close in on的音標(biāo)是[kl??s ?n ?ɑ?n]，基本翻譯是“逼近，接近”，速記技巧是“close”緊閉，“in”里面，“on”在上面。

Close in on的英文詞源為：

- close：來自古英語 clāwian，意為“關(guān)閉，封閉”。

- in：表示“向……內(nèi)，在……里面”。

- on：表示“靠近，接近”。

變化形式：

- 比較級(jí)：closer或closer in。

- 最高級(jí)：closest。

相關(guān)單詞：

- approach：意為“接近，靠近”，其詞源與close in on同源，都含有逐漸接近的意思。

- corridor：意為“走廊”，corridor這個(gè)詞源于拉丁語corridus，原意是“圍繞的通道”。

- enclose：意為“包圍”，其詞源與close in on同源，都含有將某物圍住的意思。

舉例來說，當(dāng)描述一個(gè)物體逐漸靠近另一個(gè)物體時(shí)，我們可以用close in on這個(gè)詞組。此外，在軍事行動(dòng)中，我們也可以使用這個(gè)詞組來表示逐漸包圍敵方陣地。這個(gè)詞組的使用范圍非常廣泛，可以用于描述各種情況下的逐漸接近或包圍。

英文小作文：

The End of an Era

As I look back on my childhood, I realize that a time has come to say goodbye to an era. I remember those carefree days when I was young, playing with my friends in the park, laughing and singing together. Those memories are precious and I will never forget them. However, now it"s time to move on and embrace a new era. I must not close the book on my past, but rather embrace it as a part of my history and use it as motivation to move forward. As I grow up, I will face new challenges and opportunities, and I will learn to adapt and overcome them. I will not be afraid of change, because it is what makes us stronger and more resilient. So, as I say goodbye to one era and embrace another, I will remember the past with gratitude and hope for the future with courage and optimism.
