The blackboard is so clean now. He has already cleaned the blackboard. 这句话所表示强调的结果是黑板现在是干净的。(他已经擦过黑板了。)现在完成时的时间副词和时间短语:1)副词already和yet。already一般用于肯定句中，yet一般用于否定句和疑问句中。 e.g. We have already finished our homework. 2)副词ever 和never。多用于否定或疑问句中，表示“曾经”或“从未“等。e.g. Have you ever been to the Great Wall? 你曾经去过长城吗?3)用just表示到说话时为止的时间状语, e.g. I have just seen her, but I dont know where she is now .注意：当在肯定陈述句中含有already或just 时，在转换成否定句或疑问句时，要把句中的already 或just 去掉，在句末加上yet. e.g. I have done my homework already.

A. lose B. to lose C. lost D. losing解析 答案为C。 本题主要考查现在完成时态对谓语动词的要求。现在完成时态谓语动词的结构是have (has)+ 过去分词。 本题空白处需要过去分词，这样A、B、D都不对。2) 误：The twins have not got home already.正：The twins have not got home yet.解析：本题主要考查yet 与 already的用法区别，两个词都是副词，常与完成时态连用。yet 用于否定句和疑问句，提通常置于句尾；already 常用于肯定句，当用于疑问句时，表示惊讶或希望得到肯定的答复，不用于否定句中，它可以在主要动词之前，也可置于句末。3)Jim has been at the factory_ two years ago.A. for B. since C. before D. after解析：答案为B。 本题主要考查时间状语与谓语的关系。for后跟时间段表示一段时间,since 后跟时间段+ago，表示一段时间,before 表示在什么时间之前,after则表示在什么时间之后。本句是完成时态，指自两年前以来如何，且两年前是个时间的（起）点，因此，此处应用since.4)误:I saw the film twice already.正:Ive seen the film twice already.解析； 本题主要是一般过去时态与现在完成时态的概念错误。这电影我已看过两遍，说明我现在对电影内容很了解，故要用现在完成时态。5)_you _ your watch?- no,_.A. Did, find out, I didnt B. Have, found, not yetC. Have, looked for, I havent D. did, find, not yet答案选“B”。全句应用现在完成时，强调到现在为止的情况“是否找到了手表”，答语；Not yet 相当于说 I havent found it yet.6)I have never seen the film _.A. ago B. just now C. before D. later答案选“C”。 动词时态为现在完成时，与之搭配的词必须是Ever, never, already, yet, before, recently 等词。而 ago, just now 等只能用于一般过去时句子中，用later意思不通【专项练习】一、单项选择题1.Howlonghaveyou_here?
