First of all, thank you very much, Prof. Liu, for the opportunity you give us. It is a very great pleasure indeed for us to make a conference report on the stage.
My name is Jeremy, Chinese name Hebiao, a master student from School of Mechanical Engineering, and our team has five people, two and me in the same academy, the other from School of Transportation. Today, our presentation is “Global Warming”.
We will make this presentation from the following aspects. OK, let us take a journey. Venice is a beautiful water city, Venice looks like a dolphin. Maldives, an island country in the Indian Ocean, is famous for its tourism industry. Some beautiful pictures……………………..However, both of the two islands will be covered by water if the global warming continue working or worse after half an century. So, if you want to make a close touch with them, please catch time.
Next, my workmates will show some information detailed.
Before I explain the term of “Global Warming”, I want to share some pictures to everyone.
Right, let's get started. Please direct your attention to the screen.As you can see from a set
of photos of “NASA”, during the past century, the Land-Ocean temperature has risen 0.8 degree Celsius，and the sea level has risen 7 inches.
More seriously, the index will continue to rise faster. According to the index of global governance, the average global temperature will be 3.5 degree Celsius above normal by the end of the century.
In a report, scientists working for the United Nations concluded that sea levels could rise by 8 to 23 inches by the end of this century.
To return to the main subject, Global warming is defined as the rise of the average temperature of the Earth's near-surface layer of air as well as the oceans, and extends to the projected continuation of that rise.
Now, let's switch to the next photo of” CO2 emissions”which from carbon dioxide Information Analysis Center.
As can be seen by the figure, Carbon dioxide emissions increase year by year from the middle of the last century. The current Carbon Dioxide emission is four times than the emissions fifty years ago.
What is the connection of global warming and carbon dioxide? Carbon dioxide is a
'greenhouse gas ', a form of air pollution which causes global warming.
Global warming is the increase in the average temperature of the Earth's near-surface air an d oceans in recent decades and its projected continuation.The reason about global warming are as follows:
1.The forest resources in factors
Around the world, because of natural or man-made factors causing forest area is greatly red uced
2.Acid rain harm factors
The effects of acid rain to the ecological environment have become more and more attention all over the world. Acid rain can destroy forest, acidification lakes, endanger biological, etc. At p resent, the acid rain in the world more concentrated in Europe and North America, most of the ac id rain occurred in developed countries,some developing countries, acid rain, also in theoccurren ce and development rapidly.
3.Toxic waste pollution factors
Growing toxic chemicals not only pose a serious threat to human survival, but also to the ecolo gical environment of the earth's surface will lead to harm.
4.Water pollution factors
According to the global environment monitoring system for water quality monitoring project shows that about 10% of the global monitoring of the pollution of the river, since this century, the hu man water consumption is dramatically increased, at the same time, water pollution, scale is continuall y expanding.
5.Human activities
Since the industrial revolution, human activities widely changed the shape of the earth's surf ace and the distribution of plants and animals, especially the extensive use of fossil fuels and other ways to discharge a large amount of greenhouse gases into the atmosphere.
Thanks for listening,this is all for my presentation.
As we all know, global warming means not only the temperature of all parts of the world to increase, but harm human’s life as well. There are many aspects of influence.
Initially, natural disasters happen more frequent. The maximum wind speeds of the strongest tropical cyclones have increased significantly since 1981, according to research published in Nature this week. And the upward trend, thought to be driven by rising ocean temperatures, is unlikely to stop at any time soon.
Furthermore, Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East of the US. However, many nations around the world will experience the effects of rising sea, which could displace millions of people.
Additionally, according to research published in Nature, by 2050, rising temperatures could lead to the extinction of more than a million species. Let’s talk about the dangers of global warming in the polar region. Resident animals like polar-bear and penguin will lose their habitats; these small populations are highly vulnerable to extinction. For some species, the fragmented habitats become too small to support a sustainable population.
Finally, global warming also caused massive crop failures. “Climate change is expected to have the most severe impact on water supplies” , “Shortages in future are likely to threaten food production, reduce sanitation, hinder economic development and damage ecosystems. It causes more violent swings bet ween floods and droughts.” And so on.
What can we do to prevent the situation from deterioration?
So as my teammates said there are lots of dangers about the global warming and the greenhouse effect, what should we do to face these problems?
For the government, I think our society should introduce some policies to limit many inappropriate behaviors which will cause the global warming easily. We should be encouraged to take the public transports, instead driving outside, such as taking the bus, metro or BRT when you go out. Clean energy is also a good choice in our daily life, such as the wind energy, hydroelectric energy, instead of the thermal power using fossil fuel or gas from the nature, for these fuels causing lots of carbon dioxide after burning, and this is the crime culprit which causes the global warming.
For us, we can do a lot to protect the earth. Closing the light after using, which is the easiest thing we can do to slow down the global warming and the greenhouse effect. By using Air-conditioning in a high frequency will also accelerate the process of the global warming. So we can heighten the temperature when we using it , furthermore the best way is not using it. Remember to save all the things when we use them. Only in these ways, can we have a good effect when we fight for the slowing global warming.
That’s all our presentation, thanks for watching and listening.

Today i want to introduce you a film named___WALL-E. The story happened in a distant, but not so unrealistic future, where mankind has abandoned earth because it has become covered with trash from products sold by the powerful multi-national Buy N Large corporation. WALL-E, a garbage collecting robot has been left to clean up the mess. Mesmerized with trinkets of earth's history and show tunes, (2 WALL-E is alone on Earth except for a sprightly pet cockroach. One day, Eve, a sleek (and dangerous re-connaissance robot, is sent to earth to find proof that life is once again sustainable. WALL-E falls in love with Eve. WALL-E rescues Eve from a dust storm and shows her a living plant he found amongst the rubble. Consistent with her "directive" Eve takes the plant and automatically enters a deactivated state except for a blinking green beacon. WALL-E, doesn't understand what has happened to his new friend, but true to his love, he protects her from wind, rain, and lightening, even as she is unresponsive. One day a massive ship comes to reclaim Eve, but WALL-E, out of love or loneliness hitches a ride on the outside of the ship to rescue Eve. The ship arrives back at a large space cruise ship, which is carrying all of the humans who evacuated earth 700 years earlier. The people of earth ride around this space resort on hovering chairs which give them a constant feed of TV and video chatting. They drink all of their meals through a straw out of laziness and/or bone loss, and are all so fat that they can barely move. When the auto-pilot computer , acting on hastily given instructions sent many centuries before, tries to prevent the people of earth from returning, by stealing the plant, WALL-E, Eve, the portly captain, and a band of broken robots stage a mutiny.

It’s my pleasure to introduce my hometown，especially as the first to eat crab [kr?b]. Have you ever heard of the tower [?tau?]? Yes, it’s Yellow Crane [krein] Tower . (Chinese: 黄鹤楼). It is a famous and historic [his?t?rik] tower, and built in the year 223 AD. The tower is the landmark in Hubei province [?pr?vins]. Yes, I come from Hubei. At first, I will give an overview [???v??vju:] of Hubei. Hubei province, with a population of 60 million, is located [l???ke?t?d] in the middle reaches of the Yangtze river, and to the north of dongting lake, with Wuhan as the provincial [pr??v?n??l] capital[ ?k?pitl], and Qichun as my birthplace.

One of the effects of global warming is the destruction of many important ecosystems.Changing and erratic climate conditions will put our ecosystems to the test, the increase in carbon dioxide will increase the problem. The evidence is clear that global warming and climate change affects physical and biological systems. There will be effects to land, water, and life. Already today, scientists are seeing the effects of global warming on coral reefs, many have been bleached and have died. This is due to warmer ocean waters, and to the fact that some species of plants and animals are simply migrating to better suited geographical regions where water temperatures are more suitable. Melting ice sheets are also making some animals migrate to better regions. This effects the ecosystems in which these plants and animals live. Several climate models have been made and they predict more floods (big floods), drought, wildfires, ocean acidification, and the eventual collapse of many ecosystems throughout the world both on land and at sea. There have been forecasts of things like famine, war, and social unrest, in our days ahead. These are the types of effects global warming could have on our planet. Another important effect that global warming will bring is the loss and endangerment of many species. Did you know that 30 percent of all plant and animal species alive in the world today are at risk of extinction by the year 2050 if average temperatures rise more than 2 to 11.5 degrees Fahrenheit. These mass extinctions will be due to a loss of habitat through desertification, deforestation, and ocean warming. Many plants and animals will also be affected by the inability to adapt to our climate warming.

Teaching Plan Contents: Reading Book 6 Unit 4 Global warming I.Analysis of the Teaching Material This article is from a magazine about global warming, which illustrates how global warming has come about and different attitudes to its effects. The passage is long, abstract and far away from their life. What’s more, there are many mouthful professional terms, which increases students’ difficulty while reading, although they have some knowledge about global warming. II. Analysis of the Students Students from Senior Two are the students in an excellent level, who have good abilities to read and speak. This unit talks about global warming, which has been taught in Geography. It will help students understand the text better and I believe the students will be interested in this class. However,because they pay little attention to this topic in the daily life, they may have few desire to speak something about global warming. III. Teaching objectives 1. Knowledge objective 1) Enable the students to analyze how global warming has come about； 2) Get students know different attitudes towards global warming and its effects. 2. Competence objective Improve the students’ reading and speaking abilities. 3. Emotion objective 1) Develop student s’ teamwork. 2) Raise their awareness of global warming. IV. Important points Enable the students to understand how global warming has come about. V. D ifficult points Get the students understand how global warming has come about. Let the students understand the difficult sentences better. ①It is human activity that has caused this global warming rather than a random but natural phenomenon. (Line 6) ②All scientists subscribe to the view that the increase in the earth’s temperature is due t o the burning of fossil fuels like coal, natural gas and oil to produce energy. (Line 18) ③This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth.(Line 26-29) VI. Teaching aids: Multimedia classroom, printed material VII. Teaching methods: Task-based teaching, communicative teaching method VIII.Teaching procedures: Step 1. Lead in and pre-reading (5 mins ) It’s reported that global temperatures continue to rise, making July 2016 the hottest month in the history of the earth. Did you feel extremely hot in July?
