1. Contrasted comparatives.
Two comparative expressions preceded by the are used to show how a change in one thing is linked to a change in another thing.
The thicker fries are, the less fat they soak up during cooking.
In both clauses the word order is:
the + comparative [+ clause], the + comparative [+ clause]
The more you eat, the fatter you get.
Put these words in order to make one sentence that is similar in meaning to the two sentences.
For more information about contrasted comparatives see the Grammar Reference.
