请为幼儿园大班设计一份“环境保护”的教育主题活动设计。
社会活动：垃圾“回家”(大班) 活动目标：
1．帮助幼儿了解垃圾的来源，认识其危害，并能区分可回收、不可回收及有害垃圾。
2．养成不乱丢垃圾的好习惯，建立初步的环保意识。
3．引导幼儿愿意为维护环境卫生做一些力所能及的事。
活动准备：
1．知识经验准备：请幼儿观察居住小区及周围的环境，和父母一起讨论收集有关生活中垃圾的相关图片。
2．物质准备：事先收集一些废旧材料，如可乐瓶、果奶瓶、玻璃瓶、纸盒、废电池、废纸等；两段录像短片(整洁和脏乱小区的环境录像、垃圾分类回收和处理的科技短片)。
活动过程：
第一环节：了解垃圾的来源
播放录像(录像内容：整洁美丽的小区，又脏又乱、蚊蝇飞舞的小区景象)，提问：“你们喜欢哪个小区，为什么?”“垃圾从哪里来?”“垃圾有什么危害?”
让幼儿了解满地的垃圾是因为人们不讲卫生，随意丢弃杂物而造成的。肮脏的环境给人们的健康带来许多危害，使幼儿产生送垃圾“回家”的愿望。
第二环节：了解垃圾的分类及处理
播放科教短片：垃圾的分类和处理。提问：“垃圾可以分成几类?”“哪些垃圾可以重新回收?”“我们该怎么做?”通过短片让幼儿了解垃圾的种类及不同的处理方法，知道有些垃圾可以回收，有些垃圾有害，对我们的生存环境有影响，从而产生分类丢垃圾的意识。
第三环节：送垃圾“回家”
幼儿亲身尝试，将实物垃圾送到环保垃圾简内。提问：“你们认识这个垃圾筒吗?可回收垃圾筒是什么颜色的?
不可回收垃圾筒是什么颜色的?有害垃圾筒又是什么颜色的?你们能将这些垃圾送回它们的‘家’吗?”
认识环保垃圾筒，了解绿色代表可回收垃圾，黄色代表不可回收垃圾，红色代表有害垃圾。在送垃圾“回家”的游戏中，能正确分类投放，帮助幼儿树立环保从我做起的意识。
第四环节：设计“环保标志”。幼儿结合自身说说我们该如何保护环境，引出设计“环保标志”。提问：“保护我们的生存环境，我们该做些什么?”
鼓励幼儿为环保活动做力所能及的事，争做“小小环保宣传员”。设计“环保警示标志”，张贴“我们只有一个地球”等宣传画。
活动延伸：
收集废旧材料，投放在活动区中。

语言素材：
Alone in Antarctica
At 50 I was the first woman to travel alone to the North Pole. But what should I do to celebrate my 60th birthday? What else, but a journey at the opposite end of the world, Antarctica. I began my almost 400-mile journey on November 1st, 1997. I walked and skied alone. My dog team were not with me to pull my sled. Another journey of challenge and danger was about to begin.
The first days the weather was very good. The wind was icy but not very strong and there was bright sunshine 24 hours a day. But changes were just around the comer. On the third day I was struggling through stormy weather and during the next week the wind grew stronger and I found myself spending a whole day in my tent.
I had travelled only two hours one day when the winds increased so much that I had to put my tent up before the winds became too strong. Within a few minutes the winds increased to a howling storm that threatened to blow me and my tent away, but none of that happened.
On November 12th the storm died down. It was my birthday and I wanted to make that day special. I thawed a frozen cake over my fire, placed a candle on the top, lit it and sang "happy birthday" to me, at the top of my voice.
A few days later, I was moving forward over a slope that seemed safe when suddenly without warning my worht dropped out from under my skis. I had fallen into a hole and was hanging on the ropes tied to the sled. A piece of ice fell down and I never heard it land. The bottom was a few hundred feet below. I used to practice self rescue many times in the mountains where I live and carefully began climbing out. It took a long time but I finally got out. I was thankful for all the training I had had.
I was in good health and all of my equipment was working well. I was so optimistic that I decided that the next day, the 22nd day of. the expedition, I would increase my workday to 12 hours.
The next morning I had a bad accident with the sled and hurt my leg. I couldn't stand on my left leg and my head was woozy from hitting the ground. But I knew that I had to get up. Lying on the ice, I would soon die. I struggled to my knees knowing that somehow i had to put my tent up for shelter. On hands and knees I got the tent up and dragged my sleeping bag into the tent and lay down out of the cold wind.
I had to make a decision. Wait to get better or give up? I had to think of my family, which is very important to me, and do the right thing. I did so without regret. I had met the challenges of solo travel in an extreme climate. It is an experience I shall never forget and shall value for the rest of my life.

Passage 2
In Brazil, the debate over genetically modified organisms, or GMOs, affects mostly soybean production. Brazil is the world's second largest producer of soybeans behind the United States and ahead of Argentina. Most European and Asian retailers want to remain GM free.
Non-governmental organizations (NGOs) in Brazil are going on a media offensive to prevent the legalization of genetically modified crops. Environmentalists and consumer groups for years have been able to thwart government and companies' attempts to legalize altered food. In radio dramas that are being broadcast in remote regions, Brazilian NGOs are telling soy farmers the use of genetically modified seeds could endanger their health, their fields and their business. "We are not saying that genetic engineering is, in principle, something bad; we say that we need more science to be sure that it will work in an appropriate way with no harm in the future," said campaign coordinator Jean-Marc von der Weld. "This is both for health and environmental reasons. The other question is on economics. What we think is that in Brazil, if we approve the GMOs, we will lose a spectacular advantage that we have now. We are selling more to the international market, mostly for Europe and Asia, than we have done in our history, because we are not GMO contaminated."
Another opposition group, ActionAid, has been organizing grass-roots support in Brazilian farming regions to rouse consumer sentiment against legalization. ActionAid public policy director Adriano Campolina says he is fighting for farmers to remain independent."When the small-scale farmer or a big farmer starts using this kind of seed, this farmer will be completely dependent on the transnationals, which control intellectual property fights over these seeds," he said.
Brazilian scientist Crodowaldo Pavan said there should be checks on what multinationals can do, but that doesn't mean GM seeds should be banned. He says fears over their usage are unfounded. Despite the official ban, Dr. Pavan says up to one third of Brazil's soy crop is genetically modified, because GM seed is being smuggled from Argentina. Brazil's government has invested heavily in a GM project by the U.S. biotech company, Monsanto, but the project was put on ice following a successful court challenge by consumers.
What does the Brazilian scientist Crodowaldo Pavan say about genetically modified products?

The anti-GMO groups are hoping the politicians' preoccupation with the October presidential
election will give them time to gather enough support to defeat any future attempts to legalize genetically altered crops.

Passage 1
Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision.
In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed.
Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.
Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with sharp difference. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities,becauseof thesharpdifferencein appearance between them and their white counterparts.
