(翻译)A smile costs nothing, but creates much. It enriches those who receive, without impoverishing those who give. It happens in a flash and the memory of it sometimes lasts forever. None are so rich that they can get along without it, and none so poor but are richer for its benefits. It creates happiness in the home, fosters goodwill in a business, and is the countersign of friends. It is rest to the weary, daylight to the discouraged and sunshine to the sad. Yet it cannot be bought, begged, borrowed, or stolen, for it is something that is no earthly good to anybody till it is given away. And if in the last-minute rush of Christmas buying some of our salespeople should be too tired to give you a smile, may we ask you to leave one of yours? For nobody needs a smile so much as those who have none left to give!

Practice 3  A newspaper is much more than a business; it is an institution. It reflects and influences the life of a community; it may affect even wider destinies.  It is, in its way, an instrument of government. It plays on the minds and consciences of man. It may educate, stimulate, assist, or it may do the opposite. It has, therefore, a moral as well as a material existence, and its character and influence are in the main determined by the balance of these two factors. It may make profit or power its first object, or it may conceive itself as fulfilling a higher and more exacting function.  Character is a subtle affaire, and has many shades and sides. It is not a thing to be much talked about, but rather to be felt. It is the slow deposit of past actions and ideas.  At the perils of its soul, a newspaper must see that the news it supplies is not tainted. Neither in what it gives, nor in what it does not give, nor in the mode of presentation, must the unclouded face of truth suffer wrong. Comment is free, but facts are sacred. “Propaganda,” so called, by this means is hateful. The voice of opponents no less than that of friends has a right to be heard. Comment also is justly subject to a self-imposed restraint. It is well to be frank; it is even better to be fair. This is an ideal. Achievement in such matters is hardly given to man. Perhaps none of us can attain to it in the desirable measure. We can but try, ask pardon for shortcomings, and there leave the matter.  One of the virtues, perhaps the chief virtue, of a newspaper is its independence. Whatever its position or character, it should have a soul of its own.  That is the path of self-respect—it is also the path of success. And what a work it is! How multiform, how responsive to every need—and every incident of life! What illimitable possibilities of achievement and of excellence!  To the man, whatever his place on the paper, nothing should satisfy short of the best. It is here that ability counts and that character counts, and it is on these that a newspaper, if it is to be worthy of its power and duty, must rely.

(阅读理解题)It is a great truth because once we truly understand and accept it, then life is no longer difficult. Most do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. It seems to them that difficulties stand for a special kind of suffering especially forced on them or else on their families, their class, or even their nation. What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause sadness, or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes a lot of problems, life is always difficult and is full of pain as well as joy. Yet, it is in this whole process of solving problems that life has its meaning. Problems are the serious test that tells us success from failure. When we want to encourage the growth of human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt, instruct ." It is for this reason that wise people learn not to fear but to welcome the pain of problems. (1). Which sentence best express the central point of the passage?
