托福满分作文第一篇


托福满分作文第一篇


拿满分作文都该做些什么呢?

1 看整篇结构,要看一看这些作文的结构是怎么展开的。要仔细的读一下,这些作文每一段的写作目的,到底是支持还是反对,以及哪几段支持,哪几段反对。

2 看段落结构,要仔细分析在一段之中,每一句话所起到的作用。到底是主题句,还是例证。

3 看句型多样性,要仔细想想这些作文每一句话说话的分寸。

4 比对自己的写法。看每一句话的时候,脑中都要思考,这句话中文是什么意思,如果是我自己来写,我会怎么写!并且在下一篇自己的作文中替换为这些用法。

5 用词多样性和准确性。

6 如果有需要的话,再背一下是最好的了,没有输入就没有输出吗!

比如:In this case, computer as a representative of modern technology plays a negative role in learning information. 

这句话,我们自己很有可能写的就是,In this case, computer that is a equipment of modern technology have a bad effect  in learning information.

Does modern technology help students learn more information and learn it more quickly?

 

Marvelous as it looks at first sight, modern technology does not help students learn information at a greater speed and with higher efficiency in most cases; or it could work towards the opposite direction which led students to lose their initiative to learn and explore.

 

First of all, one property of modern technology is latently harmful to any learning mind  it distracts. One thing we feel about when we are searching for information online is that the internet, as an outstanding example of modern technology and even regarded as the innovator of education, provides us with not only relevant results to make use of, but also external links to click. More than once I turned on my computer to check school library for resources, but ended up watching Youtube videos. In this case, computer as a representative of modern technology plays a negative role in learning information. We do acquire more information with the convenient tool, yet most of them are irrelevant and in the end procrastinating would lower our learning.

 

Also, students would easily become disoriented in the huge sea of information. Although modern technology could equip us with easy access to information, the huge amount of resources would actually leave us discombobulated. Therefore, it is only we possess information more quickly rather than we learn it more quickly. An illustrating example is my experience with a HK digital library which stores almost all the books I desire. At first I enjoyed downloading them from the database, however, one month later I ended up with hundreds of books stored in my hardware yet none of them finished or ever clicked.

 

Furthermore, modern technology gives students an illusion that information and real knowledge is easy to learn  just by clicking mouse or watching videos. But in fact this forms only the first step towards useful information and effective learning, as learning of any kind requires full concentration and interactive thinking, which are almost absent in the process of popular e-learning experience.

To summarize, modern technology does not help students learn more information and learn it more quickly, though it does make access to information and resources much more easily. The popular e-learning still lacks the concentration, depth, and interaction that are the hallmark of traditional ways of educating and learning.


基于实时迭代的数值鲁棒NMPC双模稳定预测模型(Matlab代码实现)内容概要:本文介绍了基于实时迭代的数值鲁棒非线性模型预测控制(NMPC)双模稳定预测模型的研究与Matlab代码实现,重点在于提升系统在存在不确定性与扰动情况下的控制性能与稳定性。该模型结合实时迭代优化机制,增强了传统NMPC的数值鲁棒性,并通过双模控制策略兼顾动态响应与稳态精度,适用于复杂非线性系统的预测控制问题。文中还列举了多个相关技术方向的应用案例,涵盖电力系统、路径规划、信号处理、机器学习等多个领域,展示了该方法的广泛适用性与工程价值。; 适合人群:具备一定控制理论基础和Matlab编程能力,从事自动化、电气工程、智能制造、机器人控制等领域研究的研究生、科研人员及工程技术人员。; 使用场景及目标:①应用于非线性系统的高性能预测控制设计,如电力系统调度、无人机控制、机器人轨迹跟踪等;②解决存在模型不确定性、外部扰动下的系统稳定控制问题;③通过Matlab仿真验证控制算法的有效性与鲁棒性,支撑科研论文复现与工程原型开发。; 阅读建议:建议读者结合提供的Matlab代码进行实践,重点关注NMPC的实时迭代机制与双模切换逻辑的设计细节,同时参考文中列举的相关研究方向拓展应用场景,强化对数值鲁棒性与系统稳定性之间平衡的理解。
