(我们已经学习了第二单元。)She is the most beautiful girl I have ever seen. (她是我见过的最漂亮的女孩。)而现在完成进行时则表示的是从过去某一时刻开始一直延续到现在，并且还要进行下去的动作，具有未完成的特点，一般不与already或ever等连用，如：We have been learning Unit 2. 我们一直在学习第二单元。（没学完）注意以下两组句子含义上的区别：I have read the novel. 我看过那本书了. (已看完)I have been reading the novel. (一直在看，还没有看完)Who has eaten my dinner? （表示“全吃光了”）Who has been eating my dinner? （表示“还有一些剩下”）第二，相对于现在完成时表示次性，现在完成进行时可以表示动作的重复，请看以下句子：I have met him at the library. (我在图书馆见过他。)I have been meeting him at the library. (我经常在图书馆看见她。)第三，现在完成时和现在完成进行时都可以表示刚刚结束的动作，但在含义上有区别。现在完成时强调的是动作的结果，而现在完成进行时强调的则是动作的过程。如：You look so tired, what have you been doing?你看起来很累，做什么了？（强调动作）We are very tired. Weve been cleaning the house.我们很累，我们刚才在打扫房子。（强调该动作所导致）Weve cleaned the house. You may come in now.我们打扫过房子了，你可以进来了。（强调结果“房子干净”）（三）对应训练 用适当的时态填空： 1.
