问题     In some early attempts by psychologists to describe the basic learning process, the terms ’stimulus’, ’response’ and ’reinforcement’ were introduced. In an educational setting, these (1)_____ could be defined as follows. When a teacher gives an (2)_____, or sets a problem, or asks a question, the pupil (3)_____ in some way, and the teacher then tells the pupil if he has responded correctly. The teacher’s first action is called the (4)_____. The pupil’s action, carrying out the instruction, or solving the problem, or answering the question, is (5)_____ the response. When the teacher tells the pupil his response is (6)_____, the bond between the stimulus and the response is strengthened and reinforcement is positive. If the response is incorrect, the bond is weakened, and reinforcement is (7)_____
    Some psychologists laid great (8)_____ on the importance of reinforcement for continued learning. They (9)_____ that if a learner is not given information about his responses (feedback) he may not continue to respond. (10)_____, if his homework is not marked regularly, he will stop doing it. If in class, the answers he gives to the teacher’s questions are (11)_____ or brushed aside, he will stop trying to give any.
    Educational psychologists are, (12)_____, moving away from this simple, early (13)_____ of the basic learning process. The effects of feedback, for example, are seen to be more (14)_____ than this description suggests. Feedback does not merely positively or negatively (15)_____ the stimulus-response bond. It may (16)_____ confirm previously learned meanings and associations, correct mistakes, (17)_____ misunderstandings and show how well or badly different parts of the material have been learned. Thus (18)_____ may have the effect of increasing the learner’s confidence, backing up his previously (19)_____ knowledge, and showing him which items he has not (20)_____ grasped.


选项 A、however
B、therefore
C、furthermore
D、otherwise

答案A

解析 逻辑衔接题。实际上,从本句的语法结构就可以直接判断出本题的正确选项。however这个词比较特殊,该词放在句中时必须与前后部分用逗号隔开。将however放回句中该句意思为:但是,教育心理学家现在正慢慢淘汰这种基础的学习过程模式。therefore意为"因而",表示因果关系;furthermore意为"此外,而且",表示递进关系;otherwise意为"否则",表示选择关系,均不符合该处上下文逻辑关系。
