3) Therefore, it is high time that we take measures to stop wasting.

参考答案:

Wasting has become a serious problem in many campuses. Just take a look around, and we can find lots of examples. In the canteen, much food is left in the plates or dumped into the dustbin. In the classroom or library, blank or half blank pieces of paper can be found on the desks or grounds. In the dorm building, taps are left open and water left running or dripping all the time.
Wasting has brought about severe consequences if we turn a blind eye to it. On the one hand, it puts pressure on the resources in shortage such as food, water and electricity. If we continue wasting them instead of saving them, we will receive retribution from nature sooner or later. On the other hand, this kind of lifestyle goes against traditional virtue of frugality, which may corrupt one’s soul and harm the society.
Therefore, it is high time that we take measures to stop wasting. For one thing, we should strengthen the awareness of saving resources by doing trifles around. For example, switch off the light when we leave the room. For another, regulations or laws on punishment for wasting should be made and enforced.
