Some people think only best students should be rewarded. Others think we should reward students who make progress. Discuss both views and give your own opinion.
Never has the topic concerning education failed to attract public attention. However, when it comes to whether students with great progress or those academically-superior ones should be rewarded, people hold divergent opinions. From my perspective, these two views are not exclusive, all students deserve to be awarded when they get excellent performance.

As the world's population grows in number, governments are finding it difficult to allot enough funds to sections of the society that are of most importance. While some say that activities meant for recreation are crucial and should receive money from the authorities, others, along with myself, disagree as there are other sectors that lack funding and should be looked at instead.

Some people say free time activities for children should be organized by parents. Others say that children should be free to choose what they do in their free time. Discuss both views and give your opinion.
In our contemporary era, it is acknowledged by some people that children's spare time activities should be managed by adults, while others argue that they need to have the freedom to choose themselves what to do. In my opinion, giving flexibility to youngsters could be more beneficial in terms of creating a positive atmosphere and enhancing stronger family relationships.
