1、題目大意

一些人認為(wei) 很多日前的科學實驗是浪費時間和金錢。你是否同意？

2、思路解析

這是一道觀點類大作文，聊的是科學實驗是否是浪費時間和金錢。題目就一句話，理解起來其實不難，審題時可以注意兩(liang) 點，一是“scientific research”本身的特性需要考慮，二是“a lot of”是一個(ge) 模糊的概念，可以進行反駁。下麵月半鴨和大家一起來看下具體(ti) 觀點。

首先來看同意的角度。許多科學實驗確實耗費巨大，需要數百億(yi) 的資金以及幾年甚至十幾年的時間投入並且無法保證最終的成功，同時很多實驗還是在對同一個(ge) 主題進行的重複研究。這樣的重複投入和失敗結果往往被人認作是一種浪費，何況這些巨額資金如果能用於(yu) 解決(jue) 貧困、饑餓等方麵可以更好的改善人們(men) 生活。

然後再來看反對角度，有三方麵。

一是“大量”這個(ge) 數字過於(yu) 抽象，大眾(zhong) 所能了解到的往往並非事實全部，而隻是被媒體(ti) 或一些渠道展現出來的那一部分，並且我們(men) 也難以在最終結果出來前去判斷這個(ge) 實驗是否成功。

二是重複實驗本身是科學研究的一個(ge) 必要過程，隻有當一個(ge) 結果是能被多次反複的得出，我們(men) 才能認為(wei) 這個(ge) 結果為(wei) “真”，並將此運用到現實中或者展開進一步研究。

三是有些實驗雖然會(hui) 失敗，但是科學實驗本身就存在“證偽(wei) ”的目的性，一個(ge) 失敗結果代表在科學研究上排除了一個(ge) 錯誤方向，也就意味著科學家離成功可能更進了一步，因此這些失敗的實驗都是具有價(jia) 值的。

3、提綱

4、高分範文示例

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".
