Provide examples of double comparatives.

Double comparatives are formed by using two comparative forms together in a sentence to emphasize the degree of comparison. They are used to express a higher degree of comparison than the regular comparative form. Here are some examples of double comparatives:

1. The more I study, the better my grades become.
2. The faster you run, the sooner you will reach the finish line.
3. The harder you work, the more successful you will be.
4. The more you practice, the better you will become at playing the piano.
5. The earlier you arrive, the better seats you will get.
6. The more you save, the more money you will have in the future.
7. The more you exercise, the healthier you will be.
8. The more you read, the more knowledgeable you become.
9. The more you practice speaking, the more fluent you will become in a foreign language.
10. The more you invest, the higher your returns will be.

In these examples, the double comparatives are used to show that the degree of the second comparative is dependent on the degree of the first comparative. They highlight the cause and effect relationship between the two comparative forms.
