covalent的音标为[kəʊ"vælənt],基本翻译为“共价键的;共价结合的”。
速记技巧:可以将单词拆分为“co-”和“valent”两个部分,“co-”意为“共同”,“valent”意为“有吸引力的”,整体含义为“共同有吸引力的”,即“共价键的;共价结合的”。
Covalent这个词来源于拉丁语,意思是“共价的”。它的变化形式包括名词covalence和形容词covalent。

英文小作文:
Covalent bonds are essential for the stability and function of chemical compounds, which are crucial for life on Earth. From DNA to polymers, covalent bonds play a vital role in the chemical processes that occur within our bodies and the environment around us. Understanding covalent bonding is fundamental to understanding the world around us, and it is essential for chemists, biologists, and other scientists who work in the field of chemistry and biology. However, covalent bonds are not just important for science; they also have practical applications in technology and industry, such as in the production of polymers and other materials that are used in daily life. Therefore, covalent bonds are not only fundamental to understanding the world around us, but they also have practical applications in our daily lives.
