【参考例文】

Hello, everyone,

Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

Then what should we do to deal with the problem? On one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.

As for me, I will call on the people around me to live thriftily. And for the moment, I think, we should study hard to develop science and help solve the food shortage in the future.

What Lessons Should Be Learned From the Drought

The drought in the south-west China has lasts for several months, which makes people face water and food scarcity. We should learn lessons from it.

The drought can be cause by several factors. Firstly, about 63 percent of cities in China are facing water scarcity. The situation is worsened by pollution and industrialization. In addition, too many trees have been cut down, so forest coverage has been decreasing rapidly. What's more, some water conservation projects haven't been functioning properly, thus people there have had to rely more heavily on rainfall for their water supply. Most of China's irrigation systems are very old.

In order to prevent this case coming about again, we should improve our awareness of saving water, making proper use of water and recycling water. Meanwhile, we ought to plant more trees and protect environment to prevent loss of water and soil erosion. Of course, the governments should increase investment and repair water conservation projects as timely as possible.
