2017年12月16日，中国大陆举行了一年一度的英语四级考试。对于许多大学生来说，这是他们大学生涯中的一次重要挑战。四级考试的通过与否可能直接影响到学生的学业发展和就业前景。那么，2017年的四级考试总共耗费了多少时间呢？

首先，我们来看看四级考试的时间安排。四级考试分为听力、阅读、写作和翻译四个部分，考试时间一般为两个半小时。具体来说，听力部分包括听力理解和听写，一般耗时约40分钟。阅读部分包括长篇阅读和短篇阅读，一般耗时约60分钟。写作部分要求考生根据提供的题目写一篇短文，一般耗时约30分钟。最后，翻译部分要求考生将一篇中文短文翻译成英文，一般耗时约20分钟。综上所述，四级考试总共耗费了约150分钟，即2个半小时。

Now let's take a look at the time allocation for the 2017 CET-4 exam. The exam consists of four sections: listening, reading, writing, and translation, with a total time of two and a half hours. Specifically, the listening section includes both listening comprehension and dictation, which usually takes about 40 minutes. The reading section includes long passages and short passages, taking approximately 60 minutes. The writing section requires students to write a short essay based on the given topic, which usually takes around 30 minutes. Lastly, the translation section requires students to translate a Chinese passage into English, which usually takes about 20 minutes. In summary, the 2017 CET-4 exam took approximately 150 minutes in total, or 2 and a half hours.

除了考试本身的时间，准备四级考试也是一项耗时的任务。学生需要花费大量时间来复习和练习英语听说读写的各个方面。他们可能会参加辅导班、自习或请教老师，以提高他们的英语水平。此外，他们还需要做大量的练习题和模拟考试，以熟悉考试的形式和内容。因此，可以说准备四级考试同样需要耗费大量的时间和精力。

In addition to the actual exam time, preparing for the CET-4 exam also requires a significant amount of time. Students need to spend a lot of time reviewing and practicing various aspects of English, including listening, speaking, reading, and writing. They may attend tutoring classes, study on their own, or seek guidance from teachers to improve their English proficiency. Furthermore, they need to do a lot of practice exercises and mock exams to familiarize themselves with the format and content of the exam. Therefore, it can be said that preparing for the CET-4 exam also requires a substantial amount of time and effort.

总的来说，2017年的四级考试总共耗费了约2个半小时的考试时间，而准备考试所需的时间更加难以计算。无论是考试时间还是备考时间，都需要学生们付出大量的努力和时间。然而，通过这一过程，学生们不仅可以提高自己的英语水平，还能培养自己的学习能力和应对挑战的勇气。

Overall, the 2017 CET-4 exam took approximately 2 and a half hours of examination time, while the time required for exam preparation is even harder to calculate. Whether it is the exam time or the preparation time, students need to put in a lot of effort and time. However, through this process, students can not only improve their English proficiency but also develop their learning abilities and the courage to face challenges.
