Yes, he has cleaned it _.A. just, yet B. already, just C. just, already D. / , already此题应该选用D项。前面为疑问句，不可以用“ just/already”提问，故A/B/C项都是错误的，后面是肯定结构，故应该用“already”。3、Jim, have you had your lunch _ ? Its only 10:30 in the morning .A. yet B. just now C. just D. already 此题应该选用D项。前面为疑问句，但是从“Its only 10:30 in the morning .”中可以看出问话人非常惊讶，故应该用“already”连接。4、Ive _ found my lost pen. I found it under my desk _.A. just, just B. just now, just now C. just, just now D. just now, just 此题应该选用C项。前面为完成时态，后面为过去时态，故应该用“just/ just now”分别连接，“just now”意为“ a moment ago”。（四）巩固拓展中考英语总复习教案二十二语法重点：现在完成时态 (Present Perfect Tense) (二)难点突破：(1)ever与never、 (2)have/has been to与 /have/ has gone to的区别使用知识目标：通过操练、专项练习等方式复习“现在完成时态”的时态结构以及相关用法。复习步骤设计：（一）词汇复习Revision of the words and phrases learnt in Unit Two, dictation of some main words and phrases learnt in this unit（此环节也可根据中考词汇表顺序进行听写检查）。（二）对话操练（Dialogue Actingask Ss to act out some dialogues about Have you ever been to Harbin?
