Section A
Directions：Translate the following passage into Chinese. Write your translation on the ANSWER SHEET.
The standardized educational or psychological test that are widely used to aid in selecting，classifying，assigning，or promoting students，employees，and military personnel have been the target of recent attacks in books，magazines，the daily press，and even in congress. The target is wrong，for in attacking the tests，critics divert attention from the fault that lies with ill-informed or incompetent users. The tests themselves are merely tools，with characteristics that can be measured with reasonable precision under specified conditions. Whether the results will be valuable，meaningless，or even misleading depends partly upon the tool itself but largely upon the user.
