CDo’s and Don’ts in Whale(鲸) Watching The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales.· Approach whales from the side, not from the front or the back.· Approach no closer than 100 metres, then stop the boat but keep the engine on.· Keep noise levels down — no horns, whistles or racing of engines.· Start your boat only after the whales are more than 100 metres from your vessel.· Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.· Approach and leave slowly, avoiding sudden changes in speed or direction.· Avoid disturbing groups of resting whales.· Keep at low speeds and remain in the same direction if traveling side by side with whales.· When whales are traveling close to shore, avoid crowding them near the shore or coming between the whales and the shore.· Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.· If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.· Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.小题1:64.

小题3:从操作规则第八条可知：当船只和鲸并排前进时，保持低速且应同一个方向前进。
小题4:从操作规则第二条可知：靠近鲸不能低于一百米，然后停止，但要让发动机开着。所以最近的安全观察距离应是100米。
