观看视频《海洋垃圾》片段，回答问题。
视频解说内容：日本“3*11”9级大地震引发强烈海啸，导致大量的房屋、汽车和各种残骸卷入太平洋，形成了一个长约111公里的“垃圾岛”。研究人员估计，这个漂浮在海上的“垃圾岛”两年内会漂至夏威夷，3年后漂到美国西岸。
其实，在日本地震和海啸导致大量垃圾卷入海洋之前，人们生活的这个星球中的海洋上就已经漂浮着大量的海上垃圾。2007年，美国科学家发现，太平洋上漂浮着一个巨大的“太平洋垃圾岛”，其面积有两个得克萨斯州那么大。虽然后来有人认为其面积被过分夸大了，但其存在却是不争的事实。
海洋垃圾不仅影响海洋景观，还可能威胁航行安全。但更可怕的是，会对海洋生态系统的健康产生致命的影响，进而对海洋经济产生负面效应。海洋垃圾已引起全球的高度重视，新加坡等发达国家正采取措施，尝试处理这一问题。
由于海上垃圾大部分是塑料，所以处理海上垃圾的首选办法是焚烧发电。不过海洋垃圾的焚烧发电有几个问题需要解决。除了打捞、运输、搁置脱水外，还会遇到二恶英的排放问题。由于塑料焚烧可产生大量的二恶英，会危及环境和生态，需要有特别能控制二恶英排放的高级焚化炉。
海洋垃圾的另一个处理办法是建造人工岛屿。1998年，新加坡政府在两个离岸的小岛实马高和西康之间建造了1公里长的岩石长堤，并分出了11个相互连接的海湾单元；将单元里的海水抽干，排放好一层厚厚的塑料膜；然后将垃圾灰烬倾倒在这些单元里进行密封，以防止泄漏。至于垃圾中那些不能燃烧和回收的材料，比如石棉，也被塑料密封并掩埋在泥土中。此后，每个月都要对单元周围的海水取样检测，到现在为止，还没有发现任何单元有泄漏和污染海水的情况。每当一个单元的垃圾填到二三米高时，就进行铺沙种草，接着继续埋置垃圾。如此反复，垃圾最高可埋置到30米。最后在上面栽种植物，不再堆放垃圾。

材料一 目前，我国垃圾堆存量已达60亿吨，占用耕地5亿平方米。全国660个主要城市中，有200个城市陷入垃圾包围之中。以城市人口6亿为例，如每人每年产生440公斤垃圾，年产生垃圾量为2.64亿吨。
材料二 英国的垃圾填埋率为90%，意大利为74%，美国为67%,法国为45%，德国为46%。 瑞士的垃圾焚烧率为74%，日本为72%，丹麦为70%。美国的废纸利用率为60%，铁罐头盒回收率为25%，玻璃回收率为20%。
（1)结合上下文，分别指出下列句子中划线部分的作用。（8分）
①到现在为止，还没有发现任何单元有泄漏和污染海水的情况。
②太平洋上漂浮着一个巨大的“太平洋垃圾岛”，其面积有两个得克萨斯州那么大。
(2)根据文章内容和链接材料，就垃圾问题进行探究，写出你的两点发现。（6分）
【要点】（1)①“到目前为止”，限制了时间，准确地说明了没有发现任何单元有泄漏和污染海水的现象只是现在的运行状况，并不表示以后一定不会发生。②（运用了作比较的说明方法），具体地介绍了“太平洋垃圾岛”面积之大，海上漂浮的垃圾之多，使读者对“太平洋垃圾岛”的印象更直观、更清晰。
(2) —是我国城市面临严重的生活垃圾问题，加强环保教育刻不容缓；二是海洋面临着人类生活垃圾危险；三是发达国家在处理垃圾问题方面有各自成熟的技术。

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.
