It is always beneficial to review grammar and punctuation. These fundamental aspects of language play a crucial role in effective communication. By brushing up on grammar, we can ensure that our sentences are structured correctly, making our ideas more清晰易懂. Punctuation, on the other hand, helps to clarify the meaning and rhythm of our writing. A misplaced comma or a missing period can completely change the intended message. Therefore, taking the time to improve our grammar and punctuation skills is well worth the effort. Whether it's through reading grammar books, practicing with exercises, or seeking feedback from others, there are many ways to enhance our language proficiency. So, let's make it a habit to regularly review and refine our grammar and punctuation, and watch our communication skills soar!
