我想知打高爾夫球的洞有幾大及守則

個洞直徑108mm（4.25吋）．
打球規則你自己慢慢睇啦（貼咗響度）．

高爾夫球，俗稱小白球，是一種室外體育運動。個人或團體球員以不同的高爾夫球桿將一顆小球打進果嶺的洞內。高爾夫球像是起源自蘇格蘭。大部份的比賽有18洞。桿數越少的越優勝。
高爾夫各球洞因地形變化而出現不等的距離，通常將此不等的距離分成：長，中，短三種。十八個球洞中，長，短距離的球洞各有四個，中等距離的球洞有十個，採混合式排列。
不同距離的標準桿數：431米以上為5桿，430.9米至229.1米為4桿，229米以下為3桿，一回合的比賽大都以72桿為準，也有一回合設定為70桿的，如美國公開賽大都設定70桿，以增加比賽的困難度，通常一場比賽要比四個回合，女子組通常是三個回合。
The cup is always found within the green (at least ten feet from the edge), and must have a diameter of 108 mm (4.25 in.) and a depth of at least 100 mm (3.94 in.).

Golf rules and other regulations
The rules of golf[2][3] are internationally standardised and are jointly governed by the Royal and Ancient Golf Club of St Andrews (R&A), which was founded 1754 and the United States Golf Association (USGA). By agreement with the R&A, USGA jurisdiction on the enforcement and interpretation of the rules is limited to the United States and Mexico. The national golf associations of other countries use the rules laid down by the R&A and there is a formal procedure for referring any points of doubt to the R&A.
The underlying principle of the rules is fairness. As stated on the back cover of the official rule book: "play the ball as it lies", "play the course as you find it", and "if you can't do either, do what is fair". Some rules state that:

every player is entitled and obliged to play the ball from the position where it has come to rest after a stroke, unless a rule allows or demands otherwise (Rule 13-1)
a player must not accept assistance in making a stroke (Rule 14-2)
the condition of the ground or other parts of the course may not be altered to gain an advantage, except in some cases defined in the rules
a ball may only be replaced by another during play of a hole if it is destroyed (Rule 5-3), lost (Rule 27-1), or unplayable (Rule 28), or at some other time permitted by the Rules. The player may always substitute balls between the play of two holes.
The Decisions on the Rules of Golf are based on formal case decisions by the R&A and USGA and are revised and updated every other year.
There are strict regulations regarding the amateur status of golfers.[4] Essentially, everybody who has ever received payment or compensation for giving instruction or played golf for money is not considered an amateur and may not participate in competitions limited solely to amateurs. However amateur golfers may receive expenses which comply with strict guidelines and they may accept non-cash prizes within the limits established by the Rules of Amateur Status.
In addition to the officially printed rules, golfers also abide by a set of guidelines called golf etiquette. Etiquette guidelines cover matters such as safety, fairness, easiness and pace of play, and a player's obligation to contribute to the care of the course. Though there are no penalties for breach of etiquette rules, players generally follow the rules of golf etiquette in an effort to improve everyone's playing experience.

打球守則
球手若不能在五分鐘內尋到遺失的球便視為遺失球。在尋找失球時，請讓後一組）的球手先行通過。

球手應與球會職員及巡場員共同合作，加快其他組別的球打球節奏。

出發員有權將球手合組或分組成最少三人一組出場。

無論球技好壞，“快走慢打”是要時刻記住的，球打出去之後快走幾步，所有的人都會感激你。

在練習揮桿時一定要真的做到“空揮”不要傷到草皮，在發球區的時候更是如此，一些球員在進行練習揮桿時毛病很多，每次打球之前都要揮上個三四次，而且次次都要刮下一大塊草皮，對球場造成很大的傷害。

在打球的時候(比賽時除外)如果偶然失誤了，再多打一只球作為練習並無大礙，但是千萬不要過分，球場上經常有人打壞了再打一個，再打壞再打一個，再打壞再……於是球場上出現了N多個球

果嶺的洞
很早以前是沒有規定，一直到1891年才由英國皇家高爾夫協會（簡稱R＆A）加入規則裡，規定果嶺上球洞的大小為直徑4.25inch。所以現在球場都是使用一個標準尺寸的挖洞器在挖洞。

由來：

1891年時R＆A因為要發布高爾夫新規則，發現高爾夫果嶺上的球洞也必須規定大小。會決定這個大小，是在當時在MUSSELBURGH市有一個9洞的市立高爾夫球場，他們在1829年起就有發明一種挖洞的道具一直在使用，規格是直徑4.25inch，因此R＆A就決定採用4.25inch為規則上標準的大小。
這個古老的挖洞器至今仍然被保存在ROYAL MUSSELBURGH高爾夫俱樂部裡，但是並沒有對外展示。
