simulate_toefl_listening()

3. 增强听力技巧

提高听力技巧，如快速捕捉关键词、理解主旨大意、预测下文内容等。

代码示例（听力技巧训练）：

    print("Question: What is the main topic of the text?")
    print("A. The process of photosynthesis", "B. The importance of green plants", "C. The role of light energy in the environment", "D. The benefits of photosynthesis for humans")
    # 答案：A

listening_tips_training()

4. 模拟考试

进行模拟考试，熟悉考试流程和节奏。

代码示例（模拟考试计时器）：

import time

def toefl_simulation_timer(duration):
    start_time = time.time()
    while time.time() - start_time < duration:
        print(f"Time remaining: {int(duration - (time.time() - start_time))} seconds")
        time.sleep(1)

toefl_simulation_timer(60)

5. 持续复习

备考过程中，持续复习所学内容，巩固记忆。

代码示例（复习计划）：

        "tasks": ["Review vocabulary", "Practice listening exercises", "Take a full-length listening test"]
    }
    print(f"Day {plan['day']}:")
