Grammar - information and contents
This exercise practises nouns which can be both count and non-count, usually with different meanings. Read the sentences and put the correct words in the gaps. Make sure you put them in the correct forms in the singular or plural with a definite or indefinite article where necessary. Remember, count nouns must take an article or the plural. Non-count nouns do not take an indefinite article or the plural. Each word is used twice, once as a count and once as a non-count noun.
