狠批吧，我好久没写过作文了。。。。
综合 In the lecture, the professor makes several points about that the expansion of human population and the growth of agriculture not only  did  not impose bad effect on the habitats of birds, but also increase the areas suitable for some birds. While the reading states that wildlife in the united States, especially the birds ,have suffered from the mounting human population and the growth of the agriculture and the usage of chemical pesticide.
The first point that the professor uses to cast doubt on the reading is that even though the population of some species might decreased, some other animals' population did increased. According to the professor, in fact, the habitats for animals have increased  in the town and even the scarce hawk can been seen these years .However, the reading notes that traditional area continue to decrease due to the increase of the human population and settlements.
The second point that the professor challenges the reading is that further decrease of the natural habitats will not emerge in a short time. Also, new productive crops have been adopted in agriculture. On the contrary, the reading contends that more and more traditional areas will be converted to farming land thus, inevitable damage will impose on the birds .
Finally, the professor argues that new pesticides of less poisonous have been used and new kind of corps which are unattractive to pest or resist insects are being researched .In other words, Birds life will not be affected. This contradicts the point in the reading that eating poisoned insect or drinking contaminated water will affect the reproduction of the bird and even kill the birds.  
In short, the points asserted by the professor are different from what the reading says. The professor demonstrates that the size of the bird populations will not decreased.

As to whether the government and corporation should share all their scientific discoveries with other countries all over the world, my opinion and reasons are like this: the government and company can share part of their scientific discoveries, but not all. Since fierce competition could promote further development of science,the government and the company, generally, need the new discoveries to main their dominance in relevant field, they can not share everything with others.


No one could deny that fierce positive competition has made a huge contribute to making progress in human history. Fierce positive competition, however unlike negative competition, is a virtuous circle. When a country or a company makes breakthrough in scientific field and plays  dominant part in global, generally, the country or the company likely to keep exploiting in the relevant field and make greater progress. In order to keep pace with the premier country or company, other countries and companies, with no doubt, will spare no effort to innovating and finally make even huger progress, instead of just imitating. In the process of virtuous circle, obviously, constant humankind's giant leaps will be made.


In addition, relied on some remarkable scientific discoveries, government and company can dominate related field, even the world, and obtain great benefit. Here is an example from Steven Jobs, the legendary founder of Apple Inc, is best remembered for being an innovator in information technology field. The products from their company, like iPad, iPhone, is prevailing in global. Needless to say, noticeable profits have been brought to Apple Inc. by successive technology innovations. However, we can not neglect the fact that the huge profits and dominance are based on technology which are confidential. It's hard to image whether Apple Inc. can be so successful once the technology is shared by other companies.


In conclusion, government and corporation should not share all their scientific discoveries. Sharing everything with other countries will, undoubtedly, renders the government and the company lose their advantages and slow down human beings' pace in the journey of scientific exploration.
