1. 认识这个词（基础篇）
词：untouched
英英释义：not changed, damaged, or affected in any way
例句：His life remains untouched by his new-found wealth.
2. 体会这个词 （进阶篇）
“untouched”是形容词，来自我们熟悉的动词 touch，是个容易被低估的好词。untouched 字面意思是“不被触摸的”，常用来表示“没有变化的”“不受任何影响的”，因此在一些语境中可以替换 change/influence/affect 相关的表达。我们通过几个例子掌握它的用法。
比如一个人一下子赚了许多钱，但是并没有被财富冲昏头，他的生活并没有什么改变：
His life remains untouched by his new-found wealth.
比如某古镇风景优美，但是还没有成为旅游胜地，当地文化生活几乎没有受到旅游业的影响，我们就可以说：
The ancient, picturesque village remains relatively untouched by tourism.
科技改变了许多行业，除了用 change 表示这句话，我们还可以说：
Few industries have been left untouched by the influence/impact of technology.
《经济学人》中也经常用到 untouched：
1）The firm has been relatively untouched by the current backlash against tech firms, and is less vulnerable to new regulation.（这里的 untouched 和 less vulnerable to 意思相近，可以一起记下来）
2）Melville jumped ship at Nuku Hiva, in the Marquesas Islands, and spent a month with a tribe untouched by Western influence.
3）Ironically, populists have been relatively untouched by scandal, either because they control the judiciary and the media or because a halo of the saviour of the people surrounds them.
3. 从认识到会用（作业）
1）翻译下面的句子： 她没有受周围生活的影响。
She was untouched by the life around her.
（参考翻译：She was untouched by the life around her.）
2）结合自己的生活、学习、工作、兴趣等，想象在什么语境下会用到这个表达。先简要描述这个场景，再造句。
他并未受到肇事者的影响而继续发表自己的演讲。
He had been left untouched by the influence of the perpetrators and continued to express his speech.
