Unlike conventional farming, which relies heavily on chemical fertilizers and pesticides, organic farming uses natural methods such as crop rotation, composting, and biological pest control to grow crops. However, organic farming also faces significant challenges. One major issue is lower crop yields compared to conventional farming. Studies show that organic farms typically produce 10 to 20 percent less food than conventional farms. This is partly because organic farmers cannot use synthetic fertilizers to boost growth quickly, and partly because pests and weeds can cause more damage without chemical pesticides. Another challenge is the higher cost of organic food. Because organic farming requires more labor and has lower yields, organic products often cost 20 to 100 percent more than conventional products. This makes organic food less accessible to low-income families, who may not be able to afford the higher prices. Despite these challenges, many experts believe that organic farming has an important role to play in the future of agriculture. They argue that a combination of organic and conventional methods, known as "integrated farming," may be the best approach. This way, farmers can reduce chemical use while still maintaining high enough yields to feed the growing population. 1. What is the main difference between organic farming and conventional farming? A. Organic farming produces more food than conventional farming. B. Organic farming uses natural methods while conventional farming uses chemicals. C. Organic farming is more popular than conventional farming worldwide. D. Organic farming costs less than conventional farming. 2. According to the passage, what is one major challenge of organic farming? A. It requires more land than conventional farming. B. It uses too much water compared to conventional farming. C. It produces less food than conventional farming. D. It is more difficult to learn than conventional farming. 3. Why is organic food often more expensive? A. Because organic farmers want to make more money. B. Because organic farming requires more labor and has lower yields. C. Because organic food is transported over longer distances. D. Because organic farming uses more expensive equipment. 4. What solution do many experts suggest for the future of agriculture? A. Completely replacing conventional farming with organic farming. B. Continuing to use only conventional farming methods. C. Combining organic and conventional methods in integrated farming. D. Developing completely new farming methods unrelated to either. 任务二：语法填空 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Food waste is a global problem that has serious economic, environmental, and social consequences. According to the Food and Agriculture Organization, approximately one-third of all food 1.____________ (produce) for human consumption is wasted every year.

The farm, which is devoted to growing pollution-free vegetables and fruits, has become a popular destination for school trips in our city. The farm is comprised of three sections: a vegetable garden, a fruit orchard, and a greenhouse. We spent the morning picking fresh strawberries and tomatoes in the greenhouse, and the afternoon learning about crop rotation and natural pest control from the farm manager. He explained how they avoid chemical fertilizers by using compost and beneficial insects. What this activity has given me is not only the pleasure of picking fresh fruit, but also a deeper understanding of where our food comes from. It has raised my awareness of the hard work behind every meal and the importance of supporting sustainable agriculture. 【读后续写】环境描写——乡村/农场场景 环境描写素材： 1. 日出与田野： The sun began to rise in the sky, bathing the whole village in golden light. 太阳开始从空中升起，整座村庄沐浴在金色的光中。 The morning mist lifted slowly, revealing the endless green fields stretching to the horizon. 晨雾慢慢散去，一望无际的绿色田野延伸到天边。 2. 风雨与土地： The dark clouds gathered and heavy showers poured down upon the parched earth. 乌云聚集，倾盆大雨落在焦干的大地上。 Wind and rain swept across the fields, tearing the dark and gloomy sky apart. 风雨席卷着田野，灰暗沉郁的天空被撕裂得七零八落。 3. 丰收与喜悦： The golden rice fields waved in the breeze, and the air was filled with the sweet smell of ripening fruit. 金色的稻田在微风中起伏，空气中弥漫着成熟水果的甜香。 4. 夜晚与宁静： The roaring wind gradually calmed down, and the village fell into a peaceful silence. 咆哮的风渐渐平静下来，村庄陷入了一片宁静。 环境描写填空练习： The morning was cool and fresh when we arrived at the farm. 1.________________________（晨雾慢慢散去）, revealing the endless green fields stretching to the horizon. 2.________________________（金色的稻田在微风中起伏）, and the air was filled with the sweet smell of ripening fruit.
