aggregate demand音標(biāo)為["?gr?g?d?m] ，基本翻譯為“總需求”，速記技巧為：aggregate（總）＋ demand（需求）。

Aggregate demand這個詞的詞源可以追溯到拉丁語“aggreagere”，意為“聚集”或“集合”。它通常用來描述經(jīng)濟體中對商品和服務(wù)的需求的總和。

變化形式：在英語中，aggregate一詞的基本形式是“aggregate”，而demand則保持不變。

相關(guān)單詞：

1. Aggregate supply（總供給）：這個術(shù)語通常與aggregate demand一起使用，用來描述經(jīng)濟體中所有生產(chǎn)要素對商品和服務(wù)的供給的總和。

2. Subsistence demand（生存需求）：這個詞用來描述維持生存所需的基本需求，比如食物和住所。

3. Peak aggregate demand（總需求峰值）：這個詞用來描述在總需求達到最高點時的狀態(tài)，通常在經(jīng)濟學(xué)中用來預(yù)測經(jīng)濟衰退的可能性。

4. Non-aggregate demand（非聚集需求）：這個詞用來描述那些不能被直接分割成更小的部分的需求，比如服務(wù)需求。

5. Demand elasticity（需求彈性）：這個詞用來描述需求對價格或其他因素變化的反應(yīng)程度，是經(jīng)濟學(xué)中的一個重要概念。

以上這些單詞都與aggregate demand有著密切的聯(lián)系，它們幫助我們更好地理解經(jīng)濟體中的需求動態(tài)。

英文小作文：

Aggregate demand is the total amount of goods and services that consumers are willing to buy at a given price level. It is influenced by many factors, including government policies, economic conditions, and consumer behavior. When aggregate demand increases, prices tend to rise and production expands. Conversely, when aggregate demand falls, prices tend to fall and production contracts. Understanding aggregate demand is crucial for forecasting economic trends and formulating effective policy measures.
