Within the pages of this comprehensive workbook, children are provided with numerous practice opportunities to master the use of comparative and superlative forms. By selecting the correct adjective or adverb to fill in the blanks, students improve their grammar and enhance their overall linguistic competence. These thoughtfully crafted exercises are designed to solidify knowledge of how and when to use terms like "taller," "tallest," "more diligently," and "most diligently." As a result, children will develop stronger, more nuanced communication skills, preparing them for more advanced language challenges.

For example, to fill in the blank in the sentence "I think summer is BLANK than winter" with the given choices, you need to use the comparative form of the adjective "good."

Here are the choices:

- Choice A. Good

- Choice B. Better

- Choice C. Best

The correct comparative form of "good" is "better." The word "better" is used to compare two things: summer and winter.

Therefore, the correct way to fill in the blank is:

"I think summer is better than winter."

So, the correct choice is B. Better.
