1. 认识这个词（基础篇）词：trouble
英英释义：to cause inconvenience or discomfort to
例句：He was troubled by his health.
2. 体会这个词 （进阶篇）
我们都知道“trouble”是“麻烦”，不过我们这里要学习的是它的动词形式，表示“让某人感到痛苦或焦虑”。我们在口语和写作中都能用到它。
在口语中，我们想麻烦别人做某事时，可以先客气地说一句：I’m sorry to trouble you…
在写作中，trouble 是一个经常被低估的、想不到词。例如当我们想表示“担心”时，可能一下子能想到 worry，concern，其实这时候也可以用 trouble。
比如很多学生有无法集中注意力的问题，就可以说：
Many students today are constantly troubled by their inability to concentrate.
再比如，信息过载给很多人带来了压力，结果是很多人会买一些他们并不需要的线上微课，就可以说：
People are increasingly troubled by overload of information so much so that they end up buying many online mini-courses that they do not actually need.
很多国际一线城市交通堵塞严重，我们就可以评论说：
Many international cities, say Los Angeles, Beijing, and New Delhi, are troubled by traffic congestion.
3. 从认识到会用（作业）
1）翻译下面这句话：
What troubles many second-tier cities the most is the lack of talent.
最困扰很多二线城市的是人才的短缺。（参考翻译：What troubles many second-tier cities the most is a shortage of talent.）
2）结合自己的生活、学习、工作、兴趣等，先想象在什么语境下会用到这个表达，然后再进行造句。
场景：范思哲的爱人安东尼始终得不到范妹妹的认可
造句：What had been troubling Antonio was that he could not be acknowledged by Donatella, the most closed family of Versace, from the very beginning to the end. After his lover's death, with a crippled heart, he commited suicide, finally proving his pure and deep love for him.
