语法+写作解析
一、语法解析
一般过去时与现在完成时的区别
(一)侧重点不同
一般过去时表示过去某个时间发生的事，存在的状态或经常发生的动作，说话的侧重点只在于陈述一件过去的事情，不强调对“现在"产生的影响。
现在完成时表示动作发生在过去，对现在造成影响或产生了结果。
Eg: We cleaned the classroom this morning.
今天早上我们打扫了教室。(教室是今天早上打扫的，至于现在是否干净，无从得知)
We have already cleaned the classroom.
我们已经打扫了教室。(心在教室是干净的)
(二)构成方式不同
一般过去时:主语+动词过去式+其它
现在完成时:主语+have/has+动词过去分词+其它
Eg: He saw her three days ago.
三天前他看见她了。
I have already finished my homework.
我已经完成我的家庭作业了。
(三)时间状语不同
一般过去时:yesterday, last week, two years ago, just now, in 2002等
现在完成时:just,already,ever,never,these days, this week, since...,for...等连用
Eg: Did you see the film last night
你昨晚看那部电影了吗
He has lived in Beijing for 8 years.

How time flies! I have changed a lot in the past two years. I can't wait to share my changes with you, which have a great influence on my study and life.
Looking back to the eighth grade, I used to be short and thin. But now I'm much taller and stronger by doing exercise. Besides, I used to be shy and silent. I wasn't brave enough to speak in front of crowds. But now I'm more outgoing and dare to give a speech in public. What's more, I used to be weak in English. Thanks to my teacher, she advised me to
listen carefully in class and read notes after class. As a result, I make great progress in English and get good grades.
From my experiences, I realized that changes bring challenges as well as opportunities. Remember, it's never too late to make changes to be a better person.
Thanks!
