You never see him, but they’re with you every time you fly. They record where you are going, how fast you’re traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They’re known as the black box.　When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device’s homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.　In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.　Modern airplanes have two black boxes: a voice recorder, which tracks pilots’ conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft’s final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand（抵挡）massive force and temperatures up to 2,000℉. When submerged（潜入水中）, they’re also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they’re still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane’s black boxes were never recovered1.What does the author say about the black box?A.It ensures the normal functioning of an airplaneB.The idea for its design comes from a comic bookC.Its ability to ward off disasters is incredibleD.It is an indispensable device on an airplane2.What information could be found from the black box on the Yemeni airliner?A.Data for analyzing the cause of the crashB.The total number of passengers on boardC.The scene of the crash and extent of the damageD.Homing signals sent by the pilot before the crash3.Why was the black box redesigned in 1965?A.New materials became available by that timeB.Too much space was needed for its installationC.The early models often got damaged in the crashD.The early models didn’t provide the needed data4.What do we know about the black boxes from Air France Flight 447?A.There is still a good chance of their being recoveredB.There is an urgent need for them to be reconstructedC.They have stopped sending homing signalsD.They were destroyed somewhere near Brazil

({B)}Calories({/B)} For years now, calories have been all the rage―people are counting them and cutting them, and you’d be hard-pressed to find something at the supermarket that does not list its calories per serving somewhere on the package. But have you ever wondered what exactly a calorie is ({B)}What Is a Calorie ({/B)} A calorie is a unit of energy. We tend to associate calories with food, but they apply to anything containing energy. For example, a gallon (about 4 liters) of gasoline contains about 31,000,000 calories. Specifically, a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius (1.8 degrees Fahrenheit). One calorie is equal to 4.184 joules (焦耳), a common unit of energy used in the physical sciences. Most of us think of calories in relation to food, as in "This can of soda has 200 calories." It turns out that the calories on a food package are actually kilocalories (1,000 calories=1 kilocalorie). The word is sometimes capitalized to show the difference, but usually not. A food calorie contains 4,184 joules. A can of soda containing 200 food calories contains 200,000 regular calories, or 200 kilocalories. A gallon of gasoline contains 31,000 kilocalories. The same applies to exercise―when a fitness chart says you burn about 100 calories for every mile you jog, it means 100 kilocalories. For the duration of this article, when we say "calorie", we mean "kilocalorie"({B)}What Calories Do ({/B)} Human beings need energy to survive―to breathe, move, pump blood―and they acquire this energy from food. The number of calories in a food is a measure of how-much potential energy that food possesses. A gram of carbohydrates(碳水化合物) has 4 calories, a gram of protein has 4 calories, and a gram of fat has 9 calories. Foods are a compilation of these three building blocks. So if you know how many carbohydrates, fats and proteins are in any given food, you know how many calories, or how much energy, that food contains. If we look at the nutritional label on the back of a packet of maple-and-brown-sugar oatmeal, we find that it has 160 calories. This means that if we were to pour this oatmeal into a dish, set the oatmeal on fire and get it to burn completely (which is actually pretty tricky), the reaction would produce 160 kilocalories (remember: food calories are kilocalories)―enough energy to raise the temperature of 160 kilograms of water 1 degree Celsius. If we look closer at the nutritional label, we see that our oatmeal has 2 grams of fat, 4 grams of protein and 32 grams of carbohydrates, producing a total of 162 calories (apparently, food manufacturers like to round down). Of these 162 calories, 18 come from fat (9 cal×2g), 16 come from protein (4 cal×4g) and 128 come from carbohydrates (4 cal×32g). Our bodies "burn" the calories in the oatmeal through metabolic (新陈代谢的) processes, by which enzymes (酵素) break the carbohydrates into glucose (葡萄糖) and other sugars, the fats into glycerol (丙三醇) and fatty acids and the proteins into amino acids (氨基酸). These molecules are then transported through the bloodstream to the cells, where they are either absorbed for immediate use or sent on to the final stage of metabolism in which they are reacted with oxygen to release their stored energy.({B)}Your Caloric Needs({/B)} Just how many calories do our cells need to function well The number is different for every person. You may notice on the nutritional labels of the foods you buy that the "percent daily values" are based on a 2,000 calorie diet. 2,000 calories is a rough average of what a person needs to eat in a day, but your body might need more or less than 2,000 calories. Height, weight, gender, age and activity level all affect your caloric needs. There are several factors that regulate how many calories we need each day. Some of these considerations are your metabolic rate (新陈代谢率), physical activity level and thermic (热的) effect of food, sleep patterns, age, gender, body mass and body size. To determine your caloric intake value for building mass, multiply your body weight by 24, while multiplying your body weight by 17 to determine your approximate maintenance level caloric intake. The main function of carbohydrates is to be a source of energy for the body. In the end, energy drawn from the breakdown of glucose and glycogen (肝糖) is used to fuel muscular contractions as well as provide a "protein sparing" effect. Unlike the other macro-nutrients, proteins contain nitrogen (氮) which is important in the formation of new muscle tissue. The human body requires 22 different amino acids, which are found in protein, and can be classified as either essential or non-essential. Essential amino acids can’t be synthesized in the body, while non-essential amino acids can be. Under normal conditions, protein serves an important’ role in the maintenance, repair, and growth of body tissues. Proteins make up about 15% of your total body mass and have several roles in the body. Proteins also regulate the acid/base quality of body fluids and are necessary for muscle contractions, hormone production, and the activation of metabolic processes. In the human body, fat provides the largest store of potential energy, produces hormones, strengthens cell structures, transmits nerve impulses and provides insulation (绝热) from cold environments. Fats actually contribute to about 50% of the energy required during light and moderate exercise, and this percentage rises as the work period is prolonged.({B)}Calories, Fat and Exercise({/B)} So what happens if you take in more or fewer calories than your body bums You either gain or lose fat, respectively. An accumulation of 3,500 extra calories is stored by your body as 1 pound of fat―fat is the body’s way of saving energy for a rainy day. If, on the other hand, you bum 3,500 more calories than you eat, whether by exercising more or eating less, your body converts 1 pound of its stored fat into energy to make up for the deficit. One thing about exercise is that it raises your metabolic rate not only while you’re huffing and puffing (忙得喘不过气来) on the treadmill (踏车). Your metabolism takes a while to return to its normal pace. It continues to function at a higher level; your body bums an increased number of calories for about two hours after you’ve stopped exercising. Lots of people wonder if it matters where their calories come from. At its most basic, if we eat exactly the number of calories that we bum and if we’re only talking about weight, the answer is no a calorie is a calorie. A protein calorie is not different from a fat calorie―they are simply units of energy. As long as you bum what you eat, you will maintain your weight; and as long as you bum more than you eat, you’ll lose weight. But if we’re talking nutrition, it definitely matters where those calories originate. Carbohydrates and proteins are healthier sources of calories than fats. Although our bodies do need a certain amount of fat to function properly―an adequate supply of fat allows your body to absorb the vitamins you ingest―an excess of fat can have serious health consequences.Your caloric intake for building mass is determined by ______. A．multiplying your body weight by 24B．multiplying your body weight by 17C．your metabolic rate, physical activity level and thermic effect of foodD．your sleep patterns, age, gender, body mass and body size

【题文】Organizing Yourself Many new students find it hard to do all the study that has to be done; they find themselves putting off reading assignment, jumping from subject to another and rarely being quite certain what they are trying to do during a particular study session.

Let us suppose that you have 15 hours per week of classes and that you decide to allow yourself a 40—hour working week (a reasonable figure ,leaving you 70 waking hours for other activities). You now have to decide how to divide the remaining 25 hours of private study .Naturally the decisions you make will change from week to week according to what essays have to be written and what reading has to be done. Many people find it helpful to draw up each week a seven—day timetable showing the occasions on which they will be working privately and the particular subjects that will be studying on each occasion .By checking such a plan at times during the week ,you can see what you have done and what you have still to do :the whole plan become more manageable .There are a number of places where you can study—college library ,public library ,home ,empty classrooms ,on bus or train –and each has several obvious advantages and disadvantages .The college library is least busy in the evening , on Wednesday afternoon ,and all day Friday and Saturday.
