在英语课堂上，学生们可能会用英语来问问题、发言或交流想法。这是因为英语是一种国际语言，在英语课堂上通常是用英语来学习的。下面是一些在英语课堂上常用的英文表达，以及它们的中文意思和一些英文例句：
Can you repeat that, please? （请再重复一遍，好吗？）
I don't understand. （我不明白。）
Can you give an example? （能举个例子吗？）
Can you explain that in more detail? （能详细解释一下吗？）
What does "X" mean? （“X”是什么意思？）
How do you spell "X"? （“X”怎么拼写？）
例如：
Student 1: "I'm not sure I understand what you mean by 'passive voice'."
Student 2: "Can you explain that in more detail?"
Teacher: "Sure. The passive voice is a grammatical construction in which the subject of a sentence is not the doer of the action, but rather the object that the action is being done to. For example, 'The car was hit by a truck.' In this sentence, the car is the subject, but it is not doing the action of being hit. Instead, the action is being done to it. Does that make sense?"
Student 2: "Yes, thank you. That makes more sense now."
