以下是高校招生官建議遵循的一些重要語法規則：

規則 1：修飾語（描述事物的單詞或短語）應靠近其修飾的單詞或短語。

示例：Purchased last week, the new preparation materials helped the student study.

常見錯誤：Purchased last week, the student studied with her new preparation materials.

規則 2：確保代詞指代一個特定的名詞，并與其指代名詞的單數或復數形式保持一致。

示例：The professor is a favorite at the university, but he is now taking a semester off.

常見錯誤：The professor is a favorite at the university, but they were now taking a semester off.

規則 3：牢記句子主語，確保主語始終與動詞保持一致。

示例：Each of the authors involved in writing the book was a sociologist.

常見錯誤：Each of the authors involved in writing the book were sociologists.

規則 4：當一個句子中存在兩個或多個并列成分時，應使用同類語法形式。

示例：The teacher thought he was a good student because he turned in his papers on time, tested well on exams and appeared enthusiastic.

常見錯誤：The teacher thought he was a good student because he turned in his papers on time, tested well on exams and his enthusiasm was high.

規則 5：當主語是動作的執行者時，選擇主動語態（而非被動語態）。

示例：After I spent the past semester meeting with my study group in the library, I decided to change the location.

常見錯誤：After meeting in the library with my study group for the past semester, changing locations was my decision.
