Pray for Sichuan China

There is bad news for Sichuan China.

Tragedy had struck in the Sichuan Province of China recently. 

I made it sound better, more like a sentence on a news article. 

The earthquake had happened in Ya'an Sichuan China on 20 April.

On April 20th, 2013 an earthquake had struck the city of Ya'an. 

It is tragic. The earthquake was 7 magnitude, a lot of people's houses were destroyed by earthquake.

It is very unforunate, the earthquake was a 7.0 magnitude on the Richter scale, and a lot of houses and buildings were devastated. 

The worst of thing was that so many people were died and injured in this earthquake.

Even worse, more than 190 people died and more than 10,000 people have been injured.

Maybe it would be better if you are specific, maybe talk about how many people died and injured?
Even though this tragedy had happened,but i still believe we will tide over this difficulties.

Even though this tragedy had occured, I still believe we will persevere over this difficult event. 

Cause our government has made measures for the victims of a natural calamity, including stars, residents donated money and goods for daily use.

The reason is that our government is better prepared to help the victims of this natural calamity. Celebrities and residents have even donated money and goods for daily uses.

Made this sentence into two sentences to make it sound better.

Everyone is trying to help Sichuan. Chinese people are very brave and united

Everyone is trying to help Sichuan and the Chinese people are very brave and will stand united. 

Also made it sound better.
Please pray for Sichuan China. Thank you.

Please pray for Sichuan and for all of China. Thank you. 

Also made it sound better.  

中国四川有一个不好的消息。在4月20日一场地震发生在了中国四川省雅安。这是悲痛的。地震是7级，很多人的房子被地震所摧毁，最糟糕的事情是有很多人在地震中死亡和受伤。
尽管这个悲剧已经发生，但是我仍然相信我们会克服这些困难。因为我们的政府已经对灾民采取措施，包括明星，公民们也在捐款和捐日常生活用品。每个人都尽力帮助四川。中国人民是很勇敢和团结的。
请为中国四川祈祷。谢谢

Hopefully the situation in Sichuan will improve and the people will keep the Sichuan Province in their thoughts and prayers, especially the Chinese communities all over the world.
