presentation

for me i like to do the presentation because there is not too much chance that others all listen to what you said, it is a feeling of become the center of the world. and i think that is why i feel confident when i do the presentation. in the past i did not have these chance a lot. i am iappreciate these experiences after the presentation when i recollect is i can find out many mistake in the presentation include grammar mistake and pronunciation mistake. but when i talking i did not feel it any more. may be it is a habit but i am trying to correct more mistake in the next time.
for the presentation i have a habit i dont know it is good or bad. which is i dont want practice more and 2 to 3 times maximum because i dont want to recite the information and the presentation it makes presentation become boring and i want leave some passions for the presentation. but of course i need know the information very well but just not trying do the presentation in the same way, for me every presentation is different even some times i was regreted because i missed some information but i think it at least can first make ourslves interested in our presentation. i beleive if the speaker do not interested in his or her presentation it will be hard to make others interested in it.

the large population

Nowadays the glogal population stand on 6 billion, and only in china there are 1.4 billion people how many food and water they need to eat and drink? the food supply is become a big problem not only in the developing countries but also in the developed countries. In china there is about 800 million people live in the village they can not get enough eduction and healthy service even china has the fastset GDB increasing in the world. As i know in order to increase the develop of economic chinese grovernment has no extral resource to control the food price and it is getting highter and highter let us imagin if china has only 600 million people may be now china is not a developing country but a developed country which can play more important role in the world economic.
