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.
