Inquiry on TOEFL, Please help out

Hi,
I have couple questions about TOEFL.

1) is there any difference taking TOEFL in China and USA?

2) I heard there is a paper based test in USA, is that true?

3) where can I download the test material (TOEFL), real exams.

Thank you

1.china的TOEFL是筆考的,明年也會改成新托福,usa的TOEFL是機考的,200509改成新托福

2.應該沒有,,usa就算有也是非正式的,
