Natural Resources
Through the changes in the ways of making a living in a family over several generations, the cartoon aims at sounding a warning against man’s wasteful use of natural resources and emphasizing the urgent need to preserve these resources.Ever since man appeared on the earth, man’s survival has been heavily dependent on nature. Almost everything we use in our everyday life comes from nature, ranging from the food we eat, the water we drink, to the wood which is turned into furniture. With the development of technology and population growth, the amount and range of materials used has increased at an alarming rate.However, natural resources are not inexhaustible. Some reserves are already on the brink of exhaustion and there is no hope of replacing them. The widespread water shortage is an example in point. If man continued to squander natural resources with no thought for the future, the whole world would be in a mess.

House and Home
“House” and “home” are two words that have similar meanings.“House” and “home” both refer to places where people live. However, there is a difference between them. “Home” is often referred to as the place that we live in with our families. Sadly, in our society, people can hardly distinguish a home from a house because they often see no difference between them. This confusion can be traced back to the indifference between family members. Therefore, we can say that love is an important factor in a home. A home is a shelter, not only for our bodies but also for our minds. Whenever we are depressed, we can go home for comfort. Everyone in the family will do his best to take care of each other and share their happiness as well as sorrow. Without love, a home is merely a house where loneliness is all that can be found. And a house can never be a home unless there is love.
Useful words and expressions:1. refer to 提到2. distinguish区别，辨别3. confusion 混乱，混淆4. trace back 追溯到5. indifference 不关心6. depressed 沮丧的
Automobiles
It is impossible to say that any one man invented the automobile. Many individuals living and working in different countries and at different times contributed to its development. Many of the discoveries that went into the creation of the automobile were small in themselves. But together they were important. Here are two examples.“Carriage is running at a speed of 8 to 9 miles an hour.” It was almost unheard of in those days. According to automobile historians, this was the first practical use of mechanical power to move a vehicle. After its first run, the machine reportedly burned up while the inventor and his friends were celebrating its success at a pub.Henry Ford is considered the father of modern automobiles mass production. His famous Model-T car, because of its low price, made it possible to produce cars on a large scale and his efforts made it accessible to ordinary people.
Useful words and expressions:
1. reportedly 据传说，据传闻2. mass production大规模生产3. on a large scale 大规模地4. accessible 易接近的，可到达的accessible to 与……接近
The Influence of Life
In the early times when human beings hunted and gathered food, they were not in control of their environment. They could only interact with their surroundings as the other lower animals did.When they learned to make fire, however, they became capable of altering their environment. To provide themselves with fuel, they cut down trees. They also burned clearings in forests to increase the growth of grass and to provide a greater grazing area for the wild animals that human beings fed upon. This development led to farming and the domestication of animals. Fire provided the means for cooking plants which had previously been inedible. Only when the process of meeting the basic need for food reached a certain level was it possible for humans to follow other pursuits such as setting up families, forming societies and founding cities.
Useful words and Expressions:
1. interact with 与……组合2. clearing 空旷地3. grazing 放牧，牧草4. domestication 驯养，驯服5. previously 先前，以前6. inedible 不能吃的，不适于食用的7. pursuit 追击8. set up 设立
Population Growth
It is well-known that there has been a drastic increase in world population. But it is probably les well-known that the extinction rate of wildlife species is experiencing a parallel trend.Take the United States for instance. In 1990, U.S. population reached an unprecedented level of 250 million, which is approximately 250 times of that of 1800. On the other hand, wildlife species are disappearing from the country at an alarming rate. By 1990, about 70 wildlife species would never be seen in U.S. We are fully justified in declaring that the explosive population growth has had an adverse effect on the survival of wildlife species and will be a constant threat to the wildlife resources if no immediate actions are taken.Nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world. It has been demolishing the environment we are living in.
Useful words and expressions:1. drastic 激烈的2. parallel 平行的3. trend 倾向4. unprecedented 空前的5. magnitude 大小，数量6. alter 改变7. demolish 毁坏
Don’t give upIf we would ever accomplish anything in life, let us not forget that we must persevere. If we would learn our lessons in school, we must be diligent and not give up whenever we come to anything difficult. We shall find many of our lessons very hard, but let us consider that the harder they are the better they will do to us if we will preserve and learn them thoroughly.But there are some among us who are ready to give up when they come to a hard example in mathematics, and say, “I can’t do this.” They never will if they feel so. “I can’t” never does anything worthwhile, but “I’ll try” accomplishes wonders.Let us remember that we shall meet with difficulties all through life. They are in the pathway of everyone. If we will only try and keep trying, we shall be sure to conquer and overcome very difficulty we meet.
Our Concern
The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Only in the present century has one species of man acquired significant power to alter the nature of his world.The rapidity of change follows the pace of man rather than the pace of nature. Radiation is now the unnatural creation of man’s tampering with the atom. The chemicals are the creations of man’s inventive mind, having no counterparts in nature.We have put poisonous and biologically potent chemicals into the hands of persons largely ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. We have allowed these chemicals to be used with little or no advance investigation of their effect. Future generations are unlikely to forgive our lack of concern.

Sleep
Why is it so difficult to fall asleep when you are overtired? There is no one answer that applies to every individual. It is possible to feel “tired” physically and still be unable to fall asleep, because while your body may be exhausted, you do not feel sleepy. It is not so easy to simply “turn off”.Lack of sleep complicates matters even more. Experts say adults need at least seven to eight hours of sleep a night to function properly. When you get less sleep than that on consecutive three nights, you begin to accrue four “sleep debt”. As sleep debt increases your body experiences a stress response. Now a vicious cycle has been created: You experience the feeling of being more and more tired, but your body is increasingly stimulated. “Power sleeping” for more hours on weekends is only a temporary solution. There is no substitute for getting a good night’s sleep on a regular basis.
Useful Words and Expressions:1. overtire 使过度疲劳2. apply to 将……应用于3. consecutive 连续的，连贯的4. accrue 自然增加，产生5. vicious恶的vicious cycle 恶性循环6. stimulate 刺激，激励7. substitute for 代替……，替换……
Apology Helps
It is never easy to admit you are in the wrong. Being human, we all need to know the art of apologizing. Look back with honesty and think how often you have judged roughly, you said unkind things, and pushed yourself ahead at the expense of a friend. Then count the occasions when you indicated clearly and truly that you were so sorry. A bit frightening, isn’t it? It is frightening, isn’t it? It is frightening because some deep wisdom in us knows that when even a small wrong has been committed, some mysterious moral feeling is disturbed; and it stays out of balance until fault is acknowledged and regret expressed.A heartfelt apology can not only heal a damaged relationship but also make it stronger. If you can think of someone who deserves an apology from you, someone you have wronged, or judged too roughly, or just neglected, do something about it right now.
Useful Words and Expressions:1. push ahead 捉紧进行2. at the expense of 在损害……的情况下3. mysterious神秘的4. moral 道德的5. disturbed 扰乱的6. stay out of 不参与……，置身于……之外7. heartfelt 衷心的，真心真意的8. roughly粗糙地，概略地
How High Can You Jump?Fleas trainers have observed a strange habit of fleas while training them.Fleas are trained by putting them in a cardboard box with a top on it. The fleas will jump up and hit the top of the cardboard box over and over and over again. As you watch them jump and hit the lid, something very interesting becomes obvious. The fleas continue to jump, but they are no longer jumping high enough to hit the top.When you take off the lid, the fleas continue to jump, but they will not jump out of the box. They will not jump out because they cannot jump out. Why? The reason is simple. They have conditioned themselves to jump just so high. Once they have conditioned themselves to jump just so high. Once they have conditioned themselves to jump just so high, that is all they can do!Many times, people do the same thing. They restrict themselves and never reach their potential. Just like the fleas, they fail to jump higher, thinking they are doing al they can do.
Useful Words and Expressions:1. cardboard 纸板2. lid 盖子3. conditioned 有条件的，习惯于……的4. restrict 限制，约束be restricted within narrow limits 限于狭窄的范围内be restricted in one’s movements 行动受限制
