【优秀满分范文】
we had an exam yesterday and now the papers are being handed out. There’s a paper without a name on it and that student got full marks.
Whom can it belong to? It can’t be a boy’s, because none of them in class can be so good and tidy. The paper must belong to a girl because its handwriting is very tidy. There are only three girls who are good at handwriting — Rose, Mary and Lucy. It might belong to Rose, but I’m not sure because she is not so good at English. It can’t be Mary’s. Although she is a top student in English, she has already had hers in hand. So it must belong to Lucy. Today she is ill at home and she does well in English, too. Well, it must belong to her.
