Couldn't意思
"Couldn't" 是 "could not" 的縮寫,意思是「不能」、「無法」。在英語中,它通常用來表達某人沒有能力、許可權或機會去做某事。例如:
- I couldn't understand the lecture because it was too technical. (我無法理解講座,因為它太專業了。)
- She couldn't attend the meeting due to illness. (由於生病,她無法參加會議。)
- We couldn't finish the project on time because of the lack of resources. (由於缺乏資源,我們無法按時完成項目。)
在口語中,"couldn't" 也可以用來表示強烈的否定或強調,類似於 "not at all" 或 "not possible" 的意思。例如:
- I couldn't disagree more. (我完全不同意。)
- She couldn't have been more wrong. (她不可能更錯了。)
注意,"couldn't" 是情態動詞 "could" 的否定形式,用於過去時態。如果你想表達的是現在或將來時態的否定,你需要使用相應的時態形式。例如:
- I can't understand this concept. (我現在無法理解這個概念。)
- She won't be able to attend the party. (她將無法參加聚會。)
