delineated的音標(biāo)為[d??l?ne?t?d]，基本翻譯為“詳述的；輪廓分明的；劃清界線的”。

速記技巧：可以嘗試使用音節(jié)拼讀法來記憶這個(gè)單詞，即“de-line-a-ted”，其中“l(fā)ine”的意思是“線條”，“-ted”是過去分詞的詞尾。通過這種方式，可以更快速地回憶起這個(gè)單詞的拼寫。

delineated的英文詞源為：拉丁語delaere，意為to draw，draw out，以及l(fā)inea，意為line。

delineated的變化形式有：過去式delineated，過去分詞delineated，現(xiàn)在分詞delineating，以及其名詞形式delineation。

這些單詞在句子中可以充當(dāng)名詞、形容詞、動(dòng)詞等不同的詞性，表達(dá)不同的意思。例如，在“The outline of the building was delineated with chalk”這句話中，delineated是形容詞，表示用粉筆描繪出建筑物的輪廓。而在“The design was delineated with great care and precision”這句話中，delineation是名詞，表示精心細(xì)致地描繪出的設(shè)計(jì)。

總之，delineated作為形容詞和名詞，在英語中常用于描繪、繪制相關(guān)的事物或概念。

英文小作文：

The importance of boundaries

Boundaries are essential in maintaining personal and social well-being. They define our space, protect our privacy, and help us to maintain healthy relationships with others. When boundaries are not clearly delineated, we may find ourselves constantly being pushed and pulled, leading to feelings of stress and anxiety. Conversely, when boundaries are respected and followed, we can feel more secure and in control of our lives. Therefore, it is important to carefully delineate our boundaries and communicate them clearly to others, so that we can maintain healthy relationships and avoid unnecessary conflicts.
