Have you ever imagined what the world will be like in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundreds of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have relative higher per-head food consumption. Mean-while, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more severe. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly. |

A. things will get even worse B. things will be a little better C. it will be necessary for them to improve their housing D. it will be impossible to obtain enough necessities of life |

A. to 90 percent as estimated B. to any country in the world that needs it C. to developing countries D. to those countries that already have high per-head consumption |

Tom was one of the brightest boys in the year, with supportive parents. But when he was 15 he suddenly stopped trying. He left school at 16 with only two scores for secondary school subjects. One of the reasons that made it cool for him not to care was the power of his peer (同龄人) group. The lack of right male (男性的) role models in many of their lives - at home and particularly in the school environment (环境)-means that their peers are the only people they have to judge themselves against. They don't see men succeeding in society so it doesn't occur to them that they could make something of themselves. Without male teachers as a role model, the effect of peer actions and street culture (文化) is all- powerful. Boys want to be part of a club. However, schools can provide the environment for change, and provide the right role models for them. Teachers need to be trained to stop that but not in front of a child's peers. You have to do it one to one, because that is when you see the real child. It's pointless sending a child home if he or she has done wrong. They see it as a welcome day off to watch television or play computer games. Instead, schools should have a special unit where a child who has done wrong goes for the day and gets advice about his problems - somewhere he can work away from his peers and go home after the other children. |
1. Why did Tom give up studying? |
A. He disliked his teachers. B. His parents no longer supported him. C. It's cool for boys of his age not to care about studies. D. There were too many subjects in his secondary school. |
2. What seems to have a bad effect on students like Tom? |
A. Peer groups. B. A special unit. C. The student judges. D. The home environment. |
3. What should schools do to help the problem schoolboys? |
A. Wait for their change patiently. B. Train leaders of their peer groups. C. Stop the development of street culture. D. Give them lessons in a separate area. |
4. A teacher's work is most effective with a schoolboy when he _____. |
A. is with the boy alone B. teaches the boy a lesson C. sends the boy home as punishment D. works together with another teacher |
What is it about a dog&39;s gaze that makes it so charming? A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.
The cuddle chemical has another, more scientific name: oxytocin. Oxytocin is a substance in the blood that encourages bonding. Levels of oxytocin increase, for example, when a mother feeds her newborn baby. According to Nagasawa&39;s study, the same is true when we look deeply into the eyes of a dog.
The results of this study can tell us a lot about the history of the bond between humans and dogs. It all started somewhere tens of thousands of years ago. Scientists believe that wolves used to follow humans who were hunting large animals. The wolves would eat the food left behind by the humans.
Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.
Over time, the wolves that interacted with the humans began to change. They became more loyal to their human partners. The wolves and humans started to depend on each other and bond with each other. These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie^ evolved to better survive in their environment.
This process depended a great deal on the bond humans formed with them. And according to Nagasawa&39;s study, this bond was formed with the help of oxytocin, the cuddle chemical.
11. What do we know about oxytocin?
A.It regulates blood flow
B.It promotes bonding
C.It is in the human gene
D.It is good for health
When we look deeply into a dog's eyes, the levels of our oxytocin ____.A.reduce over time
B.go either up or down
C.are on the rise
D.remain unchanged
At the beginning wolves followed humans to ____.A.eat the food left by humans
B.guard against large animals
C.take humans for food
D.hunt large animals together
Over time some wolves turned into dogs ____.A.due to their loyalty
B.due to the changing environment
C.for better survival
D.for better cooperation
What does Nagasawa9s study aim to do?A.Explore the role of human-wolf partnership
B.Show the characteristics of the cuddle chemical
C.Explain the bond between humans and dogs
D.Understand the evolution of species
