Unit 5 Working the Land Using Language＆Assessing Your Progress Part 01 Listening In pairs, discuss what you can see in the photos and how you think each photo relates to world hunger. 3 What can you see in the photos? How does each photo relate to world hunger? The first photo represents the idea of drought. Either a river or a lake bed has been exposed by receding waters, leaving behind cracked soil. A child is pouring water onto the ground. When there is drought, crops cannot grow and animals may die. What can you see in the photos? How does each photo relate to world hunger? The second photo represents the idea of war. Hunger often comes with war, as often people cannot farm, or they cannot work to earn money to buy food. And, even if they had money to buy food, the markets might be empty or closed. What can you see in the photos? How does each photo relate to world hunger? The third photo represents famine. The child in the photo is a victim of famine, which is why his/her arm and hand are so thin. Famine is when the crops do not grow and there is not enough food for everyone to eat. While famine can be caused by drought, some of the worst famines in world history had other sources, such as insects or diseases that destroyed the crops, or weather that was either too hot or too cool for the crops to grow properly.

Listen to a radio interview and take notes. Then answer the following questions. 3. What does the FAO think about nutritious food? The FAO believes everyone should have the right to get healthy food. Listen to a radio interview and take notes. Then answer the following questions. 5. What does the FAO suggest countries do? Every county needs to focus on making new achievements in agriculture too, which can often benefit the whole world. Listen and identify how the speaker supports his facts. Match the supporting evidence with the facts. 1. According to our latest figures, … 2. There is strong evidence to suggest that … 3. Our research indicates that … A. wars can heavily affect food production and transportation. B. (world hunger) stands at around 11% of the world’s population. C. many people just can’t afford to eat well. Part 02 Reading Read for structure The problems with chemical farming What organic farming is Organic methods for producing rich soil Why man-made chemicals are still used in farming Read for details. adj. 分布广的 自20世纪中期以来，化学农药和人工化肥在农业中得到了广泛使用。当它们第一次被引进时，许多农民欢迎它们作为一种对抗作物病害和增加产量的好方法。然而，随着时间的推移，一些科学家发现，长期使用它们有时会损害土地和人们的健康。 主语从句，what是引导词 表语从句，其中that是引导词,在句中不作成分,没有词义。 Read for details. Why did many farmers welcome the introduction of chemical farming? It's a great way to fight crop disease. Read for details. For example, pesticides can damage the land by killing not only harmful bacteria and insects, but also helpful ones. In addition, these chemicals can stay in the soil and underground water sources for a long time. This affects the crops grown on the land and, in turn, the animals and humans who digest them. Many people worry that these chemicals may make them ill and even cause cancer. vt. 消化；吸收 例如，农药不仅可以杀死有害的细菌和昆虫，还可以杀死有益的昆虫，从而破坏土地。此外,这些化学物质可以在土壤和地下水源中长期存在。这影响了生长在土地上的作物，进而影响了消化它们的动物和人类。许多人担心这些化学物质会使他们生病甚至致癌。 过去分词短语作后置定语,表被动意义 定语从句，先行词是 the animals and humans，引导词是who Read for details. In fact, some pesticides like DDT have been prohibited in most countries because of the damage they cause to people and the environment. As for chemical fertilisers, crops grown with them usually grow too fast to be rich in nutrition. They may look beautiful on the outside, but inside there is usually more water than essential minerals, and they often have less flavour as well. n. 营养 adj. 基本的；必要的 n. 矿物质 事实上，像滴滴涕这样的杀虫剂在大多数国家已经被禁止了，因为它们对人类和环境造成了破坏。至于化肥，通常施了化肥的农作物生长得太快,无法提供丰富的营养。它们可能外表看起来很漂亮，但里面的水通常比必需的矿物质多，而且味道也不太好。 定语从句，先行词是damage，引导词是that或which Read for details. adj. 可供选择的 n. 杂货店 作为另一种选择，一些农民转向有机农业，许多顾客在当地杂货店购物时转向有机食品。有机农业就是不使用任何化学物质的简单农业。有机农场主注重通过自然的方式保持土壤的肥沃和免受病害。例如,许多有机农场主使用来自动物的天然粪便作为肥料。这使得他们地里的土壤矿物质更丰富。它还使空气、土壤、水和农作物不受化学物质的污染。 Read for details. Organic farmers also use many other methods to produce rich soil. They often change the kind of crop grown in each field every year. For instance, they may grow corn or wheat in a field one year, and then grow beans there the next. Why different crops are grown is because they put important minerals back into the ground, making it ready for the next batch of crops. n. 例子, 实例 有机农场主也使用许多其他方法来使土壤肥沃。他们经常每年改变每一块地的作物种类。例如，他们可能一年在一块地里种玉米或小麦，第二年在那里种豆子。种植不同的作物是因为它们把重要的矿物质释放回地里，让它再次为下一批作物做好准备。 主语从句,引导词是why,并且在主语从句中作状语 表语从句，引导词是because 现在分词短语，在句中作结果状语 Read for details. Organic farmers also plant diverse crops that use different depths of soil to help keep it rich. For example, peanuts grow on the ground’s surface, but many other vegetables put down deep roots. The goal of using different organic farming methods is to grow good food while avoiding damage to the environment or to people’s health. n. 深, 深度 n. 根；根源 有机农场主还种植多种作物，利用不同深度的土壤来帮助保持肥沃。例如，花生长在地面上，但许多其他蔬菜扎根很深。使用不同的有机耕作方法的目的是种植好的食物，同时避免对环境或人的健康造成损害。 定语从句，引导词是that，先行词是crops 句中 while doing 是省略结构，相当于 while 引导的时间状语从句 while it avoids.. Read for details. adv. 全部地 有些人宁愿完全停止在农业中使用人造化学品。阻止他们这样做的原因是化学农业满足了世界各地对粮食的巨大需求。有机农业远不能满足那样的需求。因此，要找到一个合适的解决方案,使人们的餐桌上有足够的食物，同时保持人们和环境尽可能地健康仍然有很长的路要走。 主语从句，引导词是what 同位语从句，对fact进行解释说明，引导词是that 定语从句，引导词是that它在定语从句中作主语，定语从句修饰前面的先行词solution。 Part 03 Writing 百度百科打算创建英文版的百度人物词条，请你结合以下信息，为袁隆平编写词条。 姓名:袁隆平 爱好:听音乐，游泳 职业:科学家 生活态度:生活简朴,淡泊名利 出生:1930 年,北京 毕业院校:西南农学院(现西南大学) 成就: (1)提高水稻产量,消除世界饥饿; (2)杂交水稻之父 注意: (1)词数80左右; (2)适当表达个人看法 参考词汇:西南农学院 Southwest Agricultural College; 杂交水稻之父 Father of Hybrid Rice 确定写作体裁主题 体裁 记叙文 主题 叙述袁隆平的事迹 确定时态和人称 第三人称 (Yuan Longping, he) 一般现在时(一般性的叙述)和一般过去时(袁隆平的过往) 写作思路 Key Words be devoted to, graduate from, ways to do, thanks to, Be honored as, live a...life, as for, as well as, make great contributions to, in one's eyes, more than Sentences 1. 袁隆平是一位致力于农业的伟大科学家。(be devoted to) Yuan Longping is a great scientist who is devoted to agriculture. 2. 袁于1930年在北京出生，毕业于西南农学院。(graduate from ) Born in Beijing in 1930, Yuan graduated from Southwest Agricultural College. 3. 毕业后,寻找种植更多稻米的方法是他的人生目标。(ways to do) After graduation, finding ways to grow more rice has been his life goal.
