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 meters, 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 meters from your vessel．

Leave the area slowly, gradually moving faster when you are more than 300 meters 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 travelling side by side with whales．

When whales are travelling 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 meters 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．

【解析】

这是一篇说明文。渔业和海洋部门已经制定了约翰斯通海峡观鲸的指导方针，每年夏天在那里每天都能发现虎鲸。短文介绍了船只经营者对所有种类的鲸鱼必须遵守的操作规则。

1.推理判断题。根据第一段最后一句话It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales．可知，这些对各种各样的鲸都必须遵守的操作规则被强烈地推荐给船只操作员。由此判断出文章是写给船只操作员的。故选C项。

2.细节理解题。从操作规则第四、五条“Start your boat only after the whales are more than 100 meters from your vessel．Leave the area slowly, gradually moving faster when you are more than 300 meters from the whales”可知：在一百米之外，才能启动船只；三百米之外，才逐渐加速。所以离开观测区域时，应逐渐加快航速。故选B项。

3.细节理解题。根据操作规则第八条Keep at low speeds and remain in the same direction if travelling side by side with whales．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。故选A项。

4.细节理解题。根据从操作规则第二条Approach no closer than 100 meters, then stop the boat but keep the engine on．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。故选D项。
