The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses(沖動) and feelings, and from that moment he gives up his moral(道德) freedom.

A single angry word has lost many friends. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whoever the gods would destroy they first make them mad.” “Keep cool,” says Webster, “anger is not argument.” “Be calm in arguing,” says George Herbert, “for fierceness(狂怒) makes error a fault.”

To be angry with a weak man is to prove that you are not strong yourself. “Anger,” says Pythagoras, “brings with folly and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.

Self-control is man’s last and greatest victory.

If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking also.  

What’s the main idea of the passage?

A. The importance of self- control.   B. How to conquer oneself?

C. The relation between a man’s moral freedom and his feelings.

D. A man should keep cool.

What’s the meaning of “whoever the gods would destroy they first make them mad”?

A. If you are mad, the gods will kill you.

B. If you lose your temper first, gods will kill you first.

C. If you can’t control yourself, you will be crazy.

D. If the gods want to kill you, they will make you mad first.

Which of the following is NOT true, according to passage?

A. The first and best of victories is for a man to conquer himself.

B. You will make a small mistake serious if you don’t keep cool.

C. You must measure a man’s strength by the power of the feelings which conquer him.

D. Anger brings with folly and ends with regret.

Which of the following can’t help you avoid anger, according to the passage?

A. Be calm in arguing.      B. Check your temper or anger by speaking low.

C. Keep your mouth shut.   D. Try to make the other angry first.

There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have travelled to the places. Or you can go and see a colour film. Or you can read travel books.

It would seem that there are three kinds of travel books. The first are those that give a personal, subjective(主觀的) account of travels which the author has actually made himself. if they are informative and have a good index(索引), then they can be useful to you when you are planning your travels. The second kind are those books whose purpose is to give a purely objective(客觀的) description of things to be done and seen. If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a selected guide book. The third kind are those books which are called “a guide” to some place or other. If they are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in the most practical way.

Whatever kind of travel book you choose you must make sure that it does not describe everything as “wonderful”, “excellent” or “magical”. You must also note its date of publication because travel is a very practical affair and many things change quickly in the twenty-first century. Finally, you should make sure that the contents are well presented and easy to find.

This passage is about _______.

A. how to travel                          B. how to buy travel books

C. how to read a travel book         D. travel books

The following travel books may be of use when you plan your travels except _______.

A. the book written by some people who have had the same travel experience themselves

B. the book which tells you what is worth doing and seeing based on the facts

C. the book in which a lot of big adjectives are used to draw your attention

D. the book which offers you a lot of useful information like a tour guide

A. the world is changing and so are the places you are going to visit

B. the price of the book is always changing

C. the author of the book may be different

D. the contents of the book are always the same

       In the doorway of my home, I looked closely at my 23-year-old son, Daniel. In a few hours he would be flying to France to   36   a different life. It was a transitional(過渡的) time in Daniel’s life. I wanted to   37   him some words of significance. But nothing came from my lips, and this was not the   38   time I had let such moments pass.

       When Daniel was five, I took him to the bus stop on his first day of kindergarten. He asked, “What is it going to be like, Dad? Can I do it?” Then he walked     39     the steps of the bus and disappeared inside. The bus drove away and I said nothing. A decade later, a similar   40   played itself out. I drove him to college. As I started to leave, I tried to think of something to say to give him  41    and confidence as he started this new stage of life. Again, words   42   me.

       Now, as I stood before him, I thought of those    43   opportunities. How many times have I let such moments   44   ? I don't find a quiet moment to tell him what they have   45   to me. Or what he might want to face in the years   46  . Maybe I thought it was not necessary to say anything.

       What does it matter in the course of a lifetime if a father never tells a son what he really thinks of him?   47   as I stood before Daniel, I knew that it did matter. My father and I loved each other. Yet, I always   48   never hearing him put his    49   into words. Now I could feel my palms sweat and my throat tighten. Why is it so   50   to tell a son something from the heart?

       My mouth turned dry, and I knew I would be able to get out only a few words clearly. “Daniel,” I said, “If I could have picked, I would have picked you.” That's all I could say. He hugged me. For a moment, the world   51   , and there were just Daniel and me. He was saying something, but tears misted my eyes, and I couldn't understand what he was saying. All I was   52   of was the stubble(短須) on his chin as his face pressed    53    mine. What I had said to Daniel was   54   . It was nothing. And yet, it was    55     .
