1. 完成文本主要信息填空（斜体字部分设空）：As a witness to farmers’ poor harvests and even a severe shortage of food, Yuan Longping was determined to devote his life to tackling this crisis. After graduation, he realized that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieve higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through trial and error, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China was comprised of crops generated from Yuan’s hybrid strains. His innovation has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of leisure and unconcerned about celebrity or fortune, Yuan continues to turn one vision after another into realities.2. 模仿写作：Do some research via the Internet and introduce another agricultural scientist, Chen Risheng（陈日胜）, using the structure, expressions and writing techniques you have learnt from the text “A Pioneer for All People”.【设计意图】任务1是对文本内容和词汇学习成效的检测。任务2借助文本中学到的词汇和写作手法仿写另一位科学家，提升学生迁移运用词汇、文体结构和写作方法的能力。

司汤达是善于从爱情中反映重大社会问题的文学大师。于连的两次爱情都与时代风云紧密相连，这是当时阶级角逐的一种表现形式，他对德·雷纳尔夫人后来的确也产生了真正的感情，但开始是出于小市民对权贵的报复心理。因此，于连第一次占有德·雷纳尔夫人的手的时候，他感到的并不是爱情的幸福，而是拿破仑式的野心的胜利，是"狂欢"和"喜悦"，是报复心理的满足。 如果说于连对德·雷纳尔夫人的追求还有某些真挚情感的话，那么于连对玛蒂尔德小姐的爱情则纯属政治上的角逐，玛蒂尔德既有贵族少女的傲慢，任性的气质，又受到法国_的深刻影响。她认为，如果再有一次_，主宰社会的必定是像于连这样富于朝气的平民青年。同于连结成伉俪，既富于浪漫气息，又找到了有力的靠山。而于连则认为与玛蒂尔德小姐结婚可以爬上高位，青云直上，因此不惜去骗取她的爱情。
人教版高中地理选修2中、低产田治理的地理背景教案
（1）黄淮海平原后备耕地不足，现有耕地面积不可能增加很多，因此提高农作物产量的着眼点应该是挖掘现有耕地的生产潜力。（2）黄淮海平原现有耕地中大部分存在着不同程度的限制性因素，对这些土地的整治是黄淮海平原发展农业，尤其是种植业的关键所在。[经典例题1]下列关于黄淮海平原的叙述，正确的是A、夏秋多雨，地势低平，易发生旱涝、盐碱B、从东向西，盐碱化程度越来越严重C、土地限制性因素面积占土地总比重最大的是干旱缺水土地D、黄淮海平原西部地区中、低产田分布较集中解析：黄淮海平原秋季降水少。从东向西，黄淮海平原地势渐高，盐碱化程度应渐轻。黄淮海平原西部地区，耕地质量较高，能够比较充分地满足农作物生长发育的需要，是黄淮海平原粮棉稳产高产区，故D选项是错误的。解答本题常见的错误是认为A选项是正确的，只要分析一下黄淮海平原秋季是否多雨就可以排除思维障碍：在正常年份，因受夏季风影响，7、8月锋面雨带控制黄淮海平原，带来大量的降水；秋季，锋面雨带对黄淮海平原影响较小，故降水也小。

This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

The grammatical structure of this unit is predicative clause. Like object clause and subject clause, predicative clause is one of Nominal Clauses. The leading words of predicative clauses are that, what, how, what, where, as if, because, etc.The design of teaching activities aims to guide students to perceive the structural features of predicative clauses and think about their ideographic functions. Beyond that, students should be guided to use this grammar in the context apporpriately and flexibly.1. Enable the Ss to master the usage of the predicative clauses in this unit.2. Enable the Ss to use the predicative patterns flexibly.3. Train the Ss to apply some skills by doing the relevant exercises.1.Guide students to perceive the structural features of predicative clauses and think about their ideographic functions.2.Strengthen students' ability of using predicative clauses in context, but also cultivate their ability of text analysis and logical reasoning competence.Step1: Underline all the examples in the reading passage, where noun clauses are used as the predicative. Then state their meaning and functions.1) One theory was that bad air caused the disease.2) Another theory was that cholera was caused by an infection from germs in food or water.3) The truth was that the water from the Broad Street had been infected by waste.Sum up the rules of grammar:1. 以上黑体部分在句中作表语。2. 句1、2、3中的that在从句中不作成分，只起连接作用。 Step2: Review the basic components of predicative clauses1.Definition

Step 5： After learning the text, discuss with your peers about the following questions:1.John Snow believed Idea 2 was right. How did he finally prove it?2. Do you think John Snow would have solved this problem without the map?3. Cholera is a 19th century disease. What disease do you think is similar to cholera today?SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.keys:1. John Snow finally proved his idea because he found an outbreak that was clearly related to cholera, collected information and was able to tie cases outside the area to the polluted water.2.

He identified those houses that had had no deaths and surveyed their drinking habits. The evidence clearly pointed to the polluted water being the cause.3. SARS and Covid-19 because they are both deadly and fatally infectious, have an unknown cause and need serious public health care to solve them urgently.Step 6: Consolidate what you have learned by filling in the blanks:John Snow was a well-known _1___ in London in the _2__ century.
