承接上文，来自2013年考研真题·第三篇阅读的一句话
先试着自己读一下：
Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change.
1.语法讲解
句式结构是【...has done..., as ...... 】，随着....，某某某怎么怎么样
from... to....，表示范围，是标准的举例模板，可用于作文中的举例处
2.语言点讲解
①utopia [ju:'təupiə]
“乌托邦”，理想世界，也就是我们中文所说的【世外桃源】
(an imaginary perfect world where everyone is happy)
②grow adj. 【变得】
等于become，不过耗时更长，强调【渐渐】这个概念，就像植物生长一样，不是一下就开花结果
The skies grew dark and it began to rain.
天渐渐黑了,又下起雨来。
The air had grown thick and smoky.
空气变得混浊，烟雾弥漫。
③unfashionable “过时的，不流行的”
(not popular or fashionable at a particular time)
④appreciation
第一个意思是大家比较熟悉的义项【欣赏】
第二个意思是【理解，了解】，算是熟词僻义了
understanding of what sth involves
The course helped me to gain a deeper appreciation of what scientific research involves.
这门课程帮助我更深入地了解科学研究所包含的内容。
I had no appreciation of the problems they faced.
我没有理解和体谅到他们所面临的困难。
⑤asteroid ['æstərɒɪd] 【小行星】
(one of the many small planets that move around the sun, especially between Mars and Jupiter)
句中asteroid strike指【行星袭击】
去掉首字母a就是steroid 【类固醇】
类固醇 ≈ 兴奋剂，
举重运动员有时会非法服用类固醇增强肌肉和力量。
作用就像大力水手吃的菠菜，
相关表达sth on steroids，
某事物像服用了类固醇，或者兴奋剂一样 = 其比一般的更强大，更厉害，
延伸出来一个句型 A is B on steroids.
A是升级版/强化版/进化版的B
●TikTok is YouTube on steroids.
TikTok就像是打了兴奋剂的YouTube
●Iphone Iphone X is Iphone on steroids.
Iphone x 是升级版的
⑥epidemic [epɪ'demɪk] 【流行病】
(an epidemic of a particular disease somewhere affects a very large number of people there and spreads quickly to other areas)
=infectious disease 互为同义替换
Even if a vaccine were ready within a year, it would be too late to stem the current epidemic in China.
即使能在一年内推出疫苗，对于遏制中国当前的疫情也为时已晚。
—— The Economist, 2020.2.8
再来回顾一下这个句子
Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change.
