Questions 46 to 50 are based on the following passage. Ron Barrister awoke once again with a slight ringing in his ears. After he showered and dressed, the condition got worse. He was also short of breath. When he looked in the mirror to see if his tongue were coated or if there were some other signs of a cold coming on, he noticed that his eyes looked peculiar. He turned sideways and looked again. Sure enough, his eyes seemed to be bulging out. He decided to explain his symptoms to Dr. Klien, the eye, ear, nose, and throat specialist. Dr. Klien examined Ron very carefully. After a complete examination he was stumped. Everything appeared normal and tests showed no signs of disorder. “Ron,” he said, “I really can’t find anything wrong, and I’m at a loss to explain your strange symptoms. However if you’d like another consultation, Dr. Brown is next door. She might be able to discover something I missed.” After another full examination, even Dr. Brown was stumped. “I can think of nothing to tell you except that you should be admitted to the hospital for a closer examination.” When Ron was being admitted to the hospital, the nurse asked him, “What size pajamas do you wear, Mr. Barrister” “I really don’t know,”he replied. “Well, do you know your shirt size” she asked as she reached for a measuring tape. “Yes,” answered Ron, “I wear 15.5 collar with a ...” The nurse measured his neck and said, “You mean a 16.5, don’t you” “No,” answered Ron, “I’ve always worn a 15.5 collar on all my shirts.” “O.K. but if you wear a 15.5 collar with your neck size, sooner or later you’re surely going to have a ringing in your ears, bulging eyes, and you’ll be short of breath.” Questions: What was the cause of Mr. Barrister’s uneasiness

A. His pajamas.
B. His neck.
C. His shirts.
D. His collars.

在中学物理教学中，教师要求学生从推动力、绳长和摆锤重量三个因素中找出影响单摆振动频率的因素。学生可以通过假定某两个因素保持恒定、依次改变第三个因素来看单摆振动频率的变化，借此找出问题的答案。而小学生往往会同时改变两个变量寻求解决方案，其结果是无法找出影响单摆振动频率的因素。请根据皮亚杰的思维发展阶段理论分析；该阶段的主要思维发展什么特征是什么？
