2. 现在完成时与一般过去时的区别：
现在完成时表示某一已完成的动作对现在造成的影响或结果，强调的是现在的情况，所以它不能和表示过去的时间状语连用；而一般过去时只单纯表示过去的动作或状态，和现在没有联系，它可以和表示过去的时间状语连用。例如：
I bought a CD player last week. 我上周买了一台CD机。(只说明买CD机这个事情发生在上周)
I have bought a CD player. 我买了一台CD机了。(言下之意是我现在有了一台CD机)
现在完成时用来表示过去发生的动作或状态对现在产生的影响和结果，汉语中常用“已”或“已经”来表达“已完成”这个意义。其构成为“has/have+动词的过去分词”，其中has用于第三人称单数。规则动词过去分词的构成和它的过去式是一样的，第12册Grammar Notes的Unit 13 中已经对此作了详尽的介绍，这里不再讲解。常见的不规则动词的过去分词的变化形式请参照书后附录的Irregular Verbs。
1. 现在完成时的句子中经常要用到just、already、never、ever、yet等这些副词，具体用法如下：
(1)just(刚刚)常用于肯定句中，放在has/have后，表示刚刚发生的动作。例如：
He has just left.他刚走。
(2)already(已经)用于肯定句中，放在has/have之后，或者出现在句末。例如：
We have already finished it. / We have finished it already.我们已经完成了。
(3)ever(曾经)用于疑问句中，用于询问某人过去的经历。例如：
Have you ever been to the Great Wall? 你去过长城吗？
(4)never(从来没有)表示否定，放在has/have后。例如
He has never visited the Great Wall.他从没去过长城。
(5)yet(仍然，还)用于疑问句或否定句中，放在句末。例如：
Have you finished your homework yet? 你完成作业了吗？
No, I haven’t yet.不，还没呢。
