Hello,everyone!It's my honor to have a speech here.London will host the 2012 Olympic Games.The organizers will take "One Planet Olympics" environment protection policy.The organizers are going to take many measures to make the aim come true.First,they plan to use some new energy instead of oil so that there will be less air pollution.Second,they will use recycled materials to make the chairs and tables of the stadiums,many materials can be recycled.Third,they are going to try their best to reduce garbage and cut the greenhouse gases.They are sure to have an exciting and environmental Olympics.The slogan for the London Olympic Games is"inspire a generation" that was announced in the 100-day countdown ceremony.It's the heartbeat,the rallying cry for the athletes that come to UK .They perform well and inspire the world.With the applause and laughter flying around,the 30th Olympic Games is coming.Generally speaking,Olympic is not only a simple sport,but also another name for sports spirit.Let''s hope the London Olympic held successfully and look forward to China in the 30th Olympic Games can reach new heights.
帮忙看看有没有错,

感觉上整篇都写得不错,但是最后一句似乎可以修正：
“Let's hope (that) the London Olympic will be held successfully and look forward to China reaching new heights in the 30th Olympic Games." 括号中的字可要可不要.
前部分 London Olympic 应该 是被成功的举办,所以 要用 ”be held“,would 或者will 都可以； 而后面部分由于是 固定搭配 ”look forward to+ ing“,所以 应该用 reaching,结构就相应的对调一下,变成上面给的句子.

The slogan for the London Olympic Games is"Inspire A Generation" that was announced in the 100-day countdown ceremony.我觉得只有这个地方要大写 其余的很好。
