Recently, a survey has been made in our school on whether you want a little brother or sister. The opinions are different.
Here are the results: 40% of the students want a little brother or sister, because they think that they won't feel lonely any more, and if they have a little brother or sister, they will help each other and share the happiness and sadness with each other. What's more, they think they will get more freedom, because their parents will not pay all their attention to them.
范文赏析
But the rest of students disagree with this point. They worry about the little brother or sister will take away the love of their parents. They are also afraid that their little brother or sister will bother their studying.
In my opinion, it is hard to say whether it is good or bad to have a brother or sister, but we should respect our parents' choices. After all, they are the persons who should make the final decision.
本文运用了“三部曲法”写一份调查报告，首先，开篇点题，然后，陈述他人的观点；最后阐述自己的观点。全文层次分明，行文连贯，语言丰富。
添彩点：①运用短语“not ...any more", "feel lonely” 表达赞成原因之一； ② 运用“help each other", "share happiness and sadness”短语表达赞成原因之二；③运用“take away the love”表达反对原因之一；④运用“bother their studying”表达反对原因之二；⑤过渡性词语“What’s more”和“In my opinion”的运用使文章自然流畅。
