【语篇导读】本文是一篇说明文。文章介绍了三个有利于心理健康的实用方法。
1. C 设空前表明我们中的许多人会在某个阶段经历心理问题，该空需要说明我们可能会面对的心理问题，以承上启下，C项（压力、失望和灾难可能都会有）符合语境。
2. A 设空前表示一些预防措施可以帮助我们度过困难时期。再根据下面三段内容可知，该空是总领下文的句子，A项（这里有三个实用的步骤）总领下文，符合语境。

三、应用文写作
One possible version:
Mobile phones bring us much convenience and have become part of our life. However, more and more phubbers, especially young people, would like to stare at their smartphone screens anytime and anywhere, whether they are riding in a bus, eating at a dinner table or walking across a street. They never care about what happens around.
As far as I am concerned, the habit should be got rid of. First, it does harm to people’s health, especially the eyes. Besides, it is dangerous while people are crossing the street. What’s more, on some occasions it seems impolite.
In a word, people should make good use of mobile phones instead of becoming addicted to them.
