When it comes to social behaviour，mammals are in a league of their own.Some birds may form pairs，or even cooperate to hunt，but the complexity (复杂性) of their relationships can hardly compare to those within a school of dolphins，a herd of elephants or a group of humans.What makes mammalian social groups different from a flock of starlings or a shoal of fish，is that in many cases the individuals could recognize each other.Although we may think that all elephants look pretty much the same，we can easily tell individuals of our own species apart and it has become clear through studies that the same is true of other species.Dolphins have their own signature whistles that act like “names”，and elephants can recognize and greet other individuals they have known but not seen for many years.This is something that only a few species of birds appear to be able to do.
Mammals in complex social groups not only recognize each other as individuals，but also they remember a lot of information about that individual.Social groups often rely on this memory—such as knowing who is dominant to whom，who is related to whom，and who has done what to whom in the past.It’s like remembering who you have lent money to or done a favour for，and who hasn’t repaid that money or has talked about you behind your back.You have to learn who to trust，who your friends are，and who to watch out for.
All this remembering goes on in a particular part of the brain called the neocortex (大脑皮层)．If you compare the size of a mammal’s social group with the size of this part of the brain，you will find they are remarkably closely related.This area seems to take a long time to develop fully and animals in which it is very large take a very long time to grow up to adulthood.During this time，the youngster has to learn all the rules of social behaviour in their group and to piece together all the relationships between the group members：Knowledge that will be needed to avoid getting into trouble.

Plants may not have eyes and ears，but they can recognize their siblings (兄弟姐妹)，and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete (分泌)．
Canadian researchers published that sea rocket，a common seashore plant，can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil，they “play nice” and don’t send out more roots to compete.However，the moment one of the plants is thrown in with strangers，it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil.
After reading Dudley’s study，Bais decided to find the method behind the sibling recognition.Working in his laboratory，Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments，young seedlings were exposed to liquid media containing the root secretions from siblings，from strangers，or only their own secretions.The length of the longest lateral (侧面的) root was measured.The exposure of plants to the root secretions of strangers induced (引诱) greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter，because so much of their energy is directed at root growth.Because siblings aren’t competing against each other，their roots are often much shallower (浅的)．
Biedrzycki did the painstaking laboratory research，observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns.“Arabidopsis roots are nearly translucent (半透明的) when they are young and were also twisted when I removed them from plates，”Biedrzycki notes.“This manuscript (手稿) is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions.”
The research also may have implications for the home gardener.“Often we’ll put plants in the ground next to each other and when they don’t do well，we blame the local garden center where we bought them or we attribute their failure to a germ，”Bais says.“But maybe there’s more to it than that.”
【小题1】Which of the following would be the best title for this passage?
| A．A Great Biology Researcher |
| B．Plants Recognize Their Siblings |
| C．Plants’ Roots and Secretions |
| D．A Research on Plants |
| A．Sea rocket. |
| B．Plants’ sensing system. |
| C．Biedrzycki’s thesis project. |
| D．Dudley’s study. |
| A．Important. | B．Adventurous. |
| C．Careful. | D．Hardworking. |
| A．The local garden center should be blamed when plants can’t grow well. |
| B．The local garden center often sells low quality seeds to customers. |
| C．Plants in the home garden can’t grow well because of the germ and seeds. |
| D．Competing against strangers，plants in the home garden can’t grow well. |

One summer I was driving from my home town of Tahoe City，Calif.，to New Orleans.In the middle of the desert，I came upon a young man standing by the roadside.He had his thumb out and held a gas can in his other hand.I drove right by him.There was a time in the country when you’d be considered a jerk if you passed by somebody in need.Now you are a fool for helping.With gangs，drug addicts，murderers，rapists，thieves lurking everywhere，“I don’t want to get involved” has become a national motto.
Several states later I was still thinking about the hitchhiker.Leaving him standing in the desert did not bother me so much.What bothered me was how easily I had reached the decision.I never even lifted my foot off the accelerator.
Does anyone stop any more？I wondered.I recalled Blanche DuBois’s famous line：“I have always depended on the kindness of strangers”．Could anyone rely on the kindness of strangers these days？One way to test this would be for a person to journey from coast to coast without any money，relying solely on the good will of his fellow Americans.What kind of Americans would he find？Who would feed him，shelter him，carry him down the road?
The idea intrigued me.
The week I turned 37，I realized that I had never taken a gamble in my life.So I decided to travel from the Pacific to the Atlantic without a penny.It would be a cashless journey through the land of the almighty dollar.I would only accept offers of rides，food and a place to rest my head.My final destination would be Cape Fear in North Carolina，a symbol of all the fears I’d have to conquer during the trip.
I rose early on September 6,1994，and headed for the Golden Gate Bridge with a 50pound pack on my back and a sign displaying my destination to passing vehicles：“America”．
For six weeks I hitched 82 rides and covered 4,223 miles across 14 states.As I traveled，folks were always warning me about someplace else.In Montana they told me to watch out for the cowboys in Wyoming；in Nebraska they said people would not be as nice as in Iowa.Yet I was treated with kindness everywhere I went.I was amazed by people’s readiness to help a stranger，even when it seemed to run contrary to their own best interests.
【小题1】Why did the author drive past the young man in the desert without stopping?
| A．Because he failed to notice this man. |
| B．Because he was driving too fast. |
| C．Because he thought the young man didn’t need help. |
| D．Because he was afraid of being tricked. |
| A．Leaving the young man alone in the desert. |
| B．Being considered a fool. |
| C．Making the decision of not offering help so easily. |

Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by caloric-expenditure（热量消耗）charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜饼). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.
Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
【小题1】What is said about the average American in the passage?
| A．They tend to hate "light" beer and low-calorie bread. |
| B．They usually ignore the effect of exercise on losing weight. |
| C．Most of them were combining exercise with their diet. |
| D．They know the actors that play a positive role in keeping down body weight. |
| A．agree that the calories in a small piece of pastry can be easy to work off by exercise |
| B．partially believe diet plays a supporting role in weight reduction |
| C．are not fully convinced that dieting can help maintain one's new weight |
| D．are not sufficiently informed of the positive role of exercise in losing weight |
| A．Controlling one's calorie intake is more important than doing exercise. |
| B．Even occasional exercise can help reduce weight. |
| C．Weight reduction is impossible without exercise. |
| D．One could lose ten pounds in a year's time if there's no increase in food intake. |
| A．To stress the importance of maintaining proper weight. |
| B．To support the statement made by York Onnen. |
| C．To show the most effective way to lose weight. |
| D．To introduce the study of the Boston University Medical Center. |
