4 图1是交流发电机模型示意图．在磁感应强度为B的匀强磁场中，有一矩形线圈abcd可绕线圈平面内垂直于磁感线的OO˝轴转动，由线圈引起的导线ae和df分别与两个跟线圈一起绕OO˝转动的金属圈环相连接，金属圆环又分别与两个固定的电刷保持滑动接触，这样矩形线圈在转动中就可以保持和外电路电阻R形成闭合电路．图2是线圈的主视图，导线ab和cd分别用它们的横截面来表示．已知ab长度为L 1，bc长度为L 2，线圈以恒定角速度ω逆时针转动．（只考虑单匝线圈）（1）线圈平面处于中性面位置时开始计时，试推导t时刻整个线圈中的感应电动势e 1 的表达式；（2）线圈平面处于与中性面成φ 0夹角位置时开始计时，如图3所示，试写出t时刻整个线圈中的感应电动势e 2的表达式；（3）若线圈电阻为r，求线圈每转动一周电阻R上产生的焦耳热．（其它电阻均不计）
5 Organic foods are produced according to certain production standards, meaning they are grown without the use of conventional pesticides, or chemical fertilizers and that they were processed without food additives. Livestock are raised without the routine use of antibiotics（抗生素）or growth hormones. In most countries, organic produce must not be genetically modified. They may also be required to be produced using energy-saving technologies and packaged using recyclable materials when possible. Early consumers interested in organic food would look for non-chemically treated, fresh or minimally processed food. They mostly had to buy directly from growers: “Know your farmer, know your food” was the motto. Personal definitions of what constituted ( 组成)“organic” were developed through first-hand experience: by talking to farmers, seeing farm conditions, and farming activities. Historically, organic farms were relatively small family-run farms — which is why organic food was once only available in small stores or farmers’ markets. However, since the early 1990s organic food has had growth rates of around 20% a year. As of April 2008, organic food accounts for 1 - 2% of food sales worldwide. Currently organic food production is legally regulated. Many countries require producers to obtain organic certification in order to market food as organic. Several studies have attempted to examine and compare conventional and organic systems of farming. The general consensus（共同看法）is that, in the short term, organic farming is less damaging for the following reasons: ● Organic farms do not release synthetic pesticides (合成农药) into the environment — some of which have the potential to harm soil, water and local wildlife. ● Organic farms are better than conventional farms at keeping diverse ecosystems, i.e., populations of plants and insects, as well as animals. ● Organic farms are more energy efficient and produce less waste. Another report published in March 2008 by The Organic Center claims that organic food is on average 25% more nutritious than conventional food. However, many critics believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems. And organic products cost 10 to 40% more than similar conventionally produced products. Processed organic foods in supermarkets are 65% more expensive. 1. Early consumers knew what food was “organic” by _______. A. firsthand experience B. the “certified organic” label tag C. its packaging D. examining its organic certification 2. We can infer that _______. A. in America, organic food can only be bought in small stores or farmers’ markets B. organic food is also available in large supermarkets at present C. organic food is produced by large-scale farms D. organic food is often beautifully packaged 3. According to the passage, organic food is considered as _______. A. junk food B. delicious snacks C. green food D. conventional food 4. What is the main idea of the last paragraph? A. The benefits of organic food. B. The cost of organic food. C. The disadvantages of organic food. D. Organic food and conventional food. 5. Which of the following statements does NOT support the view that organic farming is more environment-friendly? A. Organic food is generally thought to be more nutritious. B. Organic farms are more energy efficient and produce less waste. C. Organic farms are better than conventional farms at maintaining varieties of plants, insects and animals. D. Organic farms do not release synthetic pesticides into the environment.
