The risers are higher, or there are more of them, or something. Maybe this is because it is so much farther today from the first to the second floor, but Ive

3、 noticed it is getting harder to make two steps at a time any more. Nowadays it is all I can do to make one step at a time. Another thing Ive noticed is the small print theyre using lately. Newspapers are getting farther and farther away when I have them, and I have to squint to make them out. The o

4、ther day I had to back halfway out of a telephone booth in order to read the number on the coin box. It is obviously ridiculous to suggest that a person my age needs glasses, but the only other way I can find out whats going on is to have somebody read aloud to me, and thats not too satisfactory bec

5、ause people speak in such low voices these days that I cant hear them very well. Everything is farther than it used to be. Its twice the distance from my house to the station now, and theyve added a fair-sized hill that I never noticed before. The trains leave sooner too. Ive given up running for th

6、em, because they start faster these days when I try to catch them. You cant depend on timetables any more, and its no us asking the conductor. I ask him a dozen times a trip if the next station is where I get off, and he always says it isnt. How can you trust a conductor like that? Usually I gather

7、up my bundles and put on my hat and coat and stand in the aisle a couple of stops away, just to make sure I dont go past my destination. Sometimes I make doubly sure by getting off at the station ahead. A lot of other things are different lately. Barbers no longer hold up a mirror behind me when the

8、yve finished, so I can see the back of my head, and my wife has been taking care of the tickets lately when we go to the theater. They don t use the same material in clothes any more, either. Ive noticed that all my suits have a tendency to shrink, especially in certain places such as around the wai

9、st or in the seat of the pants, and the laces they put in shoes nowadays are harder to reach. Revolving doors revolve much faster than they used to. I have to let a couple of openings go past me before I jump in, and by the time I get up nerve enough to jump out again Im right back in the street whe

10、re I started. It s the same with golf. Im giving it up because these modern golf balls they sell arc so hard to pick up when I stoop over. Ive had to quite driving, too; the restrooms in filling stations are getting farther and farther apart. Usually I just stay home at night and read the papers, pa

11、rticularly the obituary columns. Its funny how much more interesting the obituary columns have been getting lately. Even the weather is changing. Its colder in winter and the summers are hotter than they used to be. Id go away, if it wasnt so far. Snow is heavier when I try to shovel it, and I have

12、to put on rubbers whenever I go out, because rain today is wetter than the rain we used to get. Draughts are more severe too. It must be the way they build windows now. People are changing too. For one thing, they re younger than they used to be when I was their age. I went back recently to an alumn

13、i reunion at the college I graduated from in 1943-that is, 1933-1 mean, 1923-and I was shocked to see the mere tots theyre admitting as students these days. The average age of the freshman class couldnt have been more than seven. They seem to be more polite than in my time, though; several undergrad

14、uates called me “Sir,“ anti one of them asked me if he could help me across the street. On the other hand, people my own age. are so much older than I am. I realize that my generation is approaching middle age (I define middle age roughly as the period between 21 and 110) but there is no excuse for

15、my classmates tottering into a state of advanced senility. I ran into my old roommate at the bar, and he d changed so much that he didnt recognize me. “Youve put on a little weight, George,“ I said “Its this modern food,“ George said,“ It seems to be more fattening.“ “How about another martini?“ I s

16、aid. “Have you noticed how much weaker the martinis are these days?“ “Everything is different,“ said George. “Even the food you get. Its more fattening.“ “How long since Ive seen you, George?“ I said. “It must be several years.“ “I think the last time was right after the election,“ said George. “Wha

17、t election was that?“ George thought for a moment. “Harding.“ I ordered a couple more martinis. “Have you noticed these martinis are weaker than they used to be? I said. “It isnt like the good old days,“ George said. “Remember when wed go down to the speak, and order some Orange Blossoms, and maybe

18、pick up a couple of flappers? Boy, could they neck? Hot diggety !“ “You used to be quite a cake-eater, George,“ I said. “Do you still do the Black Bottom?“ “I put on too much weight,“ said George. “This food nowadays seems to be more fattening.“ “I know,“ I said, “You mentioned that just a minute ag

19、e.“ “Did I7“ said George. “How about another martini?“ I said. “Have you noticed the martinis arent as strong as they used to be?“ “Yes,“ said George, “You said that twice before.“ “Oh,“ I said.

37、55.00)Recent research had claimed that an excess of positive ions in the air could have an ill effect on peoples physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance. If the balance becomes dis

38、turbed and a larger proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes or when winds such as the Mistral, Foehn, Hamsin or Sharav are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing ma

39、de of man-made fibers, or from TV sets, duplicators or computer display screens. When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea or even mental disturb

40、ance. Animals are also found to be affected, particularly before earth- quakes; snakes have been observed to come out of hibernation, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals

41、 in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains,

42、or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls. To increase the supply of negative ions indoors, some scientists recommend the use of ionisers; small portable

43、machines that generate negative ions. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive in resea

44、rch. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment. After all, it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat. （分数：177.50）(1).What
