Dear Alice,
I haven't talked to you for a long time. How are you doing now? I'm free now so I'm writing this letter to tell you about my free time.
I usually surfing the Internet on my free time. I have plenty of favorite websites and I also write lots of emails. Generally speaking, I see the internet as a good thing. In addition, I enjoy watching movies. I watching comedy and cartoon because it's make me feel funny and relaxed. Finally, what I to do in my free time is listening to music. I prefer pop music most. However, I also enjoy listening to rock music and sometimes classic music, it depends on my mood.
What about you? What do you do in your free time? Write me soon.
Best wishes,
Duong

I. Read the passage and write T or F
The second Sunday in May is Mother’s Day. It is a public holiday in both Britain and America. On that day, children send Mother’s Day cards to their mothers. They give their mothers flowers or sweets as presents. Fathers and children do the cooking so that mothers can have a rest.
In the USA, Mother’s Day started in 1860s.. There was a small town called Pruntytown in the middle of the USA. People in the town fought against each other during a war. After the war, they hated each other. Mrs Ann Reeves Janis wanted the people to make friends with each other again. So she started “Mother’s Friendship Day”. On that day, she visited all the other mothers in the town and said, “Let us be friends with each other again”.
Her idea succeeded. The same thing happened in other parts of the country. After she died, her daughter carried on her idea. In 1908, “Mother’s Friendship Day” became “Mother’s Day”.
