. The day is still far off when this might happen. But in the last 10 years, doctors have reported regeneration in smaller parts of the body, most often fingers.

Their experiments show that nerves, cell chemistry and the natural electric currents in the body all seem to have a part in this process.
The body of every animal contains general purpose cells that change into whatever kind of cells the body needs. Animals such as the lizard or salamander (蝾螈) use these cells
A. humans can never regenerate limbs.
B. humans might be able to regenerate limbs in the future.
C. human limbs may be regenerated on some animals first.
