【study第三人称单数】在英语语法中,动词的时态和人称变化是学习者容易混淆的部分之一。其中,“study”是一个常见的动词,表示“学习”或“研究”。当它用于第三人称单数(即he, she, it)时,需要根据时态进行相应的变形。
以下是“study”在不同人称和时态下的正确形式总结:
一、
“Study”作为动词,在一般现在时中,当主语是第三人称单数(如he, she, it)时,动词需要加“-s”或“-es”后缀。例如,“He studies English every day.”
此外,其他时态中的“study”也会根据主语和时态的不同而变化,如过去式“studied”,现在分词“studying”,过去分词“studied”等。
为了帮助学习者更好地掌握“study”的用法,下面列出其在不同人称和时态下的形式,并附上例句说明。
