Section_ⅣLearning_about_Language_&_Using_Language CHEMICAL① OR ORGANIC② FARMING?‎ Over the past half century, using chemical fertilizers③ has become very common in farming. Many farmers welcomed them as a great way to stop crop disease and increase production④. Recently, however, scientists have been finding⑤ that longterm use of these fertilizers can cause damage to the land and, even more dangerous, to people’s health.‎ What are some of the problems caused by chemical fertilizers⑥？ First, they damage the land by killing the helpful bacteria⑦ and pests⑧ as well as the harmful ones. Chemicals also stay in the ground and underground water for a long time. This affects crops and, therefore, animals and humans, since chemicals get inside the crops and cannot just be washed off. These chemicals in the food supply build up⑨ in people’s bodies over time⑩. Many of these chemicals can lead to⑪ cancer or other illnesses. In addition, fruit, vegetables and other food grown with chemical fertilizers⑫ usually grow too fast to be full of much nutrition⑬. They may look beautiful, but inside there is usually more water than vitamins and minerals⑭.‎ ‎①chemical/’kemIkl/adj.化学的；关于化学的 ‎②organic/ɔː’ɡænIk/adj.有机的；器官的；组织的 organic farming 有机耕作 ‎③fertilizer/’fɜːtIlaIzə/n.肥料；化肥 chemical fertilizer 化肥 ‎“over the past＋时间段”常与现在完成时连用；动名词短语using chemical fertilizers作主语，谓语动词用单数。‎ ‎④production/prə’dʌkʃn/n.生产；制造 to stop ... production为不定式短语作way的定语。‎ ‎⑤have been finding是现在完成进行时形式，表示动作从过去持续到现在，而且目前还在进行中。‎ ‎⑥过去分词短语caused by chemical fertilizers作定语，相当于定语从句that/which are caused by chemical fertilizers。‎ ‎⑦bacteria/bæk’tIərIə/n.(bacterium/bæk’tIərIəm/的复数形式)细菌 ‎⑧pest/pest/n.害虫；害兽；害鸟 ‎⑨build up逐渐增强；建立；开发 ‎⑩over time 随着时间的推移 ‎⑪lead to(＋n./pron.)导致；造成(后果)‎ ‎⑫过去分词短语grown with chemical fertilizers作后置定语。‎ ‎⑬nutrition/njuː’trIʃn/n.营养；滋养；食物 ‎⑭mineral/’mInərəl/n.矿物；矿石 化学耕作还是有机耕作？‎ ‎[第1～2段译文]‎ 在过去的半个世纪里，在耕作中使用化肥已经非常普遍。很多农民喜欢使用化肥，把它们作为防治农作物病虫害和提高产量的重要手段。然而，最近科学家发现长期使用这些肥料会造成土地受损，甚至更危险的是，会对人们的健康造成危害。‎ 化肥带来的问题有哪些呢？首先，化肥在杀死病菌和害虫的同时也会杀死有益的细菌和昆虫，从而破坏土地。化学物质还会在地里和地下水中保存很长时间，而这会影响到农作物，进而影响到动物和人类，因为化学成分会进入农作物中，并且不能被冲洗掉。随着时间的推移，食物中的这些化学成分会在人体中堆积。这里面有很多化学成分能导致癌症或其他疾病。另外，施过化肥的水果、蔬菜和其他食物通常生长得过快而营养不足。它们表面上很好看，但是里面通常是含过多的水分，而不是维生素和矿物质。‎ With these discoveries⑮， some farmers and many customers are beginning to turn to organic farming. Organic farming is simply farming without using any chemicals. They focus on⑯ keeping their soil⑰ rich and free of disease. A healthy soil reduces⑱ disease and helps crops grow strong and healthy. Organic farmers, therefore, often prefer using natural waste from animals as fertilizer. They feel that this makes the soil in their fields richer in⑲ minerals and so more fertile⑳. This also keeps the air, soil, water and crops free from chemicals.‎ Organic farmers also use many other methods to keep the soil fertile. They often change the kind of crop in each field every few years, for example, growing corn or wheat and then the next year peas or soybeans. Crops such as peas of soybeans put important ‎ minerals back into the soil, making it ready for crops such as wheat or corn that need rich and fertile soil. Organic farmers also plant crops to use different levels of soil, for example, planting peanuts that use the ground’s surface followed by vegetables that put down deep roots. Some organic farmers prefer planting grass between crops to prevent wind or water from carrying away the soil, and then leaving it in the ground to become a natural fertilizer for the next year’s crop. These many different organic farming methods have the same goal: to grow good food and avoid damaging the environment or people’s health.‎ ‎⑮discovery/dI’skʌvərI/n.发现；发觉 ‎⑯focus on(＝concentrate on)集中(注意力、精力等)于 ‎⑰soil/sɔIl/n.土壤 ‎⑱reduce/rI’djuːs/vt.减少；减缩 ‎⑲be rich in富含……；……的含量高 ‎(反)be poor/low in ……的含量低；缺乏……‎ ‎⑳fertile/’fɜːtaIl/adj.肥沃的；富饶的 keep ...free from/of使……免受(影响、伤害等)；使……不含(有害物)‎ 动词不定式短语to keep the soil fertile作目的状语；keep是使役动词，这是“keep＋宾语＋宾补”结构。‎ 现在分词短语growing corn or wheat and then the next year peas or soybeans作状语。‎ soybean/’sɔIbiːn/n.(＝soyabean)大豆 现在分词短语making it ready for crops ...作结果状语，表示一种必然的结果，这里make的用法跟前面keep的用法一致。‎ 现在分词短语planting ...作状语；两个that都引导定语从句，分别修饰peanuts和vegetables。‎ root/ruːt/n.根；根源 动词不定式短语to grow good food and avoid damaging the environment or people’s health说明goal的内容。‎ avoid doing sth.避免做某事 ‎[第3～4段译文]　　‎ 由于这些发现，一些农民和许多消费者开始转向有机耕作。有机耕作就是不用任何化学肥料的耕作。他们关心的是保持土壤肥沃并且免受病害。健康的土壤会减少病虫害并且帮助农作物茁壮成长。因此，有机耕作的农民经常喜欢把天然的动物粪便当作肥料。他们认为这样会使地里的土壤更富含矿物质，因而也会更加肥沃，同时还可以让空气、土壤、水以及农作物不受化学物质的污染。 有机耕作的农民也使用很多其他的方法来保持土壤肥沃。在同一块地里，他们经常每隔几年就换种农作物。例如，种玉米或小麦后来年再改种豌豆或大豆。像豌豆或大豆这样的农作物将重要的矿物质带回土壤，从而使之适宜于种植要求土壤肥沃的农作物，比如小麦或玉米。有机耕作的农民还种植多种农作物来利用不同层次的土壤。比如，他们先种植生长于浅层土壤的花生，然后再种植生根于深层土壤的蔬菜。还有一些有机耕作的农民喜欢在农作物之间种草，以防止水土流失，并且把草留在地里，从而成为来年农作物的天然肥料。这些不同的有机耕作的方法有着同样的目标：种植好的粮食，并且避免损害环境或者人们的健康。‎ Step 1　Read the text quickly and then match each paragraph with its main idea.‎ ‎1．Para. ‎1　‎A．Problems caused by chemical fertilizers.‎ ‎2．Para. 2 　B．Farmers and customers turn to organic farming ‎3．Para. ‎3　‎C．Long term use of chemical fertilizers can cause damage to the land and people’s health.‎ ‎4．Para. 4　D．Other methods to keep the soil fertile.‎ 答案：1～4　CABD Step 2　True (T) or False (F)．‎ ‎1．Organic farmers prefer using natural waste from animals and chemical fertilizers.(　　)‎ ‎2．Using natural waste makes the soil richer in minerals and so more fertile.(　　)‎ ‎3．Using organic farming methods is to grow good food and to avoid damaging the environment or people’s health.(　　)‎ ‎4．Using chemical fertilizers has become very common in farming over the past half century.(　　)‎ ‎5．Chemical fertilizers only kill harmful bacteria and pests.(　　)‎ 答案：1～5　FTTTF Step 3　Choose the best answers according to the text.‎ ‎1．From the passage, we can see organic farmers are those who ________.‎ A．grow crops with chemical fertilizers B．grow crops with natural fertilizers C．produce organic fertilizers D．care for the environment ‎2．From the fourth paragraph, we know that ________.‎ A．it’s not good to plant grass between crops B．peanuts use the surface of soil C．peas and soybeans should be grown together with corn and wheat D．vegetables that put down deep roots are harmful to the soil ‎3．Farmers ________ so that the soil may not get exhausted.‎ A．grow the same crops year after year B．use natural fertilizers C．change crops every few years D．use chemical fertilizers ‎4．How many ways do the organic farmers have to keep their soil fertile and healthy?‎ A．3.　　　　　　　　　 　B．4.‎ C．5.

In one hand, you're holding a conventionally grown Granny Smith apple. In your other hand, you have one that's been organically grown. Both apples are firm, shiny and green. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.‎ The conventionally grown apple costs less and is a proven family favorite. But the organic apple has a label that says “USDA Organic”. Does that mean it's better? Safer? More nutritious? Become a better informed consumer for your next trip to the supermarket. Several differences between organic and nonorganic foods exist. The word “organic” refers to the way farmers grow and process agricultural products, such as fruits, vegetables, grains, dairy products and meat. Organic farming practices are designed to encourage soil and water conservation and reduce pollution. Farmers who grow organic produce and meat don't use conventional methods to fertilize, control weeds or prevent livestock disease.‎ Here are other differences between conventional farming and organic farming：‎ Conventional farmers Organic farmers Apply chemical fertilizers to promote plant growth.‎ Apply natural fertilizers to feed soil and plants.‎ Apply insecticide to reduce pests and disease.‎ Use beneficial insects and birds to reduce pests and disease.‎ Give animals antibiotics, growth hormones and medications to prevent disease and promote growth.‎ Give animals organic foods and allow them access to the outdoors. Use preventive measures — such as a balanced diet and clean housing — to help minimize disease.‎ ‎*Organic or not Check the label The U．S. Department of Agriculture (USDA) has established an organic certification program that requires all organic foods to meet strict government standards. These standards regulate how such foods are grown, handled and processed. Any farmer or food manufacturer who labels and sells a product as organic must be USDA certified as meeting these standards. Only producers who sell less than D|S ‎5,000 a year in organic foods are exempt (免除) from this certification.‎ If a food bears a USDA Organic label, it means it's produced and processed according to the USDA standards.

It is by reading that you learn much of what you need to know for your different school subjects. __1__ Here are some suggestions on how to be a better reader.‎ Know your reading purpose. __2__ The kind of reading you do in class or for your homework is different from how you read a novel for pleasure in the summer vacation. If you know your reading purpose, you can choose the best reading method.‎ Use all the information in the book. Good textbooks are wellorganized, with titles, subtitles, introductions, summaries or conclusions. Many books also have pictures with captions (说明文字). __3__ Another aspect of good writing is that each paragraph has a topic sentence. If you concentrate on understanding the topic sentence, this may help you to understand what comes next.‎ ‎__4__ You can't really expect to understand a difficult book if you are trying to read in the same room with the television on and your little brother distracting (使某人分心) you. The same goes for reading on the bus on the way to school. You can't expect to read a textbook and listen to music at the same time either. Try to find a quiet and comfortable place with good light, and your dictionaries and other materials nearby.‎ Use your dictionary wisely. A common mistake of ESL students is to look up each unknown word in the texts they are given to read. __5__ It can even make understanding more difficult because by the time you reach the end of the paragraph, you have forgotten what you read at the beginning! So use your dictionary wisely.‎ A．Choose the right time to read.‎ B．Choose a right place to read.‎ C．Look at all these first before starting to read.‎ D．But it takes a long time and can be very boring.‎ E．The wider your vocabulary is, the easier you will find your reading.‎ F．Reading is also an excellent way to improve your general English.‎ G．The way you read a book or a text depends largely on your reasons for reading it.‎ 答案：1～5　FGCBD
