✔ 最佳答案
already(已經)和 not... yet (還沒)常常放在完成式 , 而且already用在"肯定句"yet常配合"否定句"和"疑問句"使用 , 舉例如下 :1. He has already eaten an apple . = He has eaten the apple already .= He has eaten the apple . ( already 可放句中,句尾 , 或省略 )2. Have you eaten your dinner yet ? (yet 放疑問句 )答句可答 : Not yet . (還沒)3. No, I haven't eaten my dinner yet . (not ...yet 還沒 )4. Summer vacation has not ended (yet) . = Summer vacation has not (yet) ended . (yet 也可省略 ) 注意 : 很多人都以為 already ,yet 只能放在完成式 , 那是錯的喔 !already 也可以放在一般式例如 : It is already eleven o'clock .(已經11點了)It's not twelve o'clock yet .(還沒12點) 而just 可解釋為 : (1) 剛才,剛剛 ----- 用於完成式則放在完成式公式中間Tommy has just finished the homework .(2) 就 , 只是 ----- 放在 be 動詞之後 , 一般動詞之前I just want you to finish the homework .Sally is just a little girl .
