翻譯修改!!滑水 - 社會議題

請各位大大幫我修改以下數篇文章的翻譯(寒假作業)
1.
A Water Ski Racing team consists of a boat driver, an observer and a skier. The driver will tow the skier behind a boat, varying the speed as different water conditions are encountered, according to the driver's knowledge of the skier, the observer's ability to read the skier and the signals which the skier gives to the driver.
滑水賽隊伍包括船長、觀察員和滑雪者。船長將拖曳滑雪者在汽艇後面。而觀察元將觀察水面及滑水著的情況，再向船長說應變化的速度。

A Water ski show usually involves an entertaining theme, music, multiple boats, and a variety of acts including jumping, swiveling, ballet line, barefooting, doubles, wakeboarding, and the popular pyramids. In a tournament, teams have one hour to perform their show. A panel of judges decide the outcome. Scoring involves the difficulty, crowd appeal, flow, and execution of each act. Also scored are sound/announcing, boat driving, safety-boat driving, dock and equipment, showmanship, and the overall show as a whole.

Update:
幫主先生，您所使用的翻譯器應該是:
Yahoo奇摩搜尋語言工具---段落翻譯
翻譯服務是由 SYSTRAN / Yahoo!奇摩 提供
拜託，火燒屁股了
我上面那段文字就是由Yahoo翻譯修改的(修改很多)
不能有比較personal的文字嗎?
