apprehensiveness的音標(biāo)是[??prenh?ns?v?s]，基本翻譯是“理解力；理解能力；憂慮”。

速記技巧是：可以通過發(fā)音相似的單詞來記憶，例如使用“阿婆肉粉絲”來記憶這個(gè)單詞。此外，也可以通過詞根詞綴來記憶，例如在英語中表示“理解”的詞根有“per-”和“comprehend”。

Apprehensiveness這個(gè)詞表示的是一種對(duì)未知事物或可能出現(xiàn)的危險(xiǎn)或挑戰(zhàn)的擔(dān)憂和恐懼。這個(gè)詞的詞源可以追溯到拉丁語“aprehendere”，意為“抓住，理解”。

這個(gè)詞的變化形式包括：

1. apprehension - 擔(dān)憂，理解

2. apprehensive - 擔(dān)憂的，敏感的

3. prehend - 抓住，捕獲

4. prehensive - 具有抓住能力的

5. overtake - 突然出現(xiàn)，襲擊

6. alarm - 警報(bào)，驚慌

7. dread - 恐懼，害怕

8. fear - 害怕，恐懼

9. timidity - 膽小，怯懦

10. skittish - 易受驚的，不安定的

對(duì)于相關(guān)單詞的解釋：這些變化形式和相關(guān)單詞都反映了apprehensiveness的基本含義，即對(duì)未知事物的擔(dān)憂和恐懼。這些單詞在英語中經(jīng)常用來描述人的情緒狀態(tài)，或者用來描述某種情境下的行為或反應(yīng)。例如，“alarm”可以用來描述對(duì)危險(xiǎn)或緊急情況的擔(dān)憂，“fear”可以用來描述對(duì)某種特定情況的恐懼。這些單詞在英語中非常常見，而且經(jīng)常在各種語境中使用。
