Bit by bit, he makes the necessary changes to make his language like other people’s. 72 They learn to do without being taught to walk, run, climb, whistle, ride a bicycle, compare their own performances with those
of more skilled people, and slowly mak
e the needed changes.

right answer, as it may be in mathematics or science, give him the answer book. 74 Why should we teachers waste time on such routine work? 75 Let the children learn what all educated people must some day learn, how to measure their own understanding, and how to know what they know or do not know.
