When I write Chinese, if there is a sentence I'm not 100% confident with I put the sentence in to Google. If you find 0 websites, it means your sentence is probably wrong! Get it?

Hello Lucia, Check this link for potential grammar check soft wares to check both your grammar and spelling mistakes. You can download any for a trial period and then purchase it i guess: http://wareseeker.com/Business-Finance/grammar-check-anywhere-2009.zip/5d0f4fc49 Well 李汉伦 ,but that won't point out the grammar mistakes, if you put in Google even any unrelated set of words ,there will appear lots of websites, Google doesn't work according to the grammatically correct sentences ,rather search by the words input. Just try to put some words in English that don't make a grammatically correct sentence ,still you will get loads of sites,e.g " She have 3 dog". It is grammatically wrong ,google it !;) Maybe it is different with Chinese ?!?I don't think so ,try unrelated words as well.

If you use Microsoft Word, it will point out some obvious grammar and spelling mistakes. For the sentence you wrote, it point out that "articles" is spelled wrong. And "Is there any website help people" is worded incorrectly. But it doesn't point out all the mistakes though. There are always a lot of grammar mistakes found in my articles, which I didn't even realize when I was writing... How can I avoid this? Is there any websites that help people to find out their grammar mistakes?

wow! google is so amazing

for starters, you can use microsoft word, although this is somewhat limited in catching grammar mistakes
