how to remember many words

Nowadays, I have got some problems about my vocabulary.
Every day, I get more disunderstanding words. Then how to remember so many words? I really feel confused.

My primary school teacher

Today is special. I talked with my primary scho0l teacher in msn. It is an amazing event for me, may be for everyone if appear. Then it made me thought some events with her.
Although she is my teacher, I regard her as my friend. She is very kind and friendly, also brave. When I was a child, she taught me not only the knowledges of the book but also let me learn a lot of ceremonies and how to communicate with other people. Now, she blessed me all the time beacuse she really was proud of me. Miss Huang, I must be successful, thank you for your helping and teaching.

Expect

There are only two weeks to the final exam, what will happen at that time? I still remember my last presentation, I was really nervous and it made me affort the result.
Three months has gone, I expect what will I express? Can I calm down and take it easy at that time? I hope so.

Post office

I went to post office in March 4th. Not easily, I had got ready for my gift to my girlfriend. I took it to post office happily. You know, I really made the gift box serious. This gift is full of my love. I wish her would be happy.
Finally, with the help of the staff of post office, I wrote the address. I hope my girlfriend would hear from it soon.

ID...

In order to find my ID, I had to get a day-off today. I went out early but the shop still closed. Then I sat and had a breakfast in Mcdonald with my disappointed heart. I was so down.
However, an hour was passed, I could not find my ID yet. Before I restarted to check, I decided to look for it in the shops which I had gone last night.
At last, I went to 3store telephone shop. I saw the seller who introduced me to use the skype card last evening. He put my ID to me.
Oh, thanks!

Sign telephone

I was so excited today beacuse I signed my first telephone in 3store shop.
I spoke a lot with the seller. That was the another thing made me so happy.
But unluckiy, when I came back my room, I found that I lost my ID. What happened?I felt so worried. Most shops had closed. What can I do?

Help

Today is March 1st. Recently, I felt so upset. Many different kinds of things were appeared suddenly, such as study, my travelling visa.
In the study, because the final exam is coming, then the presentation and essay must be got ready from now on. I still remember how toilsome I was in the last term.
Another event is my visa. I wonder to go to Australia to visit my girlfriend after this term. But it has a lot of complicated application that I have to understand it. The complex thing is that I don't have any knowledges on that.
God, help me!
