Unit 1 The Changing World
Topic 1 Our country has developed rapidly.
Section A 2a-3 and Present Perfect
现在完成时（Present Perfect)
What has he done
He has opened the door.
1.现在完成时的构成
现在完成时的构成由“助动词have/has+动词的过去分词”构成（规则动词的过去分词构成与过去式相同;不规则动词的过去分词见课本P146-148 。)
2.现在完成时的用法：
表示过去发生或已经完成的某一动作对现在造成的影响或结果（用法之一）
3.现在完成时与一般过去时的区别：
What did he do just now
He opened the door just now.
现在完成时表示过去发生或已经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某一时间的时间状语连用，如：yesterday,just now, in 2015,two days age等。而一般过去时只表示过去的动作或状态，和现在不发生联系。强调的是过去的情况，它可以和表示过去某一时间的时间状语连用。
