ENGLISH GRAMMAR – WORKSHEET #1: Nouns

The singular form is crisis and the plural form is crises. MOST OF THE FOLLOWING SENTENCES CONTAIN ERRORS THAT ARE OFTEN MADE. CORRECT THEM! It took me a hour to get there. → an hour. The indefinite article is an, not a, when directly followed by a vowel sound. Note that spelling has got nothing to do with it, only sound! ................
