concertina的音標是[?k?ns?te?n?]，意思是“伸縮門；伸縮式掩蔽物；伸縮式折疊門”。

基本翻譯為“伸縮式折疊門”時，可以結合其發音和單詞結構進行記憶。單詞“concertina”由四個部分組成，其中“con”表示“共同”，“cert”表示“確定”，“ina”表示“東西”，結合單詞發音可以聯想記憶為：將門確定（concertina）在一起后，就形成了一個伸縮門（concertina）。

此外，可以使用詞根記憶法來記憶該單詞，即通過單詞“extend”（伸展）變形而來，表示可以伸縮的東西。同時，可以使用詞組“folding concertina”來加強記憶，意為“折疊式伸縮門”。

Concertina，原意為“伸縮門”，其詞源可以追溯到法語詞匯“concert”和“tape”，意為“協調”和“膠帶”。這個詞在英語中用來形容一種可以像拉緊的膠帶一樣折疊或展開的裝置。

變化形式：復數形式為“concertinas”，形容詞形式為“concertinaed”。

The Concertina Effect in Society

In today"s fast-paced society, we are constantly bombarded with new trends, technologies, and ideas. This constant flux creates a kind of concertina effect, where new ideas and information are compressed and released quickly, causing a chain reaction in society.

Take, for example, the rise of social media. It has revolutionized the way we communicate and interact with others, but it has also created a whole new set of challenges and issues. From cyberbullying to fake news, these new trends have had a profound impact on society, causing a chain reaction that has transformed the way we live our lives.

Another example is the rapid adoption of new technologies like artificial intelligence and machine learning. These technologies have the potential to revolutionize many industries, but they also bring with them new concerns about privacy, security, and job displacement. Once again, this rapid adoption has caused a chain reaction in society, with many people feeling overwhelmed and uncertain about the future.

The concertina effect in society is not just about new trends and technologies, however. It is also about social issues like climate change and sustainability. As we strive to address these challenges, we must be mindful of the impact our actions will have on society and future generations. After all, the concertina effect is not just about what is happening now, but also about what will happen in the future.
