Read the passage. Write T for true sentences, F for false sentences and N for the sentences containing no information.
It is great to have pen pals. In my opinion, friendship is among the meaningful relations in our life. Many of my friends have pen pals and they correspond regularly. A friend of mine once got a letter from the school mailbox and told me a lot of interesting things about her pen pal. That made me excited and I was eager to have one. Therefore, I got online and did some chatting. I was lucky to get to know a very nice Australian girl. Her name's Jenny. She and I are the same age and we have a lot of things in common.
Although my English was not very good at first, we were able to understand each other quite well. My English has improved a lot. Jenny has never been to Viet Nam. However, she thinks well of our country and our people. When she comes to Viet Nam, I will take her to some interesting places, especially our World Heritage Sites, such as Ha Long Bay, Hoi An Ancient Town, My- Son Tower. Through her mail, she tells me about her country. Thanks to Jenny, I know more and more about Australia. I hope to be an exchange student in Australia some day and we will be able to meet.

I met my best friend when I was small, about 5 years old. It was the first day I went to the kindergarten. I didn't know anyone, I found everything strange and I felt nervous. I went to my class and sat on a desk quietly. A lovely girl came by my side and greeted me. She introduced herself and shook my hands. I found her very sociable and friendly. Since then, we have played, chatted, studied... together. Now, we have been friends for nearly 10 years. We always share every thing together.
