Complete using the present simple or the present continuous. They _______ (come) to the market. Mrs Shaw always _______ (buy) some potatoes from Mr Green.

The correct answers are 'come' and 'buys'. The first sentence speaks of a regular action, thus we use the present simple. Since the subject 'they' is plural, we use the base verb 'come'. The second sentence involves 'always', indicating a regular action so we use present simple. Mrs. Shaw is singular so we add -s to the verb ‘buy’. Therefore, the completed sentences are: 'They come to the market. Mrs Shaw always buys some potatoes from Mr Green.'
