参考答案：One possible version

We held a discussion about whether to shorten (缩短) the summer and winter holidays and add the spring and autumn holidays last week. Opinions are different.

Some students think that the terms are long and boring at present and students can't get enough rest. Spring and autumn have beautiful views. If the spring and autumn holidays are added, students will have more chances to feel the beauty of the nature.

Some students think if we add the spring and autumn holidays, a year will be divided into four terms and it will have bad effect on teaching and learning. If so, students may have more homework to do and get more pressure to face.

I don't think we need to add the spring and autumn holidays, but we need more holidays without too much homework. It will be better for students to have more time for their hobbies.
