Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals (信号) from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called“galvanometer”. The galvanometer is placed on a leaf of the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them-perhaps by pulling off leaves or by pulling it out of its pot?-then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects(昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.

Mrs Matthews lived in a small town where there was one jeweller's shop. It also took in watch repairs, although it had to send them off to London for the work to be done, as there was not enough business to keep an expert watch repairer occupied.
When Mrs Matthews's old father died, she inherited his gold watch, which had belonged to his father and grandfather before him. It was big and heavy and worth a lot of money, but it was broken, so Mrs Matthews took it to be repaired.
The man in the jeweller's shop was very interested to see such an unusual watch, and when he had examined its insides, he said he could certainly have it repaired for her. “It'll last a long time once that's been done.”he said. He wrote out a ticket and gave it to Mrs Matthews saying. “Please bring this when you come to pick up the watch. But it might take a bit of time, because it isn't a modem watch.”
But Mrs Matthews had a lot of things to think about after her father died. She had to arrange to deal with the various affairs after her father's death.
The result was that she completely forgot about the watch that she had taken in for repair, and about the ticket for it, which she had put away in a drawer to keep it safe.
Then, while she was looking through some old drawers one day, she found the ticket for the watch repair.
She thought back, suddenly she remembered.“My father's gold watch! Didn't I pick it up? When did I take it in?”She looked at the ticket.
“How old's this ticket?” she said to herself. It was five years old.
Mrs Matthews had heard that shops could sell things that people had left with them if they didn't pick them up and pay for them before a certain time. “But the watch might still be there,”she thought.“I'll go and see if I can get it back. It might have been sold, but I hope not.”
She took the ticket to the jeweller's and the shopkeeper looked at it and then went to look for the watch without saying a word.
“That's good,”Mrs Matthews thought.“He didn't seem to mind about the date.”
The man came back after a few minutes and said,“It won't be ready until Friday.”

As far back as 700 B.C., man had talked about children being cared for by wolves. Romulus and Remus, the old story twin founders of Rome, were said to have been cared for by wolves.
