单选题{{B}}Part B{{/B}}Directions: In the following article, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list A-G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the blanks. Long before man lived on the Earth, there were fishes, reptiles, birds, insects, and some mammals. Although some of these animals were ancestors of kinds living today, others are now extinct, that is, they have no descendants alive now. Nevertheless, we know a great deal about many of them because their bones and shells have been preserved in the rocks as fossils. 41.______That kind of rock in which the remains are found tells us much about the nature of the original land, often of the plants that grew on it, and even of its climate. When an animal dies, the body, its bones, or shell, may often be carried away by streams into lakes or the sea and there get covered up by mud. If the animal lived in the sea its body would probably sink and be covered with mud. More and more mud would fall upon it until the bones or shell become embedded and preserved. 42．______Thus it follows that there must be many kinds of mammals, birds, and insects of which we know nothing, 43．______Later forms are more complex, and among these are the sea-lilies, relations of the star-fishes, which had long arms and were attached by a long stalk to the sea bed, or to rocks. There were also crab-like creatures, whose bodies were covered with a horny substance, The body segments each had two pairs of legs, one pair for walking on the sandy bottom, the other for swimming. The head was a kind of shield with a pair of compound eyes, often with thousands of lenses. They were usually an inch or two long but some were 2 feet. The shellfish have a long history in the rock and many different kinds are known. Of these, the ammonites are very interesting and important. They have a shell composed of many chambers, each representing a temporary home of the animal. As the young grew larger it grew a new chamber and sealed off the previous one. Thousands of these can be seen in the rocks on the Dorset Coast. The first animals with true backbones were fishes, first known in the rocks of 375 million years ago. About 300 million years ago the amphibians, the animals able to live both on land and in water, appeared. They were giant, sometimes 8 feet long, and many of them lived in the swampy pools in which our coal seam, or layer, formed. 44．______About 75 million years ago the Age of Reptiles was over and most of the groups died out. The mammals quickly developed, and we can trace the evolution of many familiar animals such as the elephant and horse. 45．______ [A] The best index fossils tend to be marine creatures. These animals evolved rapidly and spread over large areas of the world. [B] The amphibians gave rise to the reptiles and for nearly 150 million years these were the principal forms of life on land, in the sea, and in the air. [C] Many of the later mammals, though now extinct, were known to primitive man and were featured by him in cave paintings and on bone carvings. [D] Nearly all of the fossils that we know were preserved in rocks formed by water action, and most of these are of animals that lived in or near water. [E] The earliest animals whose remains have been found were all very simple kinds and lived in the sea. [F] Many factors can influence how fossils are preserved in rocks. Remains of an organism may be replaced by minerals, dissolved by an acidic solution to leave only their impression, or simply reduced to a more stable form. [G] From them we can tell their size and shape, how they walked, the kind of food they ate. Very occasionally the rocks show impression of skin, so that, apart from color, we can build up a reasonably accurate picture of an animal that died millions of years ago.

单选题Passage Three If you had asked me then if I would accept a job as a restaurant critic for The New York Times, or any established publication, I would have replied, without a second thought, "Of course not!" And not just because I did not want to think of myself as an ambitious sort. Working in restaurants was honest labor; anyone could see that. Writing about them for the mainstream press was not; it felt like joining the enemy. But reviewing was fun, so much fun that when mainstream publishers started paying me for my opinions, I didn't do the decent thing. Before I knew it, I had stopped cooking professionally. Then I stopped cooking altogether. "She's joined the leisure class," my friends said. I disarmed my critics by inviting them along; nobody I knew could afford to eat out and nobody refuseD. We went with equal amounts of guilt and pleasure, with a feeling that we were trespassing on the playgrounds of the rich. We didn't belong in those starchy restaurants. We always got the worst table. And then, because I didn't own a credit card, I had to pay in cash. The year turned into two, and three, and more. I got a credit carD. I got good clothes. I was writing for increasingly prestigious publications. Meanwhile, a voice inside me kept whispering, "How could you?" When I receive weekly letters from people who think it is indecent to write about $100 meals while half the world is hungry, the voice yacks right along. "They're absolutely right," it whispers. And when it asks, "When are you going to grow up and get a real job?" it sounds a lot like my mother. And just about then is when I tell the voice to shut up. Because when my mother starts telling me that all I'm doing with my life is telling rich people where to eat, I realize how much the world has changed. Yes, there are still restaurants where rich people go to remind themselves that they are different from you and me. But there are fewer and fewer of them. As American food has come of age, American restaurants have changeD. Going out to eat used to be like going to the opera; today, it is more like going the movies.
