(2014·德州模拟)Some animals will defend their territory by fighting with those who try to invade it.Fighting，however，is not often the best choice，since it uses up a large amount of energy，and can result in injury or even death.Most animals rely on various threats，either through sounds or smells.The songs of birds，the drumming of woodpeckers and the loud calls of monkeys are all warnings that carry for long distances，advertising to possible invaders that someone else’s territory is being approached.Many animals rely on smells to mark their territories or leaving droppings around the territories.Other animals will be warned off the territory without ever meeting with the territory’s defender.
Sometimes，these warnings may be ignored，and an invader may move accidentally into a neighboring territory，or two animals may meet near the border of their nearby territories.When the two animals meet，they will generally threaten each other with visual (视觉的) displays.These displays will often exaggerate an animal’s size by putting up feathers or fur，or will show off the animal’s weapons.The animals may go through all the behavior of fighting without ever actually touching each other.The displays are generally performed best near the center of an animal’s territory，where it is more likely to attack an invader and where retreating becomes more of a choice.
Actual fighting usually only happens in overcrowded conditions，when resources are not enough.Serious injury can result，and old or sick animals may die，leading to a more balanced population size.Under most natural conditions，territoriality is an effective way of maintaining a healthy population.The study of social behaviors such as territoriality in animals may also help us to understand human society.

Birds use vocalizations to attract mates, defend territories, and recognize fellow members of their species. But while we know a lot about how variations in vocalizations play out between populations of songbirds, it's far less clear how this variation affects birds such as penguins in which calls are inherited (遗传). A new study from The Auk: Ornithological Advances examines differences in the calls of Little Penguins from four colonies in Australia-night-time birds for whom vocalizations are more important than visual signals-and finds that differences in habitat, rather than geographic isolation (隔离) or other factors, seem to be the key driver of variation in the sounds these birds use to communicate.
Diane Colombelli-Negrel and Rachel Smale of Australia's Flinders University recorded calls from four Little Penguin populations across a small area of South Australia, one of which had previously been shown to have slight genetic differences from the other three, and used playback experiments to test penguins ability to distinguish between calls from different colonies.They found that agonistic calls, which are used in pair displays and aggressive situations, varied among the four populations, and that the calls' characteristics appeared to depend on small-scale differences in the habitat where the penguins lived. However, birds did not discriminate between calls originating from different colonies, which suggests that agonistic calls don't seem to play a role in isolating the two different genetic groups.
Penguins living in open habitats produced lower-frequency calls than those living in habitats with thicker vegetation-the opposite of the trend typically observed in songbirds. The authors think that agonistic calls may be subject to different selective pressures because they're used in close encounters with other birds rather than to communicate across distances, and could also be influenced by variation in the noise level of wind and surf.
“I was excited to find that in seabirds, as most of our knowledge in this area comes from studies on songbirds," says Colombelli-Negrel. "This new research suggests that many factors influence call variation in birds, which also depends on the function of the calls. This study highlights that many questions remain and that studies need to investigate more than one factor in conjunction with the function of the calls to fully understand call variation in seabirds.”
“This work tells an interesting story of vocal diversification in Little Penguins, and gives insight into how individual and micro-scale variation effects behavior," according to Stony Brook University's Heather Lynch, an expert on penguin calls who was not involved in the study. "Non-vocal-learning birds are relatively understudied in terms of vocalizations, and it is great to see penguin vocalizations being studied in such a way."
1.What does the new study find?
A.Penguins are born with their calls.
B.Penguins communicate by various calls.
C.Penguins' calls are influenced by their habitat.
D.Penguins' calls can help isolate genetic groups.
2.What are the findings based on?

B.The data collected from penguins across Australia.
C.Controlled experiments on penguins and songbirds.
D.Similarities between the calls of penguins and songbirds.
3.From the passage we can learn that .
A.open-space songbirds tend to lower their calls
B.environmental noises may affect penguins' calls
C.birds use agonistic calls in distant communication
D.songbirds' agonistic calls vary little between species
4.We can infer from Colombelli-Negrel's words that researchers .
A.will keep track of penguins to preserve them
B.have investigated a lot in penguins' calls before
C.will have a broader look at differences in penguins' calls
D.have determined the function of various calls in penguins

Chimps will cooperate in certain ways, like gathering in war parties to protect their territory. But beyond the minimum requirements as social beings, they have little instinct to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their children, who are able from a young age to gather their own food.
In the laboratory, chimps don’t naturally share food either. If a chimp is put in a cage where he can pull in one plate of food for himself or, with no great effort, a plate that also provides food for a neighbor to the next cage, he will pull at random ---he just doesn’t care whether his neighbor gets fed or not. Chimps are truly selfish.
Human children, on the other hand are extremely cooperative. From the earliest ages, they decide to help others, to share information and to participate in achieving common goals. The psychologist Michael Tomasello has studied this cooperativeness in a series of experiments with very young children. He finds that if babies aged 18 months see an unrelated adult with hands full trying to open a door, almost all will immediately try to help.
There are several reasons to believe that the urges to help, inform and share are not taught .but naturally possessed in young children. One is that these instincts appear at a very young age before most parents have started to train children to behave socially. Another is that the helping behaviors are not improved if the children are rewarded. A third reason is that social intelligence develops in children before their general cognitive (认知的) skills, at least when compared with chimps. In tests conducted by Tomasello, the children did no better than the chimps on the physical world tests, but were considerably better at understanding the social world.
The core of what children’s minds have and chimps’ don’t is what Tomasello calls shared intentionality. Part of this ability is that they can infer what others know or are thinking. But beyond that, even very young children want to be part of a shared purpose. They actively seek to be part of a “we”, a group that intends to work toward a shared goal.
1.What can we learn from the experiment with chimps?
A. Chimps like to take in their neighbors’ food.
B. Chimps tend to provide food for their children.
C. Chimps seldom care about others’ interests.

2.Michael Tomasello’s tests on young children indicate that they_________.
A. know the world better than chimps
B. know how to offer help to adults
C. have the instinct to help others
D. trust adults with their hands full
3.The passage is mainly about _________.
