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,in2002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.

My online trip to Sydney
I learned about Sydney in my Geography lesson. I got very interested and decided to explore it online.
Sydney is an amazing city on the south - east coast of Australia. It is well known for its beautiful beaches and the Sydney Opera House, which looks like a sailing boat.
I "visited" the Sydney Opera House first. I could zoom in to see the unique design of its roof. Then I "went" to Bondi Beach. I saw people surfing. There were also interesting introductions to these places, so it was easy to learn more about them.
Thanks to the internet, I can visit Sydney without leaving home. The pictures and videos were wonderful. I felt like I was walking on the streets of Sydney. Moreover, I didn't need to worry about the weather, and it cost nothing. This online trip was really great!
Thanks!
