One of the objects “asking myself”(a gerund phrase) contains a noun clause “what all the fuss was about” which functions as the direct object of “asking”.

Adverbial modifier: the prepositional phrase “without giving me anything positive”

modifying the main verb “set”

Attributive modifier: “put in the place of that h eady patriotism”(an infinitive phrase) modifying “anything positive”.

Unit1 翻译 1) 发言人(spokesman)明确表示总统在任何情况下都不会取消(cancel)这次旅行。 The spokesman made it clear that the President would not cancel the trip under any circumstances. 2) 杰克对书架上那些书一本也不了解,所以他的选择是很随意的。 Jack didn't know anything about any of the books on the bookshelf, so his choice was quite arbitrary. 3) 随后发生的那些事件再次证明了我的猜疑(suspicions)是对的。(confirm) The subsequent events confirmed my suspicions once again. 4) 我认为我们应该鼓励中学生在暑假找临时工作。 I think we should encourage high school students to find temporary jobs / employment during their summer holidays. 5) 令我们吃惊的是,这位常被赞为十分正直的州长(governor)竟然是个贪官(corrupt official)。 To our surprise, the governor who had often been praised for his honesty turned out to be a corrupt official. 6) 少数工人得到提升(be promoted),与此同时却有数百名工人被解雇。 A few workers were promoted, but meanwhile hundreds of workers were dismissed. 7) 如果有机会,约翰也许已成为一位杰出的画家了。(given) Given the chance, John might have become an outstanding painter. 8) 数小时后,有人看见那个男孩在林子里瞎转。 Several hours later, the boy was found wandering around in the woods. ?

A major medical breakthrough may illustrate the point. Scientists had intended to find a cure for smallpox, but they got nowhere. Edward Jenner, a British physician, abandoned the quest for a cure and conquered the disease by finding a way to prevent it. Obviously, it was creative thinking that led to his fruitful work. In short, it definitely pays to keep this in mind: there is more than one way to look at / view volumes of data you download. ?
