We asked a lady, who replied that she thought you could tell a well-mannered person by the way they occupied the space around them —for example, when such a person walks down a street he or she is 2(constant) aware of others. Such people never bump into other people. However, a 3(two) person thought that this was 4(much) a question of civilized behavior than good manners. Instead, this other person told us a story, which he said was quite well known, 5an American who 6(invite) to an Arab meal in one of the countries of the Middle East. The American hadn’t been told very much about the kind of food he might expect. If he had known about Arab food, he might have behaved 7 (good). Immediately before him was a very flat piece of bread that looked, to him, very much like a napkin (餐巾). 8(pick) it up, he put it into his collar, so that it fell across his shirt. His Arab host, 9had been watching, said nothing, but 10(immediate) copied the action of his guest. And that, said this second person, was a fine example of good manners. 2 There are times when people are so tired that they fall asleep almost anywhere. We can see a lot of people sleeping on the bus or train on their way home 1work in the evening. A man will be reading the newspaper, and seconds later it appears as if he is trying to eat it. Or he will fall asleep on the shoulder of the stranger sitting next to him. Another place where unplanned short sleep goes on is in the lecture hall 2 a student will start snoring so loudly that the professor has to ask another student 3(shake) the sleeper awake. A more 4(embarrass) situation occurs when a student starts falling into sleep and 5weight of the head pushes the arm off the desk, and the movement carries the rest of the body along. The student wakes up on the floor with no memory of getting there. The 6(bad) time to fall asleep is when driving. Police reports are full of 7(accident) that occur when people fall into sleep and go off the road. If the drivers are lucky, they are not 8(serious) hurt. One woman’s car, for example, we nt into the river. She woke up in four feet of water and thought that it 9(rain). When people are really 10 (tire), nothing will stop them from falling asleep — no matter where they are. 3 I decided a few months ago I was going to treat myself to a 4-day getaway from Los Angeles and visit Chicago. I booked an airplane ticket on a website. I also found a travel website where a discounted 3-night stay was purchased from a recently 1(open) hotel. About three weeks 2the trip, I had other plans and had to cancel the trip. Only then did I 3(realize) the room, while transferable to another person, couldn’t 4(change) to a later date and wasn’t refundable. I tried selling it but with no success. Five days before the “big weekend” I gave up 5(try) and decided I would contact some friends who lived in Chicago and would offer someone a free family vacation. After 6(contact) a handful of people, all of
