Questions on specific points regarding translating Chinese. Do your own research first!
Translation questions are not for asking things that you could answer yourself by looking into a dictionary or doing a simple search on the internet – this is not a translation service. When you ask a question like this, please show that you've already done some research, and explain what else you need to know.
Unfortunately automatic translation tools aren't perfect, but Google Translate has become pretty good for Chinese-English and English-Chinese. Simple sentences are usually translated with good accuracy.
