1. The formula of calculating the area of rectangle is length width.

A) divided by B) multiplied by C) time by D) plus by

2. Among the following, which one is not a vector?

A) velocity B) force C) speed D) acceleration

3. It’s that keeps the aircraft flying.

A) the high velocity of air below the lower wing surface.

B) the pressure differential between the upper and lower surface of a wing.

C) the small area of upper wing surface.

D) the large area of lower wing surface.

4. Loading aircraft beyond the gross weight limitations may place dangerous stresses on the structure.

A) over B) far distance C) with D) below

5. We must convert the oil quarts gallons when we do the loading check.

A) to…to…B) from…to…C) to…for…D) from…at…

三．英译汉（30分）

1. Bernoull i′s principle helps to explain why an airplane flies，how a wing produces lift，and how fuel flows in an aircraft carburetor．

2. According to Bernoulli’s principle，as the velocity increases，pressure decreases, this causes a reduced pressure in the center of the venturi，while pressure remains the same at either end．

3. As the velocity of air increases over the upper surface of a wing，the pressure decreases, the imba1ance of forces between the upper and lower surfaces causes the wing to rise．

4. Over loading the aircraft beyond the gross weight limitations may place dangerous stresses on the structure，especially in rough air or during a hard landing．

5.Hand tools will fall into four basic categories：pounding tools，holding tools，cutting tools, and turning tools．

6. Warning：To avoid damage or injury，stay clear of main and nose gear operating parts when the red light is on．

四．段落翻译（34分）

1. Proper weight and balance is crucial to the safe operation of all aircraft．A review of principles you’ve learnt here and practice using the charts may be appropriate at this time．Take time to familiarize yourself with the information available on the type certificate data sheet，the aircraft specifications, and aircraft listings．The safety of the flying public depends in large part on the ability of professional aviation maintenance technician to properly calculate aircraft weight and balance figures．

2. Warning：Providing pneumatic power will supply pressure to the operating systems．Care should be taken to isolate those systems and controls not intended for operation to prevent loss of pressure to prevent inadvertent actuation of the equipment，damage to airplane and injury to personnel.

1.伯努利原理帮助解释了飞机为什么会飞，机翼如何产生升力以及燃料如何在飞机汽化器中流动等问题。

2.根据伯努利方程，当速度增加时，压力减少，这致使文氏管的中间有减小的压力，而在端部压力仍相同。

3.当机翼上表面的气流速度增加时，压力减少，机翼上下表面的压力差导致飞机上升。

4.超过最大重量极限的超载飞机可能在结构上产生危险的应力，特别是在不稳定气流中颠簸或粗猛着陆中更是如此。

5.手工工具分为四大类：敲击工具、夹持工具、切割工具和拧动工具。

6.警告：为避免损坏设备和伤害人员，在该红灯亮时，要远离主起落架和前起落架正在工作的零件。

四．段落翻译（34分）

1.正确的重量和平衡，对于所有飞机的安全使用，都是至关重要的。现在复习一下你学习的基本原理并练习使用这个计算表，也许是比较合适的。拿出一定时间让你自己熟悉一下飞机型号合格证数据单，飞机技术规范和飞机清单上备有的资料数据。飞机的安全性在很大程度上取决于专业航空维修技术人员正确计算重量与平衡数值的能力。

2.警告：提供气源后将向正在工作的系统供压，务必小心地隔离出不打算使用的那些系统和控制装置，以防止压力损失及偶然设备的制动会损坏飞机和伤害人员。
