【正文】 more places, I think, should be planned for wild animals in 21st contrary. Thus, it is obviously noticed that more trees are planted and more wildlife conservation areas are planned, ensuring that wild animals will be under protection. As we can see from the improvement, in the 21st contrary, wild animals would be leading a happy life. To sum up, we cannot live without wild animals due to their profound effects on us. For this reason, we should try our best to protect them. Let’s remember one thing—protecting wild animals is equivalent to protecting ourselves. Wild animals have no place in the 21st contrary, and the protection for them is a waste of resource. To what extent, do you agree or disagree with the above statement? Biological diversity has never been as threatened as it is today as a result of the process of human civilization. The various forms of pressure created by human activity have destroyed natural balance, led to the deterioration of natural habitats, geic erosion and the rarity, even disappearance, of a number of plant and animal species. As the pace of civilization accelerates, more people, taking more space, needing to use more natural resources, engaging in evergrowing consumption, impose sever deterioration on the habitat of animals. An increasing number of people e to realize that the disappearance of animals will result in serious threat to the equilibrium of ecosystem. Simply put, the extinction of hawks, rateating bird seen in many regions, will result in the rapid propagation of rats. And rats, further, will destroy the prairies and threaten the other animals like gazelles, zebras, and others, who live on grass and green lands. The coexistence of animals and human beings creates perfect harmony and brings about vividness to our pla. It is hard to imagine what our world would be like without animals. Sociologists also point our that the disappearance of animals can cause social and economic problems. Animals trade, as a supporting sector to the world economy, was very active before. However, the situation is beyond control since animals trade is very profitable and alluring. Many species cannot escape the adversity of being killed. Certainly, our diet cannot be without meat. There are living stocks, which can provide us with sufficient and nutritious produce. Therefore, we need not to resort to wild animals, especially the endangered ones. To protect animals is to protect our living environment. Every individual should join efforts to keep the diversity of animals. 措施類解決方案： The gap of living in cities and the countryside is larger and larger. What are the reasons in your country and how to reduce the differences? As the step of economic development accelerates, the gap between the city and the countryside bees more and more overt, which arouses colossal concerns. Take a further look at the phenomenon, there are three major causes. Firstly, the insufficiency of investment in the rural areas accounts mainly for the issue. China, for example, covers a very large area. Due to the emphasis on the development in the coastal areas, the government devotes more investment in the large cities, such as shanghai, Beijing and Guangzhou. The investment, undoubtedly, is repaid by the threefold increase of economy and merce in these cities. However, this is not the case in the rural area and the western regions. The lack of investment barriers the productivity and economic development and sharpens the gap between the city and the countryside. Secondly, the low education level in the rural areas contributes partly to the gap of living. Education is the prime force of productivity. Keeping this in mind, many countries and governments give priority to the development of education. China’s education witnessed a rapid growth in the past decade. However, the education level in the countryside still keeps very low. The enrollment of primary schools and secondary schools is much lower pared with the advanced regions, not to mention the developed countries in the world. Without good education, the development of economy and technology would be dream difficult to be realized. Finally, the influx of migrant workers to the cities form the countryside deteriorates the undeveloped conditions in the rural areas. The life style in the urban areas is very attractive to the people in the countryside. To seek more working opportunities, many people abandon the fertile lands and leave them uncultivated. If the situation continues, it will lead to serious unbala
