The berthing angle is the angle between heading and shoreline of the wharf. Usually, the berthing angles not equal to the approaching angle. The approaching angle should be altered to the berthing angle prior to the ship's lateral moving to the wharf. Altering the approaching angle, when there is a wide angle between the berth and the channel or fairway, is the process equivalent to a large angle of heading altering. The approaching angle is correlated to the area of touch at the time a ship contacts her berth. If the berthing angle not zero degree, the area of first touch maybe small, the hull of the ship may touch only one fender furnished at the wharf and may damage the structure of berth and/or the hull of herself if her transverse speed is a bit fast. Ship's heading should be parallel to the wharf at the moment she contacts whatever the way is employed to move the ship close to her berth.Usually, the larger is the displacement, the smaller is the angle of close to be employed. The stronger is the current a full loaded ship is moving against, the smaller is the angle. The stronger is the off shore wind, the larger is the angle for a light loaded ship. A ship of small size can employ a small berthing angle and of medium or large size must employ zero berthing angle to move laterally with her ship's heading kept parallel to the wharf as her huge inertia difficult to be controlled.The berthing angle is the angle between ____ and ____.A channel; berthB heading; berthC heading; channelD course; channel

题目解答

答案

我们来逐步分析这道题目：

一、题目解析：

题目问的是：

> The berthing angle is the angle between ____ and ____.

这是一个填空题，要求我们填入两个对象，它们之间的夹角就是 berthing angle（靠泊角）。

二、从原文中提取关键信息：

原文第一句话就是：

> The berthing angle is the angle between heading and shoreline of the wharf.

这句话直接给出了定义：

> 靠泊角是船舶航向（heading）与码头岸线（shoreline of the wharf）之间的夹角。

三、选项分析：

我们来看选项：

  • A. channel; berth
    —— 航道和泊位之间的角度，不符合原文定义。

  • B. heading; berth
    —— 航向和泊位之间的角度，虽然“泊位”是靠泊的目标，但原文明确说的是“shoreline of the wharf（码头岸线）”，而不是“berth”这个词。

  • C. heading; channel
    —— 航向和航道之间的角度，这更像是“approaching angle（接近角）”，而不是berthing angle。

  • D. course; channel
    —— 航迹和航道之间的角度，也不是berthing angle的定义。

四、正确答案：

虽然选项中没有“shoreline of the wharf”，但最接近原文定义的选项是：

> B. heading; berth

虽然“berth”不如“shoreline of the wharf”准确，但在选项中它是唯一一个包含“heading”的选项，而原文明确指出“berthing angle is the angle between heading and shoreline of the wharf”。

✅ 最佳答案是：

$\boxed{B}$

解析

本题考查对靠泊角定义的理解。解题思路是从题目所给的原文中找到关于靠泊角的定义描述，然后将其与各个选项进行对比。
根据原文“The berthing angle is the angle between heading and shoreline of the wharf”可知，靠泊角是船舶航向（heading）与码头岸线（shoreline of the wharf）之间的夹角。
接下来分析各个选项：

  • A选项“channel; berth”，航道和泊位之间的角度，与原文定义不符。
  • B选项“heading; berth”，航向和泊位之间的角度，虽然“泊位”不完全等同于“码头岸线”，但在选项中它是唯一一个包含“heading”的选项，最接近原文定义。
  • C选项“heading; channel”，航向和航道之间的角度，这更像是“approaching angle（接近角）”，而不是靠泊角。
  • D选项“course; channel”，航迹和航道之间的角度，也不是靠泊角的定义。
