在现在完成时中 ever never just already yet在用法和意思上有什么区别?
太长了拉 在说我问的好象不是这个啊

现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果.如:
Have you read that story?你读过那个故事吗?(“读”这一动作发生在过去,对现在造成的影响是:是否知道故事的内容.)
I have bought two apples. 我买了两个苹果.(“买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果.)
在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already,just,ever,yet,never等.already,just多用于肯定句中,ever,yet,never多用于疑问句和否定句中.如:
I have already finished my homework.我已经做完家庭作业了.
He has just had his meal.他刚吃过饭.
Have you ever sung this English song?你曾唱过这首英文歌吗?
They haven't started yet.他们还没有动身.
We have never heard of it.我们从来没有听说过这件事.
现在完成时表示过去的动作对现在造成的影响;一般过去时表示动作发生的时间在过去.试比较:
The plane has arrived .飞机已经来了.(说明现在的情况:飞机在这儿.)
The plane arrived a quarter of an hour ago.飞机是一刻钟以前抵达的.(强调动作发生的时间在过去.)
have been in,have been to 与have gone to 的用法
1.have(has) been in 意为“已经在某地呆了多长时间”,常与表示一段时间的状语连用.如:
Mr.Brown has been in Shanghai for three days.布朗先生来上海已经有三天了.
They have been in Canada for five years.他们到加拿大有五年了.
2.have(has) been to意为“曾经去过某地”,表示现在已经不在那里了.可与just,ever,never等连用.如:
I've just been to the post office.我刚才去邮局了.
Have you ever been to Hangzhou?你曾经去过杭州吗?
Mary has never been to the Great Wall.玛丽从未去过长城.
3.have(has) been to 后面可接次数,表示去过某地几次.如:
I've been to Beijing three times.我去过北京三次.
They have been to that village several times.他们去过那个村庄好几次了.
4.have(has) gone to 意为“到某地去了”,表示到了某地或正在去某地的途中.总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语.如:
