copepoda音標(biāo)為["k??p??d?]（發(fā)音時(shí)注意："的發(fā)音為/??/），意思是甲殼動(dòng)物門中尾下綱的統(tǒng)稱。

速記技巧：可以將這個(gè)單詞分解為“cop”（表示“警察”）和“pod”（表示“球”）兩個(gè)部分，從而記住它是由警察和球組成的。

基本翻譯：尾下綱是甲殼動(dòng)物門中的一個(gè)綱，其特點(diǎn)是具有一對尾肢，位于身體末端的下方。在copepoda中，這個(gè)綱包括了許多重要的海洋生物，如龍蝦、螃蟹等。

Copepods是節(jié)肢動(dòng)物門甲殼動(dòng)物綱的橈足類，英文詞源可能來自拉丁語“corpus”（身體）和“opep”（足）的組合，意為“身體上的足”。

變化形式：復(fù)數(shù)形式為copepods，過去式為copi，過去分詞為copied。

相關(guān)單詞：

1. copepodite：橈足類幼體，指橈足類幼體。

2. copepodometry：橈足類測量學(xué)，研究橈足類的測量和分類。

3. copepodid：橈足類幼體之一，是橈足類中最小的一種。

4. copepodite-larva：橈足類幼體-幼體，指橈足類幼體和幼體的統(tǒng)稱。

5. copepodite-larvae：橈足類幼體群，指橈足類幼體和幼體的總稱。

6. copepod-like：類似橈足類的，指形態(tài)上與橈足類相似的生物。

7. copepod-like organism：類似橈足類的生物，指形態(tài)上與橈足類相似的生物體。

8. copepod-like animal：類似橈足類的動(dòng)物，指形態(tài)上與橈足類相似的動(dòng)物。

9. copepod-like creature：類似橈足類的生物體，指形態(tài)上與橈足類相似的生物。

10. copepod-like species：類似橈足類的物種，指形態(tài)上與橈足類相似的物種。

總之，Copepods作為橈足類的英文名稱，其詞源來自拉丁語“corpus”和“opep”，變化形式包括復(fù)數(shù)、過去式和過去分詞等。相關(guān)單詞包括其幼體、幼體群、類似生物、類似動(dòng)物等，這些單詞在生物學(xué)和生態(tài)學(xué)領(lǐng)域都有廣泛的應(yīng)用。

英文小作文：

Copepods are tiny marine animals that play a crucial role in the ocean"s food web. They are an essential component of the marine ecosystem, providing food for many species of fish and other marine animals. However, climate change is affecting their reproduction rate and feeding habits, leading to changes in the ocean"s ecosystem. Understanding these changes and how they affect marine life is crucial for ensuring a sustainable future for our oceans.

Copepods are small, but they have a significant impact on the ocean"s ecosystem. They are an essential link in the food chain, providing food for larger predators and playing a crucial role in maintaining the balance of the ecosystem. However, as the climate changes, these tiny animals are facing new challenges and pressures that could affect their survival and the health of the ocean"s ecosystems. It is our responsibility to understand these changes and take action to protect these important species and the environment they depend on.
