单选题 Caesar was right. Thin people need watching. I've been watching them for most of my adult life, and I don't like what I see. When these narrow fellows spring at me, I quiver to my toes. Thin people come in all personalities, most of them menacing. You've got your "together" in person, your mechanical thin person, your condescending thin purism, your tsk-tsk thin person, your efficiency-expert thin person. All of them are dangerous. In the first place, thin people aren't fun. They don't know how to goof off, at least in the best, fat sense of the word. They've always got to be adoing. Give them a coffee break, and they'll jog around the block. Supple them with a quiet evening at home, and they'll fix the screen door and lick S & H green stamps. They say things like "there aren't enough hours in the day". Fat people never say that. Fat people think the day is too damn long already. Thin people make me tired. They've got speedy little metabolisms that cause them to bustle briskly. They're forever rubbing their bony hands together and eyeing new problems to "tackle". I like to surround myself with sluggish, inert, easygoing fat people, the kind who believe that if you clean it up today, it'll just get dirty again tomorrow. Some people say the business about the jolly fat person is a myth, that all of us chubbies are neurotic, sick, sad people. I disagree. Fat people may not be chortling all day long, but they're a hell of a lot nicer than the wizened and shriveled. Thin people turn surly, mean, and hard at a young age because they never learn the value of a hot-fudge sundae for easing tension. Thin people don't like gooey soft things because they themselves are neither gooey nor soft. They are crunchy and dull, like carrots. They go straight to the heart of the matter while fat people let things stay all blurry and hazy and vague, the way things actually are. Thin people want to face the truth. Fat people know there is no truth. One of my thin friends is always staring at complex, unsolvable problems and saying, "The key thing is fat people never say that." They know there isn't any such thing as the key thing about anything.

单选题{{B}}Passage One{{/B}} Go Ahead—Cook with It 别怕—就用它来烹饪 It's grapefruit season. From now through March, the golden orbs are ripe for the picking. And they're not just for breakfast any more. Hanging around on trees all about California: grapefruit—heavy with juice, tartly sweet, beguilingly perfumed．Round and yellow as happy faces or suns, they seem to ripe just as the general populace sinks into its annual round of post-holiday dietary self-chastisement. Coincidence? Perhaps. But we say run with it. Look beyond the obvious salvo of half a grapefruit for breakfast attacked with a jagged spoon and you'll find a marvelous fruit for peeling and eating out of hanD．There's nothing like it for inducing simultaneous feelings of gastronomic piety and delight at recapturing a long-lost pleasure. It's sensual: the aroma of essential oils as they spurt daintily from the pores of the thick skin, the ripping sound of the tenacious segments being pulled apart, the juice dripping down. And it's delicious. But don't stop there. Cook with grapefruit. Use its juice to flavor sauces. Section and scatter it. Bake with it. Candy its peel. Grapefruit is milder and sweeter than lemon, but it can be used in many of the same ways—squeezed on grilled fish, made into a brightly flavored curD．And if you're looking for gorgeous color, red grapefruit offers extra plate appeal. The notion that red grapefruit is sweeter than white or yellow grapefruit is, however, a myth, according to citrus specialists. (The story grew out of a marketing campaign by Texas growers. ) Red grapefruits get their color from lycopene, which has health benefits (its an antioxidant)but does not affect flavor. Sweetness is determined, rather, by the length of time the fruit has been hanging on a tree. A grapefruit picked in December isn't as sweet as one picked in February, so if you have a tree, just pick fruit as needed． If not, ask at your farmers market about the different varieties available, all of which have their fans. California reds include the medium-pink Rio Reds from the Caochella Valley and the Star Ruby from Central Valley (and Texas). Yellow Marsh is a familiar yellow variety and the Duncan, while not usually labeled as such in supermarkets, is a reliable white. For those who don't like the tartness of a true grapefruit, Oro Blanco—the half-grapefruit, half-acidless pummelo—is sweeter and can be used in salads. Our salad of jicama strips, thinly sliced snow peas, fresh pea sprouts (available in Asian markets)and red grapefruit sections has an appealing crunch. Its delicately harmonious flavors are pulled together with a faintly sweet dressing of grapefruit juice, tarragon and mint. The strikingly pink sauce of our baked halibut dish contrasts with the white flesh of the fish for an artful plate—and it's easy to make. Before baking, marinate the halibut in grapefruit juice with garlic and thyme. Sauce it with a reduction of grapefruit juice combined with blood orange juice, which deepens the color and softens the flavor. Then whisk in bits of cold butter for silkiness. A rich crust is a perfect foil for the tangy grapefruit curd filling in our pretty tartlets. Both grapefruit juice and lemon juice are used in the curd to focus the flavor; grapefruits zest enlivens the crust. Garnish them with whipped cream and candied grapefruit peel. For cooking, select heavy fruit, which indicates juiciness. (If you're making a batch of candied peel, however, lighter fruit will indicate more peel.) Before juicing, roll a grapefruit under your hand on the countertop to help extract the most juice. Avoid lumpy fruit, which may be over-ripe. And finally, for those whose resolute January superegos care about such things, here's a reassuring thought: Grapefruit is low in calories (40 to 60 each), high in vitamins C and A, and an excellent source of fiber. It contains no fat, sodium or cholesterol. So peel away.

单选题Whales 鲸 Whales are aquatic mammals belonging to order CetaceA．A few species live in fresh water, but most species live in the seA．They have a streamlined shape and a powerful tail to drive them forwarD．With its two large horizontal fins or flukes, the tail produces the driving force by beating strongly up and down. Flippers at the front are used for steering and balance. The hind limbs of whales have completely disappeared, apart from a few small bones inside the body. Body hair has also disappeared, giving whales a smoother outline and less resistance to water.Instead of hair, whales are insulated by a thick layer of fat, or blubber, under the skin. The blubber may be as much as 61 cm thick on some parts of the body. Besides protecting the animal against the cold, the blubber is an important food reserve. Most of the best-known whales large creatures.For example, the blue whale reaches a length of more than 30 m.However, many whales, such as dolphins and porpoises, are small.Some are only 1.5 to 1.8 m long. Whales live entirely in water.Sometimes, whales are stranded on the shore.Although they are air-breathing animals, they soon die because their great weight keeps them from expanding (opening out) the chest cavity.They can breathe easily when afloat, because the water supports most of their weight. The bottle-nosed whale has been known to stay under water for about two hours.The sperm whale can dive down to depths of 500 fathoms.Such long and deep dives are unusual.Most dives last between 10 and 30 minutes.Whales have special mechanisms that help them to stay under water.When they breathe, they renew about nine-tenths of the air in their lungs.When human beings breathe in, only about one-fourth of the air is renewed.Whales therefore have a fairly large supply of fresh air to start with.They also have an additional oxygen supply in the muscles, where air is loosely held in combination with a pigment called myohaemoglobin.Another thing that helps whales hold their breath for long periods of time is their low sensitivity to carbon dioxide in the blood.(It is the carbon dioxide building up in human blood that affects the brain and makes the human being take another breath.) When a whale surfaces to renew its air supply, it needs only to push the top of its snout out of the water.This is because the nostril or blowhole is at the top of the heaD．The expelled air is forced out strongly to form the spout or blow. Living whales are divided into two groups—tooth whales and whalebone whales.Tooth whales, which include most species, generally have many conical teeth and eat mainly squids and fishes.The killer whale feeds on seals.One African river dolphin feeds mostly on plants.Other tooth whales include the narwhal and the sperm whale. Whalebone whales have no teeth.Their mouths contain huge comblike fringes of baleen or whalebone.This horny substance is usually black.All whalebone whales feed by straining small animals from the water.The mouth is filled with water and the water is then forced out through the fringes by the tongue.The animals caught in the baleen are swept into the stomach by the tongue. All whalebone whales are large animals, which are usually found in cold seas.They include the blue whales, the right whales, and the rorquals. The future of many of the larger kinds of whales is uncertain. Whalers have killed so many blue, bowhead, humpback, and right whales that those species are threatened with extinction. Overhunting has also greatly reduced the number of fin and sei whales.Also, if the human population does not stop increasing, people may have to compete with whales for food in the seA．Some nations have begun fishing for krill.Krill is the chief food of whales in Antarctic waters.
