A、 Those units means that they can prevent it from eroding.
B、 Those units provide a method of deicing.
C、 Those units provide a way to prevent the formation of ice.
答案：C
解析：这道题考察的是关于防止结冰的方法。选项A中提到防止侵蚀，与题目中提到的防止结冰不符；选项B提到除冰方法，与题目中提到的防止结冰类似，但不完全符合；选项C提到提供一种防止结冰的方式，与题目中的意思一致，所以答案应该是C。
为了更好地理解这个知识点，我们可以通过生动的例子来帮助理解。想象一下，当天气变得非常寒冷时，我们的车窗可能会结冰，这会给我们的驾驶带来很大的困难。为了防止车窗结冰，我们可以使用一种特殊的喷雾剂，这种喷雾剂可以在车窗上形成一层薄薄的保护膜，防止冰的形成。这种喷雾剂就像题目中提到的那些单位，提供了一种防止结冰的方式，让我们的车窗保持清晰，确保我们的安全驾驶。

A. Landing gear is left for ten minutes.
B. Landing gear should be kept extended for ten minutes.
C. Extend landing gear after ten minutes＇ retraction.
解析：这道题是关于飞机起落架的操作指令。在这个情景中，指令是让起落架延长十分钟。正确答案是B，即起落架应该被延长十分钟。这个指令是为了确保起落架在使用前得到充分的检查和准备，以确保飞行安全。
举个生动的例子来帮助理解这个知识点：想象一下你是一名飞行员，你的飞机刚刚降落在机场，地面工作人员告诉你要将起落架延长十分钟。这意味着你需要按照指令将起落架保持在延长状态，以便地面工作人员可以进行必要的检查和维护工作。只有在起落架得到充分准备之后，你才能安心地继续下一次飞行。这个例子帮助你更好地理解了为什么起落架需要被延长十分钟这个操作指令的重要性。
A. For "emergency", the related failure should be responded immediately, for example, the total engine failure, fire or smoke, sudden cabin pressure lost.
B. An "Emergency" almost including a serious failure that requires later response, such as a total engines failure, flame out or smoke, or rapid cabin pressurization.
C. For "emergency", the related failure should be treated immediately, for example, the total engine is not malfunctioning, fire or smoke, sudden cabin pressure lost.

A. Make sure that there is airflow in the pipe to hinder .
B. Make sure that there is something in the pipe to block the airflow.
C. Make sure that there is nothing in the pipe to hinder airflow.
解析：这道题考察的是关于管道通风的知识。正确答案是C:Make sure that there is nothing in the pipe to hinder airflow.
在管道通风中，我们需要确保管道内没有任何堵塞物，以确保空气能够顺畅地流动。如果管道被堵塞，空气无法流通，会影响到管道的正常使用。
举个生动的例子，就好像我们的呼吸道一样。当我们呼吸时，我们希望空气能够顺畅地进入我们的肺部，如果我们的呼吸道被堵塞，比如说我们感冒时鼻子被堵住了，我们就会感到呼吸困难。所以，保持管道畅通就像是保持我们的呼吸道畅通一样重要。
