Plants have family values, too; it seems, with new research suggesting they can recognize close relatives in order to work together.
An ability to tell family from strangers is well known in animals, allowing them to cooperate and share resources, but plants may possess similar social skills, scientists believe.
Susan Dudley and Amanda File of McMaster University in Ontario, Canada, report they have demonstrated for the first time that plants can recognize their kin.
This suggests that plants, though lacking recognition and memory, are capable of complex social interactions.
“Plants have this kind of hidden but complicated social life，” Dudley said.
The study found plants from the same species of beach-dwelling wildflower grew aggressively alongside unrelated neighbors but were less competitive when they shared soil with their families.
Sea rocket, a North American species, showed stronger and healthier root growth when planted in pots with strangers than when raised with relatives from the same maternal(母系的) family, the study found.
This is an example of kin selection, a behavior common in animals in which closely related individuals take a group approach to succeeding in their environment, the researchers said.
Kin selection also applies to competition, because if family members compete less with each other, the group will do better overall. “Everywhere you look, plants are growing right up next to other plants，” Dudley said，“ Usually it’s a case of each plant for itself. But sometimes those plants are related, and there are benefits to not wasting resources on being competitive, and there is not really a cost to not being competitive as long as your neighbor is also not being competitive.”
Learning and memory appear to be important for kin recognition in animals, but this isn’t an option for plants, she noted.
Some researchers speculate(猜测) that plants communicate through their roots, identifying themselves using tiny chemical signatures specific to each plant’s family.

In the first place, television is not only a convenient source of entertainment, but also a .comparatively cheap one. With a TV set in the family people don't have to pay for expensive seats at the theatre, the cinema, or the opera. All they have to do is to push a button or turn a knob, and they can see plays, films, operas and shows of every kin& Some people, however, think that this is where the danger lies. The television viewers need to do nothing. He does not even have to use his legs if he has a remote control. He makes no choice and exercises no judgment. He is completely passive and has everything presented to him without any effort on his part.

Television, it is often said, ______ of current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one's sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger: The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it, so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and that they have actually begun to talk to each other again. It makes one think, doesn't it?

There are many other arguments for and against television. We must realize that television in itself is neither good nor bad. It is the uses to which it is put that determines its value to society.
