Some people dream of flying．For a doctor and his wife from Sydney, this dream is becoming true．Glenn Singleman and Heather Swan wear specially designed "wing suits" to jump from great height and fly over the large, dry land．

    They plan to set a record with a flight from a hot-air balloon flying 12,000 meters above the middle of the country．Singleman and Swan would reach a top speed of 400 kilometers per hour．

    The Sydney Morning reports that the couple plan to make even higher jump from an airplane．For jump from great height, they carry extra oxygen as well as a Global Position System unit （全球定位系統(tǒng)）, so they can be found once they've reached the ground．

1．Where are the Singlemans from?

2．How fast would they reach per hour to set a flight recorder?

3．What's the Sydney Morning, do you think?

4．For making higher jump from an airplane, they will carry something．Give an example．
