Like Germany's autobahn, the Smart has no speed limit; unlike the autobahn, it's virtually barren. Every 45 minutes or so, a roadhouse appears mirage-like on the horizon, offering gas, beer, motel-style. lodging, and a little "Where ya from, mate？" Aside from that, the land presents itself the way God made it. Hour by hour, sandy red earth gives way to spindly trees, brown escarpments, termite mounds as tall as kindergartners, and not much else. No cell phone coverage, no radio stations. There's nowhere else on earth to be so isolated while on good roads in your aver-age rental car.
The pleasure of a Stuart drive is partly in stumbling across artifacts from man's attempts to make use of the bush. Beside the gas station in Barrow Creek (kilometer 294), a wooden telegraph repeater station from the early 1870s stands abandoned but perfectly preserved by the dry desert air. There's another in the expanse north of Tennant Creek (541). Barely rusted bits of telegraph wire and antique bottles still litter the grounds of both. The eerie ruins at Gorrie Airfield (1,103) once housed 6,500 personnel in World War II. Today, there are ghostly scraps of gray bitumen leading to an old fighter runway that's over a mile long.
The walls inside most of the bush pubs along the highway are stapled over with bras, under-wear, foreign currency, and business cards-a few of mine included-left by visitors from around the world. Basic rooms cost about $ 35; given the volume of cold Victoria Bitter on tap, by bed-time most customers aren't in a state to quibble over thread counts. Just about every pit stop is run by someone who could pass as the main character in a novel.
According to the passage, Darwin in the first paragraph is _______.
A．the name of a well-known scientist.
B．the name of an island in Timor Sea.
C．the name of a city standing at the end of the Smart Highway.
D．the name of a pub in the center of Australian desert.

Mickey Mouse was conceived the next year during a cross-country train ride, according to the "official" company history. Walt Disney had just been forced to give up the Oswald rights to his cruel New York distributor, who had exercised copyright control over the character.
On the ride back home to Los Angeles, Disney made up a little mouse named Mortimer. His wife, Lillian, thought the name too pompous(华而不实的) and suggested Mickey.
Steamboat Willie, Mickey's screen debut, was an instant hit, arriving in the same year, a time when technological advances in motion pictures, radio and the phonograph(留声机) were transforming mass culture. By the end of the 1930s, Mickey had starred in more than 100 cartoons.
Mickey gradually transformed both physically and spiritually. His face was rounded out and his eyes went from black ovals to white eyes with pupils in the late 1930s. His face became friendlier, less rat-like.
Mickey Mouse became the face that launched a thousand merchandise products. Watches. Pencils. Bed sheets. Alarm clocks. Telephones. He is one of the most merchandised faces ever—about $4.5 billion a year in sales—even though he's currently second to Winnie the Pooh for the Disney company.
Mickey's popularity may have declined in the 1940s, but he gained new life in the 1950s with the airing of TV's Mickey Mouse Club and the opening of Disneyland in Anaheim, California.
In the succeeding decades, Mickey has been a regular presence on television on the Disney Channel and is photographed daily alongside thousands of tourists at theme parks in California, Florida, France and Japan.
"Mickey Mouse speaks an international language," Sklar said. "When I go to Tokyo and see how kids react to Mickey Mouse the same way they do in Paris, it's reassuring that there are some things that cress international boundaries."
All from a simple cartoon. Said author Wasko: "Mickey represents a fascinating interweaving of culture, politics and economics."
Walt and his brother Roy worked together ______.
A．to create a cartoon character called Alice
B．to produce the role of Mickey
C．to resist giving up the character's rights to others
D．to make greater career success

Woman: Thank you, Chris. You know, today—with so many Americans counting calories and wanting to eat more natural foods—there are many new kinds of bread on supermarket shelves, high fiber bread, wheat germ bread, low calorie bread, to name only a few. Well, despite the variety, the principal ingredients of bread have remained the same. flour, water, and yeast. There may be a few other things added as food for the yeast to help it develop or as agents to assist the baking process, but these additives appear in minute quantities and have little effect on calories or nutrition.
Man: Well, what about the differences between white bread and whole grain bread, Alice？ Is whole grain bread really superior nutritionally？
Woman: Both have their advantages, Chris. Whole grain bread does have more fibers of course, and the bulk which the fiber provides can be useful in digestion. White bread has a finer texture. The reason that so many people feel white bread is nutritionally lacking is the bleaching process. Bleaching, which gives bread its distinctive white color, does remove many nutrients. But what many people are unaware of is that these nutrients are added back into the bread after the bleaching process. And this re-adding process has a distinct advantage for some people. One nutrient that is re-added, iron, is unbounded in white bread whereas the iron which is retained in its natural state in whole grain bread is bonded to other chemical constituents. Studies have shown that some people have difficulty absorbing the bonded iron but can readily absorb the unbounded iron in bleached white bread. Probably the soundest advice for most people is to eat some of both types of bread. And now here's a story which makes the good old days seem that much further in the past. Do you still remember the nickel candy bar that you used to buy on the way home from school when you were a child？ Well, after successive increases to 10, 15, and 20 cents, the old nickel candy bar is now going to cost you a quarter. Candy manufacturers report that the bars will be larger. But, whereas the price is increasing 25%, the average weight increase for a bar is only 14%.
Man：Thank you, Alice. We'll have more news after we return from a commercial break.
19.According to the report, what are the three main ingredients found in bread？
20.What advantage does unbounded iron offer？
21.Which of the following statements about bread is true？
22.What gives white bread its distinctive color？
(39)
A．Fiber, wheat germ and water.
B．Iron, flour and yeast.
C．Yeast, flour and fiber.
D．Flour, water and yeast.
