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. The seal is voluntary, but many organic producers use it.‎ 语篇解读：本文为一篇说明文。“有机食品”一词对我们来说耳熟能详。但有机食物和普通的食物在农业生产过程中到底有怎样的差异，并不是每一个人都很清楚。‎ ‎1．The main purpose of the passage is to ________.‎ A．promote the sales of organic foods B．inform people that organic foods are better for their health C．compare conventional and organic foods D．persuade people to become informed consumers 解析：选C　主旨大意题。该题目实际上是在考查文章是围绕什么内容展开的。文章的第一段就提出了conventional apple和organic ‎ apple的不同概念，下文就这两种事物进行了对比，故该文章的写作目的是告诉人们传统食品与有机食品的差别。‎ ‎2．According to the passage, organic farming is intended to ________.‎ A．improve the quality of the soil and water B．take the place of the traditional agriculture entirely C．prevent livestock from getting disease more effectively D．adopt environmentallyfriendly methods to grow plants and feed animals 解析：选D　细节理解题。文章表格中对有机农业和传统农业做法的对比体现了有机农业的优势：在对环境有益的基础上生产健康的食品。由此可知，有机农业旨在通过对环境有益的方法进行生产。‎ ‎3．Which of the following methods belongs to organic farming?‎ A．Using chemicals to kill insects and prevent disease.‎ B．Using rotted plants as fertilizers to promote plant growth.‎ C．Using growth hormones to speed up animals' growth.‎ D．Using pests to reduce insects and disease.‎ 解析：选B　细节理解题。根据表格右栏中的“Apply natural fertilizers to feed soil and plants.”可知B项正确。A项中的chemicals，C项中的hormones以及D项中的pests均不符合有机农业的要求。‎ ‎4．From the passage we know the organic certification program ________.‎ A．is not meant for produce of all producers B．makes it a must to attach a USDA Organic label C．sets restrictions on the sales of organic produce D．requires all foods to satisfy the strict government standards 解析：选A　细节理解题。根据最后一段可知，并非所有农产品的生产商都要给他们的产品进行有机认证。‎ Ⅱ.阅读七选五 How to be a better reader Reading‎ is an extremely important skill. 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
