读一读Tom的日记，根据日记内容，选择正确的答案。

June 8, Friday    rainy

    Our school had an English Fun Day today. My classmates and l went to the School Hall to play English games. Some Grade 6 students were helpers and they showed us how to play the games.

    Peter and l were in a spelling(拼写) game. He made many mistakes but I did very well. I got some sweets and we shared(分享) them.

We did not like the matching(配对) game. We had to match some words to pictures. It was not difficult but boring.

    We liked the reading game. I was slow when I read out the sentences. But Peter was very quick. He won the first prize. Miss Wong gave him a photo album. He can put his photos in. We had a good time.
