寒假听力养成记（六级）

What should a pilot do if he wants the plane to spin?

A、Turn the fins in the desired direction.

B、Turn the fins together in the same direction.

C、Turn the right fin up and left fin right.

D、Turn one side rising and one side dropping.

【听力原文】

To make a turn on the lateral or vertical axis, a pilot 

needs only to turn the fins in the direction of the 

desired turn. For example, if the pilot wants to turn 

left, he would turn the vertical axis left. The air stream 

that flows around the aircraft would change, and the 

aircraft would turn left.

To achieve a spin, the fins go in opposite directions. 

For example, to spin clockwise, the right fin would 

turn down, so the right side of the aircraft drops. 

The left fin would turn right, so that the left side 

of the aircraft would rise. (19) With one side rising 

and one side dropping, the aircraft then would perform a spin or roll.

【听力译文】

要操作横轴或者垂轴，飞行员只需将腹鳍朝着目标方向推动。例如，如果飞行员想左转，就将垂轴向左推。飞机周身的气流将会改变，飞机将会左转。

想让飞机旋转，腹鳍转动与水平轴推向相反方向相反。例如，想让飞机顺时针旋转，右腹鳍会下降，所以飞机的右侧会下降。左腹鳍会右转，这样飞机的左侧会上升。飞机一侧抬升一侧下降，这样飞机就能实现旋转。

【听力解析】

听力原文中提到 With one side rising and one side dropping, the aircraft then would perform a spin or roll.由此可知，想让飞机旋冲，要让飞机的一侧升高，而另一侧下降，故选项 D 为答案。选项 B 和 C 的信息听力原文未提及，而选项 A 为飞机升降和左右转向的操作方法。
