    It is spring, the good time to enjoy the beautiful nature. Our shcool is plannig to organize a spring outing for the students. As a Senior Three student, I appreciate it if we can have a chance to go for an outing.

    As is known to us all, Senior Three students are occupied with heavy studies. We seldom have the opportunity to get close to nature. Enjoying the beautiful nature can not only make us relax ourselves, it is benefical to our students as well.

    Besides, it can broaden our knowleged, for while going around, we can learn a lot of what we can not learn from our textbooks.

In a conclusion, a wonderful outing will be a sweet memory to us forever.

It is spring, the good time to enjoy the beautiful nature. Our school is planning to organize a spring outing for the students. As a Senior Three student. I don't think it good to go for an outing.

As is known to us all, we are occupied with onr studies every day.  We seldom have extra time to do  other things.  Having a spring outing is a waste of time and money. In addition，we can hardly concentrate on our studies immediately after the outing，which may lead to a bad effect.

What's more，the outside world is full of unexpected things，which may result in some terrible accidents. So as for me, it's better to stay at school and concentrate ourselves on our studies.
