Examples
example 1
[0021] Example 1, is the evaluation multiple choice question type example of the present invention (physics of the second grade in junior middle school)
[0022] Please choose the correct answer in the following multiple choice questions.
[0023] Test code:
[0024] WLB201 (Description of test codes: physics, junior high school sophomore course, next semester, first test)
[0025] Please select the correct option:
[0026] 1. The mass of an object is 2.5×10 7 mg, the object may be
[0027] A an elephant B an elementary school student C an ant
[0028] D a rabbit E a physics book
[0029] Tip: Pay attention to the conversion of mass units and the mass of some common objects
[0030] Dial: 2.5×107mg converted into kilograms should be 25kg, and 25kg is often said to be 25 kilograms in life, that is, 50 catties should be the mass of a primary school student.
[0031] 2. Which of the following statements about quality is correct:
[0032] An object at rest has mass, an obj...
example 2
[0074] Example 2, is the evaluation and judgment question type example of the present invention (first grade mathematics at the beginning)
[0075] Test code:
[0076] SXB105 (Description of test codes: Mathematics, first-year junior middle school courses, next semester, fifth test)
[0077] Please judge whether the following conclusions are correct, please fill in 1 in brackets if it is correct, and fill in 0 if it is incorrect.
[0078] 1. Calculate -x 2 ·(-x) 2 equal
[0079] (1)-x 2 ·(-x) 2 =(-x) 2+2 =(-x) 4 =x 4 ()
[0080] (2)-x 2 ·(-x) 2 =-x 2 x 2 =-x 2+2 =-x 4 ()
[0081] (3)-x 2 ·(-x) 2 =-x 2 ·(-x 2 )=-x 2+2 =-x 4 ()
[0082] (4)-x 2 ·(-x) 2 =-x 2 x 2 =-x 2×2 =-x 4 ()
[0083] 2. It is known that a=3 55 , b=4 44 , c=5 33 , compare the sizes of a, b, and c. Try to judge:
[0084] (1) The bases and exponents of the three numbers in this question are different, so they cannot be compared; ()
[0085] (2) They must be transformed into t...
