若用丙装置收集生成的氧气，气体应从______（选填“c”或“d”）端导入．

Culture is activity of thought, and receptiveness to beauty and human feeling. (1) of information have nothing to do with it. A merely well-informed man is the most useless (2) on God’s earth. What we should (3) at producing is men who (4) both culture and expert knowledge in some special direction. Their expert knowledge will give them the ground to start (5) , and their culture will lead them as (6) as philosophy and as high as (7) We have to remember that the valuable (8) development is self-development, and that it (9) takes place between the ages of sixteen and thirty. As to training, the most important part is given by mothers before the age of twelve.

In training a child to activity of thought, above all things we must (10) of what I will call "inert ideas"—— that is to say, ideas that are merely (11) into the mind without being (12) , or tested, or thrown into fresh combinations.

In the history of education, the most (13) phenomenon is that schools of learning, which at one epoch are alive with a craze for genius, in a (14) generation exhibit merely pedantry and routine. The reason is that they are overlade with inert ideas. Except at (15) intervals of intellectual motivation, education in the past has been radically (16) with inert ideas. That is the reason why (17) clever women, who have seen much of the world, are in middle life so much the most cultured part of the community. They have been saved from this horrible (18) of inert ideas. Every intellectual revolution which has ever stirred humanity (19) greatness has been a (20) protest against inert ideas.
