Question

【題目】 Pigeons (鴿子) may be considered mice of the sky, but some scientists have found greater value in these urban birds: the blueprint for a new generation of flying machines.

Birds can transform the shape of their wings by fanning out their feathers or moving them closer together. Those adjustments allow birds to cut through the sky more flexibly than rigid drones (無人機). Now, using new insights into exactly how pigeons ‘joints control the spread of their wing feathers, researchers have built a robotic pigeon. This research paves the way for creating more light aircraft, says Dario Floreano, a roboticist in Switzerland not involved in the work.

“What’s really cool about this robot is that you can make adjustments in a robotic wing that you could never do when studying flight in a bird”, says David Lentink, an engineer and biologist at Stanford University. A controllable robotic pigeon solves that problem. In flight tests, Lentink’s team observed that bending only the fingers of one wing eased the robot into a banked turn-offering the first evidence that birds may sometimes use just their fingers to direct in flight. In a second study, Lentink’s group used their robotic wing design to confirm another insight into bird flight: how gaps are prevented from forming between feathers on extended wings.

This is the best set of robotic wings yet for testing how birds adjust their flight feathers to move through the air, says Tyson Hedrick, a biomechanist. But “there’s plenty of room for improvement.” For instance, a future flying robot could include a shoulder joint to investigate how waving a bird’s wings up and down influences flight, he says.

【3】What do the underlined words “that problem” in paragraph 3 refer to?

A.Pigeons in flight can hardly be observed.

B.People can’t make adjustments in birds’ wings.

C.It is difficult for pigeons to make a banked turn.

D.Pigeons fail to control the spread of their wing feathers.

【4】Where does the text probably come from?

Answer 1

【答案】

【1】D

【2】B

【3】B

【4】D

【解析】

這是一篇說明文。文章主要介紹了利用對鴿子的關(guān)節(jié)如何控制翅膀羽毛伸展的新見解，研究人員已經(jīng)建造了一個機器鴿子，這是一套用于測試鳥類如何調(diào)整飛行羽毛在空中移動的機械翅膀，能夠有效幫助科學(xué)家研發(fā)出新一代的飛行器。

【1】細節(jié)理解題。根據(jù)文章第一段內(nèi)容“Pigeons may be considered mice of the sky, but some scientists have found greater value in these urban birds: the blueprint for a new generation of flying machines.”可知一些科學(xué)家發(fā)現(xiàn)鴿子的價值在于它們是新一代飛行機器的藍圖。故選D項。

【2】推理判斷題。根據(jù)文章第二段末尾句內(nèi)容“This research paves the way for creating more light aircraft, says Dario Floreano, a roboticist in Switzerland not involved in the work.” 可知，在Dario Floreano來看，這項研究為制造更多的輕型飛機鋪平了道路，因此可推知他對這項研究的態(tài)度是支持的。故選B項。

【3】詞義猜測題。根據(jù)劃線短語“that problem”可知，that為指示代詞，指代前文提及的內(nèi)容。因此that problem 應(yīng)是指代前文：“What’s really cool about this robot is that you can make adjustments in a robotic wing that you could never do when studying flight in a bird”, says David Lentink, an engineer and biologist at Stanford University.( 斯坦福大學(xué)的工程師和生物學(xué)家David Lentink說：“這個機器人的最酷之處在于，你可以調(diào)整機器人的翅膀，而這在研究鳥類飛行時是無法做到的�！�)提到的人類無法做到的問題：人類無法像機器人一樣在研究鳥類飛行時調(diào)整鳥的翅膀。故選B項。

【4】推理判斷題。根據(jù)文章的核心主題為“a robotic pigeon”，因此可知，文章應(yīng)是科普類文章，應(yīng)是刊登在科普雜志上。故選D項。

人物性格、態(tài)度及觀點判斷題：高考閱讀測試中有些是考查考生對作者的主導(dǎo)思想、被描寫人物語氣、言談話語中流露的情緒、性格傾向和作者或文中人物態(tài)度、觀點等方面的理解題。做這一類題時一定要注意：由表及里的準確把握字里行間的意思，切勿用自己的主觀想法或觀點代替作者的思想觀點；特別注意那些描寫環(huán)境氣氛的語言，以及表達感情、態(tài)度觀點的詞語。要特別注意作者在文章中的措詞，尤其是表達感情色彩的形容詞；能結(jié)合自己平時積累的有關(guān)英語國家的文化傳統(tǒng)、風(fēng)俗習(xí)慣等背景知識來識別評價。比如文章的第2小題：

2. What is Dario Floreano’s attitude to the research?

A. Negative. B. Positive. C. Neutral. D. Critical.

根據(jù)題干可知，應(yīng)是態(tài)度推理判斷題。結(jié)合原文“This research paves the way for creating more light aircraft, says Dario Floreano, a roboticist in Switzerland not involved in the work.”可以看出一些表達態(tài)度觀點的短語：paves the way(為……作準備；為……鋪平道路)，應(yīng)是積極的態(tài)度。因此答案為B項。
