1、题目大意
一些人认为很多日前的科学实验是浪费时间和金钱。你是否同意？
2、思路解析
这是一道观点类大作文，聊的是科学实验是否是浪费时间和金钱。题目就一句话，理解起来其实不难，审题时可以注意两点，一是“scientific research”本身的特性需要考虑，二是“a lot of”是一个模糊的概念，可以进行反驳。下面月半鸭和大家一起来看下具体观点。
首先来看同意的角度。许多科学实验确实耗费巨大，需要数百亿的资金以及几年甚至十几年的时间投入并且无法保证最终的成功，同时很多实验还是在对同一个主题进行的重复研究。这样的重复投入和失败结果往往被人认作是一种浪费，何况这些巨额资金如果能用于解决贫困、饥饿等方面可以更好的改善人们生活。
然后再来看反对角度，有三方面。
一是“大量”这个数字过于抽象，大众所能了解到的往往并非事实全部，而只是被媒体或一些渠道展现出来的那一部分，并且我们也难以在最终结果出来前去判断这个实验是否成功。
二是重复实验本身是科学研究的一个必要过程，只有当一个结果是能被多次反复的得出，我们才能认为这个结果为“真”，并将此运用到现实中或者展开进一步研究。
三是有些实验虽然会失败，但是科学实验本身就存在“证伪”的目的性，一个失败结果代表在科学研究上排除了一个错误方向，也就意味着科学家离成功可能更进了一步，因此这些失败的实验都是具有价值的。
3、提纲
4、高分范文示例
Over the past few decades, significant technological advancements have brought about remarkable transformations. While scientific experiments often require sizeable financial investments, some individuals argue that such endeavors are futile and a waste of resources. I, however, strongly disagree with this viewpoint.
Initially, the manuscript's title is subjective, as the term "a lot" cannot be quantified precisely. An overemphasis on a limited number of adverse incidents reported in the media may be blamed for the generally held belief that scientific experimentation failure is common. Secondly, persons who hold this position appear to have an inadequate understanding of the fundamental nature of scientific experimentation and science as a whole. It is imperative to note that scientific theories are falsifiable, meaning that they can be replaced with new theories based on the results of repeated attempts via diverse categories of research. Therefore, "failure" is an inherent component of the scientific process. Moreover, the early investments and sacrifices made for previous theories serve as the basis for future breakthroughs, even if they are not immediately acknowledged or appreciated by future generations.
Undoubtedly, due to limitations in technology and funding, certain short-term scientific research may appear to lack clear objectives and offer no direct benefits to society. Critics may label such research as a form of "waste." However, abandoning such experiments would have severe consequences. For instance, with the current global pandemic, major labour and material resources are being allocated to vaccine research for COVID-19. Thus far, no country has succeeded, but this does not necessarily imply the initial investment was futile. Discontinuing relevant scientific research would cause the loss of public faith in defeating the virus, resulting in unprecedented disasters.
In conclusion, despite the reality that many experiments fail in the modern world, unsuccessful research may mark the origin of a groundbreaking discovery. Therefore, they should never be considered "waste".
