Passage ThreeEducation is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them; our purpose is to prepare them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life. It is not enough just to choose the first system of education one finds, or to continue with one's old system of education without examining it to see whether it is in fact suitable or not.In many modern countries, it has for some time been fashionable to think that by free education for all—whether rich or poor, clever or stupid—one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider "low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor. We can live without education, but we will die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability, and secondly, we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.44. Education is______.

As holidays go, Thanksgiving is in some ways the most philosophical. Today we try not to take for granted the things we almost always take for granted. We try, if only in that brief pause before the eating begins, to see through the well-worn patterns of our lives to what lies behind them. In other words, we try to understand how very rich we are, whether we feel very rich or not. Today is one of the few times most Americans consciously set desire aside, if only because desire is incompatible with the gratitude—not to mention the abundance-that Thanksgiving summons.

Practice 3　　We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.　　But, in a larger sense, we can not dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us, the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us.. that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion; that we here highly resolve that these dead shall not have died in vain; that this nation, under god, shall have a new birth of freedom; and that government of the people, by the people, and for the people, shall not perish from the earth.（The Gettysburg Address—Abraham Lincoln）
