书面表达

说明文
Is It the Only Way Out To Go To College ?
   We had a discussion about whether it is the only way out for senior students to go to college.Views vary from person to person.
The majority of us consider it very necessary to go to college.They think it can widen their knowledge and improve their qualities.Only in this way can they find better jobs after graduation.Very few students, that is about ten percent of the students think it no use going university, because the tuition is too high for their family to afford.What’s more, it’s rather hard for college graduates to seek satisfactory jobs.Thirty percent of the students, however, believe “All roads lead to Rome.” Therefore it doesn’t make any difference whether they go to college or not.
   In my opinion, we can receive a better education at college so that we can serve our motherland.
My magic pen
I have been thinking about inventing a magic pen for many years.
Every time when I see my classmates doing their home work with frustration and tiredness, how I want to give their some help and bring some relaxation to them; every time when I notice my teacher writing on the blackboard with great efforts and wiping his handwriting off the blackboard with a dusty hand, how eager I am to offer him some help and make him enjoy the happiness of teaching without dust.
After many errors and trials, today, I at last make it. I add some new functions to my usual pen.
Pressing the blue button, the users can enjoy some relaxation after a tiring and boring writing by listening to some beautiful songs, soft music, funny stories and radio programs for one or two minutes through a special earphone. Switching on the “T” button, which is intended for teachers, users can write smoothly on the blackboard at the same place time and time again, as the handwriting will be cleared up automatically when users write at the same place for a second time.
I feel happy with my magic pen but I cannot enjoy the magic smiles on my classmates and teachers` faces too much!

I recently surveyed my classmates about their views on the new English textbook. According to the survey, 80% of the students were quite satisfied with it, while 15%disliked it and 5% had no opinion.
Students who liked it said the pictures with the texts were very attractive, which greatly aroused their interests in learning.
Moreover, the book was very interesting, covering many hot topics and providing lots of cultural knowledge of the world. However, students who disliked it complained there were too many new words and difficult sentences,making the texts difficult to understand.
In conclusion, the new English textbook has helped most students improve their English enormously.
As is apparently shown in the chart above, many middle school students have problems both physically and mentally, with 70% of the students having learning anxiety as well as poor eye-sight, and a large percentage lacking sleep. Coming next is the lack of physical exercise. 40% of the students surveyed won’t obey their parents or teachers. In addition, still fewer claim not to have enough communication with others .
As far as I am concerned, we students should balance our physical exercise and studies. Just as a saying goes: “All work and no play makes Jack a dull boy”, without a sound body, one cannot achieve anything. However, too much attention has been paid only to studies.
Therefore, I suggest we be given less homework and more time for out-of-classroom activities to solve all the problems. Only in this way can we lead a happy and healthy life.
