Now let’s look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved(进化) through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way.
In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species.
For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled.
Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities.

| B．resist natural offers |
| C．go to the moon |

Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils(灾祸).
People’s choice of colors is also influenced by their bodies’ reactions(反应) toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomach aches.
Red can cause a person’s blood pressure to rise and increase people’s appetites(食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person’s eye.
Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

Having put down your pens at the end of the college entrance exam, you have ended 12 years of hard study. Forget your studies for a while. It’s time to enjoy yourselves!
There are many ways to celebrate this special month of graduation. You can have photos taken with your classmates and teachers, or dine out together and exchange gifts.
High school students in Western countries such as the United States and Canada usually have a prom to mark their graduation. It’s to mark the time kids turn into young men and women. After the prom, teenagers either go to college or find a job. It means they are no longer as dependent on their parents as they were before.
At the prom, boys usually dress in dinner jackets and bow ties, though many different types of formal clothes are worn. Traditionally, girls give boys matching boutonnieres ( 佩带在扣眼上的花). Girls traditionally wear formal dresses, or dress to shock or be noticed, in shiny or brightly colored materials.
Common prom activities include dining, dancing, the crowning (加冠) of a prom king and queen, and just talking to friends. In some cases, high school students collect funds for their class prom through the four years of their high school.
High schools in or near large cities may rent ballrooms at expensive hotels or, to be unusual, in a pleasure cruise boat.
But often costs are cut by simply using the school gym. Students make a lot of effort to decorate the gym to make the event special. The music played at the prom will be the most popular kinds, like rock and hip-hop.
The students elect the Prom Queen. She is partnered with a Prom King who is elected similarly. These are great honors that the pair take very seriously. The two dance with each other to celebrate their election.
