are made. It was a discovery that would change the course of the history. The active ingredient in that mold, which Fleming
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. ______
would alter forever the treatment of bacterial infections. By the

without knowledge or experience often succeeds to a complete 12. ______
master of the language. A grown-up person with fully developed 13. ______
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
structure. He drinks all the words and expressions which come to 20. ______
