Below is a chart showing the global water supply. Write an essay of about 120 words making references to the following points:
1) describe the percentage of different kinds of water supply of the world;
2) analyze the current situation of fresh water on earth;
3) give the possible reasons for this situation.
Water is a precious resource. Although we are surrounded by it in oceans, lakes, rivers and streams, our supply is limited. The chart given shows that most of the water on earth — 97.4 percent — is salt water stored in oceans. Only 2.6 percent of the earth's water is fresh water, and 2 percent is locked up in ice caps and glaciers. Thus the fresh water left for us to use is only 0.6 percent of the total water supply.
There will never be any more fresh water than there is now. In fact, the earth is short of fresh water. Besides, the increasing growth of the world population, the growing demand of industry for water, the serious pollution of our environment — all this makes the world in danger of running out of fresh water. In some large cities such as Tianjin, fresh water cannot meet the daily needs.
Since water is essential to all life and the supply limited, we must manage it intelligently and carefully.
A survey conducted in Tianjin found that 98% of high school students and 92% of elementary school students have to spend most of their weekends doing homework.
Write an essay of about 120 words. You may include the following points:
1. Discuss the negative effects of too much homework on children.
2. Discuss the disadvantages of the present exam-oriented education system.
3. Call for efforts to ease students' burden and help them lead a colorful and enjoyable life.
Too much homework has become a common complaint in high schools and elementary schools. Students have to spend most of their time doing homework, even on weekends. As a result, they have no time for their hobbies, or for their parents or friends. All they do is what they have to do, not what they like to do.
The underlying cause for this phenomenon lies in the present exam-oriented education system. National College Entrance Examination has become the sole focus of teachers, parents, and students themselves. High score becomes the ultimate goal, to the neglect of practical abilities, personality development, and all that.
It is urgent that we deepen our educational reform. We must allow for students' overall development, not just evaluate their test scores.
As is known to all, computers are becoming more and more popular in our daily life nowadays, especially in education. Write a short essay of about 120 words, describing how important computers are in education.
It has turned out that computers have become quite indispensable to education. With computers, students can do their homework more quickly and more efficiently; with computers, teachers can reduce their work load and improve their teaching.
For instance, computers can free teachers from certain kinds of time-consuming bookkeeping; help teachers "bank" test items, thus greatly reducing the time required to produce a new test, and mark test papers. More importantly, they can analyze test results, indicating to the teacher which points may need further treatment in class. They can also make it possible for a teacher in the classroom to give individual attention to students who are having trouble in their studies. While the rest of a class is working on an educational program, the teacher can take the time to work directly with a student who is falling behind. So it goes without saying that computers are extremely important in education at all levels.
