The past tense of "study" is "studied." It refers to an action or a state that occurred in the past. Here is a paragraph of more than 100 words using "studied" in the past tense:

Last night, I studied for hours to prepare for my final exam. I meticulously reviewed my notes, textbooks, and supplementary materials. I created flashcards to help me memorize important concepts and definitions. I also practiced several sample questions and solved past exam papers to get a better understanding of the type of questions that could be asked. As I studied, I made sure to take breaks to rest my mind and avoid burnout. I wanted to ensure that I fully grasped each topic and felt confident in my knowledge. After a long night of studying, I finally went to bed feeling exhausted but satisfied with my efforts.

"Study"的过去式是"studied"。

在英语中，大多数动词的过去式是通过在动词的基本形式后面加上"-ed"来构成的。这种规则适用于许多常规的动词，包括"study"。例如，"I studied for the exam yesterday"（昨天我为考试学习了）。这种构成过去式的规则在英语语法中被广泛使用，并且对于大多数动词都是适用的。

2.以e结尾的动词直接加-d，e.g.dance-danced;

3.辅音字母加y结尾的，变y为i再加ed，e.g.study-studied;

4.以重读闭音节结尾，末尾只有一个辅音字母(字母w，y，x除外)，双写这个辅音字母加-ed， e.g. skip-skipped;
