Mary
As for me, I believe “Waste not, want not．” We know there are still millions of Chinese living in a  poor condition．We can never afford waste．Therefore, it is no doubt that saving is still a good habit that we should not give up．I do not like the men who spend their money in a wrong way．They do not know waste is a bad thing．It can only make them happy for the time being．
Jacky
More and more people are no longer interested in the simple life style, including me．And I feel embarrassed to save the things I used．What I love is the latest fashion．In my eyes, saving is already out of style．
Sally
One of the best ways we students can do in this situation is to recycle the textbooks we are using every day．After we’ve used them and are moving on to new ones, we should find ways to recycle these books instead of simply throwing them away．There are different ways to do so, such as sending them to a recycling factory, reusing them for other purposes, passing them on to new students and so on．
Tim
The negative effects（负面影响）of waste can be shown as follows．Firstly, it makes some students ask their parents for money quite often, which is harmful to their development．If they don’t learn to support themselves, they will be “useless people” when they graduate．Secondly, it is not easy for our parents to arrange for our schooling．Last but not the least, just like what Mary said that our country is still poor．There are many people who cannot go to university and many poor people still need our help．
