named penicillin, turned to be an infection-fighting agent of 3. ______
enormous potency. When it was finally recognized as what it
was--the efficacious life-saving drug in the world--penicillin 4. ______

mental powers, in most cases, may end up in a faulty and inex- 14. ______
act command. What accounts of this difference? 15. ______
Despite other explanations, the real answer in my opinion
lies partly with the child himself, partly in the behavior of the 16. ______
people surround him. In the first place, the time of learning the 17. ______
mother tongue is the most favorably of all, namely, the first 18. ______
years of life. A child hears it speak from morning till night and, 19. ______
what is more important, always in its genuine form, with the
right pronunciation, right intonation, right use of words and right
