Some questions about my English sentences.(2) This is a question of a spoken English test. Question:Do you prefer finishing your work once you got them as quickly as possible or to wait until the deadline, why? My answer: I like to do things earlier because I can have enough time for preparation, for example, it was last semester when we were asked to give a presentation in the class, it was important because it would be scored as a very important part of our final examination. But the professor assigned the instructions by emails, and I'm the president of our student union, so I receive hundreds of emails every day. So when I found out that I have to prepare a presentation, it was only less than two days before the deadline. Then I do nothing else but preparing my presentation all the day. It was a very challenging experience. After that, I do everything at the first time. Could you please help me to correct my sentences so it can looks more native?

Some questions about the setences. This is my answer to a toefl question. Question: Describe the problem your contry is facing now. My answer: Now the most severe problem in my country is the environmental problem. Although some of the environmental problem is a result of nature causes such as the volcano eruptions, but I believe that most is caused by human activities. The first kind of problem I would like to say is the air pollution. Now more and more people have their private cars, so the air pollution has become a major problem in China. And the second problem is the water pollution. This problem is caused by the industrialization of the city. If we don't take action now to prevent the contamination of water, the water would be too toxic for us to drink.

Do things earlier. Do you prefer finishing your work once you got them as quickly as possible or to wait until the deadline, why? I like to do things earlier because I can have enogh time for preperation, for example, it was last semester when we were asked to give a presentation in the class, it was important because it would be scored as a very important part of our final examination. but, the professor assign the instructions by emails, and I'm the president of our student union, so I receive hundreds of emails every day. and when I found out that I have to prepare a presentation, it was only less than two days before the deadline. then I do nothing else but preparing my presentation all the day. it was a very challenging experience.

I have some questions about my sentences. In such situation, taking action now is of more value because it saves the time that are unnecessarily wasted by our overthinkings. (I'm not sure with the word "overthinking", it seems that this is incorrect, I mean, thinking excessively, is there any better words? ) Buy it now, you get it. Consider for a moment, you miss it (I just want to express that if you buy it then you can get it, but if you think over for a long time, then you will miss the beautiful cloth. So, can I express my meanings in the way above? ) one must go through a large amount of information and look into every possible details of the consequence of decision (I use "go through" because I want to emphasize the largeness of the information. but I'm uncertain about it, maybe I made a mistake because I look it up in the dictionary and can not find the meaning I want. ) taking action now would save time for us to plan the future development and make a earlier start. ("plan the future development" seems not very native. is there any suitable expressions? )

First composition: Patience. I hope you can help me to correct some mistakes. Do you agree or disagree: Patience is usually not a good strategy. We should take action now rather than later. As modern society develops, an increasing number of people try their best to fulfill their life goal. At this time, the strategy used to success become a hot topic that has been widely discussed. Some believe that patience is a good strategy. Meanwhile, others who strongly opposite to it said that it will be more likely to be a successful man if we take action now rather than latter, in my opinion, the conclusion depends on the situations we are in and it is hard to say which is the better strategy. Admittedly, It is undeniable that patience is more favorable than in some specific situations than taking action now. Especially some cases that allow us to spend much time to think over, such as making a decision related to one's future development, or a huge investment for some critical projects. In these cases, every choice one made is vital to the future development. So any mistake would be critical. Only by thinking over the possible barriers, challenges, and future profits are we able to make a better choice and make less mistakes. And a large amount of time for consideration is indispensable because all of these to be considered require a careful evaluation. In this way, one must go through a large amount of information and look into every possible details of the consequence of decision, which is considerably time-consuming. And only patience can offer us with enough time to think over and make a better choice. Patience also makes us thinking rationally so that we can make a choice from further perspective rather than simply choose the better one regardless of the future development. However, in other cases such as the circumstances with little time for considering, taking action right now is also necessary and desirable. Many opportunities are transitory like a temporary tides, which we take it and then loss it nearly in the same breath. For example, you are looking for a beautiful clothes for your friend's party. Now you see one that seems considerably suitable for you. Buy it now, you get it. Consider for a moment, you miss it--if you turn to the next store to see if there will be a better one, the original one might be brought away by others as you return. In such case, taking action now is no doubt the better choice. Besides, taking action now would save time for us to plan the future development and make a earlier start. In other cas
