What have yu read recently, Fu Xing?
—Have yu read Arund the Wrld in Eighty Days, Adam? —Yes, I have. / N, I haven’t.
I’ve already finished reading the bk!
① Silvia has bught a new dress, but she hasn’t wrn it yet.② —Have yu read the bk yet, Harry? —Yes, I have.
1.already表示“已经”，强调动作的完成，常用于肯定句中。
2.yet常用在否定句中, 表示“尚未, 还未”，用在疑问句中表示“已经”。
注意：already一般置于助动词 have/has之后，过去分词之前。
注意：yet一般置于否定句或疑问句的结尾处。
3.ever 表示 “曾经”，主要用于疑问句。
—Have yu ever been t a science museum?—Yes, I have.
Let’s g t the space museum. I’ve never been there.
4.never 表示 “从来没有，从不”，表示否定。
注意：never, ever一般置于助动词，have/has之后，过去分词之前。
5.just 强调动作 “刚刚(不久前)完成”, 突出动作发生的时间离现在非常近，常位于 “have/has” 之后。
I have just finished my hmewrk.
现在完成时副词口诀:曾经ever从未never，疑问否定中间歇；刚刚just已经already，肯定句中中间待；还没yet句末站，否定疑问都能看。
