blockers的音標為[?bl?k?z] ，基本翻譯為“阻止器；阻擋物；阻礙物”。速記技巧為：使用元音字母組合ea快速記憶。

Blockers 的英文詞源是來自古英語 bloca，意為“阻止，阻礙”。它的變化形式包括過去式 blocked，過去分詞 blocked，現在分詞 blocking。

相關單詞：

blockade：n. 封鎖；阻止；障礙

obstacle：n. 障礙；阻擋物；困難

blockade：n. 封鎖；阻止；障礙物

blocking：n. 阻止；阻礙

blockish：adj. 愚蠢的；頑固的；阻礙的

這些單詞都與 blockers 有著相似的含義，表示阻礙、阻止或妨礙事物的發展或進程。例如，在軍事行動中，blockade 通常指的是對敵方領土或交通線的封鎖，以阻止敵方的行動或物資運輸。同時，obstacle 和 blockade 也常用于描述生活中的困難和挑戰。

英文小作文：

Blockers are essential components in electronic circuits, which can protect circuits from damage caused by excessive current or voltage. Without blockers, electronic circuits may be damaged easily, leading to malfunction or even failure. Blockers can be used in various forms, such as resistors, transistors, and layers in the circuit board, to provide effective protection for electronic circuits. In addition, blockers also play an important role in ensuring the stability and efficiency of electronic devices, such as batteries and cells. Without blockers, these devices may suffer from performance degradation or even failure due to excessive discharge or current flow. Therefore, blockers are crucial components in ensuring the reliability and stability of electronic systems.
