chemical element

chemical element的音标是[ˌkemɪkl ˈeləmənt]，基本翻译是“化学元素”。

记忆技巧：这个单词是由两个词组成的，chemical（化学的）和element（元素）。可以尝试将这个单词分解成更小的部分来帮助记忆，例如“chemi-cel-ment”或者“chemi-el-ment”。此外，可以尝试将这个单词与一个熟悉的单词联系起来，例如“化学元素周期表”或者“化学元素周期的元素”。

希望以上信息对您有帮助。建议查阅英文词典以获得更精准的含义。

以下是一些化学元素的英文词源、变化形式及相关单词：

1. Hydrogen (氢)：词源为拉丁语“水”，因为氢是最轻的气体，在高压下可以像水一样存在。变化形式：deuterium (重氢)、tritium (超重氢)。相关单词：hydrogenation (氢化)，指用氢使不饱和化合物变得饱和的过程。

2. Oxygen (氧)：词源为希腊语“oxys”和“genes”，意为“气”和“产生”，因为氧是生物体内重要的呼吸元素。变化形式：deoxyribonucleic acid (脱氧核糖核酸)，简称DNA。相关单词：respiration (呼吸)，oxygenator (氧合器)，指使血液中的红细胞与氧结合的设备。

3. Carbon (碳)：词源为拉丁语“carbo”，意为“木炭”，因为碳是最常见的元素之一，通常以石墨或金刚石的形式存在。变化形式：carbide (碳化物)，如 cement carbide (金刚石碳化硅)。相关单词：carbonization (碳化)，指将金属转化为碳化物的过程。

4. Nitrogen (氮)：词源为拉丁语“nebulo”，意为“云”，因为氮是空气中最丰富的元素。变化形式：dinitrogen (氮气)，nitrate (硝酸盐)。相关单词：denitrogenation (脱氮)，指从生物组织中去除氮的过程。

5. Fluorine (氟)：词源为拉丁语“fluere”，意为“流动”，因为氟是一种非常活泼的元素，可以与许多其他元素形成化合物。变化形式：fluoro- (氟-)，如 fluorite (萤石)。相关单词：fluoroscopy (荧光透视)，利用荧光物质显示氟的存在。

以上元素的英文名称在英语中具有丰富的词源和变化形式，并且与许多相关的科学和工业术语密切相关。这些元素在化学、生物学、医学和工业领域中具有广泛的应用，对于人类的生活和生产具有重要意义。

英文小作文：

Chemical elements play a vital role in our daily lives, from the food we eat to the materials we use to build our homes and vehicles. From oxygen, which is essential for life, to iron, which is used in many tools and machines, chemical elements are everywhere and have had a profound impact on human society.

On a daily basis, we use chemical elements in various ways. For instance, we use oxygen to breathe, carbon to make paper and plastic, and nitrogen to make fertilizers and medicines. These elements are essential for the production of many products that we use every day, such as clothing, food, and building materials.

Moreover, chemical elements are also crucial for scientific research and technological development. Understanding the properties of different chemical elements allows scientists to create new materials and develop advanced technologies that are not possible without them. For instance, advances in quantum computing and nanotechnology have been made possible by the study of chemical elements and their properties.

In conclusion, chemical elements are essential for our daily lives and for the advancement of science and technology. Without them, our world would be very different and much more difficult to survive and thrive in.
