The environmental issues are attracting more and more concerns recently. More and more pollutants are released to our enviroment without detoxication. The recent university graduates should make some contributions to lessen this problem.
For example, the environmental engineering graduates may devote themselves to devolop some new and efficient ways to monitor air pollutants. Chemical engineers, may concentrate on optimize the chemical processes, in order to minimize pollutants generated. Moreover, electric engineers could develop some good ways to produce electric power in a very large scale, which can be used to replace the traditional energy source, such as oil and coal.
Not only the engineers, politicians also play a very important role in improving our environment. They can accept the experts' advice and make some policies to improve the environment.
All in all, experts from different fields should cooperate to come up with some good ways to create a better environment.

my commom grammer mistakes
Here is the summary about the two grammar mistakes I always make in writing an essay.
First of all, I do not pay enough attention to word forms when I write an essay. For example, 'I should have told him the truth.' indicates that I did not tell him the truth. But sometimes, I used a negative sentence to express this meaning, 'I should not have told him the truth.', which is not correct. Not only the tense of a verb matters, the plural or single form of the word also makes a big difference. For instance, 'wood' means that kind of material; on the contrary, 'woods' means forests. The meaning of the word changes dramatically just by inserting a letter 's'. Moreover, we need to use a noun form rather than a verb form after some verb infinitive. What follows 'look forward to', for example, should be 'seeing' instead of 'see'.
Secondly, I often make a mistake on using parellel structure. The sentense structure will become very confusing if we use several unparellel phrases simutaneously. For example, 'this natural disaster is caused by unaccurate weather prediction and the officials did not take actions in time. Rather, we should change 'the officials did not take actions in time' to 'slow official actions'. Alternatively, the whole sentence could be changed to 'this natural disaster is caused by the facts that the weather prediction was not accurate and the offiicials did not take actions in time'. Both the two ways has successfully avert the problem of confusion.
To sum up, I need to fucus on the word forms and parellel sentence structure in writing essays.

discussion on green chemistry
The topic of our discussion is whether Singapore should promote development of green chemistry. Both the proponents side and the opponents side believe that green chemistry is a good measure to facilitate sustainable development. The proponents argue that it is very beneficial to development green chemistry in Singapore, by giving some evidence to prove that Singapore has enough manpower, advanced technology and economic basis to develop green chemistry. On the other hand, the opponents claim that the harms of developing green chemistry overweigh its benefits.
The proponents think manpower in Singapore is sufficient to develop green chemistry. Every year, Junior colleges cultivate thousands of outstanding students; NUS, NTU, and SMU recruit lots of students; MOE introduces abundant professors from various famous universities and research agencies. However, the opponents argue that Singapore lacks manpower since a large amount of Singaporeans go abroad for further education after graduation from junior colleges, most of which will not pursue their careers in Singapore afterwards.
Moreover, in the proponents' opinion, Singapore has an advanced technology in green chemistry. The Agency for Science, Technology and Research (A*Star) plays a leading role in this area. One of the major topics in A*Star is green chemistry and the development is encouraging. Nevertheless, the opponents advocate that since green chemistry is a complex technology, Singapore cannot finish this task independently.
Last but not least, green chemistry is economically applicable in Singapore, as far as the proponents are concerned. The GDP of Singapore in 2008 is 257,418.5 million, ranking at the top 50 in the world. Singapore’s strong economic power lays the foundation of the development of green chemistry. Whereas, the opponents believe that it is not an appropriate time to promote green chemistry. They reiterate that applying green chemistry technology, which is too costly, may paralyze the whole economic system in Singapore at this stage when the whole world is in financial crisis.
All in all, both sides show sufficient evidence to support their arguments. The main concern is still if Singapore possesses mature prerequisites to develop green chemistry, not only its manpower and technology, but also its economic power.
