Long bus rides are like television shows. They have a beginning,a middle,and an end—with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. “Buy Super Clean Toothpaste. ”“Drink Root Beer. ” “Fill up with Pacific Gas. ” Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of “You Need It! Buy It Now !,’The beginning of the ride is comfortable and somewhat exciting, even if you've traveled that way before. Usually some things have changed—new houses, new buildings, sometimes even a new road. (76) The bus driver has a style of driving and it ’ s fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring, the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you ’ ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there ’ s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. (77) By now you ’ ve sat with your legs crossed,with your hands in your lap,with your hands on the armrests—even with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit.
According to the passage, what do the passengers usually see when they are on a long bus trip?
A.Buses on the road.
B.Films on television.
C.Advertisements on the board.
D.Gas stations.
For the past decade, Bill Keaggy, 33, the features photo editor at The St. Louis Post-Dispatch, has been collecting grocery lists and since 1999 has been posting them online at www.grocerylists.org. The collection, which now numbers more than 500 lists, is strangely addictive. The lists elicit twofold curiosity — about the kind of meal the person was planning and the kind of person who would make such a meal. What was the shopper with vodka, lighters, milk and ice cream on his list planning to do with them? In what order would they be consumed? Was it a he or a she? Who had written "Tootie food, kitten chow, bird food stick, toaster scrambles, coffee drinks"? Some shoppers organize their lists by aisle; others start with dairy, go to cleaning supplies and then back to dairy before veering off to Home Depot. A few meticulous ones note the price of every item. One shopper had written in large letters on an envelope, simply, "Milk".
The thin lines of ink and pencil jutting and looping across crinkled and torn pieces of paper have a purely graphic beauty. One of life's most banal duties, viewed through the curatorial lens, can somehow seem pregnant with possibility. It can even appear poetic, as in the list that reads "meat, cigs, buns, treats".
One thing Keaggy discovered is that Dan Quayte is not alone — few people can spell bananas and bagels, let alone potato. One list calls for "suchi" and "strimp" . "Some people pass judgment on the things they buy. " Keaggy says. At the end of one list, the shopper wrote "Bud Light" and then "good beer". Another scribbled "good loaf of white bread". Some pass judgment on themselves, like the shopper who wrote "read, stay home or go somewhere, I act like my morn, go to Kentucky, underwear, lemon. "People send messages to one another, too. Buried in one list is this statement: "If you buy more rice, I'll punch you. "And plenty of shoppers, like the one with both ice cream and diet pills on the list, reveal their vices.
What would people usually do with their grocery list after shopping?
A.Buying what it is scrawled on the paper.
B.Recording the shorthand of where we shop.
C.Throwing it into the dustbin.
D.Posting it on the Internet.
And this main question for the poor of England—for the poor of all countries—is wholly omitted in every writing on the subject of wealth. Even by the laborers themselves, the operation of capital is regarded only in its effect on their immediate interests, never in the far more terrific power of its appointment of the kind and the object of labor. It matters little, ultimately, how much a laborer is paid for making anything, but it matters fearfully what the thing is which he is compelled to make. If his labor is so ordered as to produce food, fresh air, and fresh water, no matter that his wages are low, the food and the fresh air and water will be at last there, and he will at last get them. But if he is paid to destroy food and fresh air, or to produce iron bars instead of them, the food and air will finally not be there, and he will not get them, to his great and final inconvenience. So that, conclusively, in political as in household economy, the great question is not so much what money you have in your pocket, as what you will buy with it and do with it.
The author gives the example of a tollgate in the first paragraph to indicate that
A.it is an act of robbery.
B.it is an impractical plan.
C.it will break the law.
D.it can make people rich.
Question 24 to 27 are based on the following passage.
Scientists can learn about man by studying animals, such as mice, rats and monkeys. The scientists in a laboratory areexperimenting on mice and they are studying the relationship between diet and health.
In this experiment, the scientists are studying the relationship between the amount of food the mice can eat and theirhealth. The mice are in three groups. All these groups are receiving the same healthy diet. But the amount of food that eachgroup is receiving is different. The first group is eating one cup of food each day, the second two cups, and the third threecups.
After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group arethinner than normal mice but they are more active. Most of the day, they are running, playing with one another, and using theequipment in their cages. Also, they are living longer. Mice usually live for two years, while most of the mice in this groupare still alive after three years.
The second group of mice is of normal weight. They are healthy, too. They are active, but not as active as the thinnermice. But they are only living about two years.
The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating orsleeping. They are not active. These mice are living longer than the scientists thought —about a year and a half, but they arenot healthy. The are sick more often than the other two groups.
