这是最新的一期经济学人上的一个段落。美国的经济是否复苏，不同的专家有不同的看法。这篇文章的核心观点就在这一段。一共四句话，都不长，但是是一个完整的意群。循序渐进哦。。
america has some of the world’s most impressive manufacturing facilities. but talk of “renaissance” is certainly overblown. growth is being driven by a small number of industries, which are hiring few new workers.
and even high-tech operations, at which america should excel, are struggling.
词汇突破：1. facilities 设备，能力。
2. impressive令人印象深刻的(一般表语的时候就是形容一个人和事优秀)
3. manufacturing 制造业。
4. renaissance 复兴。
5. overblown 被夸大的。
6. industry 工业（产业）
7. excel at 擅长 （还有一个搭配是 excel in,是一个意思）
8. struggling 挣扎 （通常就是指境遇不好）
解析：第一句：
america has some of the world’s most impressive manufacturing facilities.
美国拥有某些世界上最为优秀的制造设备。
第二句：but talk of “renaissance” is certainly overblown.
但是“复兴”这种说法确实言过其实了。
第三句：growth is being driven by a small number of industries, which are hiring few new workers.
增长是由一小部分产业带来的，这些产业基本没有雇佣新的工人。
注释：是否促进就业人口增加是产业复苏的标志之一）
第四句：and even high-tech operations, at which america should excel, are struggling.
切分为两句：
1. at which america should excel
america should excel at high-tech operations.
2. and even high-tech operations are struggling.
美国应该擅长高技术含量产业，但这些产业也还在苦苦挣扎。
