Question

Do’s and Don’ts in Whale(鯨) 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

1.從第一段最后一句話可知：這些對(duì)各種各樣的鯨都必須遵守的操作規(guī)則被強(qiáng)烈地推薦給船只操作員。
2.從操作規(guī)則第四、五條可知：在一百米之外，才能啟動(dòng)船只；三百米之外，才逐漸加速。
3.從操作規(guī)則第八條可知：當(dāng)船只和鯨并排前進(jìn)時(shí)，保持低速且應(yīng)同一個(gè)方向前進(jìn)。
4.從操作規(guī)則第二條可知：靠近鯨不能低于一百米，然后停止，但要讓發(fā)動(dòng)機(jī)開著。所以最近的安全觀察距離應(yīng)是100米。
