Who Did It First? [antikvár]

FOREWORD The books of this series are intended for those who have left the age of fairy tales behind them, but require some reading material in easy English. The vocabulary of Stage 3 is limited to about 1,100 of the commonest words in English. At this stage the text may include all the tenses of the verb (Active and Passive), with the exception of the Future Perfect, but constructions involving might are not used. All normal subordinate clauses are admitted, though long and complicated sentences are avoided. NOTE TO THIS VOLUME The choice of subjects for this book has been mainly determined by the limited vocabulary. It would not be easy to treat such subjects as Penicillin or the work of Madame Curie in a vocabulary of 1,100 words, and for this reason many interesting chapters in man's history have had to be omitted. I would not like to say how many books have been consulted in the preparation of this volume, but students who are interested in any of the subjects treated will find the books which are listed on the next page useful.
