今天给大家介绍的是雅思写作中的“时间对比”类题目，这类题目会让我们比较一个事物从过去发展到现在，它经历了一个怎样的变化。
首先让我们结合一道真题，来看一看时间对比题，它有哪三个要素。
People live in twenty-first century have a better quality of life than people who live in previous centuries. To what extent do you agree or disagree? （题目来源：2022年3月12日大陆雅思大作文）
通过真题我们可以分析出此类题目的三个要素。
● 要素一: 时间状语，它包含过去时间（in previous centuries）和现在时间（in twenty-first century）。
● 要素二：比较对象，此题比较对象是（quality of life）。
● 要素三: 比较级，通常为形容词+er形式，或者为more+形容词，此题比较级为better。
在此类时间对比题中，建议大家优先选择now比past更佳，推荐使用万能理由：
A.社会客观原因：社会经济发展、科技创新、教育改革、环境变化、政府政策优化等。
B.人为主观因素(需要根据题目来定)。
此题是一道观点类的大作文，讨论的是21世纪人们的生活质量是否变得更好。
同学们要注意题目中的比较关系，即“现在生活质量比以前更好/更差”。
根据时间对比题的万能切入点，我们可以从很多方面展开，如：交通、网络和通信、娱乐、医疗健康、居住环境、饮食等等，下面老师和大家来看看具体观点：
多种多样的交通工具极大地增加了人口的流动性。与过去的马车、人力车相比，快速交通，如汽车、飞机，给人们带来了速度与舒适感的极致体验。快速交通帮助人们打破了地理界限，人们可以在地球上几乎任何地形上旅行，无论是湍急的河流，崎岖的山脉，甚至是茂密的丛林。
A wide variety of transportation means have dramatically increased people’s mobility in the world. Compared with wagons and rickshaws, fast transportation, such as automobiles and planes, can provide us with an unparalleled combination of speed and comfort, greatly reducing the time and effort required to reach the destination. Thanks to fast transportation, the geographical barriers have been torn down, people are able to travel on almost any terrain on the earth, whether it is a raging river, rocky mountain or even dense jungle.
现如今，网络和通信技术发展提高了人们获取信息和交流的便利度。网络和通信技术的发展改革了人们沟通和信息分享的方式，世界各地的人们可以利用网络和通信技术进行资源共享或信息沟通。人们可以浏览新闻、快速地进行异地交流、网上消费、休闲娱乐等。过去人们只能靠耗时的书信联系，亲朋好友很久都见不到一面。
Nowadays, the advancement of technology gives rise to a vareity of sophisticated devices which enable people to gain knowledge and information conveniently. The advent of network technology has revolutionized the way people communicate and information-sharing. No matter where friends are, they can be reached at any time via telephone lines or cyber signals. Besides, modern people can browse news, purchase things, exchange ideas, watch movies or videos, and play electronic games online. By contrast, in the past, humans can only contact others mainly by sending them letters, seldom did they meet each other.
医疗技术的发展大大减轻了患者的痛苦、挽救了大量患者的生命，无数患者的生活质量和人均寿命得到了显著的提高。过去很多地方医疗资源严重不足，条件差、设备少，很多患者得不到救治。
Medical techniques are becoming more sophisticated in the present age, which significantly alleviates the suffering of patients and saves lots of lives. Moreover, modern approaches have considerably extended sick persons’ lifespans and maximized their quality of life. By comparison, in the past time, there were insufficient medical resources, poor medical treatment and limited equipments in many areas, numerous patients died because of the lack of efficient treatment.
可以使用的万能切入点还有很多，同学们可以选取自己熟悉的观点展开论证。
通过以上分析，希望能帮助大家在“时间对比”题的审题上有所启发，从而提高该题型的审题效率。
