【语篇写作】
应用文写作
最近你班同学就“人类是否应该进行宇宙探索”这个问题进
行了激烈的讨论。
有人认为,探索宇宙不仅让人类更好地了解宇宙的发展,还
可以用来进行农业实验,以及把一些探索太空的高新技术用于现
实生活中;但也有一些人认为探索太空花掉了大量的人力和物力,
影响了人们的生活水平。
请你根据以上情况写一篇报告并发表自己的观点。
注意:
1.写作词数应为 80 左右;
2.可适当增加细节,以使行文连贯。
参考范文:
Recently we have held a heated discussion about the issue
whether mankind should explore space or not.Different people have
different opinions.
Some people hold the view that space exploration will not only
enable us to understand how the universe develops but also help
farming by doing agriculture experiments and apply the new
technology to our life.While other people argue that we should stop
exploring space because it costs too much time and energy.
From my point of view, it is very necessary for humans to
explore space, because it can not only provide the world with many
different benefits, but also solve people's short-term and long-term
problems.
