As is know, when senior students graduate from school, most of their textbooks are thrown away, which are still in a good condition. What a waste it is! I quite agree to the suggestion we should recycle these textbooks. For one thing, recycle textbooks can save a lot of natural materials, which is used to make textbooks. For other, senior students may have plenty of useful notes over the pages. They are very helpful to those textbook users. What’s worse, the cost of the books will unload some burden of the families of the students. Actually in Australia and any other countries, recycling textbooks is popular but it gives us a good example. Why can’t we have a try? | 76. 77. 78. 79. 80. 81. 82. 83. 84. 85. |
